Description of MQ tasks :

When a queue manager is running, you see some or all of the following batch jobs running under the QMQM user profile in the MQ subsystem.
Job name Function AMQALMPX The checkpoint processor that periodically takes journal checkpoints. AMQCLMAA Non-threaded TCP/IP listener. AMQCRSTA TCP/IP-invoked channel responder. AMQCRS6B LU62 receiver channel and client connection (see note). AMQFCXBA Broker worker job. AMQPCSEA PCF command processor. Handles PCF and remote administration requests. AMQRMPPA Channel process pooling job. AMQRRMFA Repository manager for clusters. AMQZDMAA Deferred message handler. AMQZFUMA Object authority manager (OAM). AMQZLAA0 Queue manager agents that perform the bulk of the work for applications that connect to the queue manager using MQCNO_STANDARD_BINDING. AMQZLAS0

Queue manager agent. AMQZXMA0 The execution controller is the first job started by the queue manager. Deals with MQCONN requests. Starts agent processes to process MQ API calls. AMQZMGR0 Process controller. Used to start up and manage listeners and services. AMQZMUC0 Utility manager. Do critical utilities, as the journal chain manager. AMQZMUR0 Utility manager. Do critical utilities, as the journal chain manager. RUNMQBRK Broker control job. RUNMQCHI The channel initiator. RUNMQCHL Sender channel job that is started for each sender channel. RUNMQDLQ Dead letter queue handler. RUNMQLSR Threaded TCP/IP listener. RUNMQTRM Trigger monitor.
