How to report on all on line Informix instances

Hello, I have a test box that is used by many people, they simply login choose a customer and all the needed environment variables are then setup. The user can then bring on line their very own Informix instance for that customer instance. Is there a way i can find out which Informix instances are on line? For example, I have 4GB RAM in the system and I have tuned it to allow 4 instances to run side by side, however people don't shut down their instances when they are finished so I would like to be able to report which instances are on line to warn the user that to many instances are on line and which ones they will need to go and shutdown. Is this possible? Even if I can't report on which instances are on line I at least need to report on how many are in memory at the very least. Thank you in advance.

you can use "onstat -g dis" Print a list of database servers and the status of each.

Hi, we started with 11.10.FC2W1 and with in few months W3 and now on 11.10.FC2W4 and .... proddb:/export/home/informix> onstat - IBM Informix Dynamic Server Version 11.10.FC2W4 -- On-Line -- Up 22:15:04 --10683392 Kbytes But proddb:/export/home/informix> onstat -g dis Server Version: IBM Informix Dynamic Server Version 11.10.FC2W1 any reason why this is not showing 11.10.FC2W4?

Thank you , i didn't realise it was as easy as doing 'onstat -g dis'. I did look but i must have missed it! It works perfectly by the way.
