By defining a common environment ID, multiple instances of MobileFirst Server are possible to be installed on the same server.
You can install multiple instances of MobileFirst Server administration service, MobileFirst Server live update service, and MobileFirst runtime on the same application server or WebSphere® Application Server cell. However, you must distinguish their installations with the JNDI variable: mfp.admin.environmentid, which is a variable of the administration service and of the runtime. The administration service manages only the runtimes that have the same environment identifier. As such, only the runtime components and the administration service that have the same value for mfp.admin.environmentid are considered as part of the same installation.
