Detailed Description

TAO_Fault_Tolerant_Service.

A collection of ORB & ORB_Core related stuff that is needed at the ORB level. The ORB Core would carry an instance of this class and invoke methods on this. Note: This collection would be really useful when we have logging in place. The contents of this class can be logged at regular check point intervals.
