Removing Grid Control Agent from One Node Only in Silent Mode

This blog is for situation where grid control agent is removed from one node in the cluster.

1. Stop the agent on the remote host

2. Run the following on the node on which agent is being removed

/opt/app/oracle/grid_agent/agent11g/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/opt/app/oracle/grid_agent/agent11g "CLUSTER_NODES={rac2}" -local
Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB.   Actual 4094 MB    Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /opt/app/oracle/oraInventory

3. Deinstall agent on the node oracle doc says to use -forceDeinstall but installer complains about this.

oui/bin/runInstaller -silent  "REMOVE_HOMES={/opt/app/oracle/grid_agent/agent11g}" -deinstall -waitForCompletion -removeallfiles -local -forceDeinstall
Starting Oracle Universal Installer...
