Grid Grouper Registration and Discovery

Grid Grouper: Administrators Guide | Developers Guide | caGrid: Documentation Guides

The Index Service maintains a registry of services operating in the Grid. Services that wish to be listed in the Index Service's registry must register with the Index Service. When services register with the Index Service they can publish metadata about themselves. Clients and other services can discover registered services by query metadata published to the Index Service by registered services. The GTS provides the ability to register itself with the index service. When registering the GTS publishes its Service Metadata to the index service.

The configuration for registering with the Index Service is contained in the properties file, GTS_HOME/deploy.properties. This configuration allows registration to be enabled and disabled and allows the configuration of which Index Service to register to. The table below list each of registration properties that can be configured in the file GTS_HOME/deploy.properties:

Property Name	Value(s)	Description
perform.index.service.registration	true of false	Whether or not the service should register with the Index Service
index.service.url	URL	The URL of the Index Service to register with.
