Reflection of my thoughts and technical expriences: Deleting Node from the RAC Cluster using "dbca -silent -deleteInstance" Option

Procedure to Removing Node from the Cluster:

· You cannot simply remove the node from the cluster

· Oracle central inventory on each node has information about all nodes

· The Oracle Cluster Registry (OCR) contains information about all the nodes

Step-1: Check the status of Database Instances:

[oracle@oel72-rac1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node oel72-rac1
Instance orcl2 is running on node oel72-rac2
[oracle@oel72-rac1 ~]$

Step-2: Login to Node-1 (oel72-rac1) and execute "dbca -silent -deleteInstance" option

Note: If you execute from Node-2 (oel72-rac2), you will get the following error.

[oracle@oel72-rac2 ~]$ dbca -silent -deleteInstance -nodeList oel72-rac2 -gdbName orcl -instanceName orcl2 -sysDBAUserName sys -sysDBAPassword oracle

Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/orcl.log" for further details.

[oracle@oel72-rac2 ~]$ cat /u01/app/oracle/cfgtoollogs/dbca/orcl.log

The instance "orcl2" is a local instance. You cannot delete the local instance. Please try this operation from another node in the cluster

[oracle@oel72-rac2 ~]$

Note: We can "Instance Management" option from DBCA and followed by "Delete Instance" option.

[oracle@oel72-rac1 ~]$ . oraenv

ORACLE_SID = [orcl1] ? orcl1

The Oracle base remains unchanged with value /u01/app/oracle

[oracle@oel72-rac1 ~]$

[oracle@oel72-rac1 ~]$ cd $ORACLE_HOME

[oracle@oel72-rac1 db_1]$ cd bin

[oracle@oel72-rac1 bin]$ ls -lrth dbca*

-rwxr-xr-x. 1 oracle oinstall 6.2K Jul 16 01:53 dbca

[oracle@oel72-rac1 bin]$

[oracle@oel72-rac1 bin]$ dbca -silent -deleteInstance -nodeList oel72-rac2 -gdbName orcl -instanceName orcl2 -sysDBAUserName sys -sysDBAPassword oracle
