Message Bundling

Message bundling is a procedure in which notification messages can no longer be sent individually; instead, they are bundled in one large notification message and sent together to the connected destination system.

You can activate message bundling on the Message Delivery tab for the notification.

Message bundling is only supported by the following types of destination systems:

Simulation destination
MII destination
RFC destination (only RFC destination systems of the type SAP NW)
ODBC destination
Sybase ESP destination
RFC destination of the type SAP NW

Note Note

Message bundling is used for all destination systems that you assign to the notification.
Message bundling cannot be activated if you have set Process Notification Messages Exactly Once in Order on the Host tab.

End of the note.

Features

In the Message Bundling screen area, you can activate the function by selecting at least one of the checkboxes that are described below. At the same time, you define the criteria here according to which you want messages to be bundled.

Field	Description
Fixed Number of Messages	If you select this checkbox, a bundled notification message is created as soon as the number of individual messages you have specified has been reached. If you have only selected this criterion for message bundling, a bundled notification message contains exactly the number of individual messages you have specified here. The default setting is 10 messages.
Maximum Accumulation Time	Select the checkbox and, if required, enter a time period in seconds (the default setting is 60 seconds). In periodic intervals, after the agent has started, PCo bundles all individual messages that have accumulated within a notification for a specific destination system into one notification message. If you have selected both checkboxes, a bundled message is generated and sent as soon as one of the criteria has been fulfilled. In this case, a bundled notification message might contain fewer individual messages, or the bundled notification message is created in a shorter time period, as soon as the specified number of messages has been reached.

Field

Description

Fixed Number of Messages

If you select this checkbox, a bundled notification message is created as soon as the number of individual messages you have specified has been reached. If you have only selected this criterion for message bundling, a bundled notification message contains exactly the number of individual messages you have specified here. The default setting is 10 messages.

Maximum Accumulation Time

Select the checkbox and, if required, enter a time period in seconds (the default setting is 60 seconds). In periodic intervals, after the agent has started, PCo bundles all individual messages that have accumulated within a notification for a specific destination system into one notification message.

If you have selected both checkboxes, a bundled message is generated and sent as soon as one of the criteria has been fulfilled. In this case, a bundled notification message might contain fewer individual messages, or the bundled notification message is created in a shorter time period, as soon as the specified number of messages has been reached.

Example Example

You have entered 2 in the Fixed Number of Messages field. This leads to the following:

A message is generated due to a tag value change. It is put in the queue. A second message is generated after a further tag value change. It is also put in the queue. Now the messages are bundled; in other words, both messages are bundled into one notification message. This notification message is sent to the destination system.

You can display the bundled notification messages on the Messages for Bundling (agent instance) tab. (See also: Agent Instance: Displaying Messages.)

End of the example.
