Add Heap Memory High Watermarks to default RTMC Dashboards for JVMs

We would like to see the 64-bit and 31-bit high water marks for the heap regions used by JVMs limited by MAXXMES, MAXXMAP, and EMPS. This would be incredibly helpful to monitor Java for any problem troubleshooting, and give us an easier way to fin...

(TPFUG/Visa) - Provide information about loadset resource consumption to warn of possible problems managing very large loadsets

If a loadset contains a very large number of programs, or programs that are very large, activation can result in unexpectedly large increases in CRPA consumption, and loadset accept processing can temporarily consume an unexpectedly large number o...

(TPFUG/Visa) lodic_ext needs CHECKONLY equivalent support

There is no support for c/c++ applications to use LODIC core resource classes that only target specific core block types. As a result we have to either write our own TPFISOC type functions that issue specific LODIC CHECKONLY calls, or use a user L...

Use metadata such as DFDL to generate C structures and assembler DSECTs

With DFDL being both language agnostic and extensible through namespace based attributes and annotations, attributes and/or annotations could be added to indicate the name and optionally, data type, to use when generating such artifacts as well as...

(TPFUG/Visa) Need a mechanism to identify inconsistent views of structure layouts

Consistency of structure definition across all code accessing the structure is critical for correct code. Database corruption or other runtime errors can occur if source component A thinks structure X on file is packed but source component B think...

TPFUG: Provide z/TPF zMQ API that returns the associated Remote or Local zMQ Name(s) for a specified zMQ Dynamic Queue Name

1. It is necessary to be able to enquire on the z/TPF Resources used by zMQQs associated with z/TPF zEVent processing, particularly z/TPF System Work Blocks (zSWB) usage and zMQDepth. 2. For this to be done all local, remote, aliased, dynamic zMQQ...

Use XWBs for MPIF and IPC

In previous exchanges with IBM re: XWB usage, it was noted that MPIF and IPC were not changed via PJ45291 to use XWBs. That being the case, we will not be able to reduce frame usage even after the PJ45291 is applied, which somewhat defeats the pur...

TPF DNS CACCHE TTL and CASTOUT

Currently the ZCACH and ZDTCP DNS entries are deficient in providing the ability to search for a hostname in IDNSHOSTNAME Cache and display it's associated TTL TOD value. Suggest that the "z" entries be enhanced to provide the TTL expiration time ...

Make the TSTB size configurable

We would like to have the option to set the number of tape status table (TSTB) slots to a different value at SIP time. Failing that, we would like to see a larger hardcoded TSTB size. The number of TSTB slots is defined in SIP macro sptabs.mac:&am...

ZMDES DISPLAY full path display needed

ZMDES DISPLAY doesn't always display the full path to files. Comments from the PMR state that file paths are longer than we can fit in the tabular display. Those get shortened. The end of the path is deemed most important, since the assumption is ...
