How to create a new instance (multiple instances) for webMethods Integration server?

We have Default Port instance 5555 to run the IS. I want to create 2 or more instances for the same Integration Server, so that i can run two instances at a time.

You cannot create multiple instances of same IS. After the IS start up, it will create an empty file (LOCKFILE) to make sure only one instance of IS is running.We can create multiple ports, but not instances.

First why do you need this?what is that you ate trying to do?you can have multiple instances running on a same server/physical host

I just want to perform load balancing test for my server. If need to use multiple server, i need to configure clustering. So i want to create multiple instances for the same server. How can we have multiple instances for the same server?

Try clustering option in the admin page
