Creating a duplicate database with the DUPLICATE DATABASE command

Expert Oracle Database Tips by Donald BurlesonSeptember 24, 2015

Previously we reviewed the creation of database files at a different location in the auxiliary server by making changes to the parameter file. However this is not the only way to create a duplicate database. The action can be performed directly from RMAN as follows:


  • Use SET NEWNAME command to change location of files of the auxiliary database directly from RMAN

The first way will be explained under this subtopic. The second way will be shown on the next "duplicating database on the local host" subtopic. 

To use the first solution, perform all steps which are mentioned in the beginning of this chapter up to the DUPLICATE command. Change DUPLICATE command and make it as follows:



LOGFILE '/u03/oradata/new_database/redo01.log' size 5m, '/u03/oradata /new_database/redo02.log' size 5m,'/u03/oradata new_database/redo03.log' size 5m;

While running this command, all files will be created on /u03/oradata /new_database directory.
