Bad console export, worse documentation for session replication setup

Question

Hi,
I'm having problem configuring config.xml/weblogic.xml to get in-memory session rep going for WL 6.0
sp1.
I already have everything up and running in 5.1 sp8; so I figure I can just export my
weblogic.properties settings to 6.0's config.xml via the console, right? Well, here's my original
properties:
weblogic.httpd.session.enable=true
weblogic.httpd.session.cookies.enable=true
weblogic.httpd.session.timeoutSecs=10000
weblogic.httpd.session.cookie.comment="Kiko session tracking cookie"
weblogic.httpd.session.cookie.domain=.kikotest.com
weblogic.httpd.session.cookie.maxAgeSecs=-1
weblogic.httpd.session.persistence=true
weblogic.httpd.session.cacheEntries=1024
weblogic.httpd.session.persistentStoreType=replicated
When I use the console export tool, I find NONE of these settings in config.xml!!! So I look
through the docs to see if I can do this manually, and the documents are just as confusing! This
mapping table:
http://e-docs.bea.com/wls/docs60///////config_xml/properties.html#1152226
seem to suggest that each session flag from weblogic.properties is mapped to two corresponding flags
in config.xml and weblogic.xml (e.g. persistentStoreType -> (config.xml) SessionPersistentStoreType
& (weblogic.xml) PersistentStoreType). Does this mean I have to set the flags for BOTH files? Or
just one? Which one???
As for config.xml flags which have "N/A" in the "Console Label" column, does this mean I just add
this flag as a top-most label, like:
<SessionPersistentStoreType>replicated</SessionPersistentStoreType>
And to further add to the confusion, when I look at the document for "Configuring In-Memory HTTP
Replication in a Cluster" http://e-docs.bea.com/wls/docs60/cluster/servlet.html#1009453, it tells me
to "set the property PersistentStoreType to replicated in the Web Application deployment descriptor,
web.xml."? I thought it was weblogic.xml???
I think all of these confusions can easily be alleviated by fixing any one of the following, if not
all three:
1) /console export of weblogic.properties to config.xml needs to translate these session flags
2) /console needs to have access to these session flags so we don't have to poke around config.xml!
3) Documents need to be less ambiguous about how to set these flags

Hi Gene,
I believe the documentation is incorrect - sessionPersistentStoreTyped doesn't need to be set in the
config.xml file (I don't believe this tag still exists). The file name should be weblogic.xml and has
the following general form:
<!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 6.0//EN"
"http://www.bea.com/servers/wls600/dtd/weblogic-web-jar.dtd">
<weblogic-web-app>
... other stuff from the dtd if you like
<session-descriptor>
<session-param>
<param-name>PersistentStoreType</param-name>
<param-value>replicated</param-value>
</session-param>
</session-descriptor>
</weblogic-web-app>
weblogic.xml goes in the WEB-INF directory in your war file.
Hope this helps,
Glen
