how to reset default controlfile autobackup device type
Please forgive what I expect is an ultra simple question. I'm a MSSQL DBA needing to administer backups of an Oracle database and thought it'd be best to seek guidance before I really break something 'trying' to fix this issue.
Seems I have managed to change the default device type for controlfile autobackups to the wrong device type and so far, I've been unsuccessful in resetting it to the proper type.
I've tried issuing the configure command with a CLEAR parameter (CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE SBT_TAPE CLEAR;) and the command returns success, but when I do a show of the config, it still indicates the default is sbt_tape.
