OBIEE 11g Multiple instance hitting Presentation catalog in round robin fashion

Hi All,


Our requirement was to have two instances of OBIEE 11g in a single box ie one for Dev and one for TEST

For OBIEE 10g, i see lot of information, but for OBIEE 11g i dont see any information on this..


Has anyone tried implementing multiple instances in OBIEE 11g through vertical clustering.?


so far i did vertical clustering of Presentation servers



1 BI Server

2 Presentation Servers

2 Presentation Services Plug-in ( analytics.ear, analytics2.ear)


The issue that i am facing is that the below analytics link sometimes hits one catalog and sometimes other catalog... ( its random hitting) [looks like Load balancer is acting here] 


Also i read on Rittman Blog that ..


"Presentation Services plug-in and Presentation Services have been decoupled. So, essentially a single web server can communicate to multiple presentation services in a round-robin fashion without the need for load balancer in vertical clustering. In horizontal clustering with multiple machines, load balancer will be required though in order to switch between different HTTP servers based on the incoming load. "


Any ideas how to switch off the load balancer?
