Sub-Capacity Reporting Tool Recommended Maintenance

For optimal data collection and reporting in a z/OS sub-capacity environment, IBM recommends that you apply PTFs for the following APARs:

• REQUIRED - must be installed prior to data collection on a zEnterprise 196 (2817) or zEnterprise 114 (2818) server
  SMF APAR OA30563 (for z/OS V1.7 through V1.12)
  WLM APAR OA30968 (for z/OS V1.10 through V1.12)
  RMF APAR OA29530 (for z/OS V1.10 through V1.12)
• REQUIRED - must be installed prior to data collection
  WLM APAR OW55509 to allow WLM to calculate rolling 4-hour average utilization data and pass that calculation to a systems management tool, such as RMF, for all native z/OS LPARs. PTFs are available for z/OS Version 1, Releases 1 through 4.
• BCP APAR OA20314 to allow customers who prefer not to change LPAR names to qualify for zNALC to use the "LICENSE=ZNALC" IPL parameter to indicate a zNALC LPAR
• WLM APAR OA02710 to correct the MSU calculations for z890s, z990s and future machines
• WLM APARs OW50998 and OW52306 to correct minor discrepancies between announced and calculated (SRM) machine capacity
• WLM APARs OW49277, OW48894, and OW47277 to improve rolling 4-hour average and softcapping algorithms
• SMF APAR OW50959 & DB2 APAR PQ51040 are used together to reduce the overhead involved in writing SMF89 records from DB2
• SMF APAR OA11036 must be applied before the SMF type 89 records are collected with an LPAR date set to the future or the past
• RMF APAR OA11375 must be applied before the SMF type 70 records are collected with an LPAR date set to the future or the past
• Debug Tool APAR PK30452 (V5) or PK25531 (V6) corrects the SMF89 data reporting problem when Debug Tool product code executes as part of Debug Tool Utilities and Advanced Functions
• IMS APAR PQ46529 corrects a data error when IMS cuts SMF89 records
• WebSphere Application Server for z/OS V5 APARs PQ72892, PQ72893, PQ72894, and PQ67319 (corresponds with Service Level W500002) correct data error when WebSphere cuts SMF89 records
• CMF - If you are using CMF to generate SMF70 records, contact BMC Support (link resides outside of ibm.com) to ensure the correct CMF level/service.

The following APARs do not directly affect SCRT, but you might find them helpful:

• RMF - APAR OW49536 - to correct minor inaccuracies in z/OS V1R1+ RMF Partition Data Report
• RMF - APAR OW49807 - to add new RMF Monitor III function to monitor the current rolling 4-hour average (applies to z/OS V1R2+)
• RMF - APAR OA07203 - to correct various Monitor 3 reporting problems

For optimal data collection and reporting in a z/VSE sub-capacity environment, IBM recommends that you apply PTFs for the following APARs:

• z/VSE V4.1
  • APAR DY47027 – to enable measurements less than 1 MSU
  • APAR DY47152 – to enable support for processing CMT data files using IJBCMTRP that exceed 32767 tracks on ECKD disks
  • APAR DY47110 – required to be installed prior to data collection to enable CMT support on z196 (2817) and z114 (2818) machines
  • APAR DY47196 – to enable extraction of SCRT89 records with DATE or TIME offsets using IJBCMTRP
• z/VSE V4.2
  • APAR DY47029 – to enable measurements less than 1 MSU
  • APAR DY47152 – to enable support for processing CMT data files using IJBCMTRP that exceed 32767 tracks on ECKD disks
  • APAR DY47111 – required to be installed prior to data collection to enable CMT support on z196 (2817) and z114 (2818) machines
  • APAR DY47194 – to enable extraction of SCRT89 records with DATE or TIME offsets using IJBCMTRP
• z/VSE V4.3
  • APAR DY47197 – to enable extraction of SCRT89 records with DATE or TIME offsets using IJBCMTRP

For optimal data collection and reporting in a z/TPF sub-capacity environment please be sure to check the z/TPF Maintenance page for any required service. On that page, select the "XLS" link in the "APAR Data" row of the table, this should launch a spreadsheet. Within the spreadsheet file you may select the “SCRT_APARs” worksheet tab to see the z/TPF APARs which are unique to the sub-capacity environment.

IBM always recommends that you install the most current microcode driver level available. The following microcode patches are available to fix specific problems which affect software pricing, but please be aware that more current microcode levels may be available. Please contact your IBM service representative to coordinate installation of any microcode.

• Update the z990 software pricing MSUs; to allow z/OS WLM to measure rolling 4-hour average in terms of the new z990 software pricing MSUs.
  • Driver 52 - - MCL 058 in the EC Stream J12560
• Correct occasional minor discrepancies between expected and reported capacity in configurations that include ICFs or IFLs.
  • Driver 38 - - MCL 067 in the EC Stream J10003
  • Driver 3C - - MCL 025 in the EC Stream J10637
  • Driver 3G - - fix included in 3G
