Placing a Cluster Node in Maintenance Mode
You can place an individual node in a cluster in maintenance mode to perform operations such as diagnosing an issue, cleaning up the file system, or changing the server configuration.
When My webMethods Server is in maintenance mode, the behavior of the server differs depending on the type of user:
*My webMethods and system administrators.My webMethods administrators and system administrators can log in and interact normally with My webMethods Server while the server is in maintenance mode.
*My webMethods users.My webMethods users cannot log in while the server is in maintenance mode. A My webMethods user who is already logged in will be redirected to the maintenance mode page when the user attempts to load another server page.
* To place an individual node in maintenance mode
