Example 26-1 Duplicating with SET NEWNAME FOR DATAFILE

This example illustrates a script that specifies new names for data files 1 through 5 and temp file 1. The script does not set a new name for data file 6 because it is in the TOOLS tablespace, which is excluded from the duplicate database.

RUN
{
SET NEWNAME FOR DATAFILE 1 TO '/oradata1/system01.dbf'; 
SET NEWNAME FOR DATAFILE 2 TO '/oradata2/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/oradata3/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 4 TO '/oradata4/users01.dbf'; 
SET NEWNAME FOR DATAFILE 5 TO '/oradata5/users02.dbf';
SET NEWNAME FOR TEMPFILE 1 TO '/oradatat/temp01.dbf'; 
DUPLICATE TARGET DATABASE TO dupdb
  SKIP TABLESPACE tools
  LOGFILE
     GROUP 1 ('/duplogs/redo01a.log','/duplogs/redo01b.log') SIZE 4M REUSE, 
     GROUP 2 ('/duplogs/redo02a.log', '/duplogs/redo02b.log') SIZE 4M REUSE;
}

Example 26-2 Duplicating with SET NEWNAME FOR DATAFILE and FOR TABLESPACE

This example is a variation of Example 26-1 and uses one SET NEWNAME command to name all data files in the tablespace users. After the example completes, the file names for tablespace users are set to: /oradata4/users01.dbf and /oradata5/users02.dbf.

{
SET NEWNAME FOR TABLESPACE users TO '/oradata%f/%b';
SET NEWNAME FOR DATAFILE 1 TO '/oradata1/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/oradata2/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/oradata3/undotbs01.dbf';
SET NEWNAME FOR TEMPFILE 1 TO '/oradatat/temp01.dbf';
DUPLICATE TARGET DATABASE TO dupdb
SKIP TABLESPACE tools
LOGFILE
   GROUP 1 ('/duplogs/redo01a.log','/duplogs/redo01b.log') SIZE 4M REUSE,
   GROUP 2 ('/duplogs/redo02a.log','/duplogs/redo02b.log') SIZE 4M REUSE;
}

Example 26-3 Duplicating with SET NEWNAME FOR DATABASE

This example is a variation of Example 26-1 and uses a single SET command to name all data files in the database.

RUN
{
SET NEWNAME FOR DATABASE TO '/oradata/%U';
DUPLICATE TARGET DATABASE TO dupdb
  SKIP TABLESPACE tools
  LOGFILE
    GROUP 1 ('/duplogs/redo01a.log','/duplogs/redo01b.log') SIZE 4M REUSE,
    GROUP 2 ('/duplogs/redo02a.log','/duplogs/redo02b.log') SIZE 4M REUSE;
}

The following table shows the results from this example.

Example 26-4 Duplicating a Database from a File System to ASM

In this example, you use active database duplication. If the source database uses a server parameter file (or a backup is available), then you can create a temporary initialization parameter file on the destination host and set only the DB_NAME parameter.

Assume that the source database prod is on host1 and stores its data files in a non-ASM file system. The control files for prod are located in /oracle/oradata/prod/. You want to duplicate the source database to database dupdb on remote host host2. You want to store the duplicate database files in ASM disk group +DISK1.

After connecting RMAN to the target, duplicate, and recovery catalog databases, run the following RMAN script to duplicate the database.

DUPLICATE TARGET DATABASE TO dupdb
FROM ACTIVE DATABASE
SPFILE
PARAMETER_VALUE_CONVERT '/oracle/oradata/prod/', '+DISK1'
SET DB_CREATE_FILE_DEST +DISK1;

When the DUPLICATE command completes, the duplicate database is created, with data files, online redo log files, and control files in ASM disk group +DISK1.

Example 26-5 Duplicating a Database from ASM to ASM

In this example, you use active database duplication. If the source database uses a server parameter file (or a backup is available), then you can create a temporary initialization parameter file on the destination host and set only the DB_NAME parameter.

Assume that the source database prod is on host1 and stores its data files in ASM disk group +DISK1. You want to duplicate the target to database dupdb on remote host host2. You want to store the data files for dupdb in ASM. Specifically, you want to store the data files and control files in disk group +DISK2.

In the DUPLICATE command, set PARAMETER_VALUE_CONVERT to convert all directory locations from +DISK1 to +DISK2. The new file names in +DISK2 are generated by ASM and do not match the original file names in disk group +DISK1.

After connecting to the target, duplicate, and catalog databases, run the following RMAN script to duplicate the database.

DUPLICATE TARGET DATABASE
TO dupdb
FROM ACTIVE DATABASE
SPFILE PARAMETER_VALUE_CONVERT '+DISK1','+DISK2'
SET DB_RECOVERY_FILE_DEST_SIZE='750G';

When the DUPLICATE command completes, the duplicate database is created, with data files, online redo logs, and control files in the larger ASM disk group +DISK2.

Example 26-6 Duplicating with SET NEWNAME FOR DATAFILE and FOR TABLESPACE

This example illustrates a script that specifies literal names for data files 1-5. The only Oracle Managed Files in the source database are the data files in the users tablespace. Therefore, TO NEW is specified in the SET NEWNAME command for these files.

RUN
{
SET NEWNAME FOR TABLESPACE users TO NEW;
SET NEWNAME FOR DATAFILE 3 TO NEW;
SET NEWNAME FOR DATAFILE 1 TO '/oradata1/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/oradata2/sysaux01.dbf';
SET NEWNAME FOR TEMPFILE 1 TO '/oradatat/temp01';
DUPLICATE TARGET DATABASE TO dupdb
  SKIP TABLESPACE tools
  LOGFILE
    GROUP 1 ('/duplogs/redo01a.log','/duplogs/redo01b.log') SIZE 4M REUSE,
    GROUP 2 ('/duplogs/redo02a.log','/duplogs/redo02b.log') SIZE 4M REUSE;
}

Example 26-7 Using SET NEWNAME to Create Files in an ASM Disk Group

This example uses SET NEWNAME to direct individual data files, temp files, or tablespaces to a specified ASM disk group.

RUN
{
SET NEWNAME FOR DATAFILE 1 TO "+DGROUP1";
SET NEWNAME FOR DATAFILE 2 TO "+DGROUP2";
.
.
.
DUPLICATE TARGET DATABASE
TO dupdb
FROM ACTIVE DATABASE
SPFILE SET DB_CREATE_FILE_DEST +DGROUP3;
}
