CHECK(IBMXCF,XCF_CF_STR_MAXSCM) found an exception.
A check exception is raised when the sum of the maximum storage-class memory (SCM) for allocated structures exceeds the actual total storage-class memory available to a coupling facility.
Maximum SCM for a structure is the maximum amount of SCM that a coupling facility will allow a structure to use, if needed. SCM for a structure is not pre-assigned, but instead allocated when structure data needs to be migrated to SCM.
A check exception for a coupling facility indicates that the coupling facility's SCM usage allowance for structures exceeds its actual available SCM.
Message IXCH0927I in the message buffer lists coupling facilities in use by the local system that are "over committed" in their maximum storage-class memory assignments to allocated structures.
The system continues processing.
Report this problem to the system programmer.
Determine if too many structures using SCM are mapped to the coupling facility. An over commitment of SCM to structures may result in not enough coupling facility SCM to satisfy structure data migration requests. Inability to migrate structure data can result in structure unavailability conditions.
