After an upgrade, when you try and log into the GUI, you recieve the following error:
java.sql.SQLException: ORA-01403: no data found
This appears to be related to deleting needed roles.
Run awinstall, confirm the settings, enter the Database password, then when it gets to the menu enter:
02 Reapply portions of upgrade ...
03 Set Dba Information
Exit out after this, restart the instance, and you should be able to log in.
