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 and the SYSOUT output for the job.
Change the JCL statement to specify a virtual storage access method (VSAM) data set, or correct the usage of the data set.
