System Policies panel
Use the System Policies panel to modify the workload management system policies. The corresponding current system usage is displayed for these policies.
You can set threshold values for these system policies: Job Count, CPU Usage, Memory Usage, and Job Start. Set the required value for the threshold and click Apply.
- Job Count
- Specify the maximum number of concurrent running parallel and server jobs allowed on the system.
The default value is 20 concurrent running jobs. Note: Job count excludes sequence jobs.
- CPU Usage
- Specify the maximum CPU usage that is allowed on the system. If the current CPU usage exceeds this value, the job is not allowed to start. The default value is 80 percent CPU usage.
- Memory Usage
- Specify the maximum memory usage that is allowed on the system. If the memory usage exceeds this value, the job is not allowed to start. The default value is 80 percent memory usage.
- Job Start
- Specify the maximum number of parallel and server jobs that are allowed to start in the specified number of seconds. The default value is 100 jobs in 10 seconds.
The workload management process checks the system resource usage against the four system policies to determine if another job can be started. If all the checks are successful, workload management process checks the queue definitions to determine which job is started. If one of the checks is not successful, a job is not started until more resources are available.
If job monitoring is enabled, the Job Count, CPU Usage, and Memory Usage system policies also show the current system values. You can click the current system values to see further details. If the current system value exceeds the threshold value for a system policy, the current system value is shown with a red background.
