OFBiz4.0 clustering,session replication, failover and load balancing - Howto

[vignesh sabapathi]

Hi OFBizers

After surfing the posts i could'nt find much info abt OFBiz4.0 clustering. Few members raised some issues in retaining shopping cart items during session replication. We are looking into that issue..

As an alternative i m posting here the way to do clustering and session replication in OFBiz4.0 by deploying OFBiz4.0 in external tomcat (By this way the shopping cart items can be retained)

Following are the steps to be done

step 1 : create a template (as same as for ofbiz9.0 deployment in tomcat)
step 2 : Deploy ofbiz in tomcat (i tried with tomcat 6.0.16)
step 3 : Cluster tomcat instances (i used 2 tomcat instances)
step 4:  Enable session replication by changing the configurations in server.xml file in all the nodes (use backup manager to retain cart items during session replication)
step 5 : Enable Apache with mod_jk support
step 6 : configure Apache (create worker.properties and change the configurations of httpd.conf and ssl.conf) to load balance tomcat servers
Step 7 : check all the functions are working with lamba probe tool

Hav a happy clustering

i wil try to upload a file detailing all the activities later on
