Control-M/Server-Agent Communication

Control-M/Server and Agent communicate over one of the following connection types:

• Transient Connection: A connection between Control-M/Server and Agent that is initiated only when one component must communicate with another and the connection is dropped after the information is shared. (Default).

• Persistent Connection: A connection between Control-M/Server and Agent that remains open. Persistent connections are often established when one component is inside a firewall and needs a constant connection via a port.

The following procedures describe how to configure persistent connections:

• Configuring a Persistent Connection from a Control-M/Server to an Agent

• Configuring a Persistent Connection from an Agent to a Control-M/Server
