WEBCAST: CBU Enhancements – Feb. 25
ABSTRACT: The CBU for IBM i has been an outstanding success and continues to grow in popularity. In this session we will briefly do an overview of the current
CBU offerings followed by a deeper look into the various aspects of the offering such as entitlement transfers and what you can and can't do with your CBU
environment. We also review IBM i license manager enhancements that, on one hand, block "out of compliance" messages for 520 and 525 users that have
fewer IBM i entitlements than processor activations but, on the other hand, may require special action to transfer entitlements to the equivalently configured CBU
servers. We will leave time for Q and A as well.

An Independent ASP is a method of configuring multiple disk storage
units into one group. The group can be …
Non-switchable
Any or all units in the system tower, except the load source
Any one or more disks anywhere on the system
Switchable
All disk units in a tower other than the system tower
All the units in one tower
A subset of the disk units in a tower
Multiple IASPs in a tower
Disk units from two or more I/O towers
Note: All contents of tower are switched.

IASP HA Solution Considerations
IBM’s HA solutions and technologies for i are continuing to
center around IASPs.
HA system/partition is available while in the “Contingency”
role.
– Is a unique system, not a complete replica of the source system
– Unique instance of i operating system, LPPs, PTFs, etc
– System is available, but IASPs replicated or shared from a
“primary” system are NOT available unless switching or failing
to contingency system.
If using OS or Hardware Based replication of IASP, processes
will need to be in place for synchronizing necessary SYSBAS
objects and settings
May need changes to processes such as change management,
user and security management, system monitoring, etc.

Common Changes and Application
Considerations for IASPs

IBM i Technology Center (iTC)
- 55. IBM i
Typical IASP Migration Project Outline
Determine how IASPs fit into your HA/DR/Server Consolidation/Off-
line backup strategy.
Perform initial proof-of-concept on subset of applications.
Educate administration and programming staff on IASP enablement
considerations.
Set up test environment where application and work management
changes for IASP enablement will be performed and tested.
Devise plan for synchronizing SYSBAS between primary and
secondary systems, if applicable.
Test all process, application and work management changes.
Determine production migration strategy based on available
hardware and replication options.
Test migration process on sandbox environment, if possible
Perform any necessary education to support personnel and users on
process change, etc.
Execute production migration and implement revised HA strategy
based on IASPs, if applicable.

IASP Enablement Considerations
Most changes to support IASPs are typically work-
management oriented. IASP migration can generally be
transparent to most end-users.
Location of application objects
– data, journals, journal receivers
– programs and environment definition objects
– considerations for object types not supported in IASPs
Setup considerations
– Loading of IASPs
Work management considerations
– Name space, library list, job initiation, etc.
Application run time considerations
– Database connectivity – DDM, JDBC, ODBC
– Commitment control scope, join logical files
Additional considerations for multiple IASPs on a system

Location of Application Objects
*SYSBAS ASP Group
Objects not supported in Permanent application data
IASP objects
Exit programs, etc. that Spool files (maybe)
must be found in *SYSBAS
Journals & journal
Operational version of job receivers
control objects (SBSD, etc)
Definitional version of job
Temporary objects control objects (SBSD, etc)
System libraries Application program
objects ?
Application program
objects ?

IBM i Technology Center (iTC)
- 58. IBM i
IASP Set-Up Considerations
Decide whether program objects will be in *SYSBAS or in
IASP
Evaluate IFS directories and files to move to IASP
– Create symbolic links in old *SYSBAS IFS location, pointing to
new location in IASP
Populating IASPs with data
– Use ASPDEV since RSTLIB default will put objects in
*SYSBAS
– Permanent SQL objects cannot span IASP boundaries
– Cannot create files, tables, etc. into QSYS2nnnnn
– Journal objects must be in same ASP group as objects being
journaled
Create new companion libraries for library content to be split
between *SYSBAS and IASP
Modify startup program to vary on IASP
© 2009 IBM Corporation
IBM i Technology Center (iTC)
- 59. IBM i
IASP Work Management Considerations
Determine how application will access specific IASP
(name space):
– Job descriptions INLASPGRP – most transparent to
users
– SETASPGRP
– SQL Connect, etc
Modify JOBDs for USRPRFs
– Set initial ASP Group for user profiles associated with
the application
Library list processing
Evaluate SBSDs for changes or attachment to IASP
– AJEs, PJEs, JOBQs, Routing programs
© 2009 IBM Corporation
IBM i Technology Center (iTC)
- 60. IBM i
IASP Database Considerations
Views, tables cannot span IASP boundary
– No join logicals over physicals in different ASPs or ASP and SYSBAS
Commit block cannot span IASP boundary
– If connected to IASP RDB, cannot commit changes against both IASP and
*SYSBAS (except QTEMP)
Decide on RDB name for IASP
– Single IASP on system, may want to give the old *LOCAL RDB name to the
IASP instead.
DDM files
– Configure to use *RDB for connectivity
New permanent libraries or collections for application:
– CRTLIB LIB(library-name) ASP(*ASPDEV) ASPDEV(asp-device-name)
– Create collection – default for INASP is the current library name space
JDBC, ODBC, FTP connectivity
– Use JOBD of USRPRF to set INLASPGRP where possible

IBM i Technology Center (iTC)
- 61. IBM i
IASP Application Considerations
Switching name spaces (SETASPGRP):
– Typically avoid from within application
– If use, release locks and pointer references first
IASP offline – if program objects remain in SYSBAS:
– Application time out may need to increase for vary on processing
– Application must handle object not available (as result of vary off,
etc.)
Evaluate use of SBMJOB and any commands with ASPDEV
parameter to ensure desired behavior
Can use Vary on/off exit programs for IASP to perform application
startup and shutdown processing

Support for Job Queues in IASP
Job queue object can be created in IASP
– Allows applications to run with IASP with fewer changes
Operationally, identical to JOBQ in SYSBAS:
– User can manipulate jobs (submit, hold, release, etc.) on JOBQ
– User can manipulate JOBQ (clear, hold, release delete, etc.)
Behavioral differences exist:
– Jobs on JOBQ in IASP will not persist across vary off / vary on
– Jobs on JOBQ in IASP will not be available on backup system after
switchover or failover

Quiesce Function
Suspends transactions & operations to ensure that as much in-flight data as
possible is written to disk
– Places transactions at database boundaries if possible
►Use commitment control for maximum effectiveness
Operates against individual IASPs or *SYSBAS
Useful prior to FlashCopy of SYSBAS, FlashCopy of IASP, detaching of mirror
copy, switching of mirror copy

Encryption for ASP
Protects data transmission to and from the disk drive (important in
a SAN environment).
Protects data transmission in the cross site mirroring environment
(only when the data being mirrored is on an encrypted
independent disk pool).
Protects data in the case of theft of the disk drive.
Protects data in the case of return or resale of a disk drive
(reduces the need to sanitize the disk drive).
Must be specified at IASP creation time – cannot be applied to
existing IASPs.

Steps to Enable Oracle’s JD Edwards World A.73 in an
IASP Environment
1) Create the IASP by indicating in iSeries Navigator the
unconfigured disk drives that should be in the IASP.
2) Identify the JD Edwards application libraries to be moved into
the IASP. Eg JDFDATA, JDFOBJ, JDFSRC, CLTCOM, CLTDTA,
CTLSEC. JDFINS library was left in *SYSBAS because it
contains JOBQ objects which weren’t supported in IASPs at
time of publication of article.
3) Move the libraries to the IASP by saving the libraries to tape or
Savefile(*SAVF), deleting them, and restoring them to the IASP
by specifying the ASPDEV parameter on RSTLIB command.
4) Modify the JOBDs that JD Edwards uses to point to the IASP
group created in step 1 eg CHGJOBD
JOBD(<libname>/<jobdname>) INLASPGRP(<IASPname>)
INLLIBL(QGPL, TEMP, rest of libraries)

External Storage Copy Services Network Requirements
IASP based SAN copy solutions
require less network bandwidth than
full system SAN copy
Only IASP data is replicated
► Examples show significant ongoing
network cost savings using IASPs
with asynchronous SAN copy
services
– Previous experience suggests that a 5250 Interactive Application
300Mbs network between sites for
full system replication can be
reduced to 90Mbs by using IASPs
– IASP based cluster solutions provide
the best RTO and RPO, with lower
network costs
