Jk2 compiling problem sorted ..Do you know.. How?
Hi Dale and Igor
Thanks for helping me out. At last we sorted our jk2 connector compilation.
There was a problem with our "Make" command that came with solaris2.8. I
have down loaded latest and it worked smoothly.
Now web application (in tomcat) availability is the problem! While tomcat is
still loading, mod_jk directs the calls to tomcat and web-app is not ready
yet. I see this is a missing feature from ajp13 (documented some where).
Any clues on sorting this problem alternately?
Cheers
Bhaskar

Just a quick post to say thanks, we went live using pen and 3 clustered
instances of 5.0.25 today and its working a treat. Load is spread almost
perfectly. The only feature I would have as a "nice to have" would be to
apply wieghtings to the target hosts but other than that spot on and no
problems whatsoever so far.

Thanks for the quick reply.
So the supplied tomcat load balancer isnt of any use for stateful sessions
where the cluster is spread accross several machines?

to paraphrase, you want to have it look like the same machine to the browser
(ie user).
the easiest way is to use a hardware load balancer. I've use this approach a
couple times in the past and it works well.

Hi,
I'm currently testing a setup up on 3 machines.
2 have tomcat 5.0.19, these 2 are clustered with session replication and
have a simple test app.
The other, also 5.0.19, runs the supplied balancer app.
I've written a simple round robin rule which passes the requests back and
forth as it should, I can see the sessions being
replicated fine in the logs so all is ok there.
BUT my problem is accessing the same session on both machines. Basically I'm
stumped, I know its not accessing the same session
because the redirected URL is different but how can I get around this?
I've tried a using an HTML frame on the balancer machine but that was
clutching at straws and obviously didnt work.
Any ideas would be appreciated.

Which is an event not trivial to catch. I know of hacks, like tailing
"catalina.out" log and seeing when the "last of the Mohicans" has
loaded, but, again, it is not trivial to catch. Or better said, it is
particualr to each setup. You would have to tailor your own hacks.
I wish there was a way to query Tomcat and see if it loaded ALL it's
stuff. Or at least the engine... Could we trail logs for that?
Nix.
