I have few basic doubt about clustering....
a) How can we maintain single instance model / no duplicate instance across JVM (without terracota server)
b) Do we need any programatic code required for single instance (like keep the db locked and do not allow second server to create instance?
c) If my load balancer (app server level& hardware level) is perfect, still do I need any program/ code to handle?
thanks in adv.

Do you mean a Singleton class? If yes you'll need to use SingletonServices from weblogic.
