Executing Unix scripts from a stored procedure

From the sql*plus windows, I am able to execute the host command and '!sh' commands; but I need to ececute Unix scripts from a stored procedure. Hoe can I do this? Where can I get good documentation on this? Any help would be greatly appreciated!
Thanks..

Hi,
U can use external procedure ( newly added feature in 8.0.3 onwards) and call any shared library. From shared library u can execute it.
One sql command is there HOST(' '). U can run a OS command. But u can not use it in PL/SQL.
U can call pls sql from shell !!!!!..
Thanks...

Trigger Unix Program from a stored procedure

Is it possible to start a Unix program as a background OS process from a stored procedure?
In fact I want to call a stored procedure which starts a Unix process. After the termination of this process get the results of the programm (a text file) using UTL_FILE package from the stored procedure and produce an HTML document based on the output of the started process using the htp package.
Thanks, JV

Whats the best way to start a host (Unix) program from a stored procedure or trigger without having to wait for a response from the program (i.e start it and forget it )The BEST way depends on your operating system and version of the Oracle database. If you are at Oracle 10g or higher, I would certainly suggest using dbms_scheduler. In 10gR2 you can set a program to execute on receipt of an event, and the trigger or stored procedure can be the cause of the event.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Last thing... note that opens a potential giant size security hole into the Oracle Server Platform. So implement it properly using a proper Oracle security model.

How execute Unix script from java?

Can I execute Unix script from java?

Yes. Using ProcessBuilder. And read [When Runtime.exec() wont|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]. It's old, but pretty much all of it is still true.

Hi,
Register your Shell Script as a concurrent program, Executable execution method "Host", then use fnd_request.submit_request to submit the program.

Problem executing Unix script from Java...

Hi there, I'm having trouble executing a unix script from a java program. The script receives multiple parameters and it seems that one of them ( or more ) is not well interpreted. When I run the script directly from a shell, the script executes without any errors. But, when I run the exact same script with the exact same parameters, it does not work.
Here is the command to execute the script with all the parameters that is executed from the shell ( with success ) and also from the java program ( with errors ):
/z/opus/dcap/intfu001.csh 'NODEBUG^NOTKPROF^NOSTACK' opus dcap JACQUES JACQUES '2625781' 'ORA$PIPE$001D00D70001' JOB^DEBUG^SINISIMU^STATPROD^DECTIDANC^81^503^4080^86^87^151^97^98^99 BUT^N^N^SPRI^0^13^24^3^J^05^N^19^19^19 >> /tmp/switcher8.999.null.pgm.test
And here is my portion of code that executes the script:
Runtime wShell = Runtime.getRuntime();
Process wProc = wShell.exec(cmd_unix_final);
wProc.waitFor();
return wProc.exitValue();
Please give me your thoughts on this!
Thanks in advance!

Ok.
Let's proceed surgically, else we'll never solve or overcome anything.
In the last your reply you wrote:
the normal output is what I get when the script runs successfully, the script first prints a few things
and then does stuff that takes at least 2 or 3 secondsWhat do you mean?
-Finally have you got your script correctly executed?
The stuffs you spoke of are really performed?
If this is the case I can't see the prob.
Is your concern only about exitValue() for it doesn't let you distinguish programmatically
the success or failure of the script execution?
Of course you surely already have a routine in your java code to handle
exceptional situations of errors from the script.
And the "normal output" is just what you must parse to detect those errors.
Then who cares about exitValue() in this case?
Don't invoke it, relay on the stdout and stderr of the script.
-Or you get only a deceiving standard output
that let you think the script execution went alright, while instead it didn't.
In this case we have to investigate some other thing.
I can't still exclude that the problem isn't related with the buffer size of the stdout
allocated by the environment to the subprocess. You spoke of few things printed out.
Be explicit. What's the size of the output you get?
And is the "normal output" complete till the very last char
or is it truncated from somewhere on?
Also it's important that you hit a ps command after the java main process terminates
(or simply when waitFor() returns) and see if the script subprocess hung up.
As an alternative approach directly call your pro*C code from Java through JNI, instead of translating it.
1. Exec.java
public class Exec{
     static{
          System.loadLibrary("Exec");
     public static native void proCFunct();
     public static void main( String[] args){
          proCFunct();
}2. javac Exec.java
3. javah Exec
4.Exec.c
#include "Exec.h"
JNIEXPORT void JNICALL Java_Exec_proCFunct(JNIEnv * a, jclass b){
     //here call the function that executes the script
5. cc -G -I$JAVA_HOME/include -I$JAVA_HOME/include/solaris -I$YOUR_INCLUDES Exec.c -o libExec.so

I am trying to execute a unix script by calling it in BODS job. It is giving an error saying Program terminated with exit code 127. The same script when i am executing in UNIX it is working fine. I am unable to trace the issue.

Hi Sabre,
As per the guidelines provided by the article, i had done below changes..
InputStream is = null;
InputStreamReader iStreamReader = null;
BufferedReader bReader = null;
String line = null;
try{
String fileName ="test.ksh";
String argValue ="satish"; // value passed to the script
String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
Process proc = Runtime.getRuntime().exec(exeParam);
is = proc.getErrorStream();
iStreamReader = new InputStreamReader(is);
bReader = new BufferedReader(iStreamReader);
System.out.println("<ERROR>");
while((line = bReader.readLine()) != null)
System.out.println("Error is : "+line);
System.out.println("</ERROR>");
int exitValue = proc.waitFor();
sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
Now , it's showing something like..

Executing unix scripts from java...

Hi guys,
I'm pretty new at this java stuff, but can someone tell me if it's possible to have a java object that connects to a specific unix box through a given IP and Port and execute a Unix shell command? The shell script creates a file that will be later ftp'ed from the UX box back to the PC I ran the java program from. Any ideas?
Thanks in advance.

Yes I thank it can be done. I have not done it but you prob can do it through tcp/ip useing ServerSocket and socket class.Make a server with the ServerSocket class on the linux box that is listening to the port and when it gets the right signal from your client on your pc/win the server will activate the sell script with the Runtime.getRuntime().exec(shellscript);
Well just a thought GOOD LUCK

Starting Unix Script from pl/sql procedure

I would like to start any unix shell script out of oracle.
I don't want use DBMS_PIPES, because then I always need a unix daemon.
Is there a package wich allows to a call similar to
"os_result := dbms_systemcalls.call_unix_system
('/usr/bin/ls -la');
null

What version of Oracle are we talking about here? If it's v8 then I think what you're after is a pl/sql external procedure which I can tell you how to set up.
