Servlet failover within iAS 6.0 SP3 cluster.
Hi June,
First of all sorry for delay in reply, I was very busy with my work.
I hope you have deployed the application on both of the iAS servers
and have already made all the required changes for these session
specific registry keys.
If cluster-servlet is wroking fine that means your cluster is okey,
however there are few more things that you
can try -
Few more things to check -
- when you do changes in the cluster settings in registry manually,
for a particular application, you need to restart the web server.
During web server start, the plugin creates a table for these
properties (for registered servers and session related information for
each comonent), which need to be updated when you change registry
manually. Please try restarting both of the webservers.
- open Admin tool, go to Application tab, click on the module node in
which you have put your servlet (it will show you properties of all
components in that module) just check that your servlet is Enabled
(check the radio button) and un-check the StickyLB radio button if
checked.
- click on your servlet (the Servlet Component properties... will
become alive) and click on the Servlet Component properties... Tab,
(it will show you all the Registered servers with this particular
servlet), if your servers are not listed there, than add them here.
Note: If you deploy your application on all the servers in the cluster
at a time from deploy tool, than it will register all the servers with
this application, provided the LDAP server you are using for these iAS
servers is same and the GUID is same (if you are not creating war/ear
modules from raw class files during deployment on each iAS servers,
and deploying same module created once) as it stores this information
with a particular GUID in LDAP server for a application/component.
Try these things, if it still gives you problem, please mail me your
application (war/ear) with all the xml files/descriptors.
Feel free to mail me any time if you have any query/question.
