Monitoring Initial Size of Coupling Facility Structures

It was noticed a problem during a Coupling Facility outage when was necessary to move structures from one CF to another CF. The rebuild/recovery process was not completed sucessfully because the INITSIZE of a WMQ Structure was smaller than the req...

zOS CFRM - Structure size change requires access to CSFSERV resources

When Coupling Facility (CF) structures are encrypted, any user executing the IXCMIAPU utility to write or update a CFRM policy currently requires access to CSFSERV resources such as CSFKGN (Key Generate) and CSFKYT (Key Test)—even in scenarios whe...

Implenent allocation strategies for CFRM structures as alternative to the preflist

In the definition of CFRM structures, the preflist statement must be individually coded for each structure. As the environment grows, the number of structures can increase rapidly, making it challenging and error-prone to ensure that the preflist ...

Allow more than 8 coupling facilities to be defined in a CFRM policy structure's PREFLIST

Currently the maximum CFs per each structure's PREFLIST parameter in a CFRM policy is 8. As a large shop we currently have to simultaneously maintain two policies in our production environment (one for prod and one for logical corruption detection...

Allow more than 8 coupling facilities to be defined in a CFRM policy

Currently the maximum CFs per Coupling Facility Resource Management policy is 8. As a large shop we currently have to simultaneously maintain two policies in our production environment (one for prod and one for logical corruption detection/LCD), a...

XCF_CF_STR_MAXSPACE health check update

It would be good to update the XCF_CF_STR_MAXSPACE IBM health check so that it displays the current maximum structure space defined in the policy and the current augmented space allocation, when the check is successful. Currently you only see thes...

XCF_CDS_SPOF Healthcheck

Provide customization to exclude mirrored Logger CDS from the SPOF healthcheck, because mirrored CDS are not a SPOF.

parameter to suppress IXL014I, IXL015I, and IXL016I messages when accessing coupling facility structures.

Having a parameter on the IXL* calls would be nice to be able to suppress the IXL* messages that come out.

Make diagnosing IXC440E easier.

when IXC440E message is received the documentation IXC440E - IBM Documentation is complicated. There are multiple displays required to capture required data: Issue DISPLAY XCF commands to get more information about the stalled group members. Use D...

Override CFRM preference list on the SETXCF START command

Whenever there is the need of reallocating structures over the CFs available on a Sysplex the command SETXCF START,REBUILD,STRNAME is used. This command if used with the option LOC=OTHER will honor the CFRM preference list on the active policy. Th...
