RMAN Active Duplicate Database in Oracle from ASM to ASM

RMAN Active Duplicate Database in Oracle from ASM to ASM


In a recent article, we demonstrated about Step by Step Migrate Database from Non-ASM to ASM in Oracle click here to know more about it. In this article, we will demonstrate step by step RMAN Active Duplicate Database in Oracle from ASM to ASM with practical.

The active duplicate database features introduced in database version 11g. The Active duplicate database doesn’t require backup. Duplication of database performs over the network copying database files to the auxiliary instance from the live source database which should be either mount or open mode, the preferably open state with zero downtime. Below are the advantages and disadvantages of an active duplicate database.


Advantages

1. Backup is not required of the source database.
2. No downtime require applicable to archive enable on the database.
3. Eliminate manual efforts as post activities.


Disadvantages

1. High utilization of network traffic between Source and Auxiliary Host.
2. It may impact negative performance on the source database throughout entire duplicate activities.

Below are the environment details.

3. Create a PFILE for Auxiliary Instance.

SQL> create pfile='/home/oracle/initlabdb05.ora' from spfile;

File created.


4. Create a password file for Auxiliary Instance if it’s not already available on the Source Database and make sure created with the correct SYS’s password.

[oracle@DBsGuruN4 ~]$ 
[oracle@DBsGuruN4 dbs]$ orapwd file=orapwlabdb05 password=Passw0rd@5743 force=y entries=10
[oracle@DBsGuruN4 dbs]$ ls -lrt orapwlabdb5 
-rw-r----- 1 oracle dba 6144 Aug  14  05:25 orapwlabdb05 


5. Transfer PFILE and PASSWORD files to Auxiliary Host.

[oracle@DBsGuruN4 oracle]$ ls -lrt |tail initlabdb05.ora
-rw-r--r-- 1 oracle dba   1137 Aug  14 02:12 initlabdb05.ora
[oracle@DBsGuruN4 ~]$ scp initlabdb05.ora oracle@DBsGuruN5:/u01/app/oracle/product/12.2.0.1/db_1/dbs/initlabdbdev.ora
initlabdb05.ora                                                                                                        100% 1137   495.9KB/s   00:00
[oracle@DBsGuruN4 oracle]$ cd $ORACLE_HOME/dbs
[oracle@DBsGuruN4 dbs]$ scp orapwlabdb05 oracle@DBsGuruN5:/u01/app/oracle/product/12.2.0.1/db_1/dbs/orapwlabdbdev
orapwlabdb05                                                                                                                100% 3584     1.3MB/s   00:00


Now login to Auxiliary Host and perform the below activities.

6. Validate available free size of destination ASM DISK GROUP/S. Make sure you have enough free space in DG as require to migrate the database. Click here to get the SQL command for How to check ASM diskgroup Size.

7. Create a directory in ASM.

[oracle@DBsGuruN5 ~]$ asmcmd
ASMCMD> cd DATA1/oradata
ASMCMD> mkdir labdbdev
ASMCMD> cd labdbdev
ASMCMD> pwd
+DATA1/oradata/labdbdev

Note: This is a completely optional step instead of it we can use DG +DATA1.


8. Create require Directories for Auxiliary Instance.

[oracle@DBsGuruN5 ~]$ mkdir -p /u01/app/oracle/admin/labdbdev/adump
[oracle@DBsGuruN5 ~]$ mkdir -p /backup/arch/labdbdev
[oracle@DBsGuruN5 ~]$ ls -ld /u01/app/oracle/admin/labdbdev/adump /backup/arch/labdbdev

drwxr-xr-x 2 oracle dba 6 Aug  14 02:48 /backup/arch/labdbdev


9. Prepare PFILE to start Auxiliary Instance. Replace require values according to Auxiliary instance and below two parameters in the same format.


*.db_file_name_convert=’Source Database Datafiles path’,’ Auxiliary Instance Datafiles path’
*.log_file_name_convert= ‘Source Database Redolog File path’,’Auxiliary Instanse Redolog File path’

13. Prepare TNS entries for both Source Database and Auxiliary Instance.

LABDB05 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = DBsGuruN4.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = labdb05)
    )
  )

LABDBDEV =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = DBsGuruN5.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)

Congratulation!!! We have completed successfully restore the database LABDBDEV using Active Duplicate in Oracle. Let’s follow the below steps for post validation on Auxiliary Host.

19. Validate the database size, DBID, creation timestamp, archive enable, etc. Click here to get the SQL command to check the size of DATABASE.

SQL> SELECT BANNER FROM V$VERSION;

BANNER
--------------------------------------------------------------------------------
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
PL/SQL Release 12.2.0.1.0 - Production
CORE    12.2.0.1.0      Production
TNS for Linux: Version 12.2.0.1.0 - Production
NLSRTL Version 12.2.0.1.0 - Production

SQL> SELECT NAME, HOST_NAME, OPEN_MODE, DBID, CREATED FROM V$DATABASE, V$INSTANCE;

NAME      HOST_NAME             OPEN_MODE                  DBID CREATED
--------- --------------------- -------------------- ---------- ---------
LABDB02   DBsGuruN5.com         READ WRITE           3972528048 14-AUG-21


20. Capture all physical files. Click here to get the SQL command for How to find all physicals files in Oracle.

SQL> @Physical_Files.sql

NAME
--------------------------------------------------------------------------------
+DATA1/oradata/labdbdev/control01.ctl
+DATA1/oradata/labdbdev/control02.ctl
+DATA1/oradata/labdbdev/demo2_tbls_01.dbf
+DATA1/oradata/labdbdev/demo1_tbls_01.dbf

+DATA1/oradata/labdbdev/temp01.dbf
+DATA1/oradata/labdbdev/undotbs01.dbf
+DATA1/oradata/labdbdev/users01.dbf

20 rows selected.


21. Validate the path of SPFILE.

SQL> show parameter spfile

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /u01/app/oracle/product/12.2.0.1/db_1/
                                                 dbs/spfilelabdbdev.ora


22. Register database in a server control, applicable here since it’s HAS (ORACLE RESTART).

[oracle@DBsGuruN5 dbs]$ srvctl add database -d labdbdev -n labdbdev  -o /u01/app/oracle/product/12.2.0.1/db_1 -p /u01/app/oracle/product/12.2.0.1/db_1/dbs/spfilelabdbdev.ora -diskgroup DATA1
[oracle@DBsGuruN5 dbs]$ srvctl config database -d labdbdev
Database unique name: labdbdev
Database name: labdbdev
Oracle home: /u01/app/oracle/product/12.2.0.1/db_1
Oracle user: oracle
Spfile: /u01/app/oracle/product/12.2.0.1/db_1/dbs/spfilelabdbdev.ora
Password file:
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Disk Groups: DATA1
Services:
OSDBA group: dba
OSOPER group: dba
Database instance: labdbdev
[oracle@DBsGuruN5 dbs]$


23. Change the value of both convert parameters, SYS password, create PASSWORD file, etc. Again this is an optional step and follows standard requirements.

SQL> alter system reset db_file_name_convert scope = spfile;

System altered.

SQL> alter system reset log_file_name_convert scope=spfile;

System altered.

SQL> shu immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

[oracle@DBsGuruN5 dbs]$ srvctl start database -d labdbdev
[oracle@DBsGuruN5 dbs]$ srvctl status database -d labdbdev
Database is running.
[oracle@DBsGuruN5 dbs]$

SQL> alter user sys identified by Passw0rd@3745;

User altered.

SQL> create pfile from spfile;

File created.

[oracle@DBsGuruN5 dbs]$ orapwd file=orapwlabdbdev password=Passw0rd@3745 force=y entries=10
[oracle@DBsGuruN5 dbs]$ ls -lrt orapwlabdbdev
-rw-r----- 1 oracle dba 6144 Aug  14 05:25 orapwlabdbdev


24. Finally add the target in OEM, add/enable jobs in DBMS_scheduler/cronjobs, handover to the dependent team for checkout, etc as applicable if any. Click here to know about Target Blackouts ENABLE/DISABLE in OEM 13c.
