Installation configuration file, mqinst.ini
On UNIX or Linux, the installation configuration file, mqinst.ini, contains information about all the IBM MQ installations. On Windows, installation configuration information is in the registry.
Location of the mqinst.ini file
The mqinst.ini file is in the /etc/opt/mqm directory on UNIX and Linux systems. It contains information about which installation, if any, is the primary installation as well as the following information for each installation:- The installation name
- The installation description
- The installation identifier
- The installation path
Important: The mqinst.ini file must not be edited or referenced directly since its format is not fixed, and could change.
The installation identifier, for internal use only, is set automatically and must not be changed.
Instead of editing the mqinst.inifile directly, we must use the following commands to create, delete, query, and modify, the values in the file:- crtmqinst to create entries.
- dltmqinst to delete entries.
- dspmqinst to display entries.
- setmqinst to set entries.

There is no mqinst.ini file on Windows. Installation configuration information is in the registry, and is held in the following key:
HKLM\SOFTWARE\IBM\WebSphere MQ\Installation\InstallationNameImportant: This key must not be edited or referenced directly since its format is not fixed, and could change. Instead, we must use the following commands to query, and modify, the values in the registry:
On Windows, the crtmqinst and dltmqinst commands are not available. The installation and uninstallation processes handle the creation and deletion of the required registry entries. Parent topic: Change configuration information on UNIX, Linux, and Windows
