Invoking Shell Script from JAVA Stored procedure

I am trying to invoke shell script using Java Stored procedure.
When I run my java class outside of oracle using oracle user
account it works but as soon as i load it into database and try
to inovoke that class using PL/SQL wrapper it runs java class
but is not able to invoke the shell script. Any ideas would be
greatly appreciated.

Pleass search the forums for "runtime" as there are many threads and examples already posted.

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

Invoking a UNIX shell command from Java stored procedure

The program below is suppose do send an email using UNIX mailx program. It works correctly when I compile it in UNIX and invoke it from the command line by sending an email to the given address.
I need this program to run as a stored procedure, however. I deploy it as such and try to invoke it. It prints the results correctly to the standard output. It does not send any emails, however. One other difference in execution is that when invoked from the command line, the program takes about a minute to return. When invoked as a stored procedure in PL/SQL program or SQL*Plus anonymous block, it returns immediately.
Why would mailx invocation not work from a stored procedure? Are there other ways to invoke mailx from PL/SQL?
Thank you.
Michael
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
public class MailUtility
public static void main(String[] args)
System.out.println(mailx("Hey, there", "Hello", "oracle@solaris10ora", 1));
* Sends a message using UNIX mailx command.
* @param message message contents
* @param subject message subject
* @param addressee message addressee
* @param display if greater than 0, display the command
* @return OS process return code
public static int mailx(String message, String subject,
String addressee, int display)
System.out.println("In mailx()");
try
String command =
"echo \"" + message + "\" | mailx -r [email protected]" + " -s \"" + subject + "\" " + addressee;
if (display > 0)
System.out.println(command);
try
Process process = Runtime.getRuntime().exec("/bin/bash");
BufferedWriter outCommand =
new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
outCommand.write(command, 0, command.length());
outCommand.newLine();
outCommand.write("exit", 0, 4);
outCommand.newLine();
outCommand.flush();
process.waitFor();
outCommand.close();
return process.exitValue();
catch (IOException e)
e.printStackTrace();
return -1;
catch (Exception e)
e.printStackTrace();
return -1;

try adding the full explicit path to "mailx" in the command string that gets sent to Runtime. i would guess that the shell that gets spawned might not have a proper environment and thus mailx might not be found.

Invoking a bash shell script from Java code

Hi All
I am trying to invoke a Bash shell script using java code. The arguments required are "source wmGenPatch <source dir> <destination dir> no_reverse.
in the code I have specified the arguments considering the cannonical paths of the files as the code may run on Unix or windows platform.
I am getting a error while invoking Runtime.getRuntime().exec(args). The error is as follows :
"The Error Occurred is: CreateProcess: source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=2"
It seems that error=2 indicates that the 'file not found' exception. But i can see the directories referred to in the error at place in the workspace.
Kindly advice.
Thanks in advance.

Hi All
I am pretty new to invoking bash shell scripts from java and not sure if i am progressing in right direction.
The piece of code tried by me is as follows
try {
               currentDir = f.getCanonicalPath();
          } catch (IOException e) {
          if (currentDir.contains("/")) {
               separator = "/";
          } else {
               separator = "\\";
          String args[] = new String[7];
          args[0] = "/bin/sh";
          args[1] = "-c";
          args[2] = "source";
          args[3] = currentDir + separator + "DiffEngineScripts" + separator
                    + "v4a02" + separator + "wmGenPatch";
          args[4] = sourceFileAdd;
          args[5] = destFileAdd;
          if (isReverseDeltaRequired) {
               args[6] = "reverse";
          } else {
               args[6] = "no_reverse";
          try {
               Process xyz = Runtime.getRuntime().exec(args);
               InputStream result = xyz.getInputStream();
               InputStreamReader isr = new InputStreamReader(result);
               BufferedReader br = new BufferedReader(isr);
               String line = null;
               while ( (line = br.readLine()) != null)
                    System.out.println(line);
               int exitVal = xyz.waitFor();
               System.out.println("Leaving Testrun.java");
          } catch (Throwable t) {
               t.printStackTrace();
and on running the same i am getting Java.io.IOException with the stack trace
java.io.IOException: CreateProcess: \bin\sh -c source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=3
kindly advice

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 !!!!!..

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.

Return national language strings from java stored procedures

Hi, all.
How does i can return String which contains national characters from java stored procedure? I.e. convert UTF java string to national language of database. It's does not processing automatically (why?).
declaration of procedure:
CREATE OR REPLACE FUNCTION TestNLSString RETURN VARCHAR2
AS
LANGUAGE JAVA
NAME 'test.SomeClass.getNLSString() return java.lang.String';
SELECT TestNLSString AS X FROM DUAL;

OS: Windows 2000 Server
Oracle Server version: Oracle 8.1.7.1.4

Ok. I had a specific problem.
I want to use java stored procedure (function) to make a connection to remote db using supplied connection parameters make some quieries there end return results in a form of structured data - object.
I have defined an object type in a database where the function will reside. I granted execute privilege to public user on this type, made public synonyms to both, the object type and the function, so anybody connected to the same database would have an access to this functionality.
I supposed that if I supply connection parameters for some other user but the same database when running the function, everything should go smooth. Yeah.
My java code executed ok: it made a connection to the db with some x user, it resolved object type descriptor given (oracle.sql.StructDescriptor), but pl/sql wrapper function reported the error I've mentioned. If I executed the function giving it the connection parameters for same account as where object type was declared, everything went fine.
My final solution is:
Make TWO! connection in java code: 1st for ("jdbc:default:connection:"), 2nd for remote database account.
Use first connection to construct oracle.sql.StructDescriptor
Use second connection to retreive data from remote db

You can set environment variables as the second argument to Runtime.exec(). You can pass argument on the command line. So, what sort of argument do you want to pass?
