Starting a channel

 

A channel can be caused to start transmitting messages in one of four ways. It can be:

• Started by an operator (not receiver, cluster-receiver or server-connection channels).

• Triggered from the transmission queue. This applies to sender channels and fully qualified server channels (those which specify a CONNAME) only. You will need to prepare the necessary objects for triggering channels.

• Started from an application program (not receiver, cluster-receiver or server-connection channels).

• Started remotely from the network by a sender, cluster-sender, requester, server, or client-connection channel. Receiver, cluster-receiver and possibly server and requester channel transmissions, are started this way; so are server-connection channels. The channels themselves must already be started (that is, enabled).

Because a channel is ‘started’ it is not necessarily transmitting messages, but, rather, it is ‘enabled’ to start transmitting when one of the four events described above occurs. The enabling and disabling of a channel is achieved using the START and STOP operator commands.
