Understanding Transaction Control Units

Understanding Transaction Control Units

A transaction control unit is the group of targets connected to an active source that generates commits or an effective transaction generator. A transaction control unit is a subset of a target load order group and may contain multiple target connection groups.
When the Integration Service reaches the commit point for all targets in a transaction control unit, it issues commits sequentially for each target.
