Change configuration information on UNIX, Linux, and Windows

On UNIX, Linux, and Windows, we can change the IBM MQ configuration attributes that are held in configuration files, at the level of the node and of the queue manager.

On UNIX, Linux, and Windows platforms, we can change IBM MQ configuration attributes within the following files:

Client configuration options are held separately, in the client configuration file(mqclient.ini).

A configuration file (or stanza file) contains one or more stanzas, which are groups of lines in the .ini file that together have a common function or define part of a system, such as log functions, channel functions, and installable services.

Because the IBM MQ configuration file is used to locate the data associated with queue managers, a nonexistent or incorrect configuration file can cause some or all MQSC commands to fail. Also, applications cannot connect to a queue manager that is not defined in the IBM MQ configuration file.

Important: Any changes you make to a configuration file usually do not take effect until the next time the queue manager is started.
