From the z/OS Unix System Services User's Guide manual on BPXBATCH:
BPXBATCH has logic in it to detect when it is running from a batch job. By default, BPXBATCH sets up the stdin, stdout, and stderr standard streams (files) and then calls the exec callable service to run the requested program. The exec service ends the current job step and creates a new job step to run the target program. Therefore, the target program does not run in the same job step as the BPXBATCH program; it runs in the new job step created by the exec service. In order for BPXBATCH to use the exec service to run the target program, all of the following must be true:
BPXBATCH is the only program running on the job step task level.
The _BPX_BATCH_SPAWN=YES environment variable is not specified.
The STDOUT and STDERR ddnames are not allocated as MVS data sets.
If any of the these conditions is not true, then the target program runs either in the same job step as the BPXBATCH program or in a WLM initiator in the OMVS subsys category. The determination of where to run the target program depends on the environment variable settings specified in the STDENV file and on the attributes of the target program.
In other words, the extra OMVSEX is normal and expected (depending upon your site parameters).
Your JCL works just fine on my site and produces the expected output in STDOUT. Hence, the problem is specific to your site. While it could be RACF, I rather suspect not as you'd get a different error (and no OMVSEX steps) if that were the case. To confirm the lack of RACF problem, try going to ISPF option 3.17 and browse the /tmp/ directory to see if your output and error files are there. If you can see the directory and your files are there, you do not have a RACF problem. If your files are not in the directory, you probably have a permissions problem that your site support group needs to work on (but again, probably not a RACF issue).
STDERR should have the output of your command, if STDOUT does not. You did not post what STDERR printed, thus we on this forum cannot provide much more help.
