Cataloging Backup Pieces
It is now possible to manually catalog a backup piece using the CATALOG commands in RMAN. This allows backup files to be moved to alternate locations or manually archived to tape and brought back for restore operations. In Oracle 9i this functionality was only availabale for controlfile copies, archivelog copies and datafile copies. In addition, there are some shortcuts to allow multiple files to be cataloged using a single command. The following examples give the general idea:
# Catalog specific backup piece.
CATALOG BACKUPPIECE '/backup/MYSID/01dmsbj4_1_1.bcp';

# Catalog all files and the contents of directories which
# begin with the pattern "/backup/MYSID/arch".
CATALOG START WITH '/backup/MYSID/arch';

# Catalog all files in the current recovery area.
CATALOG RECOVERY AREA NOPROMPT;

# Catalog all files in the current recovery area.
# This is an exact synonym of the previous command.
CATALOG DB_RECOVERY_FILE_DEST NOPROMPT;
The NOPROMPT clause supresses user confirmation for all matching files.
