Configuring the TIBCO BusinessEvents DataGrid Discover URL

When a cluster starts up, and when new members join a cluster, a discovery process enables the members to discover each other. The discover URL specifies how an engine (node) listens for discovery requests from nodes attempting to join the cluster.

After the discovery is complete, the members communicate internally using a listen URL (explained in Configuring the TIBCO BusinessEvents DataGrid Listen URL).

Two types of discovery are available:

  • Multicast discovery (PGM)
  • Unicast discovery (TCP), also known as "well-known address" discovery

Configuration for both discovery methods is explained as follows.

Note: A TIBCO BusinessEvents DataGrid cluster is also known as a metaspace.

A Core Engine is a node in the metaspace.
