Use the mqsireload command to request the broker to stop and restart execution groups.
When you issue this command, a message is sent to the broker, which stops and restarts all its execution groups. You can specify a single execution group to be reloaded, but you are recommended to use the default form of this command to reload all execution groups.
Because an execution group does not stop until all message flows within it terminates, the ability of the broker to reload quickly depends on the processing time for the longest running message flow. This affects the performance of this command, and you are recommended to review any long-running message flows.
If you have included a user-defined node or parser within a message flow on the broker, these are deleted by this command, and the relevant termination functions called. When message flows are restarted, the resources used by user-defined nodes and parsers are re-accessed and reacquired. However, you are recommended to ensure that user-defined nodes and parsers provide their own mechanism to reload persistent state and data dynamically, and do not rely on the use of this command.
On Windows, Linux, and UNIX systems the user ID used to issue the command must be a member of the group mqbrkrs.
