Enabling indexing on a federated system

The distributed Process Federation Server index enables process participants to see a consolidated list of both BPD- and BPEL-related tasks from all the business process management systems in the federated environment. For data from a federated system to appear in the index, you must enable indexing on the system.

About this task

The distributed index ensures that users have fast access to federated data, and relieves back-end systems from expensive queries. There is an indexing service for each federated system in the federated environment, and a common REST-based query service that provides data to users. The Process Federation Server index is based on Elasticsearch, an open source search service.

You enable indexing by creating change log tables on each of the federated systems and then configuring the systems to update the tables. You can then configure the indexing service for a federated system through entries in the server.xml configuration file on Process Federation Server.
