It is a TeamSite 7.2 running on Windows 2003 for several months.
around 2/3 weeks ago, we started to having problem in "Administration Console". It just shows lots of java exception error.
we intended to reinstall the "Administration Console" after we can't find solution. But the reinstall was not success and shown an unsuccessful message.
-------------------------------------------------------------------------
The install processing was unsuccessful, xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
------------------------------------------------------------------------
Then we tried to restart the server and reinstall again.
But we can only see the following error message once opened IWOVInstaller-Windows-7.1.0.0.1.exe
-------------------------------------------------------
The upgrade/reinstall processing was unsuccessful.
Unable to Obtain DB Type information from Panels
-------------------------------------------------------
There are many errors in log files such as livesite can't get UserPerference from DB, and our customized Hibernate can't open session.

I guess there is some problem with DB, but i can't find the problem and solution.
Does any one knows something about it? otherwise we have to reinstall teamsite in a new server..

Many Thanks in advance!
