QSH0002 QSHELL Error Message When Calling QSH

From Support

If you have a question or seek clarification, please call Technical Support.

Problem:

I am running a CL program that calls a QSHELL command from batch. I am getting QSH0002 error code 3489 reason code 4.

Solution:

QSHELL message 3489 is ENOSYSRSC. Approximately 95 percent of the time this is caused by trying to run QSH from a subsystem where the subsystem has a only a maximum active job of 1 (one). If you can run the command interactively but not from your CL batch program, it is likely that it is due to the maximum active jobs of the subsystem.

To see the maximum active jobs for a subsystem, on the OS/400 command line type the following (for example, for QBATCH):

DSPSBSD SBSD(QBATCH)

Press the Enter key. Then, select Option 1, Operational attributes. Review and increase the maximum number of active jobs parm if needed.

Also, although spawn() (and, therefore, QSHELL) bypass the job queue, if the maximum jobs are changed, typically the maximum active jobs for a job queue also must be changed. This is displayed under --> 6. Job queue entries.

Since this error message is a result of running out of available jobs. The recommendation is to put this job in its own subsystem or increase the number of jobs allowed to be running in the subsystem.
