The CMP documentation answers all of your questions.
Sorry that should have been clustering documentation (The CMP documentation is very good as well.)
thank you very much.
Yes I am cluster documentation.
We have JAAS login module custom implementation .
while testing failover , when one node goes down (shutdown) switch to other node seems to look for security contact switch and not finding (I am not sure).
The problem that I have may be related to how security contact switch happens in case failover. any input on JAAS and failover contact switch info might help in resolving this issue
