set newname command made easier in 11gR2

From 11gR2 oracle introduced new options for “SET NEWNAME” command.

1.SET NEWNAME FOR DATAFILE and SET NEWNAME FOR TEMPFILE
2.SET NEWNAME FOR TABLESPACE
3.SET NEWNAME FOR DATABASE

The following variables are introduced for SET NEWNAME from 11gR2 :-

%b The file name remains same as the original. For example, if a datafile is named D:\oracle\oradata\matrix\test.dbf, then %b results in test.dbf.
%f Specifies the absolute file number of the datafile for which the new name is generated.
%I Specifies the DBID.
%N Specifies the tablespace name.
%U Specifies the following format: data-D-%d_id-%I_TS-%N_FNO-%f.

Time to test 🙂

In my test, i am creating a duplicate database ORCL, from the rman backup of MATRIX database. As i am doing it on Windows box, i do hit ORA-600 [KSMFPG5], [0xAEC0000], which is a bug, and also mentioned in one of my previous blog.

1. taking backup of matrix database –

RMAN> run{
2> backup database format 'D:\oracle\backup\matrix\%d_%s_%p';
3> backup archivelog all format 'D:\oracle\backup\matrix\arc_%d_%s_%p';
4> }

Starting backup at 11-JAN-12
using channel ORA_DISK_1
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
input datafile file number=00001 name=D:\ORACLE\ORADATA\MATRIX\SYSTEM01.DBF
..............

channel ORA_DISK_1: backup set complete, elapsed time: 00:00:07
Finished backup at 11-JAN-12

The database as well as the archivelog backupset exist in D:\ORACLE\BACKUP\MATRIX\

2. Duplicating db MATRIX to ORCL. Before executing the command, created ORCL pfile , passwordfile and windows service using oradim utility.

For the ORA-600, recreated the controlfile, opened the database using RESETLOGS option and added temp file.

In earlier versions of oracle we had to mention SET NEWNAME command to rename the duplicate datafiles while restoring/duplicating the database, where we mentioned it for each and every datafile.

# set new filenames for the datafiles
SET NEWNAME FOR DATAFILE 1 TO ‘/dup/oracle/oradata/trgt/system01.dbf’;
SET NEWNAME FOR DATAFILE 2 TO ‘/dup/oracle/oradata/trgt/undotbs01.dbf’;

From 11gR2 simply using SET NEWNAME FOR DATABASE has made things easier.
