How to retrieve information on UNIX Host from oracle Forms

Question

Hi,
Has anybody tried to retrieve manipulated information
on the Unix Server From the oracle forms running on a client ?.
If it is to be done by user exit and calling the pro*c code
then where should the pro*c code exist ?. on server or on client.
1. If on server then can that code return the value to form ?.
2. If on client then can that code access the unix server and
return the value ?..
OR
any other method or tool to do the above.
Thnaks and regards

Answer 1

I can only tell you what we've done for our system. We have
client applications which need to send/recv information from the
UNIX server (report submission, etc.)
We have a deamon (written in PRO*C) which runs on the UNIX
server. This deamon constantly monitors a pipe (using the
DBMS_PIPE package available with ORACLE 7.1). The client apps.
send requests through this pipe and wait for the server deamon to
process the request and send responses down a "return pipe".
This approach has served us well.
With ORACLE 8, you can (according to what I've read) link
external object modules (similar to ORA_FFI on the client), which
would make these OS specific functions available to the database
developer via PL/SQL but we're just now looking at ORACLE 8 so I
have no first hand experience with this.
