REMOVE / DELETE NODE RAC NODE
FROM 11gR2 CLUSTER
In
today's demonstration, I am gonna show you how to remove node from existing or
dead cluster. Here we have 3 node RAC
11gR2 (11.2.0.3) Grid Infrastructure and cluster database.
SERVER : rac121.ora.com
rac122.ora.com
rac123.ora.com
OS : Red Hat Enterprise Linux Server release
6.5 (x64)
INSTANCE : orcl1
orcl2
orcl3
Database : orcl
In
this scenarios I am going to delete node3 (rac123.ora.com) from my existing
cluster.
ON NODE 1
Get
the details for existing cluster status.

For
this demonstration I have stop and disable the cluster services. As I am going to delete the dead cluster from
my existing cluster.
Now check
the status after disable and stopped component on node3 (rac123)

Before
installation the node removal process we have to ensure that we must proceed
the OCR backup for the safer size if anything goes wrong.
