Use the mqsistop command to stop an integration node.
The mqsistop command stops an integration node that is running. It does not stop any resources that are associated with the integration node, such as a queue manager.
On Linux and UNIX systems, all names are case-sensitive.
Specify this flag only if you have already tried, and failed, to stop the integration node in a controlled fashion by using the mqsistop command without the -i flag.
