This is a real sticky situation. I was handed over a machine (running an AIX 7.1), and my first task was to re-install DB2 server on it. But someone before me had conveniently removed an instance owner account, and probably recreated it. Now, the problem is this:
1) When I try to uninstall DB2, it says the instance is active and has to be dropped first.
2) When I try to drop this instance, DB2 says there is no such instance.
I am quite new to DB2 administration. Not sure how to proceed here. Any help is appreciated
