[Building Sakai] Issue with Sakai Instances Load Balances.

[Shoaib Chaudhary]

Hi,

Many thanks for your reply.

I have tried the code you told me and I also have tried to test mod_proxy
for this this time my main page (gateway) start refreshing countinously.
Unable to determine what is the problem.

I am following this page.

https://confluence.sakaiproject.org/display/DOC/Sakai+Admin+Guide+-+Advanced+Tomcat++%28and+Apache%29+Configuration

I have added this to my httd.conf


ProxyPass / balancer://sakaiCluster/ stickysession=JSESSIONID nofailover=On
<Proxy balancer://sakaiCluster>
BalancerMember ajp://localhost:8009
BalancerMember ajp://192.168.1.5:8009
</Proxy>

and added
inactiveInterval at org.sakaiproject.tool.api.SessionManager=5000
expired at org.sakaiproject.cluster.api.ClusterService=5000
ghostingPercent at org.sakaiproject.cluster.api.ClusterService=5000
refresh at org.sakaiproject.cluster.api.ClusterService=5000

to my sakai.properties file

please let me know where I am doing wrong.
