Add a parameter to control the time allowed between IPLs in different CPCs (message ILR031A)

Hello, (We use z/OS 2.5 and GDPS 4.6) We use GDPS to perform DR scenarios. In our DR scenario testing, we've mastered the process and can now perform the whole process in less than 20 minutes. We currently DR the Production systems in 21-22 minute...

Instruction-execution-protection support should be provided for CPOOLs and IARCP64 and IARST64.

For the same reasons support is available in IARV64 and STORAGE OBTAIN/RELEASE: System integrity

Add CSA Information to SMF Record Type 30 Data

Please add SQA/ESQA/CSA/ECSA utilisation data to SMF type 30 records. We often need to understand SQA/ESQA/CSA/ECSA utilisation changes over time but SMF data doesn't provide that level of detail.

z/OS Job/Task Level CSA/ECSA/SQA/ESQA/PVT/EPVT usage

Currently SMF Type30 record does not have any field that shows job or task level CSA, ECSA, SQA, ESQA, Private and e-Private usage. These metrics are only available at LPAR level which is not helpful to trouble shoot or monitoring these metrics. R...

Enhance data returned by IARV64 REQUEST=LIST to improve tracking of memory object creation history.

Shared memory objects are commonly used in system software and can be accessed by multiple system address spaces and components. Diagnosis for memory problems where large shared memory objects are involved would be made easier by enhanced ownershi...
