process lm_ip still running after stopping WinCC

[schoenmakers]

Hello,

Just a quick question: When we shutdown WinCC using the kill_pvss2 command, the lm_ip process remains alive. What does it do and is this indeed as intended?

A ps shows:
lofarsys 24986 1 0 Mar07 ? 00:02:39 /opt/WinCC_OA/3.14/bin/lm_ip -a lockmgr -f 600

We are using Linux CentOS7 systems.

Thanks for any clarification!

The lm_ip process is only started once on a system. It is used for the RAIMA database.
When starting the process monitor a check is made if the lm_ip is already running. If it is not running it will be started.
The lm_ip is not stopped when the project and the process monitor is stopped, this is the designed behaviour.

Ok, so that is intended behaviour. I read in an older post that only when you want to start WinCC under a different user account you need to kill this process and start WinCC anew. That behaviour has not changed I guess.

What are the risks of stopping the lm_ip process always when you stop WinCC? We may want to build that into our system, but only if it is harmless to the stability of the system.

Thanks, Arno

you can stop the process after the Project is fully stopped without any risks

Thanks a lot, all the information I needed!
