[JBoss JIRA] Created: (MODCLUSTER-141) Use versioned docs

by Paul Ferraro (JIRA)

Use versioned docs ------------------ Key: MODCLUSTER-141 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-141 Project: mod_cluster Issue Type: Task Affects Versions: 1.1.0.CR1 Reporter: Paul Ferraro Assignee: Jean-Frederic Clere Priority: Minor Trying to maintain one copy of the documentation for multiple versions simultaneously is proving to be a pain in the @ss... Magnolia is very cumbersome as a documentation tool because of its treatment of "paragraphs", especially with respect to code fragments (of which our docs have many). I recommend we keep all of the documentation in subversion (using doxia, docbook or similar) so that it is versioned along with the source code. The download page would contain links to the docs along side binary and source distributions. This seems to be how most jboss.org projects are setup. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (MODCLUSTER-139) Allow override of default clean shutdown behavior

by Paul Ferraro (JIRA)

Allow override of default clean shutdown behavior ------------------------------------------------- Key: MODCLUSTER-139 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-139 Project: mod_cluster Issue Type: Feature Request Affects Versions: 1.1.0.CR1 Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Minor Fix For: 1.1.0.CR2 By default, if a web-app is declared <distributable/>, we will only wait until there are no pending requests and all sessions are safely replicated. Only if a web-app is not <distributable/>, do we wait until there are no more active sessions, since there is no session replication. We need the ability to allow the user to override this default behavior, and use session draining even for <distributable/> apps, to avoid overloading remaining servers with failover requests. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (MODCLUSTER-145) mod_proxy timeout setting is not set correctly from nodeTimeout (JBoss) or ProxyTimeout (httpd) configuration in mod_cluster

by Brett Cave (JIRA)

mod_proxy timeout setting is not set correctly from nodeTimeout (JBoss) or ProxyTimeout (httpd) configuration in mod_cluster ---------------------------------------------------------------------------------------------------------------------------- Key: MODCLUSTER-145 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-145 Project: mod_cluster Issue Type: Bug Affects Versions: 1.1.0.CR1 Environment: CentOS5.4 Xen host JBossAS 5.1.0.GA running on jdk6 backend, on 2 hosts. mod_cluster configured in clustered mode. httpd-2.2.3-31.el5.centos.4 with manual mod_cluster configuration on frontend server host multicast disabled at a network layer jgroups configured with TCP transport and PING/gossip discovery Reporter: Brett Cave Assignee: Jean-Frederic Clere If 1 backend AS process is killed, the frontend proxy still connects clients to the dead node. The node is removed from mod_proxy after 5 minutes. All requests are directed to the dead node. mod-cluster manager status shows the node as status=NOTOK. client connections to this node result in 503 errors. After backend is removed from configuration after 5 minutes, requests to httpd still result in 503 errors as request is routed to the unavailable node. Even new sessions from different hosts try to get routed to the dead node, resulting in 503 errors. The note on www.jboss.org/mod_cluster/java/properties.html: When nodeTimeout is not defined, the ProxyTimeout directive Proxy is used. If ProxyTimeout is not defined the server timeout (Timeout) is used (default 300 seconds). nodeTimeout, ProxyTimeout or Timeout is set at the socket level. As per the configuration below, nodeTimeout is set in the Listener configuration. In addition to that, ProxyTimeout has been enabled and disabled on the httpd server. Timeout is configured with default of 120. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (MODCLUSTER-146) Quotes in jsessionId causing sticky sessions to fail

by Wim Vandenhaute (JIRA)

Quotes in jsessionId causing sticky sessions to fail ---------------------------------------------------- Key: MODCLUSTER-146 URL: https://jira.jboss.org/jira/browse/MODCLUSTER-146 Project: mod_cluster Issue Type: Bug Environment: JBoss 6 M2, mod_cluster's httpd Reporter: Wim Vandenhaute Assignee: Jean-Frederic Clere I am having an issue trying to setup sticky sessions for following configuration: 1 httpd front end 2 backend jboss instances What I am noticing is when running in a cluster, the JSESSIONID contains quotes like: Set-Cookie: JSESSIONID="DE0F7EEA2A5E90497D729DB27DDB4B25.192.168.7.11:8009:jboss.web"; Version=1; Path=/f00 Whilst not in a cluster: Set-Cookie: JSESSIONID=355F9E370912DC10187A15E8B02260CD; Path=/foo Now when I am looking in the httpd logging I see: mod_proxy_cluster.c(1681): cluster: Found value "54F0CFC4961C9ED14A64335B40645392.192.168.7.11:8009:jboss.web" for stickysession JSESSIONID In my opinion the quotes around the jsessionid is causing mod_proxy_cluster to fail in finding the jboss node to which to "stick" to. I recompiled mod_proxy_cluster with "HAVE_CLUSTER_EX_DEBUG" set for more debugging info and this confirmed my suspicion: mod_proxy_cluster.c(1739): find_nodedomain: finding node for 192.168.7.11:8009:jboss.web": mycluster mod_proxy_cluster.c(1752): find_nodedomain: finding domain for 192.168.7.11:8009:jboss.web": mycluster Looking in the code this shows that it was unable to find the node, due to the ending quote in the route. As for my JBoss Setup: * Uncommented ModClusterListener in jbossweb.sar/META-INF/jboss-beans.xml * mod_cluster.sar/META-INF/mod_cluster-jboss-beans.xml - changed ModClusterService to HAModClusterService - changed ${jboss.mod_cluster.advertise.enabled:false} to true As for my httpd setup: LoadModule proxy_module /opt/jboss/httpd/lib/httpd/modules/mod_proxy.so LoadModule proxy_ajp_module /opt/jboss/httpd/lib/httpd/modules/mod_proxy_ajp.so LoadModule slotmem_module /opt/jboss/httpd/lib/httpd/modules/mod_slotmem.so LoadModule manager_module /opt/jboss/httpd/lib/httpd/modules/mod_manager.so LoadModule proxy_cluster_module /opt/jboss/httpd/lib/httpd/modules/mod_proxy_cluster.so LoadModule advertise_module /opt/jboss/httpd/lib/httpd/modules/mod_advertise.so LogLevel debug CreateBalancers 0 <VirtualHost *:80> <Location /mod_cluster-manager> SetHandler mod_cluster-manager Order deny,allow Deny from all Allow from all # Allow from 192.168.7. </Location> <Directory /> Order deny,allow Deny from all Allow from all </Directory> ProxyPass /foo balancer://mycluster/foo stickysession=JSESSIONID scolonpathdelim=On nofailover=On KeepAliveTimeout 60 MaxKeepAliveRequests 0 ManagerBalancerName mycluster AdvertiseFrequency 5 </VirtualHost> Listen sebeco-dev-11:443 <VirtualHost *:443> ServerName sebeco-dev-11:443 SSLEngine on SSLProxyEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile "/opt/jboss/httpd/httpd/server.crt" SSLCertificateKeyFile "/opt/jboss/httpd/httpd/server.key" SSLCertificateChainFile "/opt/jboss/httpd/httpd/server-ca.crt" <FilesMatch "\.(cgi|shtml|phtml|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Location /> Order allow,deny Allow from all </Location> ProxyPass /foo balancer://mycluster/foo stickysession=JSESSIONID scolonpathdelim=On nofailover=On </VirtualHost> As my setup is not really complex at this point my gut says I am doing something wrong in the setup, but digging in the code shows the opposite.
