Guidelines for Running Multiple Integration Server Instances on the Same Machine
The following guidelines apply to running two or more Integration Server instances on the same machine:
*The common libraries are located under SoftwareAG\common and Integration Server_directory \lib. The files in these libraries can be used by all server instances. For example, you can make custom jar files available to all server instances by placing them in the Integration Server_directory \lib\jars\custom directory.
*Updates and custom jars located at the instance level take precedence over the updates and custom jars located in the common libraries.
*Every port number on each server instance must be unique unless the host machine has more than one NIC. The ports include the primary port, diagnostic port, and all other ports described in Configuring Ports.
*You do not need an additional license to create and run multiple Integration Server instances. However, creating and running additional server instances will increase the number of concurrent processes. Before creating additional server instances, check your system resources and your Software AG license.
