Parameter
rdisp/scheduler/prio_low/max_quota
Short text
Maximum quota for requests with low priority
Parameter Description
The kernel scheduler normally distributes incoming dialog requests in accordance with their priority to all dialog work processes. High-priority requests have priority.
In contrast to this arrangement, this parameter limits the maximum number of dialog requests with low priority that can be processed at the same time. Even if there are still free dialog work processes and there are no requests with high priority, the system will never use more than the number of dialog work processes specified by the parameter to process requests with low priority.
The system assigns low priority to all RFC dialog requests that are triggered by a background request.
The intention behind this parameter is to limit the maximum number of simultaneously-processed dialog requests with low priority. This is to ensure that there are always sufficient resources for dialog requests with normal and high priority.
You cannot choose a value smaller than the effective value for rdisp/scheduler/prio_normal/max_quota. If you do not want to differentiate further between normal and low priority, you can set both parameters to the same value.
Caution:
For compatibility reasons this parameter does not work when either of the parameters rdisp/rfc_min_wait_dia_wp or rdisp/http_min_wait_dia_wp has been explicitly set. Since you can configure the quotas according to priority with the new rdisp/scheduler/… parameters, you should use the new parameters.
Application Area
Dispatcher
Parameter Unit
You can specify an absolute value (number of work processes) for the quota or add “%” to specify the value as a percentage. If you do not specify a value, or the value is 100%, no maximum quota is used.
Default Value
80%
