ストリームベースのバックアップの RMAN スクリプトの例

Oracle データベースの最適化され、重複排除される、ストリームベースのバックアップを実行する RMAN スクリプトの一部の例を次に示します。

RUN {

# Back up the database.
# Use 4 channels as 4 parallel backup streams.

ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch02 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch03 TYPE 'SBT_TAPE';
SEND ' NB_ORA_SERV=$NB_ORA_SERV';

BACKUP
    $BACKUP_TYPE
    SKIP INACCESSIBLE
    TAG hot_db_bk_level0
    # The following line sets FILESPERSET to 1 and facilitates database deduplication.
    FILESPERSET 1
    FORMAT 'bk_%s_%p_%t'
    DATABASE;
    sql 'alter system archive log current';
RELEASE CHANNEL ch00;
RELEASE CHANNEL ch01;
RELEASE CHANNEL ch02;
RELEASE CHANNEL ch03;


# Back up the archive logs
# The FILESPERSET parameter setting depends on the number of archive logs you have.

ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL ch01 TYPE 'SBT_TAPE';
SEND ' NB_ORA_SERV=$NB_ORA_SERV';
BACKUP
   FILESPERSET 20
   FORMAT 'al_%s_%p_%t'
   ARCHIVELOG ALL DELETE INPUT;
RELEASE CHANNEL ch00;
RELEASE CHANNEL ch01;
#
# Note: During the process of backing up the database, RMAN also backs up the
# control file.  This version of the control file does not contain the
# information about the current backup because "nocatalog" has been specified.
# To include the information about the current backup, the control file should
# be backed up as the last step of the RMAN section.  This step would not be
# necessary if we were using a recovery catalog or auto control file backups.
#
ALLOCATE CHANNEL ch00 TYPE 'SBT_TAPE';
SEND ' NB_ORA_SERV=$NB_ORA_SERV';
BACKUP
    FORMAT 'cntrl_%s_%p_%t'
    CURRENT CONTROLFILE;
RELEASE CHANNEL ch00;
}
