ondemand   Only transmit messages when the QAnywhere client application makes the appropriate method call.

The QAManager PutMessage() method causes messages to be queued locally. These messages are not transmitted to the server until the QAManager TriggerSendReceive() method is called. Similarly, messages waiting on the server are not sent to the client until TriggerSendReceive() is called by the client.

When using the ondemand policy, the application is responsible for causing a message transmission to occur when it receives a push notification from the server. A push notification causes a system message to be delivered to the QAnywhere client. In your application, you may choose to respond to this system message by calling TriggerSendReceive().

For an example, see System queue.

scheduled   Transmit messages at a specified interval. The default value is 900 seconds (15 minutes).

When a schedule is specified, every n seconds the Agent performs message transmission if any of the following conditions are met:

You can call the trigger send/receive method to override the time interval. It forces message transmission to occur before the time interval elapses.

automatic   Transmit messages when one of the events described below occurs.

The QAnywhere UltraLite Agent attempts to keep message queues as current as possible. Any of the following events cause messages queued on the client to be delivered to the server and messages queued on the server to be delivered to the client:

rules-file   Specifies a client transmission rules file. The transmission rules file can indicate a more complicated set of rules to determine when messages are transmitted.
