Greetings,
I find myself puzzled about how RMAN is functioning. I'm running 10gR2
on RHEL3. My backup script does the following (lots of stuff which I
will leave out but is not relevant). The relevant piece is this...
sqlplus -s / << EOF
ALTER DATABASE BACKUP CONTROLFILE TO '<file_spec>';
quit
EOF
$RMAN target / nocatalog <<EOF
RUN {
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK;
BACKUP INCREMENTAL LEVEL=${_BK_LEVEL} FORMAT '<file_spec>'
FILESPERSET=64 AS COMPRESSED BACKUPSET DATABASE;
SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
BACKUP FORMAT '<file_spec>' ARCHIVELOG ALL DELETE INPUT;
BACKUP FORMAT '<file_spec>' CURRENT CONTROLFILE;
RELEASE CHANNEL disk1;
}
EOF
Everything is fine, I have tested restores and all works as expected. My
confusion is regarding the difference between the rman commands...
RMAN> list copy of controlfile;
RMAN> list backup of controlfile;
The copy lists the file created by the...
ALTER DATABASE BACKUP CONTROLFILE TO '<file_spec>';
command and list backup of controlfile displays the file created by
the...
BACKUP FORMAT '<file_spec>' CURRENT CONTROLFILE;
command. I don't understand the difference between the copy and the
backup and how RMAN is tracking and using these two pieces. If anyone
can explain I would appreciate it.
Thanks.
