The Group Management Service (GMS) is an in-process service that provides cluster monitoring, cluster membership, and group communication services. The GMS performs the following functions:
Notifies registered modules in a GlassFish Server instance when one or more member instances are added to or removed from a cluster, or are suspected or confirmed to have failed.
Provides the ability to send and receive messages between a group of processes.
The General Information page for the cluster opens.
This option is selected by default. To disable the GMS for the cluster, remove the check from the GMS Enabled checkbox.
If enabled, the Group Management Service is started in each server instance in the cluster and in the Domain Administration Server (DAS). The DAS participates in each cluster that has GMS enabled.
