Jeff,
Upgraded tomcat, tomcat_ajp and jasper to 5.5.15 and ran the clustering
tests.
The *good* news...
Load balancing, sticky session, session replication and session
failover seem to work using the same deployment plan that was created
for G1.1 w/ TC 5.5.9..
The *bad* news...
*Problem1*
When testing Sticky session, my browser locks unto a particular cluster
member (e.g. node1) due to the nodeid in the cookie. If I kill node1,
the session fails over into node2 and all my session data is still
present. This is good.
The nodeid in the cookie continues to say node1 (this is also true w/ TC
5.5.9 w/ and mod-jk)..
Now, if I restart node1 and wait a minute or so and then hit my browser,
I am directed to node1 and all my session data is gone. :(
BTW, an earlier run using TC 5.5.9 also resulted in being directed back
to node1 though the httpsession is retained. I think this may be
related to problems replicating data whenever nodes are added.. Which
leads me to ...
*Problem2*
Whenever a cluster member is added to the cluster, the other nodes
receive the following exception. This occurs both during the initial
addition of a node and after a stopped node is restarted...
(Though later when I access an httpsession (via a servlet request)it
does result in session replication between members.)

Getting a bunch of exceptions relating to session invalidation

This one may not be new..

Dave,
Thanks for doing this.

I've validated that the Geronimo clustering example
(http://opensource.atlassian.com/confluence/oss/display/GERONIMO/Geronimo+Clustering+Example)
still works for Geronimo 1.1 (with Tomcat 5.5.9). The application
deployment plan (attached to email) required some changes.
I'm now rebuilding G1.1 with Tomcat 5.5.15 to determine if the
clustering Gbeans and plans still work..

Perhaps Filip can fill us in on this.
If I remember right, the 5.5.9 clustering GBeans will work on forward
versions. So I don't think there is a problem there. HEAD has been set
to 5.5.15 for quite some time.
Nevertheless, it doesn't hurt to try em out ;-)

Jeff (et al.),
Will G1.1 definitely be upgraded to Tomcat 5.5.15?
IIRC, the clustering deployment plans were quite different for 5.5.9
-vs- 5.5.12. If we upgrade to 5.5.15, we will likely need a new plan
that accounts for both the webcontainer upgrade as well as the new G1.1
plan format..
Thanks

Jeff Genender wrote:
Thanks Rainer. But I think 5.5.15 will be the one for 1.1. But
possibly 5.5.17 for 1.2 ;-)

Just for your information: 5.5.16 was released a couple of weeks ago,
but has some problems with de delivered packaginf of examples app
under
windows.
5.5.17 is expected to be cut on friday and voted stable eventually 1-2
weeks later.

Yep...need to update the plan. Its updated in trunk.

It appears that G1.1 is still using Tomcat 5.5.9
http://svn.apache.org/repos/asf/geronimo/branches/1.1/etc/project.properties
Wasn't a tomcat upgrade to 5.5.15 in plan for G1.1?? Perhaps I am
confused with the plans for trunk.. ??
Thanks
