Hi,

i have the following situation

Apache is balancing requests to backend JBoss Server . Everything (the 
balancing of requests to the webcontainer (tomcat) of jboss)works fine - except 
i cannot get the balancer-manager working.

Of course the GUI appears but after clicking on a worker link nothing happens.

Apache 2.2.3 on Suse Linux Enterprise Version 10

<Proxy balancer://portal>
        Order deny,allow
        Allow from all
        BalancerMember ajp://lx-tpor01.xxxx.xxxxxxx.xx:8009/portal route=jboss11
        BalancerMember ajp://lx-tpor01.xxxx.xxxxxxx.xx:18009/portal 
route=jboss12
    and so on.......
</Proxy>

ProxyPass /portal balancer://portal stickysession=JSESSIONID 
lbmethod=byrequests nofailover=Off


ProxyPass /balancer-manager !
<Location /balancer-manager>
        SetHandler balancer-manager
        Order Deny,Allow
        Deny from all
        Allow from xxxxxx
</Location>

I got the follwing gui

LoadBalancer Status for balancer://portal
StickySession Timeout FailoverAttempts Method JSESSIONID 0 7 byrequests

Worker URL Route RouteRedir Factor Status
ajp://lx-tpor01.xxxx.xxxxxxx.xx:8009/portal jboss11  1 Ok
ajp://lx-tpor01.xxxx.xxxxxxx.xx:18009/portal jboss12  1 Ok

and so on

but if i disable one Jboss instance the status remains on ok, and if i click on 
a worker url i don't get the possibility to edit the attribute - only the url 
is changing without any change in the gui.
also when i click on the balancer nothing happens.

i appreciate any help - thanxs in advance

I just tried it with httpd 2.2.8 and it works for me. Although there seeems to be no fit in the httpd changelog, 2.2.3 is a little early in the 2.2.x release cycle and the balancer and balancer manager were new in 2.2.x, so if nothing else helps, upgrading to a more recent 2.2.x (like 2.2.8 or 2.2.9 expected in a few weeks) would be worth trying. I think I remember having it used with 2.2.6, but I didn't try it with 2.2.3 or earlier.

Others?

Apart from that: the httpd users list might be a better place to ask, because this seems not to be related to some difficult AJP13 stuff instead it seems to be a more general httpd mod_proxy_* issue.

Regards und Grüße nach Wien
