The first message in a job log is ‘Job (job name) started on (date) at (time) in subsystem (subsystem name). If (subsystem) name is QINTER it was an interactive job, if QBATCH it was a batch job.
There are always exceptions, but if you have not made any changes to subsystems descriptions, job descriptions, etc., the above should hold true.
Hi..please use this command
Use WRKACTJOB. There is “Type” field. If under Type any
job is showing “INT” = Interactive, ‘BCH” = Batch, “SBS” =
Subsystem, “SYS” = System, “WTR” = Writer (Printer). Batch
job will run in QBATCH Subsystem/Job and Interactive job will
run in QINTER Subsystem/Job.
Batch jobs can be submitted to any subsystem. This can be done via the job description or simply by the submit job request. We have delevopers who occasionally submit batch job to process in QINTER by mistake. It’s actually pretty simple for this ot occur.
