Measurement
Unit |
Interpretation |
| Utilization |
The percentage of the background processing capacity currently utilized. The value is averaged over the background work processes and by default, averaged over the last hour. |
Percent
|
Utilization and Sys_wide_queue_length measures show if there is a serious bottleneck in the background processing capacity. The optimal situation is to maintain a high level of utilization of the work processes and a short wait queue.
|
| Bkground_work_procs |
The number of background work processes running on an application server |
Number
|
It does not make sense to have more than 2-3 work processes per CPU on a background server, as these work processes will already be fully utilizing the CPU. Set the number of these processes using the system parameter rdisp/wp_no_btc.
|
| Server_queue_length |
The number of released jobs that are explicitly to be executed on this application server, but for which there are no free background work processes. |
Jobs
|
An alert for the Server_queue_length measure when there is a short Sys_wide_queue_length suggests that the distribution of jobs is not optimal. Only specify a target server if it is absolutely necessary.
