DUPLICATE Without Connection to Target Database

Backup-Based: Duplication Without a Target Connection













Oracle DUPLICATE Without Connection to Target Database, that's a 11gR2 Feature. DUPLICATE can be performed without connecting to a target database. This requires connecting to a catalog and auxiliary database.

Start...
- Create password file

$ orapwd file=/oracle/product/11.2.0/dbhome_1/dbs/orapwAUX entries=5

Enter password for SYS:

- Create pfile (use ORACLE_SID=AUX)

SQL> create pfile='/oracle/product/11.2.0/dbhome_1/dbs/initAUX.ora' from spfile;

File created.

Modify initAUX.ora file.

*.audit_file_dest='/oracle/product/admin/AUX/adump'
*.compatible='11.2.0.0.0'

- Check parameters and create some directories

$ mkdir -p /oracle/product/admin/AUX/adump

- Check Target Database in Catalog

$ sqlplus rman/password@catalog
