remote reference

A remote reference RREF(P) is a special global reference. The →smart pointer always

refers to a stub object. Given this, a method call using a remote reference is always

handled using a →remote call. Remote references occur on the client side in strict

client/server hierarchies.

request

Request is a synonym for call.

resource manager

Resource managers, which manage their resources locally using transaction

monitoring, are only used in relation to distributed transaction processing. The most

common example of a resource manager of this kind is a database.

restart point

An →end of transaction or a →data link point is a restart point under GINA. In the case

of a rollback, the operation is restarted at the restart point using the same request/call.

rollback

see →end of transaction

Run Time Type Information

RTTI allows you to specify the type of the object at runtime.

server

A server waits in a client/server system for a request/call from a →client. It provides

→services for the client. A server can make subrequests/subcalls to other servers and

can thus act as a client.

Servers are transaction-monitored under T-ORB. Non-transaction-monitored servers

can also be connected using T-ORB/Client.

server process

A server can consist of one or more operating system processes. A number of client

queries are generally processed by different server processes.

server stub

In DCE terminology, a server stub is the same as the →external interface under GINA.
