EEM Script Load Balancing

Hi

I have noticed EEM script is running only on specific application server, even though i have used webdisp host to login to server. So i can see the script launch webdisp host to logon. but when performing the steps it is running on same application server every time, and  i suspect this is due to steps captured in recording.

Please let me know how i can achieve the load balancing in the script and their steps.

Is this can be done by editing the script ?

Highly appreciated the inputs.

Thanks

Dominic
