Naming service and security service

WebSphere V5 does not use a database to store its name bindings. If a database is used for the security repository, users cannot log in during a failover, but will succeed after a failover.

In order to minimize lookup failures, you can code your applications as follows:

if (obj==null)

	ctx.lookup(obj);

Since the system has run for a while before a failure, the object you are looking up may already exist, so you do not need to look it up.
