Drop Undo Segments - URGENT HELP

755678Jun 24 2010 — edited Jun 25 2010
Hi,

I am currently doing a DR activity.
My database is in version 10.2.0.3.0 and the platform is Windows 2003 server.

When I try to startup my database, the database gets started, but gets crashed immediately after few seconds.
The PMON and DBWR background processes are getting crashed.
ORA-00472: PMON process terminated with error

The alert log gives the below information.
Errors in file d:\oracle\admin\aspplmp1\bdump\aspplmp1_smon_5280.trc:
ORA-00604: error occurred at recursive SQL level 1
ORA-00607: Internal error occurred while making a change to a data block

When I checked metalink, I found a note: 8240762.8, which says that its a bug.
But the workaround they have given is to DROP UNDO SEGMENTS. How do I do that? Could someone please help me out?
OR is there a different way to solve this issue?

Thanks!
