Kaoru Matsumura commented on GERONIMO-2577:
-------------------------------------------
Hello Jeff and Shiva, I'm sorry to be late for reply.
I tried your new-config.xml and geronimo-web-hostlevel.xml(Host level
Clustering)on my RHEL environment.
Good! The clustering works perfectly. The same as your case , session gets
preserved successfully even onto the 3rd remaining node.
Would you please tell me why clustering doesn't work successfully (Context
level Clustering + DeltaManager) ?
Thanks

> URL: https://issues.apache.org/jira/browse/GERONIMO-2577
> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Clustering, Tomcat
> Affects Versions: 1.1, 1.1.1
> Environment: JDK - Sun java version "1_5_0_09"(32bit)
> OS- Red Hat Enterprise Linux ES4 update4(32bit)
> Http Server - Apache 2.0.59 +mod_jk 1.2.19
> Reporter: Kaoru Matsumura
> Attachments: config.xml, context.xml, geronimo-new.log,

> We run Geronimo cluster with three nodes.
> In our environment, with DeltaManager set for replication module, we found
> that the last node cound not continue the processes when the other nodes is
> intentionally halted in order.
> We recognize Tomcat 5.5.15 is OK with the same configuration and operations.
> Test Application
> ================
> The Web application program, which was used for the test, simply reads the
> number of access count, and then write the count to HttpSession object.
> Configuration?Files
> ==================
> We refer http://cwiki.apache.org/GMOxDOC11/clustering-sample-application.html
> * config.xml
> We add the following parameters to the standard configuration.
> <gbean name="TomcatEngine">
> <attribute name="initParams">name=Geronimo
> jvmRoute=nodeA</attribute>
> </gbean>
> Operations
> ===============
> 1 Have browser access to Test Application , and reload several times.(*1)
> HttpSession object is created on the nodeA.
> 2 And then, We kill the process of geronimo on the nodeA with $kill -9
> <Process ID>.(*2)
> 3 Reload the browser at one time. The node changes to nodeB.(*3)
> 4 Reload the browser several times.(*4)
> 5 And then, We kill the process of geronimo on the nodeB with $kill -9
> <Process ID>.(*5)
> 6 Reload the browser at one time.(And then, We expect that the process
> continues at the nodeC.)
> But the HttpSessionID of the HttpSession object is changed to another ID
> and the counter value is back to 1.(*6)
> As a result, the geronimo cluster cannot continue the process.
> For avoidance
> ===============
> When replication module is SimpleTcpReplicationManager, the geronimo cluster
> can continue the process.
