function
READ or WRITE
reason
Reason code from the z/OS MVS IXLCACHE request

System action

The system action depends on the function being performed and the reason code from the IXLCACHE request.

If the reason code from the IXLCACHE request is X'0C121052', Db2 might abnormally terminate.

If the reason code from the IXLCACHE request is not X'0C121052', and the function is a WRITE, or a READ performed during rollback or Db2 restart, the page is added to the logical page list (LPL) for the data set and message DSNB250E is issued.

Otherwise, a resource unavailable message is returned to the user with a reason code that identifies the specific problem.

System programmer response

If the problem persists, and the problem affects a single LPAR, restart Db2 on another LPAR.
