Any ideas???I was attempting to set up an Oracle database backup. The programme (oracle backup) insisted that we have the enteprise manager running. I set the enteprise manager running for sid d1. Various files were created to enable the enteprise manager to run and the system modified the initd1.ora. The test set would not restart at this point. I examinined the initd1.ora and found some corruption in there ( symbols such as you see in a system file) so i renamed the file and reintroduced the original initd1.ora. The sid d1 then restarted. I then ran catrman.sql to create the recovery catalogues. There was some dificulty in connecting to the database but eventually I had backup programme open for D1. There were some problems with accessing the backup program and eneprise dat so I decided to shutdown and restart the d1 database.
Last night I shutdown D1 and it it reported a normal shutdown.....waiting for users to exit. This morning we still had the same message although the users had all logged out. I have tried logging in as internal or as system etc. and tried to open the instance manager or enteprise manager all with the same result. The server will not allow any logons to the d1 database.
logging on as internal - invalid username /password.
logging on as system - oracle unavailable.
none of the oracle gui utilities will access d1 either due to logons or database unavailable.
However , the services are stopping and starting without error in NT
I have tried a full system reboot with no improvement.
