Context : The requirement is measuring the performance of ORB layer in our appliaction.We are using openorb1.3.1 on client side and omniorb on server side. basically we need to find at a particular time how many request are waiting in queue at the ORB end. Bacause what we feel is that since our request are getting clogged in the queue if we can come up with some figures for finding queue size at run time than we might find a workaround for the same. Pointer for Interceprtors will also be of great help. Also if some body can get us the classes which are used for making request queues than it will be great. Thanks in advance.
