When the PowerCenter Integration Service runs on a node, the Load Balancer performs the following steps to dispatch a task:
The Load Balancer checks resource provision thresholds on the node. If dispatching the task causes any threshold to be exceeded, the Load Balancer places the task in the dispatch queue, and it dispatches the task later.
The Load Balancer checks different thresholds depending on the dispatch mode.
The Load Balancer dispatches all tasks to the node that runs the master PowerCenter Integration Service process.
