Applies to:Oracle Database - Enterprise Edition - Version 18.104.22.168 and later
Information in this document applies to any platform.
This document is intented to provide the steps to be taken to remove a node from the Oracle cluster.
The node itself is unavailable due to some OS issue or hardware issue which prevents the node from starting up.
It is also possible to use this note to remove the node and add it back in situations where the GRID home has been corrupted and the clusterware needs to be rebuilt from the ground up on the problem node.
This document will provide the steps to remove such a node so that it can be added back after the node is fixed.
The steps to remove a node from a Cluster is already documented in the Oracle documentation at
This note is different because the documentation covers the scenario where the node is accessible and the removal is a planned procedure.
This note covers the scenario where the Node is unable to boot up and therefore it is not possible to run the clusterware commands from this node.
Please note that after using the information provided here to remove the 'problem' node, if it is subsequently restarted at a later date, it will rejoin the Cluster.
This fact has been reported under internal bug:17058972 - Development are currently considering this bug.
