An attempt was made and has failed to serialize the catalog, CNVTCAT or REPRO. The catalog is to be serialized to prevent its update during processing.
The CNVTCAT or REPRO command is ended.
If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL, the SYSOUT output for the job, and all printed output and output data sets related to the problem.
You should restrict access to the catalog during this process and rerun the job.
