Ok, does your whole system hang or just db2 control center? With DB2 7 there seems to be a problem with opening up pop-up logins. I'm not sure if were experiencing the same problem, just try this, when your db2 control center hangs try clicking inside it, does your system beep?
It's just the DB2 control center which hangs. The task manager shows
it as running. Any other running applications are slowed down during this.
Unfortunately or fortunately the command center is actually running today so I can't run that test.
What I did this morning was to delete and re-create all my data sources. I thought they may have been holding some reference to Version 6. I don't think that's why it's working again. I think this is some conflict be it memory or what.
I took a screen print of all the process's which were running during the time the Control Center was running ok and one when it was hanging.
The difference is a process which is jrew.exe please see below for another posing re this:
