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.
