How/where to set 'maxAttempts' ?

[nichele]

Hi All,

with proxy_balancer i'm able to set 'maxAttempts' value using:

<Proxy balancer://mycluster>

       BalancerMember ajp://xxxxx:8009/ route=NODE01

       BalancerMember ajp://yyyyy:8009/ route=NODE02

       BalancerMember ajp://www:8009/ route=NODE03

       BalancerMember ajp://zzzzz:8009/ route=NODE04

       ProxySet lbmethod=bybusyness

       ProxySet stickysession=JSESSIONID|jsessionid

       ProxySet maxattempts=2

</Proxy>

and by default it's set to number of members - 1 (see http://httpd.apache.org/docs/2.1/mod/mod_proxy.html)

Some questions about that:

- Is it set to the same default value using mod_cluster ? (from the doc it seems set to 1 by default)

- How to change that value ? (i saw something in the doc but i don't  understand....)

What's the meaning of Maxtry in the cluster manager ui ?

For instace i have:

balancer: [1] Name: mycluster Sticky: 1 [JSESSIONID]/[jsessionid] remove: 0 force: 1 Timeout: 0 Maxtry: 1

THanks a lot in advance

you can't do that using proxy_balancer only mod_cluster allows that. It must be configurated in the jboss side.

Hi Jean-Frederic,

at the end i have found i can set maxAttemps in server.xml file (since i'm using tomcat)  as Listener property.

"Maxtry" in the cluster-manager interface reflects that value, but i'm not sure about the meaning ....is it the maxAttempts property describe in page 62 - sect. 14.2 Balancer ? On the doc the default value should be 3 but to me was set to 1....am i missing anything ?

I'm also a bit surprise to have to set that value "worker" side since to me is a "proxy" property more than a "worker" property (in other words, in this way i can  set that property to different values - since i have different workers - and it seeems at the end, the used one is the lastest comunicated by the lastest  worker.

Thanks and sorry if the message is not so clear...

"Maxtry" in the cluster-manager is maxAttempts and the default value is 1. I have ajust code and docs to prevent confusion.

mod_cluster idea is to configure most things on the workers side to allow dynamic configurations.
