Backup based Cloning a database using RMAN

1)Creating Directories

2)Verifying the RMAN backup database with control file

3)Creating pfile for clone database

4)Copying Password file for clone database

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

6)Moving backup files to the directories which created for clone database

7)Connecting Rman and issue duplicate command

Target database: TEST

Cloned database: TESTDB

STEP – 1

Verifying the database name, Backups available in RMAN(Target Database)

SQL> select name,open_mode from v$database;

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

Verifying the database name, Backups available in RMAN(Target DB)

RMAN> SHOW CONTROLFILE AUTOBACKUP;
using target database control file instead of recovery catalog

Step 2

Creating Pfile for TESTDB (Source DB)

*.audit_file_dest='/u01/app/oracle/admin/testdb/adump'
*.audit_trail='db'
*.compatible='19.0.0'
*.control_files='/u01/app/oracle/oradata/TESTDB/control07.ctl','/u01/app/oracle/oradata/TESTDB/control08.ctl'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=testdbXDB)'
#*.memory_target=1024m
*.nls_language='AMERICAN'
*.nls_territory='AMERICA'
*.open_cursors=300
*.processes=300
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='UNDOTBS1'
#*.db_recovery_file_dest size=2g
#*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'
*.db_file_name_convert='/u01/app/oracle/oradata/TEST/datafile','/u01/app/oracle/oradata/TESTDB'
*.log_file_name_convert='/u01/app/oracle/oracle/oradata/TEST/onlinelog','/u01/app/oracle/oradata/TESTDB'

 

Step 3

Copy target database password file to Source database

[oratest@oracle ~] cp orapwtest orapwtestdb

[oratest@oracle ~] mkdir testdb

Step 4

Copying the RMAN backup pieces and control file auto backup to desired location ‘TESTDB’(source DB)

[oratest@oracle backup]$ cp c-8581000-20210824 /u01/app/oracle/oradata/testdb
