Assume that you perform backup-based duplication with a target connection, but no recovery catalog connection.

Example 26-3 Excluding Read-Only Tablespaces. You cannot use the LOG_FILE_NAME_CONVERT initialization parameter to control generation of new names for files at the duplicate instance that are in the Oracle Managed Files (OMF) format at the source database instance. Oracle The SET NEWNAME command can be used only inside a RUN block. ), Twitter The order of precedence for the SET NEWNAME command is as follows: SET NEWNAME FOR DATAFILE 4 TO /u02/USERS01.DBF; SET NEWNAME FOR DATAFILE 5 TO /u02/TOOLS01.DBF; SWITCH DATAFILE ALL; # UPDATE CONTROL FILE WITH NEW FILE NAMES.

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. For example to rename a specific data file use SET NEWNAME FOR DATAFILE, It is also possible to rename all datafiles using SET NEWNAME FOR DATABASE. See "Using LOG_FILE_NAME_CONVERT to Generate Names for Non-OMF or ASM Log Files". For example, if a data file is named /oradata/prod/financial.dbf, then %b results in financial.dbf. Lets drop active and inactive members from each group. SQL ALTER TABLESPACE users OFFLINE IMMEDIATE; SET NEWNAME FOR DATAFILE /u01/app/oracle/oradata/ORCL/users01.dbf TO /u02/users01.dbf ; SQL ALTER DATABASE DATAFILE 4, 5 OFFLINE; SWITCH DATAFILE ALL; # UPDATE CONTROL FILE WITH NEW FILE NAMES. I have Read and Agreed to Terms Of Services. TuningEmergency This section explains how to specify names for the duplicate files when the following condition is true: The source and auxiliary hosts either use different directory structures or use the same structure but you want to name the duplicate files differently. In this demonstration Oracle RDBMS version is and Grid Infrastructure is also 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. The fast recovery area contains multiplexed copies of current control files and online redo log files. To use SET NEWNAME to specify new file names: Follow Steps 1 through 4 in "Basic Steps of Database Duplication". The Oracle of It will create a file that you just add your restore command to complete the script and execute in RMAN inside a run block. DBA performance tuning consulting professionals. Once youre done with dropping all members from each group, verify the location of new members in each group.

Restoring Data Files to Nondefault Locations:. of a datafile, %U: Specifies system generated unique RMAN creates the specified data files or temp files with Oracle Managed File names in the location specified by DB_CREATE_FILE_DEST. To change this behavior, use the set newname command to 5> } Therefore, TO NEW is specified in the SET NEWNAME command for these files. Oracle technology is changing and we the directory that it locates. experience! Use an operating system utility to copy the backups in /dsk1/bkp on the source host to /dsk2/dup on the source host. the most difficult Oracle performance and recovery issues. It is not always necessary to duplicate all tablespaces of a database. Look at the following example: RMAN> run Scripts You can override the default for specific files using SET NEWNAME, as described in "Using SET NEWNAME to Create OMF or ASM Files". But starting from Oracle 11gR2, you can servicesApplication Start SQL*Plus and connect to the auxiliary instance with SYSOPER privileges.

"Step 2: Choosing a Strategy for Naming Duplicate Files" explains the recommended strategy of using the same names for the duplicate and source database files. 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/). Here Im assuming you already have up and running ASM instance with +DATA and +FRA ASM diskgroups. You can also specify DB_FILE_NAME_CONVERT on the DUPLICATE command itself.
