With Cobol-RPC
you can deploy your aplication across LAN's,
WAN's, even the Internet, using Windows or UNIX
servers. What's more, you can even have non-Cobol
programs on the client, such as Visual Basic
programs, call legacy Cobol programs on the
server, without recoding the server programs!
Just think, now
you can add a graphical user interface to your
Unix application! You can relieve network
bottlenecks by relocating data intensive programs
to the server. You can even run your application
across the Internet.
Cobol-RPC
is your ticket to client/server. Combining
simplicity and rapid redeployment with the
ability to design applications geared for the
architecture of the next century, you have to try
Cobol-RPC today!
What Cobol-RPC
Will Do For You...
- Let you
deploy your existing Cobol application in
a client/server architecture without
recoding
- Let you
use Cobol on the client and the server
- Let you
create non-Cobol programs for the client
that call Cobol programs on the server
- Prevent
you from rewriting your server programs
- Relieve
network bottlenecks by relocating data
intensive programs to the server
- Add a
Windows graphical user interface to
legacy applications running on UNIX
servers
How Cobol-RPC
Works...
The functional
unit of COBOL applications is the program. Cobol
applications are built by Cobol programs calling
other programs. What Cobol-RPC does
is allow this call mechanism to function across
any network with TCP/IP protocol support. We call
it a remote program call. It is the foundation of
client/server programming.
Cobol-RPC
client programs can be written in Cobol or
non-Cobol languages like Visual Basic. They can
call Cobol programs located on the server as
easily as if they were locally available. Client
programs require little or no special coding,
depending on the COBOL being used. With some
implementations remote program calls are made
with the standard CALL statement, just as if they
were local. Other implementations use a special Cobol-RPC
function for remote program calls. This special
function is analogous to the Cobol CALL
statement.
Cobol-RPC
server programs require absolutely no special
coding. They receive and return parameters in the
Linkage Section, just as if they were called
locally. Since server programs execute on the
server, they can access server data directly
without transferring data over the network. Only
the parameters passed in a remote program call
are transferred across the network. This allows Cobol-RPC
to dramatically reduce network traffic and
improve performance. Multiple levels of remote
program calls are also supported. This means a
server program executing on a departmental server
can call a server program located on a central
server, while executing a remote program call
from a client.
