Specifying maxConcurrentQueuedTransactions sets the maximum number of queued transactions that may be processed simultaneously by the Arbortext PE 子进程 pool.

There are two other possible values, -1 and 0.

If it’s set to -1, the default, there is no specified limit, and the Arbortext PE 子进程 pool will execute as many queued transactions as it can by keeping all Arbortext PE 子进程 busy.

If it’s set to 0, no queued transactions will be accepted by the Arbortext PE 子进程 pool, effectively reserving the entire pool for immediate transactions only. If you need to reserve a Sub-process pool for queued requests, refer to Specifying a Dedicated Queuing Pool.
