Start and stop objects and services

Before we can create objects for a queue manager, the queue manager must be running. Similarly, before an application can send messages through a channel, the channel must be running and the receiving queue manager must have a running listener. In addition, any services like channel initiators and trigger monitors must be running if they are needed.

• Start and stop a queue manager
  We can start or stop an individual queue manager, or start or stop all the queue managers in a queue manager set.
• Start and stop a channel
  The way in which a channel is started depends on whether it is a caller channel or a responder channel. When you stop a channel, we can choose whether to stop the channel after the current batch of messages has finished processing, or force the channel to shut down before the current message batch has finished processing.
• Start and stop a listener
  Each listener object in IBM MQ Explorer represents a listener process; when you start the listener object in IBM MQ Explorer, the listener process starts.
• Start and stop a command server
  To connect to a queue manager from IBM MQ Explorer, the queue manager command server must be running.
• Start and stop a custom service
  We can configure a custom service to start automatically when the queue manager starts. We can also start or stop a service manually.
• Starting a trigger monitor
  To start a trigger monitor, we must first create a service that will start the trigger monitor.
• Starting a channel initiator
  To start a channel initiator, we must first create a service that will start the channel initiator.
