Getting RC=103 when using target-command and having STDIN DD

Post by sctebnt »

I am using the target-command property to have CoZ Launcher run a specific shell script on Linux instead of specifying the commands within the STDIN of the JCL Step.

My JCL still had the STDIN DDNAME and the DD did contain cards. I expected CoZ Launcher to either run both the target-command and STDIN or to only run target-command and ignore STDIN.

However CoZ Launcher instead execute my target-command but set the job step RC to 103, I assume because there were cards found in STDIN.

Is this the expected result? Are there other option to control the actions of CoZ Launcher when both a target-command and STDIN exist?

Code: Select all

What the launcher / and Co:Z Agent (on the target system) does is to run *some* target program. The default is the user's default login shell.

In all cases, DD:STDIN is redirected to the stdin handle of the target program. For a shell, stdin contains the shell script.

It sounds like in your case that the Co:Z Agent is failing because it is trying to pipe DD:STDIN to the target program and the target program is terminating without consuming the datat (signal 13 is SIGPIPE).

That was exactly what was happening, I added some logic to my script to process the STDIN FD and I am now getting my expected results.

Thanks!!
