Saw this question on BBADMIN-L mailing list which had a useful tip from the community:
Does anyone know if it's possible to run a pushconfig but not start the tomcat processes? I need to do several patches that require a pushconfig but I don't want to wait for the servers to startup and shutdown.
Nick (MSJC): Sure in the pushconfigupdates.bat\sh and pushconfigupdates.bat\sh.bb
files just comment out the line that calls services.start.
Miroslav (CSU Chico): Yes. You just need to comment out the starting part out of the script. We do this regularly after each release pack upgrade. Simply edit pushconfig and comment out the part that tells it to start the app node. We also usually change the text so it says NOT STARTING at the end.
This needs to be an option when upgrading as well. We pretty much never want the system to start up immediately after upgrade finishes.
