When a queue manager is running, you see some or all of the following batch jobs running under the QMQM user profile in the WebSphere MQ subsystem. The jobs are described briefly in Table 1, to help you decide how to prioritize them.
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 that 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 that is the first job started by the queue manager. It deals with MQCONN requests, and starts agent processes to process WebSphere MQ API calls |
AMQZMGR0 | Process controller. This job is used to start up and manage listeners and services. |
AMQZMUC0 | Utility manager. This job executes critical queue manager utilities, for example the journal chain manager. |
AMQZMUR0 | Utility manager. This job executes critical queue manager utilities, for example 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 |
Note:
The LU62 receiver job
runs in the communications subsystem and takes its run-time properties from
the routing and communications entries that are used to start the job. See WebSphere MQ Intercommunication for more details. |
You can view all jobs connected to a queue manager, except listeners (which do not connect), using option 22 on the Work with Queue Manager (WRKMQM) panel. You can view listeners using the WRKMQMLSR command.
