Although it is possible to make the Node Agent highly available through third-party clustering software, we do not recommend that you do so. Often a simple restart of the process solves your problem.
Therefore, before failing over the Node Agent process to another system, you should try to restart it on the local system. If you are able to restart the process locally, the downtime is greatly reduced compared with failing over to the backup system. See 3.4, Restarting WebSphere processes as an OS service for information about how to restart the process automatically.
If you decide to make your Node Agent highly available using clustering software, this section describes what consider.
