Tomcat Load Balancing

[Gad B <Ga...@spark.com>]

Hi All,
I am struggling with Load Balancing and Tomcat 3.1. I got Tomcat on 2
machines and a configuration file
for Apache JServ to balance requests between the two.
 
############# from tomcat.conf (included in httpd.conf) ###############
ApJServMount /servlet balance://spark1/servlet 
  
ApJServBalance spark1 PC1 
ApJServBalance spark1 PC2 

ApJServHost PC1 ajpv12://mymachine1:8007 
ApJServHost PC2 ajpv12://mymachine2:8007 

ApJServRoute JS1 PC1 
ApJServRoute JS2 PC2 

############# from tomcat.conf (included in httpd.conf) ###############

Gad,

I see you don't have a shared memory file defined:
ApJServShmFile logs/jserv_shm 
And you do not have a zone defined
ApJServMount /servlet balance://set1/zone1.

Also you have used the default port 8007 on both machines. It could be your using the default port on machine in stead of the load balancing port.
Try using another port than 8007 and check the mod_jserv.log if you are using the load balancing.
Good luck Xander

  From the documentation I gather that this is all I need to define. I started tomcat on both machines
  and apache is running on mymachine1.
  My problem is that everything works only with mymachine1. mymachine2 never gets any requests. 
   
  Is there anyone on the list who has done load-balancing with Tomcat 3.1? If so, I would appreciate 
  any advice on the subject.
   
  Thanks,
  Gad
