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...

(Dynamic) Recalculation of JQE blocks when SPOOLNUM is increased to avoid increase of BERT resources.

Addition of several new spool volumes to a JES2 MAS unexpectedly increased the usage of BERT resources. In our case, this caused a critical BERT resource shortage. JES2 was last cold started in the year 1997. Therefor the calculated JQE block prob...

Enhance command D XCF,ARMSTATUS to include RESTART_METHOD in use by ARM elements

It would be nice to have the RESTART_METHODs included in the output of display commands "D XCF,ARMSTATUS,DETAIL" and "D XCF,ARMSTATUS,EL=xxxxxxx". The only way to get that information today is by running the IXCMIAPU utility and look at the active...

Need to cater for changing DLIBs when moving from small to larger volumes (catalog entry mismatch)

zOSMF is currently very restrictive and prevents installation to continue if DLIB catalog entries do not match. Especially in our case where we were moving from 3xMOD9 DLIB volumes to one MOD27 for DLIB datasets. This caused the installation to ha...

Initialize DLLs upon program startup

All global variable initialization should happen for all DLL's that are implicitly loaded in an application before 'main' is invoked.

Allow $TDESTDEF,RDEST=USER

Allow RDEST of DESTDEF to be modified dynamically. Currently it requires an all member warm start, which in many environments is just not possible so the change is impossible to make.

Hello Support, Recently we figured out that when mounting an NFS destination from z/OS, we only have the option to use XLAT or not. However, if the mountpoint contains multiple file types (e.g. images and text) we are limited to one option only. W...
