CHECK(IBMXCF,XCF_CF_STR_SCM_AUGMENTED) found an exception.
A check exception is raised when a coupling facility structure has an in-use augmented space amount greater than its fixed augmented space amount and its in-use in storage-class memory (SCM) structure object counts are zero.
Augmented space is real storage used by the coupling facility as control space to support structure use of SCM. SCM provides relief for temporary CF real storage capacity constraints and additional structure capacity when needed during peak processing periods. Augmented space that is needed to support the use of SCM may be freed when SCM is no longer in use. However, there are cases where it is not possible for the CF to free some (or all) of the augmented space.
A check exception for a structure indicates that it has an in-use augmented space amount greater than its fixed augmented space amount and its in-use SCM structure object counts are zero. The residual use of augmented space is probably largely wasted and precludes coupling facility structure alter processing from dynamically adjusting CF structure storage usage.
Message IXCH0929I in the message buffer lists coupling facility structures allocated with the capability to use SCM, their use of augmented space, and their usage of SCM.
An asterisk (*) before a structure name in message IXCH0929I indicates a structure with residual use of augmented space.
The system continues processing.
Report this problem to the system programmer.
Perform the appropriate rebuild and/or stop duplexing processing to eliminate the residual use of augmented space.
For duplexed structures in which only one structure instance has residual use of augmented space, stop duplexing to keep the structure instance that does not have residual augmented space. Then re-duplex the structure.
For duplexed structures in which both structure instances have residual use of augmented space, stop duplexing to keep the new structure instance. Then rebuild the structure to eliminate the residual use of augmented space. Then re-duplex the structure.
For simplex structures, rebuild coupling facility structures with residual use of augmented space to eliminate the residual use of augmented space.
