BCP_Storage Management (inc. RSM/ASM/VSM/DIV)

Showing 15 of 3698

Document usage of DSPSERV macro . . . ORIGIN= parameter.

ORIGIN= is used to support processors that do not support the first 4K block of data spaces. But if the processor is known to support the first 4K, programming for ORIGIN is not needed. If every z/architecture computer supports the first 4K of a d...

For STORAGE RELEASE and FREEMAIN, if conditional, R0 should have a reason code which indicates the cause of the failure. Currently R0 contains no defined values at request completion.

When debugging with conditional STORAGE RELEASE and FREEMAIN, z/OS knows the reason for return code 4, but does not disclose it to the invoker. This makes investigating the cause unnecessarily difficult.

Know how close an AS is to exceeding MEMLIMIT

MEMLIMIT is defined as the limit of private virtual storage that an address space can use above the bar any given time. But, guarded virtual storage and storage obtained with memlimit=no does not count against the MEMLIMIT. In SMF is reported SMF3...

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...

Enable DIAGxx operator command parameter modification function

The ability to be able to issue an Operator command would enable real-time dynamic modification to the individual DIAGxx parameters without the need (or permission/authority) to update a PARMLIB member. This would also enable automation code (Rexx...

TCB field for V64WAENTRY

The 31 bit couterpart VSMLIST has the TCB field IARV64 REQUEST=LIST should have it as well

IARV64 macro to return guard area

We use the IARV64 REQUEST=LIST macro to list all HVCommon memory objects. If you calculate the size of the memory objects using the V64WAEND64 and V64WASTART64 addresses returned from the IARV64 macro, it is possible for those numbers to be off be...
