This document describes using RMAN's duplicate database feature to restore a database backup across multiple mount points. Specifically, it restores the APPS_TS_MEDIA tablespace datafiles to /u01/app/oradata and all other datafiles to /u02/app/oradata. It provides a RMAN script that allocates channels, sets the new name for APPS_TS_MEDIA, and duplicates the database, distributing the datafiles as specified.

1. Duplicate Database advance Method for distributing datafiles into multiple locations
Nabi Mohammad
We have belowrequirementinone of ourcustomer.
While restoringthe database,we needtodistribute the datafilesintotwomountpoints
1. All APPS_TS_MEDIA tablespace datafiles into /u01/app/oradata
2. Andremainingall into/u02/app/oradata
I have usedduplicate database methodtoperformthe refresh.The above requirementcanbe achieved
as belowwiththe RMAN duplicate script.
Pre- requisitesforthis Method:
- Database versionmustbe 11GR2 or higher.
- db_file_name_convert&log_file_name_convertparametersmustbe setrespectivelyforthe
remainingdatafiles.
-bash-4.1$ cat rman_restore.sh
RMAN AUXILIARY / LOG=restore.log <<EOF
RUN
{
ALLOCATE AUXILIARY CHANNEL C1 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL C2 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL C3 DEVICE TYPE DISK;
SET NEWNAME FOR TABLESPACE APPS_TS_MEDIA to '/u01/app/oradata/%b';
DUPLICATE DATABASE TO <SID> BACKUP LOCATION '<full_path_of_backup_loction>'
NOFILENAMECHECK ;
}
EOF
%b - Specifies the file name stripped of directory paths. For example, if a data file is
named /u02/app/prod/APPS_TS_MEDIA14.dbf,then %b results
APPS_TS_MEDIA14.dbf.
<full_path_of_backup_loction> - Backup path where all the RMAN backup pieces reside
<SID> – Name of the database
