---------------------------------------------------
Thank you all for your suggestions. I tried configuring a load balancer
worker; however, I'm getting HTTP 500 messages--Internal Server Error. I
reviewed the reference page; however, apparently, I'm missing something. Also
in the mod_jk.log, there's an error stating: "Could not find worker with name
'instance2' in uri map post processing". Any ideas? Thank you...
On the apache server in httpd.conf, I changed the JKMount statements because I
wanted to access all content.
Listen 80
.
.
.
LoadModule jk_module modules/mod_jk.so
#
JkWorkersFile conf/workers.properties
JkMount /* instance1
JkMount /* instance2
In workers.properties, added the load balancer information; it reflects the
following:
worker.balance1.type=lb
worker.balance1.balance_workers=instance1, instance2
#
worker.instance1.port=8009
worker.instance1.host=server.xxxx.com
worker.instance1.type=ajp13
#
worker.instance2.port=7009
worker.instance2.host=server.xxxx.com
worker.instance2.type=ajp13
On the tomcat server (which is the same server), I added the jvmRoute setting
in server.xml. For instance one, I added:
<Engine name="Catalina" defaultHost="localhost" jvmRoute="instance1">
For instance two, I added: <Engine name="Catalina" defaultHost="localhost"
jvmRoute="instance2">
