Websphere MQ

IBM MQ is a family of message-oriented middleware products that IBM launched in December 1993. It was originally called MQSeries, and was renamed WebSphere MQ in 2002 to join the suite of WebSphere products. In April 2014, it was renamed IBM MQ. The products that are included in the MQ family are IBM MQ, IBM MQ Advanced, IBM MQ Appliance, IBM MQ for z/OS, and IBM MQ on IBM Cloud.

MQ allows independent and potentially non-concurrent applications on a distributed system to securely communicate with each other, using messages. MQ is available on a large number of platforms (both IBM and non-IBM), including z/OS (mainframe), OS/400 (IBM System i or AS/400), Transaction Processing Facility, UNIX (AIX, HP-UX, Solaris), HP NonStop, OpenVMS, Linux, and Microsoft Windows.

IBM WebSphere MQ – Common install/uninstall issues for MQ Version on Windows - Middleware News

Creating a log file when you install or uninstall WebSphere MQ WebSphere MQ for Windows is installed using the Microsoft Installer (MSI). If you install the MQ server or client through launchpad , MQPARMS or setup.exe , then a log file is automatically generated in %temp% during installation. Alternatively you can supply parameters on the installation MSI command msiexec to generate a log file, or enable MSI logging system-wide (which generates MSI logs for all install and uninstall operations). If you uninstall through the Windows Add/Remove programs option, no log file is generated.
