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
RMAN configuration parameters for database with db_unique_name TEST are:
CONFIGURE CONTROLFILE AUTOBACKUP ON; # default

RMAN> CROSSCHECK BACKUP OF DATABASE;

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'

#*.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

Check Database Running Parameter

Move the Spfile to Backup File

Restore the spfile from Auto backup Location

Connect rman and Take level 0 backup

Once Level 0 is completed creating a user and table insert the record for the purpose of level 1 Backup

Remove datafiles for testing purposes

Kill the DB instance, if running. You can do shut abort or kill pmon at OS level

Start the DB instance and take it to the Mount stage.

Connect to RMAN and recover the Database

execute the run command mention the level 0 and level 1 TAG

Connect the user and check table rows are recovered, it can be done in level 1 backup

Delete Expired Backups

Check the RMAN configuration and controlfile Auto backup Feature

DELECT CONTROLFILE MANUALY

Keep the Database in NOMOUNT Stage and Restore the control file

Since we are not using an RMAN catalog we need to set the DBID
