Broker Administration

The Command utility (imqcmd) has added a subcommand and several options that allow administrators to quiesce the broker, to shutdown the broker after a specified interval, or to destroy a connection.

• Quiescing the broker moves it into a quiet state, which allows messages to be drained before the broker is shut down or restarted. No new connections can be created to a broker that is being quiesced. To quiesce the broker, enter a command like the following.

  imqcmd quiesce bkr -b Wolfgang:1756

• To shut down the broker after a specified interval, enter a command like the following. The time interval specifies the number of seconds to wait before the broker is shut down.

  imqcmd shutdown bkr -b Hastings:1066 -time 90

• To destroy a connection, enter a command like the following.

  imqcmd destroy cxn -n 2691475382197166336

  Use the command imqcmd list cxn or imqcmd query cxn to obtain the connection ID.
