[Building Sakai] Issue with Sakai Instances Load Balances.

[Anand Mehta]

Hello Shoaib,

Please check the serverID, serverURL and serverName in sakai/local.properties 
and make sure they are correct. Also check the following settings and see if 
tweaking them helps:

inactiveInterval at org.sakaiproject.tool.api.SessionManager
expired at org.sakaiproject.cluster.api.ClusterService
ghostingPercent at org.sakaiproject.cluster.api.ClusterService
refresh at org.sakaiproject.cluster.api.ClusterService

The attached file contains an example of worker settings in a cluster, so you 
can try those as well. I noticed that you have set lbfactor for tomcat3 to 9. Is 
that a typo?

You can find more information about clustering here: 
https://confluence.sakaiproject.org/display/DOC/Configuring+Clustered+Sakai+Installations



 Thanks,
Anand

Subject: [Building Sakai] Issue with Sakai Instances Load Balances.

Hello, 

I am trying to load balance to Sakai  instances 

I have attached my worker file with this email. 

I also have added jvm route as following 

I am  facing following problem

Enginename="Catalina"defaultHost="localhost"jvmRoute="tomcat2"
Enginename="Catalina"defaultHost="localhost"jvmRoute="tomcat3"

When   i log in to Sakai using my log in ID and password it first log in, show  
me logged in screen and my course for a while and again take me back on  welcome 
screen /portal where I see the main page of Sakai again.

As  per my understanding the instances are not able to maintain sessions. I  
don't if I am right or wrong. 


Can some one help me out please.
