question on jvmRoute parameter (tomcat version 5.0.28)

[Rumpa Giri <gi...@yahoo.com>]

According to the 5.0 docs, the jvmRoute description says the following:

"Identifier which must be used in load balancing scenarios to enable         session affinity. The indetifier, which must be unique across all         Tomcat 5 servers which participate in the cluster, will be appended to         the generated session identifier, therefore allowing the front end         proxy to always forward a particular session to the same Tomcat 5         instance."

In the worker.properties(5.0) the worker_name correspond to the jvmRoute.

we specify the worker names who participate in the loadbalancing. such as

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=server1, server2, server3, server4, server5, server6, server7, server8, server9, server10, server11, server12
worker.loadbalancer.sticky_session=1
worker.loadbalancer.local_worker_only=1

when you say 

"which must be unique across all         Tomcat 5 servers which participate in the cluster" 

do you mean the all the worker names hence the jvmRoute should be unique?

Currently we have:

server1 through server4 is on one machine having 4 tomcat instances.
server5 through server8 is on one machine having 4 tomcat instances.
server9 through server12 is on one machine having 4 tomcat instances.

Thanks,

RE: question on jvmRoute parameter (tomcat version 5.0.28)

[Tim Lucia <ti...@yahoo.com>]

The set of worker names is one-to-one and onto the set of jvmRoutes.  I use
the short host name, an underscore and the port number (ajp), i.e.,

Tomcat1_9009
Tomcat2_10009
Tomcat3_11009
Tomcat4_12009

For the worker names and the jvm routes, thus making the identifiers unique,
and following the 1:1 and onto rule.
