Restore rman backup to different server with different database name

Here we will restore oracle database from backup to another server and do the database clone from rman hot backup.

We have taken "RMAN backup" of PROD and  will  restore rman backup to different server with different database name.

➨ For Multitenant -Backup and Recovery of Container Database (CDB) and Pluggable Database (PDB) you may check at https://sajidoracledba.blogspot.com/2019/09/12c-multitenant-container-and-pluggable-RMAN-Backup.html

Lets take two servers as below:

SERVER1—PROD

SERVER2---TEST

ON SERVER1:


DB Name: PROD

➨Take backup of PROD with archivelog,controlfile and spfile.

RUN

{

    sql 'alter system archive log current';

    BACKUP AS compressed backupset filesperset 8 DATABASE FORMAT '/Backup01/DB_%d_%p_%T_%s.rbkp' TAG DAILY_HOT_BACKUP;

    sql 'alter system archive log current';

    BACKUP AS compressed backupset ARCHIVELOG ALL NOT BACKED UP 1 TIMES FORMAT '/Backup01/ARCBAK_%d_%p_%T_%s.rbkp' TAG ARCHIVE_BKP;

    BACKUP AS compressed backupset CURRENT CONTROLFILE FORMAT '/Backup01/CNT_%d_%p_%T_%s.rbkp' TAG CONTROL_FILE;

    

Backup spfile FORMAT '/Backup01/SPFILE_%d_%p_%T_%s.rbkp'; 

CROSSCHECK COPY;

    CROSSCHECK BACKUP;

    CROSSCHECK ARCHIVELOG ALL;

    DELETE ARCHIVELOG UNTIL TIME 'sysdate-4' BACKED UP 1 TIMES TO DEVICE TYPE DISK;

    DELETE EXPIRED BACKUP;

    DELETE NOPROMPT OBSOLETE;

    DELETE NOPROMPT EXPIRED COPY;

    DELETE NOPROMPT EXPIRED BACKUP;

    DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;

}

➨Copy all backupsets from SERVER1(Location: /data1/bak/TEST/) to SERVER2(Location:/u01/backup/TEST/) , So that we will restore oracle database from cold backup.

ON SERVER2:

–Create pfile for database TEST.


DB Name: TEST

#export ORACLE_SID=TEST
#rman target /

RMAN>startup nomount;
RMAN>restore controlfile from '/u01/backup/backup_db_c-300166359-20120316-00';   --- complete path of backup
RMAN>alter database mount;

➨Since backup location on SERVER2 is different from SERVER1, so we have to use catalog command to update new backup location in controlfile.
Use below command for all backuppieces:

RMAN> CATALOG START WITH '/my/backup/location';

Or

RMAN>catalog backuppiece '/u01/backup/ora_df_020412_21_14_NSNDB_1635_1';
RMAN>catalog backuppiece '/u01/backup/ora_df_020412_21_14_NSNDB_1636_1';
RMAN>catalog backuppiece '/u01/backup/ora_arch_230412_13_43_NSNDB_23_1';
RMAN>catalog backuppiece '/u01/backup/ora_arch_230412_13_43_NSNDB_24_1';

➨ Since datafile location on SERVER2 is different from SERVER1, So we have to update controlfile for same with SET NEWNAME clause:


Now restore database backup on SERVER2:

RMAN>
run
{
set newname for datafile '/data02/oradata/system01.dbf' to '/u01/oradata/nsnbak/system01.dbf';
set newname for datafile '/data02/oradata/undotbs01.dbf' to '/u01/oradata/nsnbak/undotbs1.dbf';
set newname for datafile '/data02/oradata/sysaux01.dbf' to '/u01/oradata/nsnbak/sysaux01.dbf';
set newname for datafile '/data02/oradata/users01.dbf' to '/u01/oradata/nsnbak/users01.dbf';
restore database;
switch datafile all;
}

RMAN>exit;

–Also update redo log file in controlfile on SERVER2:

#sqlplus "/as sysdba"

SQL>alter database rename file '/data02/oradata/redo07.log' to '/u01/oradata/nsnbak/redo07.log';
SQL>alter database rename file '/data02/oradata/redo08.log' to '/u01/oradata/nsnbak/redo08.log';
SQL>alter database rename file '/data02/oradata//redo09.log' to '/u01/oradata/nsnbak/redo09.log';
SQL>exit;

#rman target /

RMAN>
run
{
recover database;
alter database open resetlogs; }

RMAN>exit;

#sqlplus "/as sysdba"

SQL>alter database tempfile '/u01/home/oracle/PROD/tempfiles/temp01_PROD.dbf' drop including datafiles;

sql>ALTER TABLESPACE TEMP ADD TEMPFILE '/u01/oradata/nsnbak/temp01.dbf' size 200m reuse/size 500M;

sql>select name from v$tempfile;

To change DB name follow the below steps:-

To change the database name in addition to the DBID, specify the DBNAME parameter. This example changes the name to test_db:

Ensure that the target database is mounted but not open, and that it was shut down consistently prior to mounting. For example:

SHUTDOWN IMMEDIATE

STARTUP MOUNT

$nid TARGET=SYS/password DBNAME=test_db

SQL>ALTER DATABASE OPEN RESETLOGS;

After that modify the parameter file as db_name
