Integer (outstanding-requests)
1
Purpose
The QueueDepthLimit parameter specifies the number of outstanding requests that can be queued before an additional ODBC worker application is started. When this limit is exceeded for a time specified by the QueueDepthLimitTimeout parameter, an additional ODBC worker application is started unless this causes the number of workers to exceed the value specified in the MaxWorkers parameter.
The process of starting up additional workers depends on at least one of the existing workers being idle. This means that you need to configure an extra worker that can respond to management events when the other workers are busy. In practical terms, this means setting MinWorkers = QueueDepthLimit + 1.
