rdisp/rfc_max_queue 

Definition

This parameter specifies the contingent for the maximum number of outstanding requests in the dialog queue.

Use

RFC is executed on the target server in a dialog work process. Therefore, if there is currently no free dialog work process, the request is placed in the dialog queue of the dispatcher. You should ensure that the queue never becomes full.

The value is given as a percentage of the entire dialog queue. In other words, it is dependent on the value currently set in the profile. The parameter rdisp/elem_per_queue (default 2000) specifies the absolute number of requests in the queue.                          

Unit: percentage

Default value: 5

Integration

You should set this value quite small, as the dialog requests are also kept in this queue, and it is important that the queue does not become full.

Example

If you retain the default setting of 2000, the dialog queue can accept a maximum of 2000 requests. If you set rdisp/rfc_max_queue to 1 and the queue already contains 20 entries when a new RFC request comes in, the request is rejected.
