Use this task to override the default non-fair locking policy for all singleton session bean write locks within the server. This task is for WebSphere® Application Server users who do not want lock requests for their Singleton session bean method invocations to follow a non-fair policy.
When locks are constructed as non-fair, the order in which locks are obtained is not guaranteed. If readers are active and a writer enters the queue, subsequent readers might get granted the read lock before the writer is granted the lock.
