DFS4548ETHE IMS DIRECTORY CANNOT BE UPDATED BY THE CATALOG PURGE UTILITY EXCEPT IN A BATCH JOB.
Explanation
The IMS Catalog Purge utility must update the
IMS directory, but the IMS
system under which the utility is running might also be using the directory without any
serialization with the utility. To prevent conflicts between the online IMS system and the utility, the utility is not permitted to run.
System action
The IMS directory was not updated, and the IMS Catalog Purge utility ended with return code 12.
System programmer response
Run the IMS Catalog Purge utility
as a batch job in a DL/I or DBB region, and ensure that no active IMS systems with ACBMGMT=CATALOG specified in the DFSDFxxx member of the IMS PROCLIB data set are also
running.
