RMAN BACKUP BASED DUPLICATION:

High-Level Steps

Creating Directories

Verifying the RMAN backup database with the control file

Creating pfile for clone database

Copying Password file for clone database

copy paste listener and tns for each other: prod & clone

Moving backup files to the directories created for the clone database

Connecting Rman and issue the duplicate command

Target database : TEST 

Cloned database: TESTDB

Verifying the database name, Backups available in RMAN

SQL> select name,open_mode from v$database;

NAME      OPEN_MODE
--------- --------------------
TEST      READ WRITE


RMAN> SHOW CONTROLFILE AUTOBACKUP;

using target database control file instead of recovery catalog
RMAN configuration parameters for database with db_unique_name TEST are:
CONFIGURE CONTROLFILE AUTOBACKUP ON; # default

RMAN> CROSSCHECK BACKUP OF DATABASE;
