If you get the following error when attempting to perform database actions in Oracle 11g Enterprise Manager on Windows XP …
RemoteOperationException: ERROR: Invalid username and/or password
… then, assuming your Username/password combination is correct … and you can verify this by logging into SQLPLUS … follow these steps to resolve:
1. Open Control Panel
2. Administrative Tools -> Local Security Policy (Local Security Setting window opens)
3. Local Policies -> User Rights Assignment
4. Double click ‘Log on as a batch job’ (Properties window opens)
5. Click on ‘Add user or group’ (Select user/group window opens)
6. Add the username(s) including the domain name
7. Click ‘Check names’ to verify what you have added
8. Save (click OK, click OK)
Hope this helps.
