Universal Message Service (OMS) sends and receives messages between the cluster nodes and Agents.

OMS consists of an OMS Server and an OMS Administration Utility. The OMS clients - cluster nodes and Agents - establish persistent TCP/IP socket connections with the OMS Server.

OMS provides for reliable message communication by persisting all OMS queued messages to persistent storage. The OMS Server maintains OMS queues in an OMS message database that resides on persistent storage.

See Universal Message Service (OMS) for detailed information on OMS.

 uc.db.name=uc
 uc.db.rdbms=mysql
 uc.db.url=jdbc:mysql://10.10.1.1/
</pre>
