Port Usage Control

GigaSpaces space and client components open different ports in various situations. The following list describes the different ports used by GigaSpaces and how these can be modified:

Property name	Description	Default value
com.gs.transport_protocol.lrmi.bind-port	LRMI listening port Used with client-space and space-space communication.	variable , random
com.gigaspaces.system.registryPort	RMI registry listening port Used as an alternative directory service. The RMI registry can also be changed by providing environment variable GS_JMX_REMOTE_BASE_PORT. For details, see JMX Management.	10098 and above.
com.gigaspaces.system.registryRetries	RMI registry Retries Used as an alternative directory service.	Default is 20.
com.gigaspaces.start.httpPort	Webster listening port Internal web service used as part of the application deployment process.	9813
export GS_MANAGER_SERVERS="hostname;lus=4174" com.gs.multicast.discoveryPort com.sun.jini.reggie.initialUnicastDiscoveryPort (optional)	LUS Lookup Service. This service provides a mechanism for services to discover each other. Each service can query the lookup service for other services, and register itself in the lookup service so other services may find it. port Should be set on clients and servers.	4174
com.gs.multicast.enabled	Recommended to set to false, to disable multicast discovery.	true
org.openspaces.launcher.port	Web UI port	8099
com.gs.manager.rest REpresentational State Transfer. Application Programming Interface An API, or application programming interface, is a set of rules that define how applications or devices can connect to and communicate with each other. A REST API is an API that conforms to the design principles of the REST, or representational state transfer architectural style..port	REST Manager port If gs.sh CLI tools are run outside the cluster, this needs to be set.	8090
com.gs.ui.metrics.db.port	The metrics DB is used to track metrics within the cluster.	9101
com.gs.zookeeper.client.port	Zookeeper Apache Zookeeper. An open-source server for highly reliable distributed coordination of cloud applications. It provides a centralized service for providing configuration information, naming, synchronization and group services over large clusters in distributed systems. The goal is to make these systems easier to manage with improved, more reliable propagation of changes. client port Should be set on clients and servers.	2181
export GS_MANAGER_SERVERS="hostname;zookeeper=2888:3888;lus=4174" com.gs.manager.zookeeper.discovery.port (optional on server, set on client) com.gs.manager.zookeeper.leader-election.port (optional on server, set on client)	Zookeeper discovery port Should be set on clients and servers.	2888
export GS_MANAGER_SERVERS="hostname;zookeeper=2888:3888;lus=4174" com.gs.manager.zookeeper.discovery.port (optional on server, set on client) com.gs.manager.zookeeper.leader-election.port (optional on server, set on client)	Zookeeper leader election Should be set on clients and servers.	3888

• When starting a space and providing the port as part of the URL - i.e. java://localhost:PORT/container/space - the specified port will be used both for the RMI registry listener and also for the container to register into the RMI registry.
• The Jini Lookup Service uses unicast and multicast announcements and requests.
• The multicast discovery protocol uses ports 4174.
• You can completely disable multicast announcement traffic. Refer to the Lookup Service Configuration or GigaSpaces Over a Firewall sections for more details.
• When running a clustered space using replication via multicast, additional ports are used.
