The is a type of work queue that uses a number of worker threads that watch a queue and pick up an operation to process whenever one becomes available. The traditional work queue is named that because its implementation is similar to that used by the Sun Java System Directory Server. The traditional work queue is a FIFO queue serviced by a fixed number of worker threads. However, there are a couple of notable differences in its design: 1) The number of worker threads is fixed, but it can be changed on the fly and those changes take effect immediately. In the Sun Java System Directory Server, changes to the number of worker threads require a server restart to take effect. 2) The work queue in the Sun Java System Directory Server is unbounded. If all threads are busy processing existing operations and new requests arrive, they continue to accumulate in the work queue and the server appears to be frozen. In the OpenDS Directory Server, it is possible to place a size limit on the work queue. When this number of operations are in the queue, waiting to be picked up by threads, any new requests received are rejected with an error message. ds-cfg-traditional-work-queue ds-cfg-work-queue org.opends.server.extensions.TraditionalWorkQueue Specifies the number of worker threads to be used for processing operations placed in the queue. If the value is increased, the additional worker threads are created immediately. If the value is reduced, the appropriate number of threads are destroyed as operations complete processing. ds-cfg-num-worker-threads Specifies the maximum number of queued operations that can be in the work queue at any given time. If the work queue is already full and additional requests are received by the server, the requests are rejected. A value of zero indicates that there is no limit to the size of the queue. The work queue does not impose any limit on the number of operations that can be enqueued at any one time. ds-cfg-max-work-queue-capacity
