Hello, I ran into this error today, so here is what I did to fix it:
DB02 or DB13 showed Oracle 10.2.0.5 in System Configuration and following popup came up:
Database system was incorrect (should be MSSQL) and also DB host was "old", meaning there was hostname of migration source system.
All I had to do was press Delete button to delete given record and then Add new one. It caused short dump, but after I got back to DB02, everything was ok:
I hope this might help someone in future...
Regards,
Martin
