Morning, I was able to get the same admin account that loaded the database on the server. Once log in, I restarted the services, logged in to OEM and started the process again(changing from Non-archive to archive mode). At this point I make the change in OEM to Archive Log Mode to turn on the Archive utility so the rollback segment utility can work proprely. Again, once the database in shutdown and the startup process begins The TNS is not recogized unless the service are turned off and then on again. This just get me back to were I started from. A database in Non-archive mode. Please advise.
