Executing a shell script from pl/sql stored procedure

Hi,
I have Oracle 8i on HP-UX.
I am passing a shell script name as a parameter to a user defined function from a pl/sql stored procedure. This user defined function has insterface to a user defined Java class file in Aurora java virtual machine which is written using runtime class which can execute any OS command or any shell script. I am getting any OS command run successfully, but could not run my own shell script. It's is not getting environment variables of my own, so not getting executed. So please suggest how can get these env variables in my shell script and also suggest other sucurity concerns to be taken into consideration.
If you have any questions please let me know.
This is really a very urgent issue.....
Please help me.
Thanks
Srinivasa Rao Kolla

Your best bet is to use the dbms_pipe builtin package to send the command to the host

Call a UNIX shell script from an oracle stored procedure

We need to call a UNIX shell script from an oracle stored procedure
i.e. the control should come back to the procedure once the script completes. Can any body help to achieve this ?

There are various ways in achieving this.
For Example, you can call a PRO*C-Library residing on the database server.
This requires a PL/SQL library to be generated and some changes to the Listener configuration.
It is also possible to implement a java procedure on the database being invoked by a PL/SQL wrapper class.
In this way (and if used right) there is also granularity regarding the filestructure permissions given and it may be called during a Forms or other PL/SQL session.
The article below explains a more generic approach how to invoke shell commands from within an Oracle Instance.
Be careful with this, because it really works ;)

How to pass arguments to a Unix shell script from PL/SQL?

We want to run a Linux shell script from PL/SQL (10g). This is our code to run the script only and it works fine.
dbms_scheduler.create_job
          job_name=>'RUN_LINUX_SCRIPT_' || v_job_name,
          job_type=>'EXECUTABLE',
          job_action=>'/vol0/FileLoadDir/Bank/DATA_FILES/spell_check.sh',
          enabled=>TRUE,
          auto_drop=>FALSE
        );Now we have a requirement to pass 2 arguments to the .sh file. In the .sh file the 2 arguments are defined as $1 and $2.
I used this method.
dbms_scheduler.create_job
          job_name=>'RUN_LINUX_SCRIPT_' || v_job_name,
          job_type=>'EXECUTABLE',
          job_action=>'/vol0/FileLoadDir/Bank/DATA_FILES/spell_check2.sh',

          number_of_arguments => 2,
          enabled=>FALSE,
          auto_drop=>FALSE,
          comments => 'Testing by Channa'

Call Shell Script from PL-SQL

Hello All,
I have been using some well known Java Class and Procedures to execute shell scripts from PL-SQL.
The different environments I was using before were
1)
Operating System (Server) AIX version 5
Oerating System(Client) Microsoft Windows XP Service Pack 2
Oracle Database Version Oracle Database 10g Enterprise Edition Release
10.2.0.1.0
2)
Operating System (Server) Red Hat Linux 3.4.5-2
Oerating System(Client) Microsoft Windows XP Service Pack 2
Oracle Database Version Oracle Database 10g Enterprise Edition Release
10.2.0.1.0
But suddenly I had to drop and recreate the Databases on 1st (AIX) environment
and
reinstall the Operating System (Server) Red Hat 3.4.5-2 on IInd environment stated above (which obviously means the reinstallation of Oracle Database there!)
Now the shell script(through PL-SQL)is executing smoothly for the IInd (Linux) environment[b] but not executing for the Ist (AIX) environment
and I am not getting how to solve the problem.
I have given all the permissions to users, shell scripts and all as they were before.
Can you please help?

Executing a shell script from a Trigger

All,
I have to write a script to do the following requirement.
There is a file called BUSINESS_DATE.TXT.
This file get updated once the oracle partition created. In Oracle, Partition will be created every day. There is a seperate script scheduled to take care ORACLE partition creation.
The above file will have only one row. i.e
03092012
If Oracle partition creation job failed, the above file won't be updated.
My requirement is,
I have to check whether the BUSINESS_DATE file is updated today or not. If yes, I will have to move the files from common area to input file directory to process those files.
All file name will amend with current date.
i.e
LIDDIFD03092012.TXT
The key part is to check the BUSINESS_DATE.TXT file is updated properly or not.
We don't know what time the file will get updated. So we are planning to schedule the new script to run for every 15 mins to check whether the file is updated or not
But...I just thougt instead of writing a shell script to do the above one, Why shouldn't I capture the date in a table (New table needs to be created) and use ORACLE TRIGGER to run the shell script to move the files from common area to input file directory to process those files?
My Proposal in ORACLE :
Create table business_date
rep_date varchar(15),
curr_timestamp timestamp
Once the oracle partition created , one row will be inserted into the above table. This adjustment needs to be implemented partition script.
Once this table get record, TRIGGER should call SHELL SCRIPT to move the files from common area to input area.
If I implement ORACLE TRIGGER, The script which will check whether the file got updated or not for 15 mins is not required. Right? Inputs from experts are welcome!

Triggers should not be used to do transactional work. There is no COMMIT in a trigger. What happens if the trigger runs the shell script and then a ROLLBACK occurs? You will have run the shell script when it shouldn't run.
Create a stored procedure to run the shell script. Call the stored procedure when the partition is created.
If you were using 11g and interval paritioning you wouldn't need to create the partitions manually. Oracle could create the partitions automatically.

Executing a shell script from a java program

Hi,
I'm facing a problem while executing a shell script from a jsp page.
I'm using exec() function.
It's working fine for single statement scripts.But if the script consists of any database processing and some other processing statements,it's not returning the correct exit status of the process.
Will u please help me in this.
If there is any other ways to execute a shell script from a jsp page other than Runtime.exec().If so let me know.
Thanks in advance.

I think this shud workMaybe - but it is wrong! Why do you create aReader
and then read bytes which are turned into a String
without worrying about whether or not the bytes area
String and without worrying about the character
encoding if the bytes do represent characters and
without worrying about how many bytes wereactually
read.
Also, both you and the OP should read, digest and
follow the advice given in
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-
traps.htmlI dont care if it is wrong. This code works for me.
We are here to solve problems not to find which post
is wrong.It is wrong! You are posting bad advice that is very wrong! It may work for you but it is wrong in general! WRONG WRONG WRONG.
If you have a solution then post it I did post a solution! The reference I gave will explain to you and the OP exactly how it should be done.
rather then
posting rude comments.I was not rude! I was explaining just some of what was wrong!

Hello,
It's hard to help you but what you can do is listening to the outputs of your script, you should read the output stream and error stream and send them to the default console.

Error while executing unix shell script from java program

Hi All,
I am trying to execute unix shell script from a java program using Runtime.execute() method by passing script name and additional arguments.
Code snippet :
Java Class :
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);
     int exitValue = proc.waitFor();
     sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
}Test.ksh
export -- application realated paths..
nohup abc.exe 1> test.log 2>&1;
$1
exit.By running the above java class , i am getting exit Value: 139 and log file test.log of 0 bytes.
when i am running the same command (/usr/bin/ksh test.ksh satish) manually, it's calling abc.exe file successfully
and able generate the logs properly.
Pls let us know where exactly i am stuck..
Thanks in advance,
Regards,
Satish

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..
<ERROR>
</ERROR>

Execute a shell script from inside PL procedure

Oracle 9205 on Red Hat Enterprise Linux 3.
Is there any way to execute an O.S. shell script from inside a PL/SQL procedure?
This is, that PL_SQL procedure evaluate a situation and if the condition is true, it calls and execute an O.S. shell script.

PL/SQL procedures do not support any native calls to the OS; however, you can code calls to external procedures or JAVA procedures to perform tasks on the OS.
Prior to these two methods any of the following packages dbms_alert, dbms_pipe, or utl_file could be combined with a daemon type program to issue OS commands, run shell scripts, etc....
There is a writeup on metalink with examples.

Example: Executing a shell script from java

Hi. There are many other posts in the forums related to executing a unix script from java, but I wanted to post another example that I thought might be helpful...
The key thing to executing the script is to include the -c switch for the sh command. This tells the sh command that you are passing a string to be interpreted as input. Without this switch, the script does not execute as you'd expect it to. Also, use a string array to pass each part of the sh command.
Here is a working sample class, along with a test script to execute it:
public class TestShellScript {
public static void main(String[] args)
String[] chmod = {"chmod","777","testscript1"};
String[] runscript = {"sh","-c","./testscript1 > jdata.out"};
Runtime rtime = Runtime.getRuntime();
try
rtime.exec(chmod); // Set the authorities for testing
rtime.exec(runscript); // Run the script with redirection
catch (IOException e)
e.printStackTrace();
rtime = null;
Here is a test script to wrap the java call:
#!/bin/sh
cd /<your script dir>
export -s CLASSPATH=/<your jar dir>/TestShellScript.jar
export -s PATH=/<your script dir>:/usr/bin
java TestShellScript
- Hope this helps.

I don't know exactly but the code written below is working fine try the same with your code .Even with your code instead running the code with
" ./<filename> ",if you execute it with "sh <filename>" command without changing the mode of the file it is executing properly.
import java.io.*;
import java.util.*;
public class ScriptBuilder
public ScriptBuilder()
public void writeScript() throws java.io.IOException
FileWriter writer = new FileWriter(new File("test_script"));
writer.write("#! /bin/sh\n");
writer.write("ll>/home/faiyaz/javaprac/checkll");
writer.flush();
writer.close();
Runtime rt= Runtime.getRuntime();
rt.exec("chmod 777 test_script");
rt.exec("./test_script");
} public static void main (String[] args)throws java.io.IOException
ScriptBuilder sb = new ScriptBuilder();
sb.writeScript();
}

APEX - accepting OUT variable values from PL/SQL Stored Procedure

I have created a page (Form) which is accepting values text fields.
In the Page Processing section under Processing, I am passing the values to a PL/SQL Stored Procedure, which acts like an API. The procedure contains code to validate the entered data and finally insert the data into the base tables. The procedure also contains OUT variables in the parameter that would return status of processing and any error messages.
Now, my question is, how can I make the page accept these OUT variables from the procedure. What I wish to do is, to capture these messages/processing status from the procedure in the page. For example, if there is a error in the data and the procedure is sending this message in the OUT variable, I need this to be displayed on the page as an error message.
Is this possible in APEX?
Regards,
Santhosh Jose

Hi VC,
I just tried putting the string directly instead of the variable. Its still not giving me the expected results.
HOWEVER, I think the reason was because of the EXCEPTION block in my code. I have an EXCEPTION block to handle exceptions. I commented the WHEN OTHERS section and now the error message is coming on the page.
So what I have done now is as follows: At the point at which the error is expected, I am raising a handled exception. And within the exception handling, I am giving RAISE_APPLICATION_ERROR.
WHEN ex_main_error*
THEN*
p_status := 2;*
p_msg := 'ERROR Stage: '||lc_err_stage||' ERROR Message: '||lc_err_msg;*
RAISE_APPLICATION_ERROR (-20001, p_msg);*
This is working now! Which is very good news. Thanks once again for your help!
Regards,
Santhosh Jose
