The IBM Systemz9 109 (z9-109) (announced July 2005), provided a strong combination of mainframe characteristics, plus newfunctions designed around scalability, availability, security, and virtualization. With the announcement in Mayof 2006, the z9-109 became known as the IBM System z9 Enterprise Class (z9 EC).With a modular book design, the z9 EC Model S54 is designed to provide up to 95% more total system capacitythan the z990 Model D32, and has up to double the available memory. The Modified Indirect Data AddressWord (MIDAW) facility is designed to improve FICON performance. The number of FICON Express2 openexchanges (concurrent I/O operations) that may be active simultaneously has been increased from 32 to 64per channel.The z9 is focused on providing higher availability and reducing planned and unplanned outages -- which, whenproperly configured, may be accomplished with improved nondisruptive replace, repair, and upgrade functionsfor memory, books, and I/O as well as extending nondisruptive capability to download Licensed Internal Codeupdates.Integrated clear key encryption security-rich features on the z9 include support for Advanced EncryptionStandard, Secure Hash Algorithm-256, and integrated Pseudo Random Number Generation. Performing thesefunctions in hardware is designed to contribute to improved performance.Innovations on the z9 can help to ensure you have a security-rich platform, can help maximize your resourcesand their utilization, and can help provide you the ability to integrate applications and data across theinfrastructure. The z9 is designed to be a flagship component of your heterogeneous environment.The z9 continues the evolution of the mainframe, building upon the structure introduced on z990 in support ofz/Architecture, reliability, availability, scalability, and clustering. The z9 expands upon a key attribute of theplatform - availability - to help ensure you have a resilient infrastructure designed to satisfy the requirements
  • 7. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 7 of 82of On Demand Business. With the increased performance and total system capacity possible for the z9, youhave an opportunity to continue to consolidate diverse applications on a single platform.The z9 EC is designed to provide:• Five New Hardware Models - offering 1 to 54 configurable PUs. The first four models (S08, S18, S28and S38) have 12 PUs per book. The enhanced capacity Model S54, our largest mainframe server, offers 16PUs in each of its four books.• Faster Uni processor - a 35% increase in capacity performance over the z990 Model 2084-301, and theoverall server capacity will be 95% more on the S54 than the z990 Model 2084-332.• Up to 54 CPs - The Model S54 is an enhanced capacity model. You can customize the machine to be a 1 to54-way. On the standard models, the first book has 10 configurable PUs, with 12 PUs each in books 2, 3and 4. The S54 has 12 configurable PUs in the first per book, and 14 configurable ones in each remainingbook. Like the S38, the S54 can be ordered with a minimum of 16 GB of memory up to a maximum of 512 GB.• Up to 512 GB Memory - Memory has been doubled from what was offered on the z990 processor - for aserver maximum capacity up to 512 GB with a maximum of 128 GB per book.• CBU for IFL, ICF and zAAP - The z9 will be able to activate most PU types as part of CBU upgrades:IFLs, zAAPs, ICFs and CPs (zIIPs added with GA2). This is in contrast to the z890 and z990 servers thatwere, and continue to be, only able to activate CPs as CBU upgrades.• Separate PU Pool Management - New on the z9, all zAAP, zIIP, ICF and IFL processors will be managedas individual separate and distinct processor types/pools by PR/SM. On the z990 all the specialty engineswere contained in just one ‘specialty pool’.• Redundant I/O Interconnect - Redundant I/O interconnect will help maintain critical connections todevices during enhanced book availability as it provides connectivity to the server I/O resources using asecond path from a different book.• Enhanced Driver Maintenance - One of the greatest contributors to downtime during planned outages isLicensed Internal Code (LIC) updates performed in support of new features and functions. When properlyconfigured, the z9 is designed to support activating select new LIC level concurrently. Concurrentactivation is only supported at specific sync points.• Enhanced Book Availability - The z9 is designed to allow a single book, in a multibook server, to beconcurrently removed from the server and reinstalled during an upgrade or repair action.• Dynamic Oscillator Switchover - The z9 has two oscillator cards, a primary and a backup. In the event ofa failure of the primary oscillator card, the backup is designed to detect the failure, switch over, andprovide the clock signal to the server transparently. Previously, in the event of a failure of the activeoscillator, a server outage would occur, the subsequent Power On Reset would select the backup, and theserver would resume operation. Dynamic oscillator switchover is exclusive to the z9.• Server Time Protocol – (available since January 31, 2007) Is a new time synchronization feature, ServerTime Protocol (STP), which is designed to provide the capability for multiple System z9 and zSeries serversto maintain time synchronization with each other. STP is planned to be the follow-on to the Sysplex Timer(9037-002). The Sysplex Timer and STP are designed to allow events occurring in different System z9,zSeries, and S/390 servers to be properly sequenced in time. Note: IBM intends to withdraw the SysplexTimer Model 2 (9037-002) from marketing in 2006. For more information, refer to HardwareAnnouncement 105-241, dated July 26, 2005, (IBM System z9 109).STP is designed to:• Allow clock synchronization for z9 EC, z9 BC, z990, and z890 servers and CFs without requiring theSysplex Timer• Support a multisite timing network of up to 100 km (62 miles) over fiber optic cabling, thus allowing aParallel Sysplex to span these distances
  • 8. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 8 of 82• Potentially reduce the Cross-Site connectivity required for a multisite Parallel Sysplex• Coexist with an ETR network• Allow use of dial-out time services to set the time to an international time standard (such asCoordinated Universal Time (UTC)) and adjust to UTC on a periodic basis• Allow setting of local time parameters, such as time zone and daylight savings time• Allow automatic updates of daylight savings timeSTP is available as a feature on z9, z990, and z890, and be supported by z/OS (and z/OS.e) V1.7 (PTFs arerequired to enable STP support).• Faster 2.7GB STI and more of them - The z9 has 4 more STI (self timed interconnect) connections perbook as well as a faster bandwidth. (12 STIs x 2.0 Gigabytes per STI x 4 books = 96 versus 16 STIs x 2.7GB per STI x 4 books = 172.8 ... 172.8/96 = 80%)• MIDAW Facility - The Modified Indirect Data Address Word (MIDAW) facility is a new and separatefacility, offering an alternative for a channel program to be constructed. The new design can help toimprove performance for native FICON applications that use extended format datasets (including DB2 andVSAM) by helping to improve channel utilization, reduce channel overhead, and improve I/O response times.The MIDAW facility is supported on z/OS 1.6 and above.• Multiple Subchannel Sets (MSS) per LCSS – MSS provides a second set of subchannels for definingParallel Access Volume (PAV) aliases. This new function can help provide relief from the 64K device limitby allowing PAV aliases to be defined without making device numbe3rs unavailable for defining additionaldevices. For some of our largest customers this is designed to provide an I/O constraint benefit.• 63.75K Subchannels for Set-0 - addresses a maximum of 64K-1 subchannels in subchannel set 0 (zero).Previously 1024 (1K) of these subchannels were reserved for system use. IBM is making 768 of thesesubchannels available for customer use. This change increases the storage attachment capability of theSystem z9 - for example the IBM TotalStorage DS8000 Series can be defined to attach 63.75K unitaddresses - so with 63.75K in the host there is symmetry between the server and the storage subsystem.• Up to 336 FICON Express2 Channels - Providing the capability to populate the 28 I/O slots in one I/Ocage allows the z9 to have a maximum of 336 FICON channels installed.• N_Port Virtualization N_Port ID Virtualization (NPIV) allows a single Fibre Channel Protocol (FCP) porton Linux on System z9 to appear as multiple, distinct ports providing separate port identification andsecurity zoning within the fabric for each operating system image as if each operating system image had itsown unique physical port. NPIV is similar to the Multiple Image Facility (MIF) available on ESCON andFICON channels.• IPv6 Support for HiperSockets - HiperSockets now supports Internet Protocol Version 6 (IPv6) designedby the Internet Engineering Task Force (IETF) to replace Internet Protocol Version 4 (IPv4) to helpsatisfy the demand for additional IP addresses. IPv6 provides more unique IP addresses by expanding theIP address space from 32 bits to 128 bits. IPv6 requires z/OS 1.6 and z/VM 5.2.• OSA-Express2 1000BASE-T - With the additional memory available on OSA-Express2, the 1000BASE-TEthernet feature will be able to: Support large send (offloading TCP segmentation processing from hostTCP/IP stack to OSA-Express2), 640 TCP/IP stacks for improved virtualization by hosting of more imageson System z9 and potentially reducing the number of required OSA features, and support of concurrentLIC update to minimize network traffic disruption.• OSA-Express2 OSN (OSA for NCP) - The OSA-Express2 OSN (OSA for NCP) is designed to providesupport for the IBM Communication Controller for Linux (CCL) on System z V1.2.1. OSA for NCP will helpto eliminate dependencies on hardware such as the 3745/6. It helps to collapse SNA within the serverwhile exploiting and leveraging IP.

A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 9 of 82• Enhanced CPACF with AES, PRNG and SHA-256 – CP Assist or Cryptographic Functions (CPACF) hasbeen enhanced to include support of the Advanced Encryption Standard (AES) for 128-bit keys, SecureHash Algorithm-256 (SHA-256), and Pseudo Random Number Generation (PRNG). PRNG is a standardfunction supported on the Crypto Express2 feature. CPACF, supporting clear key encryption, is standard onevery CP and IFL; however a no charge enablement feature #3863 is required.• Configurable Crypto Express2 – The Crypto Express2 feature has two PCI-X adapters, and each can bedefined as either a coprocessor or as an accelerator. The Crypto Express2 feature with both PCI-Xadapters defined as accelerators is designed to perform up to 6000 SSL handshakes per second. That is a3X performance improvement compared to the z990 when using either a PCI Cryptographic Accelerator(PCICA) feature, with two PCI accelerators per feature, or the current Crypto Express2 feature, with twoPCI coprocessors per feature.

Realizing the requirement for more granular capacity settings within the z9 EC,now offers you central processors with a larger variety of capacity choices that can help meet your businessrequirements. These processors will continue to have the ability to support all z9 EC features and functions.The mainframe has evolved our use of specialty engines over time starting with the Internal Coupling Facility(ICF). The latest specialty engine, announced in January of 2006, is the zIIP. The IBM zIIP is the latestcustomer-inspired specialty engine for the IBM System z9 family. The zIIP, when combined with an enablingWeb deliverable for z/OS V1.6 and V1.7 and enabling PTFs for DB2 UDB for z/OS V8, is designed to helpimprove resource utilization and lower the cost of eligible workloads, enhancing the role of the z9 EC as thedata hub of the enterprise.The z9 EC now includes FICON Express4 for potential improved I/O capacity and performance with the nextgeneration of FICON/FCP. This new feature may offer increased channel aggregation and shorter backupwindows to help reduce the cost of storage operations and infrastructure. IBM has a broad range of disk, tape,and SAN products that are ready to support FICON Express4. With these enhanced capabilities, the z9 EC isintended to help increase the flexibility to configure a server to meet current needs, provide a powerful andadvanced data serving environment, and help drive down risks and business costs. The z9 EC is designed tooptimize your resources without sacrificing features or functions, both within the server and within theenterprise.
  • 11. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 11 of 82Additionally, the z9 EC includes support for Remote Key Loading for ATMs and point of sale devices, andimplementation of ISO 16609 CBC Mode TDES MAC.Remote Key Loading refers to the process of loading Data Encryption Standard (DES) keys to AutomatedTeller Machines (ATMs) and Point of Sale (POS) devices from a central administrative site without the needfor personnel to visit each machine to manually load DES keys. These enhancements provide two important newfeatures: the ability to load initial keys to an ATM or a POS device from a remote location, and enhancedcapabilities for exchanging keys with non-CCA cryptographic systems.Remote Loading of Initial ATM Keys: Typically, a new ATM has none of the financial institutions keysinstalled. Remote Key Loading refers to the process of loading Data Encryption Standard (DES) keys toAutomated Teller Machines (ATMs) from a central administrative site without the need for personnel to visiteach machine to manually load DES keys. This has been done by manually loading each of the two clear text keyparts individually and separately into ATMs. Manual entry of keys is one of the most error-prone and labor-intensive activities that occur during an installation, making it expensive for the banks and financial institutions.Remote Key Loading Benefits: • Provides a mechanism to load initial ATM keys without the need to sendtechnical staff to ATMs.• Reduces downtime due to key entry errors.• Reduces service call and key management costs.• Improves the ability to manage ATM conversions and upgrades.Integrated Cryptographic Service Facility (ICSF), together with Crypto Express2, support the basicmechanisms in Remote Key Loading. The implementation offers a secure bridge between the highly secureCommon Cryptographic Architecture (CCA) environment and the various formats and encryption schemesoffered by the ATM vendors. The following are new ICSF services are offered for Remote Key loading:• Trusted Block Create (CSNDTBC) - This callable service is used to create a trusted block containing apublic key and some processing rules. The rules define the ways and formats in which keys aregenerated and exported.• Remote Key Export (CSNDRKX) - This callable service uses the trusted block to generate or exportDES keys for local use and for distribution to an ATM or other remote device.Refer to Application Programmers Guide, SA22-7522, for additional details.Improved Key Exchange With Non-CCA Cryptographic Systems: IBM Common Cryptographic Architecture(CCA) employs Control Vectors to control usage of cryptographic keys. Non-CCA systems use other mechanisms,or may use keys that have no associated control information. This enhancement provides the ability toexchange keys between CCA systems, and systems that do not use Control Vectors. Additionally, it allows theCCA system owner to define permitted types of key import and export which can help to prevent uncontrolledkey exchange that can open the system to an increased threat of attack.ISO 16609 CBC Mode T-DES Enhancement: ISO 16609 CBC Mode T-DES MAC supports the requirementsfor Message Authentication, using symmetric techniques. ICSF will use the following callable services to accessthe ISO 16609 CBC Mode T-DES MAC enhancement in the Cryptographic coprocessor:• MAC Generate (CSNBMGN)• MAC Verify (CSNVMVR)• Digital Signature Verify (CSNDDSV)ISO 16609 CBC mode T-DES MAC is accessible through ICSF function calls made in the Cryptographic AdapterSegment 3 Common Cryptographic Architecture (CCA) code.

The servers andCoupling Facilities that are capable of supporting Server Time Protocol are:• IBM System z9 Enterprise Class (z9 EC)• IBM System z9 Business Class (z9 BC)• IBM eServer zSeries 990• IBM eServer zSeries 890Server Time Protocol is a server-wide facility that is implemented in the Licensed Internal Code (LIC) of z9EC, z9 BC, z990, z890, and CFs and presents a single view of time to Processor Resource/Systems Manager(PR/SM). STP uses a message-based protocol in which timekeeping information is passed over externallydefined Coupling Links - InterSystem Channel-3 (ISC-3) links configured in peer mode, Integrated Cluster Bus-3 (ICB-3) links, and Integrated Cluster Bus-4 (ICB-4) links. These can be the same links that already are beingused in a Parallel Sysplex for Coupling Facility (CF) message communication.By using the same links to exchange timekeeping information and Coupling Facility messages in a ParallelSysplex, STP can scale with distance. Servers exchanging messages over short distance links such as ICB-3 andICB-4 are designed to meet more stringent synchronization requirements than servers exchanging messagesover long distance links such as ISC-3 (distances up to 100 km), where the synchronization requirements areless stringent. This is an enhancement over the current Sysplex Timer implementation, which does not scalewith distance.The STP design has introduced a new concept called Coordinated Timing Network (CTN). A Coordinated TimingNetwork (CTN) is a collection of servers and Coupling Facilities that are time synchronized to a time valuecalled Coordinated Server Time.STP supports the following functions:
  • 15. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 15 of 82• Initialize the time manually or by dialing out to a time service, so that Coordinated Server Time can beset to within 100 milliseconds of an international time standard such as Coordinated Universal Time(UTC).• Schedule periodic dial-outs to a time service so that Coordinated Server Time may be gradually steeredto an international time standard.• Initialize Time Zone offset, Daylight Saving Time (DST) offset, Leap seconds offset.• Schedule changes to offsets listed above. STP can automatically schedule Daylight Saving Time, basedon the selected Time Zone, a capability that did not exist on the Sysplex Timer.• Adjust Coordinated Server Time by up to +/- 60 seconds. This improves upon the Sysplex Timerscapability of adjusting time by up to +/- 4.999 seconds.STP EnhancementsThe Server Timer Protocol feature is designed to simplify hardware configurations by:• Allowing clock synchronization for z9 EC, z9 BC, z990, and z890 servers and Coupling Facilities withoutrequiring the Sysplex Timer and dedicated timer links. This helps reduce the need for separatehardware that needs to be ordered and maintained.• Supporting a multisite timing network of up to 100 km (62 miles) over fiber optic cabling, thus allowing asysplex to span these distances. This overcomes the limitations of the Sysplex Timer to Sysplex Timerlinks being supported only up to 40 km. STP is designed to eliminate the need for a third site to locatethe second Sysplex Timer for installations where the multisite sysplex spans a distance greater than40 km but less than 100 km (the current limit for Sysplex Timer to server connection).• Potentially reducing the cross-site connectivity required for a multisite Parallel Sysplex. Dedicatedlinks are no longer required to transport timing information since STP and Coupling Facility messagesmay be transmitted over the same links.Additional value from Server Time Protocol may be obtained by:• Eliminating infrastructure requirements (space, power, etc) needed to support Sysplex Timers• Eliminating Sysplex Timer maintenance costs• Eliminating fiber optic infrastructure requirements for:o Patch/trunk cableso Dense Wavelength Division Multiplexer (DWDM) portso Dark fiber between sites for External Time Reference (ETR) and Control Link Oscillator (CLO)links (links between Sysplex Timers)Concurrent Migration and CoexistenceSTP introduces the concept of a Coordinated Timing Network (CTN), to meet two key goals of System zcustomers:• Concurrent migration from an existing External Time Reference (ETR) network to a timing networkusing STP.• Capability of servers that cannot support STP to be synchronized in the same network as servers thatsupport STP (z9 EC, z9 BC, z990, z890)A CTN can be configured in two ways:• Mixed CTN (ETR and STP) which requires a Sysplex Timer. The Sysplex Timer provides thetimekeeping information in a Mixed CTN.A Mixed CTN allows you to meet the above requirements of concurrent migration and coexistence. Thecoexistence allows for a sysplex configuration where members of the sysplex may reside on a z800 or z900server.• STP-only CTN which does not require a Sysplex Timer.

To help facilitate resolution, the operating system can now request the RNID datafor each device or control unit attached to native FICON channels and display the RNID data using an operatorcommand. In z/OS, the output of the DISPLAY MATRIX operator command (D M=DEV) includes RNIDs to helpmake it easier to diagnose these problems by making additional information, such as a devices serial number,available.RNID is exclusive to the z9, and is supported by the FICON Express2 and FICON Express features (CHPIDtype FC), and by z/OS.Up to 60 Logical Partitions: IBM is once again doubling the number of Logical Partitions (LPARs). You now havethe ability to define up to 60 LPARs, 15 LPARs per Logical Channel Subsystem, which may provide you evenmore flexibility to allocate hardware resources. With Processor Resource/Systems Manager (PR/SM) andMultiple Image Facility (MIF) you can share ESCON and FICON channels, ISC-3s, and OSA ports across LPARs.Support for up to 30 LPARs became available October 2003.Support of up to 60 LPARs is exclusive to the z9 EC server and is supported by z/OS, z/VM, z/VSE (TM), TPF,z/TPF, and Linux on System z9.OSA-Express2 OSN - Open Systems Adapter for NCP: The OSA-Express2 Gigabit Ethernet and1000BASE-T Ethernet features (#3364, #3365, #3366) now have the capability to provide channelconnectivity from System z9 operating systems to IBM Communication Controller for Linux on zSeries (CCL)with the introduction of the Open Systems Adapter for the Network Control Program (OSA for NCP)supporting the Channel Data Link Control (CDLC) protocol, providing an alternative to a SNA network.

A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 27 of 82OSA-Express2 OSN can help to eliminate the requirement to have any form of external medium (and allrelated hardware) for communications between the host operating system and the CCL image. Traffic betweenthe two images (operating system and CCL) is no longer required to flow on an external Local Area Network(LAN) or ESCON channel; traffic can flow LPAR-to-LPAR. OSA-Express2 OSN provides an efficient method ofcommunication, and is designed to create a secure and seamless integration of the host operating system andCCL.If you continue to require SNA solutions that require NCP functions, you can now consider CCL as a migrationstrategy to replace your IBM Communications Controllers (374x). The CDLC connectivity option enables TPFenvironments to now exploit CCL.The OSA-Express2 Gigabit Ethernet and 1000BASE-T Ethernet features provide connectivity with a newCHPID type OSN (Open Systems Adapter for NCP). Each host operating system that currently supports CDLCis expected to be able to utilize CDLC to CCL without changes to the operating system. OSA-Express2 OSNsupports both SNA PU Type 5 and PU Type 2.1 channel connectivity.Utilizing existing SNA support (multiple transmission groups), OSA-Express2 OSN support permits multipleconnections between the same CCL image and the same host operating system (such as z/OS or TPF) image.The operating systems must reside within the same physical server (CPC) as the CCL image.OSA-Express2 OSN:• Is designed to appear to the operating systems as an ESCON channel connected to a 374x device typewhich exploits existing CDLC protocols• Allows system administrators of the various operating systems to configure, manage, and operate theirCCL NCPs as if they were running in an ESCON-attached 374x Communications Controller• Enables NCP channel-related functions such as loading and dumping of the NCP• Does not require external hardware (cables or switches)• Allows multiple CCL images to communicate with multiple operating system images, supporting up to 180connections (374x subchannels) per CHPID type OSN• Can span Logical Channel SubsystemsThe CCL image connects to OSA-Express2 OSN using extensions to the QDIO architecture. Linux support is inthe QETH module.OSA-Express2 OSN support is exclusive to the z9, to the OSA-Express2 Gigabit Ethernet SX, GigabitEthernet LX, and 1000BASE-T Ethernet features (#3364, #3365, #3366), and requires the port to beconfigured as CHPID type OSN, which can be configured on a port-by-port basis. OSA-Express2 OSN isexclusively for internal communication, LPAR-to-LPAR. Concurrent LIC update is supported. OSA-Express2OSN is supported by z/OS, z/VM, z/VSE, TPF, and Linux on System z9. Refer to the Software requirementssection. Refer to the Statement of General Direction section for information on IBM Communication Controllerfor Linux on zSeries support of OSA-Express2 OSN.Improved FICON error recovery: System z9 and z/OS and z/OS.e V1.7 I/O recovery processingimprovements are designed to allow for the system to detect switch/director fabric problems that may causeFICON links to fail and recover multiple times in a short period of time.This enhancement is designed to allow the system to detect these conditions and keep an affected path offlineuntil an operator action is taken. This is expected to help limit the performance impacts of switch/directorfabric problems. The improved FICON error recovery function is available on z/OS V1.4 with the z/OS V1.4z990 Exploitation Support feature (or z/OS.e V1.4 with the z/OS.e V1.4 z990 Coexistence Update feature)with PTFs.

Note that for z/OS and z/OS.e V1.8,which are planned to be available September 2006, the web deliverable and PTFs from the BCPZIIP PSP bucketare not needed. (zIIP PTFs will be included in the BCP subset for z/OS V1R8).There are updates to Omegamon products for zIIP support targeted for general availability. Refer to thezIIP PSP bucket for APAR information.1. OMEGAMON XE on z/OS2. OMEGAMON II for MVS v550 *3. OMEGAMON Base v550 (component of the above products)4. OMEGAMON XE for DB2 Performance Expert on z/OS v3105. OMEGAMON XE for DB2 Performance Monitor on z/OS v310* OMEGAMON II for MVS is a component product of OMEGAMON XE on z/OS, but also a product in its ownright. It also contains within it the product called OMEGAMON for MVS (which customers often refer to as"OMEGAMON Classic").You must also contact your vendors regarding zIIP support. The FMID for the web downloads changes thez/OS release to 1.7.1 for z/OS 1.7 and z/OS 1.6.1 for z/OS 1.6. Check with your ISVs to ensure this will notbe a problem.It is possible to estimate the potential amount of DRDA work which can be redirected to a zIIP prior toinstalling the required hardware and software. IBM has developed tools which can process RMF and DB2 datato provide this information. In order to do this analysis, please have your IBM account team make a request toIBM Techline for a zIIP estimation analysis. IBM Techline will provide a data collection guide as well as anoptional DB2 data reduction tool. The data collection guide asks several questions to allow IBM to do theproper evaluation. Return the completed data collection guide as well as FTP the required RMF data andoptional DB2 data created by the DB2 data reduction program to IBM. The data will be analyzed and a reportsent to your IBM account team.Once the proper level of software is installed on the customer machine, RMF and DB2PM will provide additionalinformation which will show the potential for redirecting work to a zIIP. By using the new PROJECTCPU optionin SYS1.PARMLIB member IEAOPTxx, this analysis can be done prior to installation of the actual zIIPhardware.Special note on TCP Segmentation Off-load feature (also called OSA Large Send): The TCP SegmentationOff-load feature is enabled by default if all of the requirements documented in PK02490 are met. Due to thepotential for OSAs that are using this feature to experience unrecoverable INOPs (requiring intervention byconfiguring the affected CHPIDs off-line), it is currently recommended that Segmentation Off-load bedisabled. To disable Segmentation Offload, it is recommended that the following maintenance be applied andthen code NOSEGMENTATIONOFFLoad on the GLOBALCONFIG statement in the TCPIP PROFILE. Once all ofthe microcode issues for Segmentation Offload are resolved, a Washington Systems Center Flash will bereleased advising what the minimum recommended code level will be. Flash 1232599 on the z/OSCommunications Server Support web page will also be updated at that time. Go to URLhttp://www.ibm.com/software/network/commserver/zos/support/ to subscribe to this (and other) updates.APAR/PTF updates were added to 2094DEVICE and 2096DEVICE PSP buckets in the R8, R7 and R6 sections todisable Segmentation Off-load (OSA Large Send.)

Two subchannel sets are now available per LCSS and are designed to enable a total of 63.75Ksubchannels in set-0 and the addition of 64K-1 subchannels in set-1.With the multiple subchannel set facility, one or two sets of subchannels may be configured to each LCSSwhere subchannel set 0 (zero) may have from 1 to 63.75K subchannels defined, and subchannel set 1 (one) mayhave from 1 to (64K-1) subchannels defined. z/OS will allow Parallel Access Volume Alias (PAV-alias) devices inthe subchannel set 1 (one). MSS is designed to provide greater I/O device configuration capabilities for largeenterprises.z/OS V1.7 supports the use of a second subchannel set for defining Parallel Access Volumes (PAV) aliases onthe z9 EC and z9 BC servers, which provides an additional 64K subchannels. Moving PAV alias definitions to asecond subchannel set can allow more devices to be defined. This new function provides relief from the 64Kdevice limit by allowing PAV aliases to be defined without making device numbers unavailable for definingadditional devices. EREP support is also provided to include the subchannel number for PAV alias devices.MSS is exclusive to the z9 EC and z9 BC servers, and is supported by ESCON (CHPID type CNC), by all of theFICON features supported on the z9 (CHPID type FC), by z/OS, z/OS.e, and Linux on System z9.Wild branch diagnosis improvement: A new hardware function stores the address of the last successfulbranch instruction on the z9. z/OS (and z/OS.e) V1.7 is designed to include this information in dumps, whichcan make it easier to find a program that branches to an unexpected location. This can help decrease problemdetermination time, improve the quality of failure diagnosis, and enhance the probability of first failure faultisolation.

In z/OS (and z/OS.e) V1.7, improved support is provided forCPU activity and system address space analysis.FICON link incident reporting is designed to allow an operating system image (without operator intervention)to register for link incident reports improving the ability to capture data for link error analysis. z/OS willdisplay this information on consoles and will also save it in the system log and in LOGREC.FICON link incident reporting is exclusive to the z9, and is supported by the FICON Express2 and FICONExpress features (CHPID type FC), and by z/OS (and z/OS.e).VLAN management enhancement - support of GVRP for ease of use and simplified management: The OSA-Express2 features now support VLAN prioritization (a component of the IEEE 802.1 standard) to extendsupport of VLANs to help simplify networking administration and management of VLANs. You may no longer berequired to manually enter VLAN IDs at the switch.Generic Attribute Registration Protocol (GARP) Virtual Local Area Network (VLAN) Registration Protocol, alsoreferred to as GARP VLAN Registration Protocol (GVRP), is an application defined in the IEEE 802.1 standardthat allows for the control of IEEE 802.1Q VLANs.OSA communicates with GVRP-capable (IEEE 802.1Q) switches, registering its VLANs and dynamically updatingits table as the VLANs change. VLANs are designed to ease the administration of logical groups of users - theycan communicate as if they were on the same LAN. Traffic can be organized by traffic patterns (such asTELNET, FTP, banking transactions) rather than by physical location.Support of GVRP is exclusive to the z9, is applicable to all of the OSA-Express2 features when in QDIO mode(CHPID type OSD), and is supported by z/OS, z/OS.e, and z/VM. Refer to Software requirements section.HiperSockets supports IP version 6: Internet Protocol Version 6 (IPv6) support is now being offered forHiperSockets (CHPID type IQD). IPv6 is the protocol designed by the Internet Engineering Task Force (IETF)to replace Internet Protocol Version 4 (IPv4) to help satisfy the demand for additional IP addresses.IPv6 was introduced to expand the IP address space from 32 bits to 128 bits to enable a greater number ofunique IP addresses in support of the proliferation of devices now connecting to the Internet, such as cellphones and PDAs.This enhancement allows IPv6 communications between LPARs for z/OS TCP/IP stacks and Linux for zSeriesTCP/IP stacks. It also expands IPv6 connectivity options between TCP/IP stacks in a sysplex whenDYNAMICXCF is configured.The support of IPv6 on HiperSockets (CHPID type IQD) is exclusive to the z9, and is supported by z/OS,z/OS.e, and z/VM.C/C++ ARCH(7) and TUNE(7) options: The ARCHITECTURE C/C++ compiler option selects the minimum levelof machine architecture on which your program will run. Note that certain features provided by the compilerrequire a minimum architecture level. ARCH(7) exploits instructions available on the z9 EC and z9 BC servers.The TUNE compiler option allows you to optimize your application for a specific machine architecture withinthe constraints imposed by the ARCHITECTURE option. The TUNE level must not be lower than the setting inthe ARCHITECTURE option. For more information on the ARCHITECTURE and TUNE compiler options refer tothe z/OS XL C/C++ User’s Guide.

  • 40. A z/OS System Programmer’s Guide to Migrating to a New IBM System z9 EC or z9 BC ServerFebruary, 2007 © 2007 IBM Corporation Page 40 of 82If you are skipping generations of processor hardware during your migration to the System z9 processor, thenyou should go to the PSP Buckets for those generations to ensure that you have all the software requirementsinstalled prior to IPLing z/OS or z/OS.e on the System z9. For example, if you are migrating from a 31-bit-onlyprocessor (e.g., 9672 Rx6) to a System z9 BC, then refer to the z900/z800 PSP Bucket (either 2064DEVICEor 2066DEVICE) for the minimum z/OS and z/OS.e requirements to operate in a 64-bit environment, thenrefer to the z990/z890 PSP Bucket (either 2084DEVICE or 2086DEVICE) for required software support atthat level and finally refer to the z9 BC PSP Bucket (2096DEVICE) for the unique z9 BC requirements.Note: If you are migrating from an old driver level on a z900, z800, z990, or z890 server to System z9, thenyou may want to refer to the PSP Bucket for that server to ensure that you have the highest level softwaresupport required for that level server.The hardware buckets (2094DEVICE and 2096DEVICE) are structured to separate the minimum supportrequired from support needed to exploit specific functions. To simplify finding the appropriate PSP Buckets,and then identifying which PTFs listed in the PSP bucket need to be installed on your system, you can usethe Technical Help Database for Mainframe Preventive Service Planning Buckets(http://www14.software.ibm.com/webapp/set2/psp/srchBroker) and the Enhanced PSP Tool . The web siteprovides a search capability, as well as pull down lists for types of PSP Buckets. The types currently supportedinclude Processors, z/OS, and Functions. So you can simply select the processor you are preparing for and click‘Go’. zAAPs and zIIPs are defined as Functions, so identifying PTFs needed to use (exploit) those functions, isjust as easy. Just scroll down to the ‘Find the bucket by Type, Category, and Release’ heading, selectFunction for the Type field, select either ‘ZAAP’ or ZIIP for the Category field, and click Go.Using the Enhanced PSP Tool will simplify the identification of required service for your specific environment.The tool output presents ‘extract files’. ‘Extract’ files are simply structured lists that identify every PTFfrom the PSP bucket, for every applicable z/OS release. This output can then be processed by the EnhancedPSP Tool (ePSPt) compare program (also downloadable from that same web site). The compare program willcompare the structured list (‘extract’ file) to an SMP/E target zone, and identify any uninstalled service(filtering out service for releases that you don’t have installed). It even will identify if any service has to beRECEIVEd. You can then use SMP/E’s RECEIVE ORDER function (or your favorite service acquisition tool) toobtain the missing service. If desired, you can concatenate several extract files as input to the compareprogram. For example, you could concatenate the extract files for z990, z9 EC, ICSF, and zIIP; and thencompare them to you z/OS V1.6 system to identify ALL PTFs needed for your upgrade in one fell swoop.PSP Bucket Reference TableUpgrade Subset Description2094DEVICE 2094/ZOS2094Z/VM2094VSE/ESAz9 Enterprise Class2096DEVICE 2096/ZOS2096Z/VM2096VSE/ESAz9 Business Class2084DEVICE 2086/ZOS2086Z/VM2086VSE/ESAz9902086DEVICE 2086/ZOS2086Z/VM2086VSE/ESAz890ZOSV1R8 BCPICSF7731(includes zIIP)ICSF

If you are migrating to a z9 from a z990 or z890 (and have performed themigration actions associated with z990 or z890), then you have fewer migration actions than those that arecoming from servers older than z990 or z890 and have not yet performed the migration actions associatedwith z990 or z890.It is important to note that you can migrate directly to z9 EC or z9 BC without going through to intermediateservers, but you still do need to ensure that any migration considerations are satisfied for those servers thatyou "skipped".Detailed information on ALL the “inherited” migration considerations is documented in z/OS Migration. These“inherited” migration considerations include:• Use of z/OS features, web deliverables, as well as PTFs to provide z990 (or z890) (and coexistencesupport).

This new IODF level reduces the size of the IODF andimproves the processing performance of large configurations.To read from, IPL with, and dynamically activate an IODF at the V5 level, the PTFs for coexistence APARsOA07875 and OA08197 are required on back-level systems. If you attempt to IPL with a V5 IODF from aback-level z/OS system that does not have the PTF for APAR OA08197 installed, a wait state occurs. Thecoexistence PTF for APAR OA07875 allows you to view and dynamically activate the V5 IODF, but does notallow you to update the V5 IODF from back-level systems. Once the IODF has been upgraded to V5, the z/OSV1.7 HCD libraries must be used to process updates to it. (A STEPLIB or JOBLIB from a back-level system tothe z/OS V1.7 HCD libraries, or to a copy of the libraries, is acceptable.)Note: APAR OA07875 is available for z/OS V1.4 systems that have the z/OS V1R4 z990 CompatibilitySupport feature installed (that is, HCD FMID HCS7708). z/OS V1.4 HCD without the z990 CompatibilitySupport feature (that is, HCD FMID HCS6091) does not have an applicable coexistence PTF. (Tip: HCD FMIDHCS7708 shows up as "z/OS V1.4 HCD" on its primary panel and is described as "z/OS V1.4 HCD" in thedocumentation. HCD FMID HCS6091 shows up as "OS/390 Release 9 HCD" on its primary panel.)If you are running z/OS V1.4 without the z990 Compatibility Support feature, an additional coexistence andfallback requirement applies: you cannot read or dynamically activate a V5 IODF from the z/OS V1.4 system.If you want to read or dynamically activate a V5 IODF from the z/OS V1.4 system, install the z/OS V1.4 z990Compatibility Support feature (or its replacement, the z/OS V1.4 z990 Exploitation Support feature,) andinstall the PTF for APAR OA07875.Other methods to satisfy this coexistence requirement are:• Do not share the IODF. Use EXPORT/IMPORT or COPY to create a second IODF.• Delay making IODF updates from the z/OS V1R7 system until all systems are at the level of the z/OSV1.4 z990 Compatibility Support feature (FMID HCS7708) or later.

For instance, support for LPAR ID of greater than 15 (xF) requires at least the z/OS V1.4 z990Exploitation support. The z990 coexistence and migration requirements, including restrictions, are documentedin z/OS Migration.New Migration ConsiderationsThe following changes introduced with z9 servers could affect your environment:• Token ring: The z990 and z890 are the last System z servers to offer token ring adapter features on thehardware management consoles (HMCs), Support Elements (SEs), and Trusted Key Entry (TKE)workstations. Thus: – Token ring is not available as a feature on the z9 HMC. Current HMCs with token ringmay be carried forward to a z9 during an upgrade from a z990 or z900. – Token ring is not available as afeature on the z9 Support Element (SE) or Trusted Key Entry (TKE) workstation. Token ring is not offeredas a feature on the z9 EC or z9 BC and cannot be carried forward to a z9 during an upgrade from a z990 orz900. – The OSA-Express Token Ring feature is not supported on the z9. Token ring is not offered as afeature on the z9 EC or z9 BC and cannot be carried forward to a z9 during an upgrade from a z990 orz900.• HMC: The z990 and z890 are the last System z servers on which the hardware management console (HMC)is open. Starting with the z9 EC, the HMC is for the exclusive use of the HMC application. Customerapplications cannot reside on the HMC. The ESCON Directory and Sysplex Timer applications cannot resideon the HMC. TCP/IP is the only supported communication protocol. The HMC supports z9 ECs and z9 BCs. Itcan also be used to support z990, z890, z900, z800, G5, G6, and Multiprise 3000 servers. They must beupgraded to a new AROM level.• ICB-2s and ISC-3s in compatibility mode: The z990 and z890 are the last System z servers to supportIntegrated Cluster Bus-2 (ICB-2) and InterSystem Channel-3 (ISC-3) compatibility mode links. The z9 ECor z9 BC does not support them. If you have ICB-2 or ISC-3 compatibility mode links defined, convert themto a supported link technology.

Up to a maximum of 32 can be defined per server.• ICBs are used for server-to-server communication over short distances, using 10 meter (33 feet)copper cables, of which 3 meters (10 feet) is used for internal routing and strain relief.o Integrated Cluster Bus-3 (ICB-3) (#0993) supports a link data rate of 1 gigabyte per secondand is used to connect z9s to z900s and z800s up to a maximum of 16 links.o ICB-4 (#3993) supports a link data rate of 2 gigabytes per second and is used to connect z9sto z9s, z990s, and z890s up to a maximum of 16 links.• InterSystem Channel-3s (ISC-3s) (#0217, #0218, #0219) supports a link data rate of 2 gigabits persecond and is used for server-to-server communication at distances up to 10 km (6.2 miles) using 9micron single mode fiber optic cables. ISC-3s are supported exclusively in peer mode (CHPID type CFP).The maximum number of external Coupling links combined (ICs, ICB-3s, ICB-4s, and active ISC-3 links) cannotexceed 64 per server.ICB-2 links no longer supported: ICB-2 links were used to support Parallel Sysplex connectivity between 9672G5 and G6 servers and z990, z900, and z800 servers. ICB-2 links are no longer supported.ISC-3 links in compatibility mode no longer supported: Attachment of ISC-3 links on the z9 EC and z9 BC toHiPerLinks (ISC-2) on G5 and G6 servers is not supported. ISC-3 compatibility mode is not supported on the z9EC or z9 BC (CHPID types CFS and CFR).
