If the Oracle User Wizard fails, where I can find the manual script?
You can use the manual script taken from your PC to be run on the server you are connecting to.
The manual script's default location on your PC (to be ran on the monitored server directly) is on your client machine where you have your Spotlight installed under : C:\Program Files\Quest Software\Spotlight\Plug-ins\SoO\OracleScripts
You can copy or ftp that script file to your monitored server and run it there (spool) from SQL Plus (@install.sql).
Once finished then go back to your client machine and use that user you just created with the script (or upgraded), for your new connection in Spotlight's Connection Manager.
