DFS5006W IRLM IS NOT ACTIVE AND CATALOG LOCK NOT OBTAINED FOR UPDATES TO DIRECTORY
Explanation
The master IMS system abended during the processing of either an IMPORT DEFN SOURCE(CATALOG) command or DDL statements. This IMS system attempted to take over processing, but could not get a lock on the IMS catalog directory because IRLM was not active. The directory data sets were not cleaned up.
