Stopping an individual Grid node

Normally, you do not stop individual application nodes. Instead, you stop an entire application and, as a result, all nodes belonging to the application will be stopped. However, there are situations when you want to stop an individual application node.

For example:

• A node is experiencing problems and you need to stop it, perhaps with the intention of starting a new node to replace the stopped one.
• The application has been started in multiple instances (nodes) but all that capacity is no longer needed, so some of the nodes can be removed in order to free resources.
• You want to clear a particular host in a multi-host grid from all nodes in order to perform some maintenance on that host.

Considerations before stopping a node:

• Should the node be put in an offline state first?
• If the application node is the only one of its kind, the application may stop working. Should a new similar application node be started first before the node is stopped?
• Applications are implemented differently. Some applications manage their nodes themselves. Consult the documentation of the application. Does the documentation recommend some alternative procedure to stopping the node in this case?
