nAdminAPI, Enterprise Manager and other tools built on top of the nAdminAPI
The administration API does not support HS URL syntax or the HS feature, so you must administer the servers individually. This adds some burden in creating resources.
Datagroups are unsupported in an HS environment.
JNDI Provider URL
Although the assets within JNDI support HS, the Initial Context does not.
Language/API support
This feature supports only the Universal Messaging Client API for Java. The Universal Messaging Admin APIs for Java as well as all other language APIs (C++, .NET, JavaScript, etc.) are not supported.
