segmentation fault with nofailover=On and proxy in virtual host --------------------------------------------------------------- Key: MODCLUSTER-261 URL: https://issues.jboss.org/browse/MODCLUSTER-261 Project: mod_cluster Issue Type: Bug Affects Versions: 1.1.3.Final Environment: RHEL 5.7, Apache HTTPD 2.2.3 (packaged) or Apache HTTPD 2.2.21 (compiled), EAP 5.1.1 Reporter: Tomas Huryn Assignee: Jean-Frederic Clere Priority: Blocker we have - two clusters (2 JBoss instances for cluster1 (inst1 and inst2), 1 JBoss instance for cluster2 (inst3)). All instances run on the same machine (as) with binding manager - AJP on JBoss (port 8009 (inst1), 8109 (inst2), 8209 (inst3)) - root context enabled, application is in ROOT.war - defined jvmRoute in server.xml (inst1 -Djboss.web.jvmRoute=as.jb1 , inst2 -Djboss.web.jvmRoute=as.jb2 , inst3 -Djboss.web.jvmRoute=as.cms1) - Apache HTTPD runs on separate machine (ws) we need - cluster1 has connection to inst1 and inst2 with sticky session (client with one session will be routed to one instance only) - cluster2 has connection to inst3 We had tryed 2 solutions with no success: SOLUTION 1 - all in virtual host <VirtualHost externalip:8080> ServerName web1 <Proxy balancer://cluster1/> Order deny,allow Allow from all BalancerMember ajp://as:8009/ route=as.jb1 BalancerMember ajp://as:8109/ route=as.jb2 </Proxy> ProxyPass / balancer://cluster1/ stickysession=JSESSIONID|jsessionid nofailover=On ProxyPassReverse / balancer://cluster1/ </VirtualHost> <VirtualHost externalip:8080> ServerName web2 <Proxy balancer://cluster2/> Order deny,allow Allow from all BalancerMember ajp://as:8209/ route=as.cms1 </Proxy> ProxyPass / balancer://cluster2/ stickysession=JSESSIONID|jsessionid nofailover=On ProxyPassReverse / balancer://cluster2/ </VirtualHost> Result: Solution generate segmentation fault in error log, where somebody try to browse web. If we remove nofailover=On, all works fine except stick session - requests are splited to inst1 and inst2. SOLUTION2 - apache wide configuration <Proxy balancer://cluster1/> Order deny,allow Allow from all BalancerMember ajp://as:8009/ route=as.jb1 BalancerMember ajp://as:8109/ route=as.jb2 </Proxy> <Proxy balancer://cluster2/> Order deny,allow Allow from all BalancerMember ajp://as:8209/ route=as.cms1 </Proxy> <VirtualHost externalip:8080> ServerName web1 ProxyPass / balancer://cluster1/ stickysession=JSESSIONID|jsessionid nofailover=On ProxyPassReverse / balancer://cluster1/ </VirtualHost> <VirtualHost externalip:8080> ServerName web2 ProxyPass / balancer://cluster2/ stickysession=JSESSIONID|jsessionid nofailover=On ProxyPassReverse / balancer://cluster2/ </VirtualHost> Result: Sticky session works fine (no segmentation fault), but requests for web1 is routed to inst3 (cluster2) too and requests for web2 is routed to inst1 (cluster1) too. So there is problem with existence of two proxy cluster conffiguration directive. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (MODCLUSTER-246) :read-attribute and :write-attribute Error in AS7

by Stefan Negrea (JIRA)

:read-attribute and :write-attribute Error in AS7 ------------------------------------------------- Key: MODCLUSTER-246 URL: https://issues.jboss.org/browse/MODCLUSTER-246 Project: mod_cluster Issue Type: Bug Affects Versions: 1.1.3.Final Reporter: Stefan Negrea Assignee: Jean-Frederic Clere :read-attribute(name=xyz) and :write-attribute(name=xyz,value=zyx) do not work in console with JBoss AS7.1 nightly builds. The expectation is that :read-attribute will return the current value of the property or the default value if the property has not been set. For :write-attribute the expectation is that all the properties listed in :read-resource-description can be set. The JBoss was started with the following command: bin/standalone.sh --server-config=standalone-ha.xml Here is the current output for invoking the two operations use the advertise attribute as an example. The outcome of both operations is failed. [standalone@localhost:9999 subsystem=modcluster] :read-attribute(name=advertise) { "outcome" => "failed", "failure-description" => "No known attribute advertise", "rolled-back" => true } [standalone@localhost:9999 subsystem=modcluster] :write-attribute(name=advertise,value=true) { "outcome" => "failed", "failure-description" => "No known attribute called advertise", "rolled-back" => true } -- This message is automatically generated by JIRA.

This value should be at least doubled to 80 for use with ESB which creates long context names. -- This message is automatically generated by JIRA.
