IBM webMethods Integration Server allows you to create and run multiple instances of the server on one machine. When you install IBM webMethods Integration Server, you specify a name for the initial instance. The default name of the initial instance is “default”. The IBM installer creates the instance under the Software AG_directory\IntegrationServer\instances directory. You can create additional instances of Integration Server using the scripts provided by Integration Server or through IBM webMethods Command Central.

Each instance has a home directory under Software AG_directory\IntegrationServer\instances that contains its own packages, configuration files, log files, and updates. You administer and apply packages and updates to each Integration Server instance separately. You can apply the latest fixes using the IBM webMethods Update Manager.

The Software AG_directory\IntegrationServer directory is the parent directory for all server instances you create. It contains common and shared files that all server instances use, such as common jar files and fixes. For information about creating and running multiple Integration Server instances, see Running Multiple Integration Server Instances.
