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...

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...

Set a Preference List for Monitoring System of a Coupling Facility

We think it is important to set which system will be responsable for monitoring full threshold of a specificCoupling Facility. In environments with GDPS, Ksys should have no product running unless GDPS own, on the recommendationthe GDPS, to not ha...

XCF_CF_STR_NONVOLATILE should have customizable STR-exclusion list

The health check XCF_CF_STR_NONVOLATILE should be customizable in a way that you can specify a list of structure names that should be excluded from the check.

Structure-level control of CF CPU utilization

As discussed in PMR, we had a high consumption problem of a WMQ structure in a CF impacting other users of the CF. Consumption CF reached 90%, and the consumption of structure in question has reached 80% of CF.We need a way to control the use of t...

Possibility to choose the systems to make the XCF Rebuild Copy Process

We think it is important to have the option to choose the systems that will do the system managed rebuild of CF structures by defining a preference list, for example.We had a case where we verified that the system that was doing the copy was a GDP...

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...

XCF CDS defined for a specific system(s)

Submitting a request to have XCF define a generally-applicable interface by which installations could define in the COUPLExx parmlib member what systems they want to use which CDS types. With that interface, we could recognize at add-function time...

Prevent sysplex outage in case of a loss of x-site DASD conn. affecting CFRM CDS's and x-site signaling conn. is maintained

When a system at site 2 first notices a loss of a CDS (primary, since that CDS is usually at site 1), it will broadcast a signal to other systems to initiate removal of the primary. The site 1 systems will dutifully do so but since all connectivit...

SETXCF REALLOCATE with CF storage release delay

SETXCF REALLOCATE processing should be enhanced to handle temporary storage delay when CF performing structure space cleanup.
