Data Integration Hub Server Cluster Components

The

Data Integration Hub

server cluster handles document and event processing between the

Data Integration Hub

server, JMS Broker, Managed File Transfer, and PowerCenter.

The

Data Integration Hub

server cluster typically consists of the following components:

Data Integration Hub

server. Processes events and documents.

Shared file system. Contains the document store, File Receive and File Send endpoint documents, archive service, and the JMS messages data directory.

PowerCenter grid. Processes documents from the

Data Integration Hub

server with workflows.

The following image shows an example of

an active/active

Data Integration Hub

server cluster configuration:

This cluster consists of two

Data Integration Hub

server instances, a PowerCenter environment, and a shared file system. The

Data Integration Hub

server instances also include the optional Managed File Transfer component. The communication lines between the

Data Integration Hub

servers and the PowerCenter grid represent the RMI and Web Service message flows.

This cluster configuration does not require you to install the

Data Integration Hub

server on each of the PowerCenter nodes. The installation location has no impact on the necessary configuration changes.
