Something has been annoying me and I finally took some time to look it up. It thought I’d spare you all the hassle and share what I found here.
Problem at hand: whenever you start a DCTM job in a repository at a client, it will take 5 to 10 minutes before the job is actually started. That is annoying, especially when you are testing a custom job. I looked around in the usual places, but found nothing. Then I found the following in the DCTM Server Admin guide:
-max_concurrent_jobs argument with the desired value to the agent_exec_method method command line.
