Re: Bug or Feature inside mod_jk loadbalancer algo?

2005-09-16 Thread Peter Rossbach

Sounds good to me.

Wrote a spec before implementation is very helpfull :-)

The domain case with sticky session and real clustered szenarios  is  
not easy.

Hi guys,

Peter you are correct about this...
I found by myself too, that balancer is misbehaving in some cases.
One of them is 'domain' model, where multiple workers should behave
like one on the global scale, but still maintain internal load.

The other is for worker-like mpm's when cachesize is lower then
the ThreadsPerChild. I've been able to fix that (sort of), but I'm
not happy with the fix.

What would I suggest is that we gather all the 'use cases' and
write down what the predicted results should be.

I'll create a separate .txt file (that will later be part of
loadbalancer howto) upon which we can enter the configuration
and expected behavior.

How that sounds?

I'm moving this discussion to the tomcat-dev@, so that we have the
trace of it. OK?

Regards,
Mladen.
