Overview of Integration Server Instances
You can create and run multiple instances of Integration Server on the same host machine with a single physical installation of webMethods Integration Server. This is not the same as clustering, which is described in webMethods Integration Server Clustering Guide. When running multiple instances of Integration Server on the same host machine, each server has its own packages, configuration files, log files, and updates; however, unlike clustering, all of the server instances can share common libraries. Sharing the common library files reduces the amount of overhead and effort involved when installing fixes and patches on each server.
You manage each server instance separately using the Integration Server Administrator. You can also perform certain management, configuration, and monitoring tasks from a single location using Software AG Command Central. For information about using Software AG Command Central to manage Integration Server instances, see the Command Central documentation.
