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

    Showing 7

    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.

    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.

    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

    TCB field for V64WAENTRY

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

    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...

    IARV64 LIST service to return storage sensitivity in the returned area mapped by the IAXV64WA dsect.

    This change will can be used for determining which memory objects have been marked 'sensitive'.
