Stopping DS gracefully

Terala · Post by **Terala** » Tue Dec 30, 2008 3:41 pm

I need to recycle DataStage Server but there is one Established connection which I am unable to kill.

bin/uv -admin -info shows no DataStage process
DS-TOOLS shows no locks or active semaphores
ipcs command shows no memory shared segments

But when I execute netstat -an|grep 31538, there is one established connection. I tried to kill it by executing lsof -i tcp:31538 ( got the PID),
tried to kill the PID but still the established connection is there.

what else left? reboot unix?

thanks

You should do "lsof -P |grep 31538" first to get the process ID, then issue the "kill" of that process ID.

What is the state of the connection as shown by netstat -a? On some OS's these hanging connections will timeout automatically after a lengthy period (I think it might be 45 minutes by default on AIX) and on others, notably HP-UX, these sessions will not timeout and a reboot might be the only option.

You should get one process with your netstat query. This is the dsrpcd process - it should be there, with a state of LISTENING. You can shut down gracefully if this is the only process on port 31538.
