Joshi, Is your OEM install in the same directory(Oracle Home) as your 9i client? If not, check to make sure that your network/admin/sqlnet.ora, tnsnames.ora files are correct in the Oem Oracle Home. You can also debug this better using tnsping from a dos prompt. Again, make sure that you are running it from the correct Oracle home. It sounds like a simple tns connect issue.

I agree that OEM is avoidable most times. However it is useful at times for some info and screens. So I am still looking for an solution for this strange behaviour.

After entering username password I click on OK but it does not do anything. I can connect from sqlplus. This is XP, oracle 9i, OEM version 9. Can someone help? I installed oracle again but that did not help. Thanks I think you will a lot folks here that eschew the use of OEM, and simply use methods that work. eg. sqlplus -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist ________________________________ Why keep checking for Mail?
