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...

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...

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...

Health check MSGBASED

On a GDPS Metro installation there is a GDPS health checker called GDPS_CHECK_XCF that cheks for the XCF CFRM MSGBASED protocol. It raises a high priority alert whenever the LPAR that does the MSGBASED role is a KP system. However when the situati...

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...

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...

IXCMIAPU Should Be Updated to Return The Default Value of Each Structure Attriubte To The CFRM Policy Editor

The CFRM Policy Editor is intended to make it easier and more efficient to manage the CFRM policy. There are many Structure attributes that are assigned default values if the user does not assign a specific value. While those default values are sh...

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...
