This attribute specifies the maximum number of Subprocesos de Arbortext PE that the Queued Transaction Scheduler can use to execute queued transactions. By default, this parameter is set to -1, meaning that every Subproceso de Arbortext PE in the pool can be allocated to the Queued Transaction Scheduler. If this attribute is set to 0, then no Subprocesos de Arbortext PE in the pool will ever be allocated to the Queued Transaction Scheduler. You can set maxConcurrentQueuedTransactions to 0 to dedicate the Subproceso de Arbortext PE pool to processing only immediate transactions.
