DFS4338W WAITING TO READ THE IMS DIRECTORY STAGING DATA SET. IT IS EITHER IN USE OR ALREADY ALLOCATED.
Explanation
During the processing of a DDL request or the IMPORT command, IMS was unable to read the staging data set of the IMS directory because it was already allocated or in use by another job.
System action
IMS waits and resumes processing of the DDL request or the IMPORT command when the data set becomes available.
If the contention persists for 150 seconds, IMS issues message DFS4333E and terminates the processing of the DDL request or IMPORT command. Any updates to the IMS catalog that were made during the processing of a DDL request are backed out.
System programmer response
After the contention has been resolved, attempt the process again.
