Reserve licenses to nodes

The license server grants license to nodes on a first-come first-serve basis. If you are utilizing a centralized license server, and the specific node that you are running requires a specific license functionality, you must reserve a Communication Driver license (Standard or Professional) to the node.

If a license is reserved to a node, any other node that requests a license first will retrieve it.

For example: Consider a license server that contains a mix of standard and professional licenses. If a particular node (say, node X) requires to run multi-instance functionality, which is a professional feature, ensure to reserve a professional license to that node. Otherwise, other nodes may allocate all the available professional licenses, preventing the node X from retrieving the professional license.
