Changing configuration information on Windows, UNIX and Linux systems
Configuration attributes are held in configuration files, at the level of the node and of the queue manager.
-
An IBM MQ configuration file ( mqs.ini ) to effect changes for IBM MQ on the node as a whole. There is one mqs.ini file for each node.
See Attributes for changing IBM MQ configuration information for more information on the stanzas included in mqs.ini.
- A queue manager configuration file ( qm.ini ) to effect changes for specific queue managers. There is one qm.ini file for each queue manager on the node.
See Changing queue manager configuration information for more information on the stanzas included in qm.ini.
Client configuration options are held separately, in the client configuration file.
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.
Any changes you make to a configuration file usually do not take effect until the next time the queue manager is started.
On Windows and Linux (x86 and x86-64 platforms) systems, you can edit configuration information from the MQ Explorer.
On Windows systems you can also use the the amqmdain command to edit the configuration files.
