The XCMMSGXT exit routine is called before messages are generated on behalf of a resource requester that is in conflict and is waiting for ownership of the target resource. This processing takes place on the same system that the resource requester resides. This exit is called for both conditional and unconditional ENQ conflicts.
The processing in the XCMMSGXT exit routine takes place in the CA MIM address space and is provided data on the conflicting resource name, the resource requester that is in conflict, and the resource owner.
The XCMMSGXT exit routine can influence the conflict message processing for a specific resource requester by setting the appropriate flags in XCMMSGXP parameter list (field MSGX_FLG1). The XCMMSGXT exit routine should pass a return code value of 4 back to its caller when altering the conflict actions.
