This chapter explains the parameters that can be configured for JMS storage objects of type ‘Queue’. In general, these parameters are the most common ones used in the Point-to-Point (PTP) model of JMS and they can be configured in the default profile at the node FioranoMQ->Fiorano->mq->ptp->Queues->specific queue through Offline configuration using Studio.
-
For information on how to configure the FioranoMQ Server in Offline mode, refer to the Offline Configuration Through Profile Manager section
-
For Online Configuration (through the Web Management Console), refer to the FioranoMQ Web Management Console section.
From FioranoMQ 9.1.0 release onwards, a unique Destination Level Configuration support is included. For more on this, please refer to the Support for Destination Level Configuration section.
