Resource Provision Thresholds

Resource Provision Thresholds

The Load Balancer uses resource provision thresholds to determine the maximum load acceptable for a node. The Load Balancer can dispatch a task to a node when dispatching the task does not cause the resource provision thresholds to be exceeded.
The Load Balancer checks the following thresholds:
  • Maximum CPU Run Queue Length. The maximum number of runnable threads waiting for CPU resources on the node. The Load Balancer excludes the node if the maximum number of waiting threads is exceeded.
    The Load Balancer checks this threshold in metric-based and adaptive dispatch modes.
  • Maximum Memory %. The maximum percentage of virtual memory allocated on the node relative to the total physical memory size. The Load Balancer excludes the node if dispatching the task causes this threshold to be exceeded.
    The Load Balancer checks this threshold in metric-based and adaptive dispatch modes.
  • Maximum Processes. The maximum number of running processes allowed for each PowerCenter Integration Service process that runs on the node. The Load Balancer excludes the node if dispatching the task causes this threshold to be exceeded.
    The Load Balancer checks this threshold in all dispatch modes.
If all nodes in the grid have reached the resource provision thresholds before any PowerCenter task has been dispatched, the Load Balancer dispatches tasks one at a time to ensure that PowerCenter tasks are still executed.
You define resource provision thresholds in the node properties.
