  5. 5. © 2016 IBM Corporation5  What: The ISHELL Mount Table is very difficult to work with, especially for a lot of mounted file systems. – Can’t find values easily, can’t see consolidated the file system name and mountpoint, multiple deep steps to get handy information…  z/OS V2.2 ISPF allows easy viewing/changing of the mount table! – “Twisties” help consolidate similarly named file systems and mount points. – Think: SMP/E FIXCAT Explorer. – A helpful find command! – File systems and mount points are shown together!  How to use: 1. ISPF 3.17, File System -> Mount Table by File System or Mount Table by Mount Point. 2. Expand, collapse, find, modify at will.  Considerations: – Check your PF settings, you’ll want PF11 (right) and PF10 (left) support. – Just try it out, and you’ll never go back to the ISHELL Mount Table. z/OS V2R2 Enhancements ISPF: z/OS UNIX Mounted File Systems

  16. 16. © 2016 IBM Corporation16  What: Modify VLF (without stopping and starting it). The current configuration will be replaced with the newly specified configuration.  Use a health check to see if VLF is trimming recently added objects to make way for new objects. Meaning, MAXVIRT for that class may be too small.  How to use:  MODIFY VLF,REPLACE,NN=xx Or NN=(xx,yy,zz)  IBMVLF,VLF_MAXVIRT check runs by default once an hour at low severity and looks at classes to see if objects are being trimmed sooner than their ALERTAGE, thereby not meeting usage goals for VLF.  You can specify ALERTAGE in COFVLFxx for each class and/or as a parameter for the check. The check parameter overrides a COFVLFxx specification.  Default applies when not specified in either (60 seconds). 0 means no alert.  Check exception means MAXVIRT could be made larger, so the object may not be trimmed that soon. Higher ALERTAGE likely will result in more check exceptions.  Default ALERTAGE on check: no parms, uses COFVLFxx.  Example check override: PARM('ALERTAGE(IRR*,45,CSVLLA,70)') Classes not specified take the default.  Consideration:  Check supports VERBOSE mode, is very handy as each class has: Youngest Trimmed Age, Total Exceptions, when Activated, Minimum Trimmed Age, AlertAge, and MaxVirt values. z/OS V2R1 BCP: Modifying and checking on VLF
  17. 17. © 2016 IBM Corporation17 z/OS V2R1 BCP: Modifying and checking on VLF Verbose NO
  18. 18. © 2016 IBM Corporation18 z/OS V2R1 BCP: Modifying and checking on VLF Verbose YES
  19. 19. © 2016 IBM Corporation19 z/OS V2R1 BCP: Modifying and checking on VLF To add a VLF parmlib member to existing with MODIFY command:
  20. 20. © 2016 IBM Corporation20  What: New subcommands on ftp to make transferring MVS sequential, PDS(E), or GDG(E) generation data sets so easy: mvsput and mvsget  Allocation of the target data set can be done automatically, which avoids having to pre-allocate the dataset and get the attributes wrong.  How to use:  ftp mvsput local_ds remote_ds  ftp mvsget remote_ds local_ds  Does have a (REAllocate option to delete, reallocate target data set.  Consideration:  If target data set is already allocated and (REAllocate isn’t used, command fails.  If command fails, target data set is deleted. Restart is not available. z/OS V2R1 CommServer: ftp mvsput and mvsget
  21. 21. © 2016 IBM Corporation21 z/OS V2R1 CommServer: ftp mvsput and mvsget
  22. 22. © 2016 IBM Corporation22 z/OS V2R1 CommServer: ftp mvsput and mvsget

  25. 25. © 2016 IBM Corporation25  What: An SPE on z/OS V2.1 and V2.2 SDSF (PI43902, and a BCP PPT update in OA48578), you can easily see system information: – SYS - System information – LNK – Link list data sets – LPA – Link pack data sets – APF – APF data sets – PAG – Page data sets – PARM – Parmlib data sets – …and SRCH within the returned data sets for members!  How to use: 1. Set up SDSFAUX address space 2. Start enjoying the new panels. z/OS V2R1 SPE Enhancements SDSF: New system information panels
  26. 26. © 2016 IBM Corporation26  Set up SDSFAUX address space – SDSF server address space continues to be optional (and recommended!) The server must be started to use this new function. – When SDSF server is started, the new SDSFAUX address space is automatically started. – SDSFAUX will automatically stop when SDSF server is stopped. – Only one SDSFAUX per system, and can be used by multiple SDSF servers. – Can start manually with S SDSFAUX (and stop with P SDSFAUX)  Considerations: – Recent APARs PI54862 and PI56151 may help. – APAR= PI54862: ISF452E SDSFAUX COMMUNICATIONS FAILED, RETURN CODE 0X00000008, RC= 0X00360806" RECEIVED WHEN USING NEW SDSF COMMANDS – APAR= PI56151: MESSAGE HSF0067E CSVDYLPA ADD FOR MODULE HSFSRVRM FAILED RC=4 RSN=00000401 DIAG=20004001.AT SDSFAUX STARTUP – Doc for the new function is in SDSF Operation and Customization: – V2.2: SA23-2274-03 – V2.1: SA23-2274-01 z/OS V2R1 SPE Enhancements SDSF: New system information panels
  27. 27. © 2016 IBM Corporation27  How to set up SDSFAUX: 1. Copy the sample SDSFAUX (which is an alias of HSFSRJCL) from SISFJCL to your proclib concat, and call it SDSFAUX. – You can call it something else, but you’d need to update ISFPRMxx to give the name if you didn’t use SDSFAUX. – Check the proc, but you shouldn't need to make any updates. 2. SDSFAUX address space requires that SISFLOAD be in either the system linklist (or be in the STEPLIB or JOBLIB). 3. Set up security for SDSFAUX address space. – SAF SDSF class must be RACLISTed. – Define userid associated with SDSFAUX address space (same as SDSF server is fine). – Add a profile in the STARTED class for SDSFAUX.* (or you can use your existing SDSF*.* which is also fine). 4. Set up security for new panels for users. Plenty o’ profiles to control commands on new panels. z/OS V2R1 SPE Enhancements SDSF: New system information panels

  36. 36. © 2016 IBM Corporation36  What: To use the SETSMF command (prior to V2.1) you had to have specified PROMPT(..) in SMFPRMxx at IPL. However, folks didn’t want to specify PROMPT(..) at IPL. – The SETSMF command is less disruptive than a SET SMF=xx command (which resets the entire parmlib member).  New statement in SMFPRMxx AUTHSETSMF|NOAUTHSETSMF can control whether you want (or don’t want) to be able to use SETSMF after IPL. – By allowing SETSMF when NOPROMPT is specified allows the majority of installations to avoid delays at IPL.  How to use: Specify AUTHSETSMF in SMFPRMxx at IPL. Keep NOPROMPT if you like. – You cannot SETSMF to change AUTHSETSMF!  Considerations: – When AUTHSETSMF is specified, the SETSMF command is authorized, regardless of the specification of PROMPT or NOPROMPT. – When NOAUTHSETSMF is specified, the SETSMF command is not authorized, regardless of the specification of PROMPT or NOPROMPT z/OS V2R1 Enhancements BCP: SETSMF without PROMPT at IPL
  37. 37. © 2016 IBM Corporation37 z/OS R13: D SMF,O then trying to do a SETSMS command with SMFPRMxx NOPROMPT IEE970I explanation: The operator entered a SETSMF command. The SMFPRMxx parmlib member in effect includes the NOPROMPT option, which makes SETSMF an incorrect operator command.
  38. 38. © 2016 IBM Corporation38 z/OS V2.1: Added AUTHSETSMF (keeping NOPROMPT) to SMFPRMxx
  39. 39. © 2016 IBM Corporation39 z/OS V2.1: D SMF,O then doing a SETSMS command with SMFPRMxx AUTHSETSMF and NOPROMPT … SUCCESS!
  40. 40. © 2016 IBM Corporation40 © 2007 IBM Corporation z/OS R13 Little Enhancements JES2: JES2 job step transfers = Sysprog = Sysprog & Users
  41. 41. © 2016 IBM Corporation41 z/OS R13 Enhancements JES2: Job step transfers What:  When trying to shutdown a system, there might a long running job (with multiple steps) which has not completed. It might be holding you up from shutting down the system.  You can have the job end execution at the end of the current step, so that it can be restarted elsewhere on the next step (requeued for execution). How to use: – $E Jxxx STEP[,HOLD] – If you don’t use the optional HOLD, the job will be back waiting to execute, and will resume if the class or initiators are not drained. Considerations:  Job must be restartable (JOURNAL=YES on JOBCLASS)  Full cross member support. To move the job, it must not be eligible to run on original system (alter the affinity, drain job class, service class, or member).  Has no effect of the job is executing its final step.

  46. 46. © 2016 IBM Corporation46 What: Will tell you the description and action text for a reason code for the following functions:  z/OS UNIX System Services, TCP/IP, zFS, TFS, C/C++ Runtime Library, and NFS (as of V2.2!) Can run from TSO or the shell, and even through System REXX as an MVS system command. How to use: The FIXCAT Explorer is found deep in the SMP/E panels:  bpxmtext [-d] reason_code | error_number Example==> bpxmtext 058800B0 Considerations: Doesn’t work for HFS. Older than the hills: z/OS UNIX: bpxmtext
  47. 47. © 2016 IBM Corporation47 Older than the hills: z/OS UNIX: bpxmtext

  50. 50. © 2016 IBM Corporation50 Older than the hills…NOT! z/OS UNIX: bpxmtext IBM Doc Buddy! Another alternate method (and now reason codes are found in the app under z/OS UNIX System Services, just search on reason code)
  51. 51. © 2016 IBM Corporation51 What: Allows you to discover and select SMP/E FIXCATs. This is an excellent way to find new SMP/E FIXCATs that have been added And to make sure that certain interesting FIXCATs are always verified when doing APPLY, ACCEPT, and REPORT MISSINGFIX commands. How to use: The FIXCAT Explorer is found deep in the SMP/E panels:  1.1 -> global -> 2 Options -> select your options -> 7 -> 2 -> YES for explore.  Expand and Collapse, and FIND any FIXCATs you are interested in. Considerations: Your SMP/E table member will remember when you last were there, and show you the new ones since your last visit. Older than the hills: SMP/E: FIXCAT Explorer
  52. 52. © 2016 IBM Corporation52 Older than the hills: SMP/E: FIXCAT Explorer

  56. 56. © 2016 IBM Corporation56 Older than the hills: SMP/E: FIXCAT Explorer Everything selected from the Explorer is now saved for that Options entry. When doing an APPLY, ACCEPT, or a REPORT MISSINGFIX command, that selected FIXCAT will be considered (and doesn’t need to be explicitly specified).
  57. 57. © 2016 IBM Corporation57 Older than the hills: SMP/E: FIXCAT Explorer
  58. 58. © 2016 IBM Corporation58 Older than the hills (z/OS R11, back to R9): BCP: Tape Library Load Balancing What: A new optional algorithm for all non-specific tape requests (i.e.scratch) to be balanced across tape libraries based on the number of devices in the library, all other things being equal.  Otherwise (default) the tape requests are equally random across libraries, and may be “unfair”. How to use: As expected, use SETALLOC and ALLOCxx: 1. SETALLOC SYSTEM,TAPELIB_PREF=BYDEVICES – To revert back: SETALLOC SYSTEM,TAPELIB_PREF=EQUAL 2. To make permenant in ALLOCxx: SYSTEM TAPELIB_PREF(EQUAL|BYDEVICES) 3. D ALLOC,OPTIONS To query current options Considerations:  No prerequisities. All done in Allocation.  BYDEVICES has been found to scale much better than EQUAL for tape devices (virtual or otherwise), even in balanced configuration!  Customers with the newest TS7700’s have gotten good results with it.  This function is even more attractive if you are adding new tape libraries (with lots of devices), and want to reduce a chance of overload onto the older tape libraries (with fewer devices).  Remember to make a dynamic change permanent, to avoid regression.
  59. 59. © 2016 IBM Corporation59 Older than the hills (z/OS R11, back to R9): BCP: Tape Library Load Balancing Example Without Tape Library Load Balancing: TAPELIB_PREF(EQUAL) … 1024 tape devices 8 tape devices Scratch tape request ½ = 50% ½ = 50%Equally likely
  60. 60. © 2016 IBM Corporation60 Older than the hills (z/OS R11, back to R9): BCP: Tape Library Load Balancing Example With Tape Library Load Balancing: TAPELIB_PREF(BYDEVICES) … 1024 tape devices 8 tape devices Scratch tape request 1024 / (1024+8) = 99.2% 128 times more likely 8 / (1024 + 8) = 0.7%
  61. 61. © 2016 IBM Corporation61  What: REXX interface means you can easily write programs to use ftp! – In addition to Java, C, COBOL, PL/I, and assembler.  How to use: – Handy sample is found in TCPIP.SEZAINST(EZAFTPIR) – Understand the FCAI stem variables, which represents an instance of use. – result = ftpapi(stem, request_type, parm1, parm2, ...) 1. ftpapi('fcai.', 'create', mytraceid) create the fcai 2. ftpapi('fcai.', 'init', myserver, myvar1, myvar2) open a connection 3. ftpapi('fcai.', 'scmd', my_subcommand, 'W') do an ftp subcommand 4. ftpapi('fcai.', 'term') terminate the connection, but you should subcommand quit first to get the trace information.  Considerations: Connecting to an ftp server that can accept an anonymous userid is ideal. I had to provide my password “in the REXX”, if not.  Doc: z/OS Communications Server: IP Programmer's Guide and Reference Older than the hills (z/OS R8): Communications Server: REXX ftp client API
