Get instance names from PIDS?

Posted in 2011

Summary

Malc asked how to find which IDS 9.5 instances were running on HP-UX 11i from PIDs, for an automated shutdown script. Jack Parker suggested onstat -g dis, noting its up/down indicator is not always accurate. Fernando Nunes preferred keeping a config file of all instances and a function to set each environment, check whether it was up and stop it. Malc accepted the onstat tip.

Here's one for you: HP-UX 11i, IDS9.5 Imagine I'm trying to find out which instances are up and running in an automated shutdown script,and I have no prior knowledge of the setup. Although I know where the onconfig files are, I don't know which ones have been started up. I can see there are some instances running using ps -fu informix; I can then find the informix main cpuvp PIDs from ps -ef and looking for the ones with PPID=1; there could be one or several. How can I find the instance names that are running (from that PID info?) so that I can automatically set INFORMIXSERVER to that value and run onmode -yuck? I've looked in /INFORMIXTMP, and all there is in there is several "VP.<instancename>soc.<number>.s" files, some relating to running instances and some not, and they're length 0 anyway. I've looked in ${INFORMIXDIR}/etc/ and the .conf.<instancename> and .infos.<instancename> files don't hold any PID info either. I could look in the message logs and see which instances don't have "Informix Dynamic Server Stopped" at the end, but that's similarly not reliable. ipcs isn't useful either. Any clues?

Although I've noted that the "up" / "down" indicator is not always accurate, and should be taken with a grain of salt. j.

I usually have a config file with all the instances and a function to get all the environments. So if I had to do that I would go through the list, set every environment, check if it was up and stop it. This is useful for a lot of other situations, so I usually wouldn't bother in trying tricks that only solve one issue. Regards.
