Hi All:

I am using windows 2000 server with Eclipse.
In the dost prompt, I ran the file run_sqlldrTest2.cmd and it loaded record into the Oracle database.
I tried to do the same thing in java calling the run_sqlldrTest2.cmd. In java it states the "The command line job - -executed successfully."
However, I donot see the record being loaded into the database.
What am I doing wrong?

If I comment out the "cmd[2]=set PATH=C:\\OraHome_1\\bin;" line and ran RunCmd.java, on the line for P.waitFor() it would freeze there forever:

Any help for suggestions would be greatly appreciated!!




import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RunCmd
public static void main(String[] args)
Process P;
Runtime r;

r = Runtime.getRuntime();

try {
String[] cmd = new String[4];
cmd[0] = "cmd.exe";
cmd[1] = "/C";

cmd[2]="set PATH=C:\\OraHome_1\\bin;";

try {
P = r.exec(cmd);
int Exitcode = P.waitFor();
if (Exitcode != 0)
System.out.println("The command line job did not execute successfully");
System.out.println("The command line job - " +
" - executed successfully."); //break

catch (Exception e)

System.out.println(" 1 e.getMessage():"+e.getMessage());

} catch (Exception e)
System.out.println("2 e.getMessage():"+e.getMessage());

set PATH=C:\\OraHome_1\\bin;
C:\test2009\scripts\run_sqlldr.cmd test2009/test2009@orcl control=C:\test\scripts\ctl\amcare.ctl log=C:\test\scripts\log\NAC20090150005112.txt.log data=C:\test\scripts\data\NAC20090150005112.txt bad=C:\test\scripts\bad_files\NAC20090150005112.txt.bad discard=C:\test\scripts\dis_files\NAC20090150005112.txt.dis;

echo %* > C:\test2009\scripts\log\sqlldr.log
sqlldr %* >> C:\test2009\scripts\log\sqlldr.log

Its windows code.
There is no way I can test it.
You do simple debug.
Instead of calling the sqlldr, just try to display to screen (system.out.println).
Post how the java runtime is calling sqlldr and its parameters.
Anything useful in sqlldr logfiles?
