Multiple installations of Version 7.1, or later
We can choose to have one of the IBM WebSphere MQ Version 7.1 installations configured as the primary installation. Your choice depends on how applications locate libraries.
The IBM MQ libraries, such as mqm, which ship with IBM WebSphere MQ Version 7.1 automatically use libraries of the level required by the queue manager to which they are connecting. This means that provided an application locates its IBM MQ libraries from a IBM WebSphere MQ Version 7.1 installation, it can connect to any queue manager on that system. Having one IBM WebSphere MQ Version 7.1 installation configured as primary ensures that if the application finds its IBM MQ interface library, the application can connect to any queue manager.
For more information about connecting applications in a multiple installation environment, see Connect applications in a multiple installation environment.
The primary installation is not automatically changed when you uninstall the primary installation. If we want another installation to be the primary installation, we must manually set the primary installation using the setmqinst command. For more information, see Uninstalling, upgrading, and maintaining the primary installation.
