Dear,
How is the loadbalancing done between one mobile server and two BI servers (CMS) ?

Hi Steven,
CMS clustering and also Mobile server could have seperate instances with a load balancer(Hardware or software load balancer) sending traffic to the required Mobile Server. From Mobile Server i mean the application server, this is nothing but load balacning traffic to Application Server instances.

If you have single mobile server (webapp) , what's the point of having Load balancer in front ?
When user accesses mobile server, which is a webapp on a webapp server that web app makes a call to BOE (CMS), initially its a call to one CMS, because I don't think mobile webapp supports @cluster - however, BOE Platform decides which CMS will handle the call based on its own rules.
So, if you have CMS 1 and CMS 2, webapp makes call to CMS 1 - the processing of that session might still end up on CMS 2.
You can't control or configure load balancing between CMS servers. Its handled internally.
You can only control load balancing between webapp servers.
Your request to the server would fail as only one CMS serving your requests would be down.
This is similar to how in BI launch pad portal if you specify CMS as cluster
you would be allowed to login if any CMS in the cluster is up and running. If you dont specify the cluster but the CMS your request would fail if the CMS is down.

Even if CMS2 isn't defined on the mobile server?
I would suppose you can specify connectionName.BOBJ_MOBILE_CMS=@BOCLUSTER. It is mentioned in the manual.
But don't find where you can define then the @BOCLUSTER on the mobile server.
Or you need to define two connections in the server.properties file one to every CMS server?

server.properties file is within the MOBIServer war file deployed location within the Application server.
Example as below:-
C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps\MOBIServer\WEB-INF\config
If you are customizing the file then it should be placed from the "default" location to "custom" within config folder. This ensures that when you redeploy the MOBIServer war file using the Wdeploy tool or a upgrade installation is done it takes care to back up your customization.
