> ManagerBalancerName variable is lowercased
> ------------------------------------------
>
> Key: MODCLUSTER-540
> URL: https://issues.jboss.org/browse/MODCLUSTER-540
> Project: mod_cluster
> Issue Type: Bug
> Affects Versions: 1.3.3.Final
> Reporter: Bogdan Sikora
> Assignee: Michal Karm Babacek
>
> Documentation
> {noformat}
> 3.5.8. ManagerBalancerName
> ManagerBalancerName: That is the name of balancer to use when the JBoss AS/JBossWeb/Tomcat doesn't provide a balancer name.
> Default: mycluster
> {noformat}
> Issue:
> Apache Httpd (2.4.23-ER1) did not recognize ManagerBalancerName uppercase letters and is turning whole name to lowercase. If worker passes balancer name then is correctly used as documentation suggest and even with uppercase letters.
> Reproduce:
> 1. Set up balancer (httpd) with worker (for example EAP-7, do not set Balancer variable)
> 2. Set ManagerBalancerName to QA-bAlAnCeR in mod_cluster.conf
> 3. Start everything and access mod_cluster status page
> 4. Look for Balancer variable under your worker, should be cAmeLcAse but isn't
> Workaround:
> Set balancer name in each worker, as documentation says it will override variable set in mod_cluster.conf (ManagerBalancerName)
> Verbose:
> Httpd debug node join part
