Apache Load balancer

Clustering involves:

• 1separate apaches on each slave


• 1separate slave servermanagers with one single master persistance storage server manager


• tomcatsintegrated in the foreground method server.

you will need a load balancer from Cisco, A10 or Barracuda. A load balancer is a switch that has an alias of your web server name ofapplication URL (http://master.com/Windchill) then redirects your users to the 3 separate apachesweb server names like (http://slave1.com/Windchill), ...

Are you doing this for the first time?

You can then configure you load balance based on usage, ip addresses and so forth.

Good luck,

Hello Gurus,

I need to setup a cluster where I need to configure Master Apache as a loadbalancer. I have 4 slaves with 3 MS running n each slave.

Can somebody share how can this be achieved? I need the steps for configuration.

Thanks in advance

Hey Jess,

Yea, I corrected the message just after I sent it as you can see in the discussion. LOL. 1 apache per server (slave or master).

Mayur, as for the configuration file,Jess is right, theinstallation now in 10.X should haveyourWindchillwt.properties configured already. Are you talking about the load balancer configuration file.Those are different formats for each type of load balancer.

Why 3 separate Apaches on each slave? Did you mean 4 separate Apache's
-- one on each slave?

As for slave vs. master server managers in 10.2 you simply configure all
server managers the same way (much as one would have configured a slave
node in previous releases) -- and one automatically becomes the master
(both initially and upon any failure of the master).

And, yes, a Tomcat is integrated into each foreground method server.

As you suggest, the recommended approach to cluster-level balancing is a
hardware load balancer.
