Unanswered: System error from db2start in Windows after installing service pack
Windows 7. DB2 Enterprise Server Edition 10.1. Only one instance. Working yesterday.
This morning, I downloaded and installed Service Pack 4.
I had run db2stop successfully before beginning. Nonetheless, the installer prompted me that there were tasks running, and asked if it should stop them, with the suggestion that I might consider saying "no". But this is a completely private system for testing and I am the only user ... so I said "yes".
The installation completed, but now every time I boot, DB2 is not started. When I try db2start, I get SQL1042C An unexpected system error occurred.
I'll attach the dbdiag.log messages. Any suggestions gratefully received.
