RMAN CATALOG에서 TARGET DB를 UNREGISTER하는 방법
===============================================
1) UNREGISTER 하고자 하는 Database를 RMAN CATALOG에서 확인한다.
SELECT * FROM RC_DATABASE;
2) UNREGISTER하고자 하는 DATABASE에 속한 BACKUPSET들을 모두 제거한다.
- 제거하고자 하는 BACKUPSET을 알아내는 방법
RMAN> list backupset of database;
- BACKUPSET을 제거하는 방법
RMAN> allocate channel for delete type disk;
RMAN> change backupset XXX delete;
* 위에서는 DISK에대해 CHANNEL을 설정하였지만 TAPE에 대해 CHANNEL설정을
하려면 아래와 같은 COMMAND를 수행한다.
RMAN> allocate channel for delete type 'sbt_tape';
또한 XXX는 'list backupset of database'의 결과 중에서 'LIST OF KEY'의
값을 의미한다.
3) 다음과 같은 PROCEDURE를 RECOVERY CATALOG에서 수행함으로써 DATABASE를 UNREGISTER한다.
execute dbms_rcvcat.unregisterdatabase (db_key, db_id)
* DB_KEY와 DB_ID는 다음과 같은 QUERY문에서 알아낼 수 있다.
SVRMGR> select * from rc_database;
EXAMPLE:
========
Unregistering ORCL database:
1) The following will list the backupset for the database that we want to
uncatlog.
RMAN> list backupset of database;
RMAN-03022: compiling command: list
RMAN-06230: List of Datafile Backups
RMAN-06231: Key File Type LV Completion_time Ckp SCN Ckp Time
RMAN-06232: ------- ---- ------------ -- --------------- ---------
RMAN-06233: 858 1 Full 16-SEP-98 253487 16-SEP-98
RMAN-06233: 858 2 Full 16-SEP-98 253487 16-SEP-98
RMAN-06233: 858 3 Full 16-SEP-98 253487 16-SEP-98
RMAN-06233: 858 4 Full 16-SEP-98 253487 16-SEP-98
==================================
2) The following will show allocation of a delte channel, deleting the
backupset, and running the list command to confirm that the backupsets were
removed. The delete command will remove the backupsets from the backup location.
RMAN> allocate channel for delete type disk;
RMAN-03022: compiling command: allocate
RMAN-03023: executing command: allocate
RMAN-08030: allocated channel: delete
RMAN-08500: channel delete: sid=10 devtype=DISK
RMAN> change backupset 858 delete;
RMAN-03022: compiling command: change
RMAN-03023: executing command: change
RMAN-08073: deleted backup piece
RMAN-08517: backup piece handle=C:\ORANT\DATABASE\RMANORCLBACKUP\DF_344180532_30
_1 recid=27 stamp=344180538
RMAN-03023: executing command: partial resync
RMAN-08003: starting partial resync of recovery catalog
RMAN-08005: partial resync complete
RMAN> list backupset of database;
RMAN-03022: compiling command: list
RMAN-06230: List of Datafile Backups
RMAN-06231: Key File Type LV Completion_time Ckp SCN Ckp Time
RMAN-06232: ------- ---- ------------ -- --------------- ----------
================================
3) From the recovery catalog:
SVRMGR> select * from rc_database;
DB_KEY DBINC_KEY DBID NAMERESETLOGS_ RESETLOGS
584 585 868345165 ORCL 192881 18-AUG-98
1 row selected.
SVRMGR> execute dbms_rcvcat.unregisterdatabase(584,868345165);
Statement processed.
SVRMGR> select * from rc_database;
DB_KEY DBINC_KEY DBID NAME RESETLOGS_ RESETLOGS
0 rows selected.
