ZMEAS Qnnnn 4 digit limit is too small

Trying to use the ZMEAS Qnnnn entry to tune the RTC queue depth. However it only supports 4 digits and we need at least 5 (10000 represents approximately 1 second of RTC activity). I believe the global itself may be a double word.

ZVFAC counters are wrapping too quickly

We are pushing 3-4 million I/Os per second through the VFA subsystem. The real time messages are used on a time initiated basis (58 mins) to align with other displays. The counters used by the ZVFAC entry are wrapping too quickly so we get bad dat...

z/TPF Signal Events can run the system out of resources.

When using the z/TPF Signal Events software the system can run out of SWB resources. The current Signal events don't do enough resource checking while processing the dispatch queue. The use of a dispatch queue, where many small events can be queue...

Logical Record Cache Management (3 of 3) - Need a counter of 'valid entries'

Need a counter of 'valid entries', the current in use counter basically devolves to all the allocated items after a few days (and includes aged-out entries), therefore it provides no useful information. Valid Entries tell me the utilization of the...

Recoverable system heap storage

Need to manage caches like we manage format 2 globals with them coming online at cycle up rather than at the point of first use and being more-or-less ready to go by being pre-populated with saved (e.g. keypointed) data. This is a cache so doesn't...

zREST zDFDL to suport zDFDL expression for the Code Page Encoding Attribute (and DFDL variable for operationId)

z/TPF's zDFDL transformation needs a parameter to specify Code Page of the target transformed object so that EBCDIC 1047, subset of P1024 Terminal Characters in EBCDIC 1047, and UTF-8. This would avoid loading multiple zSwagger Files and zREST Sys...

API Required for Random Number Generation on zTPF

Currently IBM has provided SHA-1 and SHA-256 APIs for use under zTPF. For example, we have tpf_SHA256_digest() function calls. There is now support (via PRNO assembler instruction) on TPF to generate pseudo and true random numbers. We'd like IBM t...
