Installation configuration file, mqinst.ini

UNIX and Linux systems

The installation configuration file, mqinst.ini, contains information about all the IBM® WebSphere® MQ installations on a UNIX or Linux® system.

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

This file must not be edited or referenced directly since its format is not fixed, and could change. Instead, use the following commands to create, delete, query, and modify, the values in the mqinst.ini file:

crtmqinst to create entries.
dltmqinst to delete entries.
dspmqinst to display entries.
setmqinst to set entries.

The installation identifier, for internal use only, is set automatically and must not be changed.

Windows systems

Installation configuration information is held in the following key on Windows systems:

HKLM\SOFTWARE\IBM\WebSphere MQ\Installation\<InstallationName>

This key must not be edited or referenced directly since its format is not fixed, and could change. Instead, use the following commands to query, and modify, the values in the registry:

dspmqinst to display entries.
setmqinst to set entries.

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.
