Removing a Server from a Stateful Cluster
If you no longer want a server to be part of a cluster, disable clustering on that server.
To remove a server from a stateful cluster
Important:
If you do not take the server offline before removing it from the cluster, the server will continue to receive transactions, but the transactions will not be integrated into the database and may be lost if the server is restored to the cluster.
2. In Integration Server Administrator, go to Settings > Clustering > Edit Cluster Settings and click Disable Cluster.
3. Click Save Settings and then restart the server.
Note:
Until you restart the server, it will remain in the list of cluster hosts on other Integration Servers in the cluster.
