Data Enrichment requirements

Data Enrichment is a Java application that is installed as part of the Endeca Server installation. Data Enrichment plugins are used in the context of Studio, and are known in Studio as Enrichments.

In the Endeca Server cluster, each machine on which the Endeca Server software is installed also contains the Data Enrichment plugins. This means that when you configure the WebLogic domain for Endeca Server, it hosts the Endeca Server Java application, and also the Data Enrichment Java application, oracle.endeca.enrichment_framework.

For Enrichments to be used in Studio, the Data Enrichment Java application has to be properly configured in WebLogic Server on all machines hosting the Endeca Server, in the Endeca Server cluster. The following requirements exist:

Data Enrichment Framework Java application must be hosted on each Managed Server in the WebLogic domain. In the Endeca Server cluster, both the Endeca Server Java application and the Data Enrichment Framework Java application are hosted on each of the Managed Servers in the WebLogic domain for the Endeca Server.
EndecaServer.properties file should specify a shared storage location for two Data Enrichment directories.The two directories, endeca-data-enrichment-pluginsDir and endeca-data-enrichment-resourcesDir, should point to their directories on the shared file system. You specify these settings as a step in the overall procedure for installing and deploying an Endeca Server cluster. For information on this step, see Changing settings in EndecaServer.properties.
Data Enrichment plugins rely on JMS configuration in WebLogic. For Data Enrichment plugins to work in the Endeca Server cluster (so that they can be used in Studio), each machine hosting the Data Enrichment Framework application must be configured to use JMS (Java Messaging Service). You configure JMS queues for Data Enrichment as a step in the overall procedure for installing and deploying an Endeca Server cluster. For information on this specific step, see Step 9: Configuring JMS settings.
Data Enrichment plugins (used via Studio as Enrichments), require adding memory on each machine hosting Endeca Server. If you are planning to use data enrichment plugins (such as term extraction) in Studio, consider adding additional memory of about 10GB per each instance of Data Enrichment plugin that is expected to run concurrently in the data domain. In other words, if users in the data domain plan to run term extraction, for each such process, additional memory should be provisioned on all Endeca Server machines hosting this data domain.
