ORACLE APPS R12 CLONING STEPS

In this article, we will set up Oracle APPS R12 on the server Oracle Linux. Follow the below ORACLE APPS R12 CLONING STEPS.

(ON PRODUCTION APPS TIER)

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Run adpreclone.pl on Production server. (It will create EBSapps on production)

[appl@DBGURU]$ cd $ADMIN_SCRIPTS_HOME

 perl adpreclone.pl appsTier

Now, move EBSapps from Production server to test server through scp. Before moving EBSapps on test server rename the existing EBSapps from there and delete or rename fmw also.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

(ON TEST APPS TIER)

• Stop application – (adstpall.sh will stop the application)

[appltest@DBGURU]$ cd $ADMIN_SCRIPTS_HOME

./adstpall.sh apps/password

• check if the Concurrent processes are still running by-

[appltest@DBGURU]$ ps -ef | grep FNDLIBR

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

TEST DATABASE TIER – (DB Cloning)

• Give permission to rman directory  for backup –

[DB@DBGURU]$ chmod 777 / RMAN_BACKUP

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, we need to Shutdown the database –

[DB@DBGURU]$ sqlplus / as sysdba

shutdown immediate;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Then Startup database in restricted mode –

startup mount restrict;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Will drop the existing database –

drop database;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, we need to change the db_name as like production in pfile at test db tier –

[DB@DBGURU]$ cd $ORACLE_HOME/dbs

*.db_name=’TEST‘#Reset to original value by RMAN

Change the db_name –

*.db_name=’PROD‘#Reset to original value by RMAN

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, startup database in nomount  mode using modified pfile –

[DB@DBGURU]$ sqlplus / as sysdba

SQL> startup nomount pfile='/db/12.2.0/dbs/init.ora';

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, we will restore and recover the database and for that we need to Go to rman backup location –

[DB@DBGURU]$ /RMAN_BACKUP/20200805_LEVEL0/ 20200805_LEVEL0

• connect with  rman target –

[DB@DBGURU]$  rman target /

• Restore controlfile from backup –

restore controlfile from '/RMAN_BACKUP/20200805_LEVEL0/RMAN_CTLc-21359790-20200805-00';

RMAN> alter database mount;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, run Catalog start with command –

RMAN> catalog start with'/RMAN_BACKUP/20200805_LEVEL0/20200805_LEVEL0';

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, Crosscheck the backups-

RMAN> crosscheck backup;

RMAN> report obsolete;

RMAN> delete obsolete;

RMAN> delete expired backup;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Then run the RMAN restoration scripts with set new name of datafiles (RMAN Script)

[DB@DBGURU]$ /home/db/restore.sql

[DB@DBGURU]$ cat restore.sql

run{

ALLOCATE CHANNEL c1 DEVICE TYPE DISK;

ALLOCATE CHANNEL c2 DEVICE TYPE DISK;

ALLOCATE CHANNEL c3 DEVICE TYPE DISK;

ALLOCATE CHANNEL c4 DEVICE TYPE DISK;

ALLOCATE CHANNEL c5 DEVICE TYPE DISK;

set newname for datafile 1 to '/u02/oracle/test/datafiles/system01.dbf';

set newname for datafile 2 to '/u02/oracle/test/datafiles/ temp01.dbf';

set newname for datafile 3 to '/u02/oracle/test/datafiles/sysaux01.dbf';

set newname for datafile 4 to '/u02/oracle/test/datafiles/app_data01.dbf';

set newname for datafile 5 to '/u02/oracle/test/datafiles/app_ind01.dbf';

restore database;

switch datafile all;

switch tempfile all;

recover database;

RELEASE CHANNEL c1;

RELEASE CHANNEL c2;

RELEASE CHANNEL c3;

RELEASE CHANNEL c4;

RELEASE CHANNEL c5;

}

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

NOTE – If you receive the error after recover database command (media recovery requesting unknow archivelog for thread 1 with sequence  12345 and for starting scn of ….) then Copy 3 digits before and 3 digits after archivelogs  from production and move to test server and then run below recovery command.

RMAN> run{

set until sequence 12345;

recover database;

}

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• After recovery we need to rename the prod redo logs –

[DB@DBGURU]$ sqlplus / as sysdba

SQL> col MEMBER for a50;

select group#,member from v$logfile;

ALTER DATABASE RENAME FILE '/prod/redo/log01a.dbf' TO '/db/oracle/test/redo/log01a.dbf';

ALTER DATABASE RENAME FILE '/prod/redo/log02a.dbf' TO '/db/oracle/test/redo/log02a.dbf';

ALTER DATABASE RENAME FILE '/prod/redo/log03a.dbf' TO '/db/oracle/test/redo/log03a.dbf';

ALTER DATABASE RENAME FILE '/prod/redo/log04a.dbf' TO '/db/oracle/test/redo/log04a.dbf';

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Change the block tracking and open db in resetlogs-

SQL> show parameter change;

SQL> alter database disable block change tracking;

SQL> alter database open resetlogs;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, change the password of sys user –

[DB@DBGURU]$ sqlplus / as sysdba

SQL> ALTER USER sys IDENTIFIED BY dbguru1234;

Test the connection –

[DB@DBGURU]$ connect sys/dbguru1234 as sysdba

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• shut down the database –

SQL> Shut immediate;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• startup db in mount phase and alter it in noarchive log mode –

SQL> Startup mount;

SQL> alter database noarchivelog;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, check the default temp tablespace via below query –

SQL> column property_value format a25

SELECT property_name,property_value FROM DATABASE_PROPERTIES where PROPERTY_NAME='DEFAULT_TEMP_TABLESPACE';

• Create new temp tablespace and make it default and drop the previous one –

SQL> create TEMPORARY tablespace NEWTEMP tempfile'/u02/oracle/test/datafiles/newtemp01.dbf' size 15G;

MAKE IT DEFAULT –

SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE NEWTEMP;

DROP previous temp –

SQL> DROP TABLESPACE TEMP including contents and datafiles;

• Now, shoutdown the database –

Shut immediate;

Startup mount –

Startup mount;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, run nid command –

[DB@DBGURU]$ nid TARGET=sys/dbguru1234 DBNAME=TEST

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, change the name of database from PROD to TEST in pfile.

[DB@DBGURU]$ cd $ORACLE_HOME/dbs

*.db_name=’PROD‘#Reset to original value by RMAN

Change this name –

*.db_name=’TEST‘#Reset to original value by RMAN

Open the database in resetlog mode –

SQL> Alter database open resetlogs;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, go to appsutil directory and run autounfig.sh on Database Tier

[DB@DBGURU]$ cd $ORACLE_HOME/appsutil

sh adautocfg.sh (It will ask apps user password)

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Change the system user password –

SQL> alter user system identified by manager account unlock;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Run FND_CONC_CLONE.SETUP_CLEAN command –

SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;

SQL> commit;

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

TEST APPLICATION TIER – (Application Cloning)

************* steps Before Application Cloning ******************

• go to /var/opt/oracle

[appltest@DBGURU]$ cd /var/opt/oracle

[appltest@DBGURU]$ cat oraInst.loc

inventory_loc=/var/opt/oracle/oraInventory

inst_group=dba               —- this entry should be there if not you can write

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• go to /var/opt/oracle/oraInventory

[appltest@DBGURU]$ cd /var/opt/oracle/oraInventory

Rename CONTENTSXML –

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• go to  /appl/fs1/EBSapps/comn/clone/bin

[appltest@DBGURU]$ cd /appl/fs1/EBSapps/comn/clone/bin

and run adcfgclone.pl on  application server –

Choose a value which will be set as APPLPTMP value on the target node [1] : 1

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• Now, login with application user and change the apps password using below command –
