----------------------------------------
Summary: [Mod_cluster] ManagerBalancerName variable is lowercased
Key: MODCLUSTER-541
URL: https://issues.jboss.org/browse/MODCLUSTER-541
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
