CICS Transaction Server for z/OS

Showing 1327

Quiesce CICS before shutdown

CICS no longer quiesces TCPIPServices as part of SHUTDOWN, which caused a large number of connected clients to terminate when CICS was shutdown. For this RFE we are asking for a more graceful shutdown option.

CICSPlex Global TRANCLASS

We would like to have a the possibility of defining Global Tranclass Resources, and this way to be able to activate them with 'CICS System Group' scope in a CICSPlex.

Update EXCI to set the return code (R15) at termination

EXCI leaves an unpredictable residual value in Register 15 on exit, which defies all expectations and good coding practices. This behavior is documented here: https://www.ibm.com/docs/en/cics-ts/5.5?topic=considerations-setting-return-code-r15-ter...

Create "Balance" algorithm for CPSM routing

This algorithm can be a new algorithm, or an enhancement to the QUEUE algorithm, in which CPU utilization information can be considered. Avoiding disasters in existing algorithms, we prefer that a new one should be created. This feature can be ena...

Reduce CPSM routing heartbeat in normal mode

In CPSM WLM (normal mode), the 15-second heartbeat remains the same for over 10 years. With the improvement of z/OS, CICS, other products and hardware (z15), the 15s value of the heartbeat should be revised, aiming to reduce this time, in a config...

Access Kafka from CICS

Provide access to Kafka from / to CICS.

Improve security processing for TCPIP-services

In a TCPIPService the authentication method must be specified. Currently there is no support for JSON Web Token (JWT).The TCPIPService definition should be enhanced to support at least JWT or better all types of authentication. And the handling sh...

Create a single SMF field that represents the primary wait reason.

There are over 500 fields in the current SMF 110 (1) record. We have started sending these to Splunk, but had to whittle the number of fields down to about 20 considering we process up to 2 billion SMF records per day. There are so many different ...

Interlanguage Calls (ILC) between Java and COBOL, which allow to use the same Working Storage via different ILC calls of one COBOL program

We are modernizing our application and during this process the programs are migrated from COBOL to Java. Because it is not possible to do this in one big step, we do it component by component in many small steps. This requires that ICLs work well....

STGRCVY=NO should work as documented

Why is it useful? Abending the victim task of a storage violation is a defence against applications acting upon and/or committing corrupted data. CICS Documentation (all releases) promises "If you specify STGRCVY(NO), CICS abends the task if it is...
