The end-to-end system consists of two cooperating components, both of which are specified by the OMA v2.0 specification. The components are the Aggregation Proxy and the IBM® WebSphere® XML Document Management Server Component (IBM XDMS).
Both component subsystems run in a WebSphere Application Server Network Deployment environment and can be configured on separate physical servers and clusters to provide scaling flexibility. IBM XDMS requires a DB2® or Oracle database for storage of user documents. IBM XDMS also requires a JMS-based messaging engine for communication within the cluster.
