I encountered a problem where one of our Production instance (msisvr145 is the nodename) where listener cannot up. It exits to status 1. As we investigate it, there is a server in the network the uses its priv IP address and we found out that it is used by our Test Instance.

When I shutdown the test Instance, the Listener of msisvr145 is now working. Now my problem, there are times that I need to shutdown the test instance first in order for me to start the listener of msisvr145.

I checked the cluster.conf of test and I saw the IP of the ms145 there.

node:
ip_port = 7777
ip_address = 1.1.1.25
number = 0
name = dgpsvr205
cluster = ocfs2

node:
ip_port = 7777
ip_address = 1.1.1.35
number = 1
name = dgpsvr215
cluster = ocfs2

node:
ip_port = 7777
ip_address = 1.1.1.45
number = 2
name = msisvr145
cluster = ocfs2

cluster:
node_count = 3


My question is, is it Ok to delete node:
node:
ip_port = 7777
ip_address = 1.1.1.45
number = 2
name = msisvr145
cluster = ocfs2

in the cluster.conf ?

or is there a way to flushed out this node in the list of the RAC?

Hope someone would help me
