In order to spread the workload, BladeLogic offers the ability to run multiple application servers in parallel. This means for instance that one server can be used to handle interactive user sessions, while other servers can be dedicated to running jobs. This mechanism can be implemented by installing the Application Server on multiple physical machines, but also by running multiple instances of the Application Server on one machine.
How could we do it.
Means how can we create multiple instances of Application Server on one machine....
From the blasadmin command line you can use the ‘create’ command.
From the gui, go into ‘configuration | infrastructure management’ under one of the application server launchers you can add more instances.
What arch is your appserver and how much memory is in it?
