The CA Disk utility IXMAINT issues a RESERVE-type enqueue to prevent concurrent updates to the Files Data Set (FDS) so that the integrity of the data set can be maintained. The value of the sysparm IXMQTIME defines how long the RESERVE will be held before it is released to allow other jobs to access the FDS. Setting the sysparm IXMQTIME to zero causes IXMAINT to retain the RESERVE for the entire length of the job. This will prevent other jobs, such as DMSAR Auto-Restores, from being able to access the FDS while the RESERVE is held. Also, if the RESERVE was not converted to a global enqueue, it will prevent jobs on systems other than the one on which the RESERVE was issued from accessing the volume on which the FDS resides. This can suspend any production work attempting to access the volume. This exception will be cleared when this check runs again after the job causing the exception is changed and runs, or after the job statistics are older than the number of days specified in the AGE parameter for this health check. The default value for the sysparm IXMQTIME will be changed to 0300 with the next release of CA Disk.
Set IXMQTIME to 0300 (30 seconds) to allow the needed data sets to be restored in a timely manner. When using a Files Data Set, integrity is maintained using ENQs which can prevent other CA Disk jobs from processing. Because IXMAINT is typically a longer running job, this may delay critically needed data sets from being restored.
