Refresh TEST/DEV Database from Production RMAN backup

In this post I will explain how to refresh test/dev oracle database from production backup.

For "oracle refresh test database from production" we will prefer from valid production  rman backup.

Here  we have taken valid RMAN backup of PROD and want to restore the backup on TEST/DEV Instance as below. We will ensure the backup of data file, spfile, archive log and control file using rman..

---------------------------------------------------------------------------------

Lets take two servers as below:

SERVER1—PROD

SERVER2---TEST

ON SERVER1:
DB Name: PROD

SQL> select name from v$datafile;

NAME

--------------------------------------------------------------------------------

/data03/PROD/datafiles/system01.dbf

/data03/PROD/datafiles/system02.dbf

/data03/PROD/datafiles/system03.dbf

/data03/PROD/datafiles/system04.dbf

/data03/PROD/datafiles/system05.dbf

/data04/PROD/datafiles/ctxd01.dbf

/data04/PROD/datafiles/owad01.dbf

/data04/PROD/datafiles/a_queue02.dbf

/data04/PROD/datafiles/odm.dbf

/data04/PROD/datafiles/olap.dbf

/data04/PROD/datafiles/sysaux01.dbf

/data04/PROD/datafiles/apps_ts_tools01.dbf

/data04/PROD/datafiles/system122.dbf

/data04/PROD/datafiles/a_txn_data04.dbf

/data04/PROD/datafiles/a_txn_ind06.dbf

/data04/PROD/datafiles/a_ref03.dbf

/data04/PROD/datafiles/a_int02.dbf

/data04/PROD/datafiles/sysaux02.dbf

/data04/PROD/datafiles/olap01.dbf

/data04/PROD/datafiles/a_txn_data05.dbf

/data04/PROD/datafiles/a_txn_data06.dbf

/data04/PROD/datafiles/a_txn_ind07.dbf

–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  ORMAT '/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'; 

};

–Copy all backupsets from SERVER1(Location: /data1/bak/nsndb/) to SERVER2(Location:/u01/backup/nsndb/)

ON SERVER2:

–Create pfile for database nsndb.


DB Name: TEST

#export ORACLE_SID=TEST
#rman target /

RMAN>startup nomount;
RMAN>restore controlfile from '/u01/backup/nsndb/backup_db_c-300166359-20120316-00';
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';

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/nsndb/system01.dbf' to '/u01/oradata/nsnbak/system01.dbf';
set newname for datafile '/data02/oradata/nsndb/undotbs01.dbf' to '/u01/oradata/nsnbak/undotbs1.dbf';
set newname for datafile '/data02/oradata/nsndb/sysaux01.dbf' to '/u01/oradata/nsnbak/sysaux01.dbf';
set newname for datafile '/data02/oradata/nsndb/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/nsndb/redo07.log' to '/u01/oradata/nsnbak/redo07.log';
SQL>alter database rename file '/data02/oradata/nsndb/redo08.log' to '/u01/oradata/nsnbak/redo08.log';
SQL>alter database rename file '/data02/oradata/nsndb/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:

Before executing the nid command, ensure that redolog files and tempfiles renamed accordingly.

SQL>SHUTDOWN IMMEDIATE

SQL>STARTUP MOUNT

$nid TARGET=SYS/<password> DBNAME=test_db

SQL>ALTER DATABASE OPEN RESETLOGS;

After that modify the parameter file as db_name.
