Resolving the problem


1. Increase EXEC REGION in the JCL (Either on the Jobcard or on the individual step)
2. Include DD DCB BLKSIZE (or use smaller BLKSIZE). For example: EBDI016 Split Files should have BLKSIZE 8000 (as delivered) or lower, when using more than a few Split Files. When BLKSIZE is Missing or Zero, IBM uses initial BLKSIZE = 32767. The default BUFNO=10 will allocate 327K for each file.
3. Include EXEC ,PARM='/ALL(ON)' in the JCL. This allows execution above the line.
