9i - How to Determine If Oracle Management Server Has Been Configured ?

Question

hi all,
I'm using 9.2 on a Windows 2000 server - but I'm new to this server and don't know what has been done in the past.
I'm getting the VTK-1000 error when I try to connect in Oracle Management Server mode.
To determine the problem, I need to know how I can determine whether the Oracle Management Server has been created/configured. Also, how can I know that the Repository has been created?
This is what I've tried:
-Tried logging in as sysman with a password of oem_temp
- checked the Windows services - none exist as OracleManage... which causes me to think OMS was never configured
But I dont want to destroy something that may already exist. That's why I want to confirm first.
Sorry for the lame question - I'm new to Oracle.
Thanks, John

Well, then you don't have the SYSMAN password. Here you have two options, the first one, is to try to recover that repository or the second option, to get rid of this repository and create a brand new one.
If you are willing to use the existing repository, then you will have to reset sysman's password, the procedure to perform this task is as follows:
Connect by means of SQLPlus to the repository, you should open a session with the OEM repository database owner. In case you don't have this password (most probably) you will have to temporarily reset this password, as outlined on the bottom procedure.
Open a session to the database as the OEM repoistory owner, let's say OEM_REP or whatever is the actual repository.
sqlplus <OEMRepositoryOwner>/<OEMRepositoryOwnerPassword>@<OEMRepository>
At the SQL prompt issue the command:
execute smp_maintenance.reset_sysman();
Your sysman password will be reset to OEM_TEMP, then you can enter if the repository is up and running, and you can issue commands to check status and shutdown it.
Temporarily resetting a db user password:
1. Connect to the database as sysdba:
sqlplus / as sysdba
2. At the sqlplus prompt query the dba_users table to get the password:
select username, password from dba_users where username='<OEMRepositoryOwner>';
Copy the current password in a safe place.
3. Set a new password, let's say 'X'.
Alter user <OEMRepositoryOwner> identified by X;
4. Once you are done with the previous reset sysman procedure, then you can restore the user password:
alter user <OEMRepositoryOwner> identified by values '<PreviouslyEncodedSavedPassword>';
Then you are done.
