The Shared Enablers XDMS is a single EAR file that contains all of the Application Unique Identity Descriptors (AUIDs) from all of the other XDMS enablers.
The Shared Enablers XDMS has all of the same functionality as the other enablers, in one EAR file. The benefit of this enabler is that you do not have to set up multiple clusters or data sources for each enabler. Also, the Aggregation Proxy is not needed when using this enabler by itself, because aggregation- or enabler-specific routing is not necessary. The Aggregation Proxy is still needed, however, if domain routing is desired.
