Registry changes created by installation and configuration
When you install WebSphere® Message Broker, the installation program creates a number of entries in a registry.
Runtime components
On Windows, the ALLUSERPROFILE environment variable is used; on Linux and UNIX systems, equivalent values are stored within the installation directory structure. On all platforms, the environment variable MQSI_REGISTRY is set to point to the exact location. Do not alter or remove these entries unless instructed to do so by your IBM® Service representative.
On Windows, some entries are also added to the system registry under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI (for 32-bit brokers on 32-bit operating system editions and 64-bit brokers on 64-bit operating system editions) or under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI (for 32-bit brokers on 64–bit operating system editions); these entries record the installed 32–bit database drivers for Oracle and Sybase, which contain driver locations and parameters.
A final entry is added under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\WebSphere Broker v*** for Event Log information, where v*** is the current three-digit product version number.
WebSphere Message Broker Toolkit
All registry entries are controlled by IBM Installation Manager. On Windows, the system registry is used; on Linux on x86, equivalent entries are stored in /var/ibm/InstallationManager/. Do not alter or remove these entries unless instructed to do so by your IBM Service representative.
The installation directory for Installation Manager is stored in HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Installation Manager (for 32–bit operating system editions) or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\IBM\Installation Manager (for 64–bit operating system editions), under the location value.
Uninstall keys are created for all products that are installed by Installation Manager under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Current\Version\Uninstall\IBM Installation Manager, under the name IM-packagegroupname where packagegroupname is the name of the package group in which the product is installed; for example, IBM Software Development Platform.
