1. Remove Oracle Instance


i) Remove Instance from OEM Database Control Monitoring – I did not configured. Hence  ignoring.
From: Node RAC1
Note: Run the emca command from any node in the cluster, except from the node where the instance we want to stop from being monitored is running.

emctl status dbconsole
emctl status agnet
emca -displayConfig dbcontrol -cluster —
emca -deleteInst db


ii) Backup OCR
From: Node RAC1

[root@rac1 ~]# ocrconfig -manualbackup
rac1     2015/06/19 23:38:03     /u01/app/11.2.0/grid/cdata/rac-scan/backup_20150619_233803.ocr
[root@rac1 ~]#

Note: that voting disks are automatically backed up in OCR after the changes we will be making to the cluster.


iii) Remove instance name from services
From node RAC1
Note:
Before deleting an instance from an Oracle RAC database, use either SRVCTL or Oracle Enterprise Manager to do the following:
If you have services configured, then relocate the services
Modify the services so that each service can run on one remaining instance
Ensure that the instance to be removed from an administrator-managed database is neither a preferred nor an available instance of any service

[oracle@rac1 ~]$ srvctl status service -d nike -s nike_srv -v
Service nike_srv is running on instance(s) nike1  <<<< service running only on instance nike1. Hence no issue here. If service running on instance 2, then we need to relocate service before instance delete.
[oracle@rac1 ~]$
[oracle@rac1 ~]$ srvctl config service -d nike -s nike_srv -v
Service name: nike_srv
Service is enabled
Server pool: nike_nike_srv
Cardinality: 2

[oracle@rac1 ~]$ srvctl modify service -d nike -s nike_srv -n -i nike1 <<<
[oracle@rac1 ~]$ srvctl config service -d nike -s nike_srv -v
Service name: nike_srv

[oracle@rac1 ~]$

[oracle@rac1 ~]$ srvctl status service -d nike -s nike_srv -v
Service nike_srv is running on instance(s) nike1  <<<
[oracle@rac1 ~]$


iv) Remove Instance from the Cluster Database
From Node RAC1 as Oracle Home owner.

[oracle@rac1 ~]$ srvctl config database -d nike -v
Database unique name: nike
Database name: nike
Oracle home: /u01/app/oracle/product/11.2.0/db_1 <<<<<

2. Remove Oracle Database Software

i) Verify Listener Not Running in Oracle Home >>> Please ignore this step because no listener is running from RDBMS HOME.

From Node RAC2

[oracle@rac2 ~]$ ps -ef | grep tns
root         9     2  0 Jun19 ?        00:00:00 [netns]
oracle    4372     1  0 Jun19 ?        00:00:01 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER -inherit  <<< Listner is running form GI Home.
oracle    4408     1  0 Jun19 ?        00:00:01 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER_SCAN1 -inherit
oracle   11983 11943  0 00:43 pts/1    00:00:00 grep tns
[oracle@rac2 ~]$

[oracle@rac2 ~]$ srvctl config listener -a (If listener is running from GI Home then ignore this step)
Name: LISTENER
Network: 1, Owner: oracle
Home: 
  /u01/app/11.2.0/grid on node(s) rac1,rac2 
End points: TCP:1521
[oracle@rac2 ~]$

Note: If any listeners were explicitly created to run from the Oracle home being removed, they would need to be disabled and stopped.
srvctl disable listener -l  -n 
srvctl stop listener -l  -n


ii) Update Oracle Inventory – (Node Being Removed)

From node RAC2

[oracle@rac2 ~]$ cd $ORACLE_HOME/oui/bin
[oracle@rac2 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES={rac2}" -local
Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB.   Actual 2047 MB    Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.
[oracle@rac2 bin]$


iii) Remove instance nike2 entry from /etc/oratab

From node RAC2 

+ASM2:/u01/app/11.2.0/grid:N            # line added by Agent >> We need to remove all database instance entries from oratab except ASM entries.
[oracle@rac2 ~]$


iv) De-install Oracle Home (Non-shared Oracle Home)

From Node RAC2 as Oracle Home owner

[oracle@rac2 ~]$ cd $ORACLE_HOME/deinstall

Specify all RAC listeners (do not include SCAN listener) that are to be de-configured [LISTENER_1,LISTENER,LISTENER_SCAN2,LISTENER_SCAN1]:LISTENER

At least one listener from the discovered listener list [LISTENER_1,LISTENER,LISTENER_SCAN2,LISTENER_SCAN1] is missing in the specified listener list [LISTENER]. The Oracle home will be cleaned up, so all the listeners will not be available after deinstall. If you want to remove a specific listener, please use Oracle Net Configuration Assistant instead.
