TCP request queuing provides the ability to queue connection requests that exceed the capacity of connections for a pool, pool member, or node, as determined by the connection limit. Consequently, instead of dropping connection requests that exceed the capacity of a pool, pool member, or node, TCP request queuing makes it possible for those connection requests to reside within a queue in accordance with defined conditions until capacity becomes available.
When using session persistence, a request becomes queued when the pool member connection limit is reached.
Without session persistence, when all pool members have a specified connection limit, a request becomes queued when the total number of connection limits for all pool members is reached.
Conditions for queuing connection requests include:
Connection requests within the queue become dequeued when:
