Calling Operating system command from Database

I want to read a file list in a directory from a database procedure. I
m using Oracle 9i Release 2. How to do??? I don't want to user
external procedures. I know it can be done through java stored
procedure. Any other solution like a single command......Ja va code is
still ok...

There isn't a prebuilt "single command" solution. You have to write a
java stored procedure and a PLSQL wrapper procedure.

Read java docs and Look at list() or listFiles() functions in
"File" interface in "java.io" API. Goto http://tahiti.oracle.com
for Oracle docs.

Hint:
import java.io.*;
public class foo {
public static String getFileList (String dirname) {
....
File dir = new File(dirname);
String[] entries = dir.list();
...
}
}

Hello all, I have a C++ program, it does some calculations on things and then prints out a file in the format in which GNUPLOT can use. So my question is how would i call GNUPLOT from my C++ program. I know in some operating systems you can do system("gnuplot"); But not with red hat 7.3. So could some kind soul help me out? After it starts up GNUPLOT my program will terminate. Thanks

Hi all, I'm trying to call a C# dll from c++. I followed an example from the MSDN site, and I am able to get their example working, however, I believe their example is a console application, as it takes in command args. I'd like to be able to do the same thing, but from a c++ dll. However, when I port the same code over, it says it cannot create the instance (from the CoCreateInstance).

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
