Nobody here knows any of the account passwords for this instance. I want to setup rman backups so they can stop crashing the DB by trying to back it up directly. This instance was installed by a vendor to support their product 'Equity Edge'.

Neither I nor the DBA who was here when I arrived were told this Oracle instance existed. Its on Windows 2000 and I have rebuilt the password file and been added to a group which says I should not need a password to log into Oracle.

Cannot hack SYS, or SYSTEM passwords. Cant connect internal with /nolog.

Not use to Windows environment, could use some help, seems connect internal should work but asks for password and I get a lot of ORA-12560: TNSrotocol adapter errors. tnsnames.ora, listener.ora look fine.

Strange...thanks for any feedback.
