One Minute Evaluations for 25-27 March

CS 537 - Client-Server Interfaces

• Topic: RPC and RPC managers.

  Didn't get: Found it difficult to understand the RPC managers..

  One minute response: You and everybody else; how to best manage RPC systems is still an open question.

• Topic: CORBA, Jini; more [?] [?]; Understood the [?] and concepts of RPC..

• Topic: I got good idea about RPC system..

  Didn't get: Can you be bit detail how mapping between client and server calls is done. How client maps server functions..

  One minute response: At heart, it's just another name-address mapping; how much more complicated you want to get depends on the RPC system.

• Topic: RPC implementation description.

• Topic: RPC implementation.

  Didn't get: Generation of stubs of client and server; getting them. Hope project will help me out to get them..

  One minute response: That's why I assign them.

• Topic: We talked about ORB in CORBA and how to build RPC.

  Didn't get: Still not clear about the implementation.

  One minute response: The thing to do is implement two or three simple RPC systems completely by hand; after the third or fourth such system you should have a good idea of what is boilerplate and can be cranked out automatically by programs..

• Topic: RPC implementation, RPC examples.

  Didn't get: RPC service availability.

  One minute response: Determining if an RPC service is offered is difficult; it's one of the reasons CORBA's so complicated. Sun RPC, written mostly for LANs, fudges the issue by relying on the portmapper and well-known ports..

• Topic: RPC implementation and management.

• Topic: We talked about RPC-gen, RPC implementation, management, service description methods, CORBA.

  Didn't get: CORBA concepts are somewhat confusing (CORBA objects).

  One minute response: CORBA concepts are complicated, partially because they completely embrace the object-oriented paradigm.

• Topic: What is RPC?.

  Didn't get: CORBA.

  One minute response: It is not too far off the mark to think of CORBA as an operating system that works between a set hosts (or in the network) rather than on a single host.

• Topic: This week we talked about RPC routine, registration functions, implementation and the management issues of RPC.

  Didn't get: The difference between Sun RPC and CORBA is complicated..

  One minute response: In detal, but in concept the difference is simple: CORBA is like Sun RPC with a whole bunch of stuff heaped on top. The difference between the RPC part of CORBA and Sun RPC is also complicated, but CORBA works hard to keep the RPC mechanism hidden.
