Batch Heartbeat Interval (BATCHHB)

This attribute allows a sending channel to verify that the receiving channel is still active just before committing a batch of messages.

The batch heartbeat interval thus allows the batch to be backed out rather than becoming in-doubt if the receiving channel is not active. By backing out the batch, the messages remain available for processing so they could, for example, be redirected to another channel.

If the sending channel has had a communication from the receiving channel within the batch heartbeat interval, the receiving channel is assumed to be still active, otherwise a 'heartbeat' is sent to the receiving channel to check. The sending channel waits for a response from the receiving end of the channel for an interval, based on the number of seconds specified in the channel Heartbeat Interval (HBINT) attribute.

The value is in milliseconds and must be in the range zero through 999999. A value of zero indicates that batch heart beating is not used.

This attribute is valid for channel types of:

• Sender
• Server
• Cluster sender
• Cluster receiver
