IXCH0253E
The CFRM structure event management protocol is inconsistent with the checkowner_or_installation specification.

Explanation

CHECK(IBMXCF,XCF_CFRM_MSGBASED) found an exception.

The CFRM structure event management protocol is evtmgmt in a multisystem-capable sysplex.

In the message text:
evtmgmt
The CFRM structure event management protocol according to the CFRM active policy.
checkowner_or_installation
Resolves to owner or installation to indicate whether the default PARMS from the HZSADDCHECK exit routine are in effect, or user overrides are in effect.

System action

The system continues processing.

Operator response

Report this problem to the system programmer.

System programmer response

If the CFRM structure event management protocol is policy-based, the problem may be that the primary CFRM couple data set was not formatted to support message-based processing, or it may be that a system command was used to switch to policy-based.

IBM® suggests that, when all systems are at z/OS® V1R8 and there is no intention of falling back to a lower level of z/OS, message-based event processing should be enabled because of the large performance, availability, and scalability benefits that it can provide in some parallel sysplex environments.

If the primary CFRM couple data set was not formatted to support message-based processing, bring the required couple data sets into use. The couple data set format utility may be needed to format one or more new couple data sets. One or more SETXCF COUPLE commands can be used to bring the required couple data sets into use. Be sure to update the appropriate COUPLExx parmlib members with the couple data sets in use.

If the CFRM structure event management protocol is policy-based and the primary CFRM couple data set was already formatted to support message-based processing, switch to message-based with the following system command:

  SETXCF START,MSGBASED

If the CFRM structure event management protocol is message-based and policy-based event processing is desired, switch to policy-based with the following system command:

  SETXCF STOP,MSGBASED

Problem determination

The parameters used to format the CFRM couple data sets in use can be obtained with the following system command:

  DISPLAY XCF,COUPLE,TYPE=CFRM

MSGBASED(1) in the message IXC357I response to that command is the indication that a couple data set was formatted to support message-based processing.
