Oracle Database Discussions

Newbie here.

So I am starting to use OEM on Windows XP workstation and have upgraded it to 10.2.0.4 and also wanted to upgrade the repository to 10.2.0.4 as well.

So this is what I have done so far.

I have installed 10.2.0.1 into a new home. I have patch it to 10.2.0.4. I am using DBUA to upgrade the database and have set my ORACLE_HOME to the new home and started DBUA. Everything is working just fine until the new OracleService is created and is trying to start. I received a message that it is unable to start service. If i click on continue I received the ORA-12560 TNS error. I have tried multiple times to get this to work and it always fails on this part..

Also to let you know that when I connect to SQLPlus before upgrade I have to connect using sysplus sysman/xxxxx@emrep with out emrep it won't connect. I have also set TNS_ADMIN to the original homes network/admin directory.

I have research the documentation on upgrading, but maybe I am missing a step or someone has run into the same issue.

Any help you can lend me would be appreciated.
