This scenario assumes that the source database does not currently use a server parameter file or RMAN cannot restore a backup server parameter file. You can use either of the following approaches: Connect RMAN to the source database as TARGET and use the BACKUP command to back up the backups, as explained in "Backing Up RMAN Backups". To perform this operation, your database should be in nomount mode. Oracle forum. First you need access to the last backup or your database. The duplicated subset of tablespaces must be self-contained.

In this demonstration Oracle RDBMS version is 12.1.0.2 and Grid Infrastructure is also 12.1.0.2. The order of precedence means that SET NEWNAME FOR TABLESPACE specifies names for files not named by SET NEWNAME FOR DATAFILE and SET NEWNAME FOR TEMPFILE, whereas SET NEWNAME FOR DATABASE specifies names for files not named by SET NEWNAME FOR TABLESPACE, SET NEWNAME FOR DATAFILE, or SET NEWNAME FOR TEMPFILE. The procedure for creating a duplicate database to an ASM location is similar to the procedure described in "Settings and Restrictions for OMF Initialization Parameters". files. }. When the RESTORE command executes, the users01.dbf data file is restored to /disk2/users01.dbf. Oracle This location is also the default location for Oracle managed control files and online logs if no DB_CREATE_ONLINE_LOG_DEST initialization parameters are specified.

Omitting this parameter enables the database to generate valid Oracle managed file names for the duplicate data files.

The following example uses one SET NEWNAME command to name all data files in the tablespace users. See "Using DB_FILE_NAME_CONVERT to Generate Names for Non-OMF or ASM Data Files". See the following example to understand these substitution Oracle The datafiles are not OMF files and you want to make them OMF. Support. This option is also used with one of the Do not specify LOG_FILE_NAME_CONVERT if you set Oracle Managed Files initialization parameters. This will avoid the manual entry or vi/notepad editing of similar output. The set newname command helps us to restore the database in a different location (/u01/datafile/).
