Hi Guys
This seems unusal. Also please excuse me for starting a new thread. (I have searched throughly in past discussions and nobody has answered this question satisfactorily)
I'm try to use Apache Http server 2.0 as loadbalancer for 2 instances of Tomcat 5.0.
Now somehow all the requests appear to go to only 1 instance of TomCat 5.0(port 12009 my guess its overriding 11009) when I specify a common webapp location (I mean webapp1) to both the instances...However when i specify 2 different locations it works with tomcat1(11009) handling all webapp1 reuests while tomcat2(12009) handling all webapp2 requests.
My httpd.conf in apache 2.0 looks like this:
LoadModule jk2_module modules/mod_jk2.dll
<Location "/webapp1">
JkUriSet worker ajp13:localhost:11009
</Location>
<Location "/webapp2">
JkUriSet worker ajp13:localhost:12009
</Location>
My worker2.properties in apache 2.0 looks like this:
worker.list= ajp13:localhost:11009, ajp13:localhost:12009
#socket channel
[channel.socket:localhost:11009]
port=11009
host=127.0.0.1
#worker for the connector
[ajp13:localhost:11009]
channel=channel.socket:localhost:11009
worker.ajp13:localhost:11009.lbfactor=1
#socket channel
[channel.socket:localhost:12009]
port=12009
host=127.0.0.1
#worker for the connector
[ajp13:localhost:12009]
channel=channel.socket:localhost:12009
worker.ajp13:localhost:12009.lbfactor=1
Now my questions are:
1> What changes do I need to make either in httpd.conf or worker2.properties to enable load-balancing?
2> Since it works for 2 different web applications I'm sure there's a minor syntactical error in either of 2 configurations
3> could any of you help me with this... Please I'm really frustrated trying to fix this...
4> Also my error.log file looks like this:
How to fix the error...
error.log:
[Sat Apr 10 02:57:51 2004] [notice] Parent: Created child process 3584
[Sat Apr 10 02:57:52 2004] [notice] Child 3584: Child process is running

Thanks in advance
Ravi

Hi Guys
Finally figured it out... These links are useful for getting the Apache 2.0 and Tomcat 5.0 to work:
This one explains on connecting Apache2.0 to Tomcat 5.0 via mod_jk2

And This link explains on How to setup Apache HttpServer as a Loadbalancer for Tomcat 5.0 instances:
