When the PowerCenter Integration Service runs on a grid, the Load Balancer performs the following steps to determine on which node to run a task:
The Load Balancer verifies which nodes are currently running and enabled.
If you configure the PowerCenter Integration Service to check resource requirements, the Load Balancer identifies nodes that have the PowerCenter resources required by the tasks in the workflow.
The Load Balancer verifies that the resource provision thresholds on each candidate node are not exceeded. If dispatching the task causes a threshold to be exceeded, the Load Balancer places the task in the dispatch queue, and it dispatches the task later.
The Load Balancer checks thresholds based on the dispatch mode.
The Load Balancer selects a node based on the dispatch mode.
