Reason:
ca1tms
Reason:
The first record in the TMC is not Control Record 1 (TMSCTL#1). This is usually a result of an invalid TMSREMOV operation; information about the error is written to the report created by TMSREMOV. If not the result of a TMSREMOV operation, then it is likely the TMC has been defragmented or moved improperly, or, in new installations, never formatted.
Action:
Verify that the JCL points to the correct TMC. Verify that the TMC has not been destroyed, and that it is properly formatted and resubmit the job.
