currently my customer backup is in tape.
They did enable autobackup and they set the controlfile autobackup to a non default format
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'Z:\backup\autobackup\cont
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
unfortunately I have not taken down their dbid.
can restoring tape backup to disk help me to restore spfile since the smallest backup piece is most likely a autocontrolfile backup?
I can just do the following
RESTORE spFILE FROM 'backuppiece full path';
thanks a lot!
