Call unix script within plsql block

Hi all,
can i call a unix script within a plsql block for example
my unix script name is - Diff_dataload_process.sh
declare
begin
select * from ......;
Diff_dataload_process.sh
exception
end;
please help me.
Thanks,
Krupa

Hi, I think you need something like this:
DBMS_SCHEDULER.create_program
(program_name => 'sch_program',
program_type => 'EXECUTABLE',
program_action => '/home/nobody/input/test_job.sh',
number_of_arguments => 0,
enabled => TRUE,
comments => 'Test Program'
end;
and there's another ways to do it:

Call unix script within Servlet - need to wait for completetion

Hi,
I have a servlet which grabs some information from my web form and then calls a unix script.
This already works fine and does what i need it to do. I now need to add some functionality where i can get the servlet to wait for the unix script to complete before carrying on and then redirecting back to the user.
the code i have for the current servlet is:
         * EXECUTE THE UNIX COMMAND.
        Runtime   oRuntime =     Runtime.getRuntime();
        Process   oProcess   =     null;
        String[]      cmd          =     {"/bin/sh", "-c", sPath}; // UNIX
         * ERROR CODES 3 = File not found
        try
          oProcess = oRuntime.exec(cmd);
        catch(Throwable t)
          t.printStackTrace();
        }I am assuming i need some sort of wait method to handle this. Any help would be greatly appreciated.
Thanks
Graham

ok.. you code is fine.. you can run any shell script or program using the exec() method. if you need to wait till the process finishes then you need to call the method waitFor() in class Process.. the method blocks the parent thread (servlet) till the sub process (your exec'd script or program) terminates.
hope that solves your problem.. :-)
Pls tell me one more thing.. are you using netBeans or Eclipse for executing the programs or you use standalone tomcat to deploy the application. I have problem in execing programs when i deploy in tomcat 5.5 and the same application works fine in netBeans 5.0. if you know pls help me too..
Thanks,

How to call unix script/command in ODI

Hello Gurus,
Please let me know how to call unix script/command in ODI?
Thanks
Shridhar

you can call shell script using the OS command found in Package.
Step 1. Drag the OS Command in the Packgae
Step 2. In the Text mentiond call the script say for ex sh /opt/path/script.sh
Step 3. Execute.
Note : Make sure the User through which ODI is triggering does have the required permission to execute shellscript , also always provide the full path , since scripts are execute from the oracldi/bin folder so its necessary to provide the complete path of the script location.
Hope this helps.

Unix command from Plsql block

Can any one tell me what i doing wrong in this code.
I m working on Oracle 11g and AIX unix server.

Calling unix script using oracle forms

we have to call unix script using oracle forms , a trigger in form calls stored procedure on database
that stored procedure on database calls a oracle shared library
but since the only listener account for oracle on our unix server is oralist , whenever a call is made to the unix script from the oracle form , the unix script is executed by oralist user
but issue that we are having now is since oralist is specific for listening connections from orale we dont want to use this user to establish SFTP on it to avoid any issues with oralist
we want the sftp to be established on soem other useraccount , so is it possible to do something so that the script is executed by an account other that oralist.

I'm not a Linux/Unix specialist, but I think this may work: let your database call a shell script that does a su command before running the actual script:
su - other_account
your_script.sh

Calling Unix-Script from within Oracle and store stdout/stderr in table

Hi,
What I want to do is:
1. Calling a UNIX script (e.g. hello.sh) (from inside the Database)
hello.sh
echo Hello World!
2. and get the stdout/stderr output back in my Database in a table (e.g. temp_back)
table temp_back
ID stdout stderr
1 Hello World!
I think Number 1 isnt a big problem, but how to get stdout back in DB?
Any solution?
I searched a bit in this Forum and found this Post.
re:Calling Host Command Through Database Procedures or Triggers
This may be what I am searching for, but cant access the Link
Since I am not really fit with UNIX and packages/procedures in Oracle it would be nice if you could post a very detailed answer.
(Please no java)
-What packages do I need? (heard DBMS_OUTPUT would be useful)
-example PL/SQL script
Thanks a lot!
Marcus
Environment:
Oracle 9.2.0 DB

Marcus, if you opened the Java sandbox to access any o/s file, you can call any Unix command, shell script, or program, that the Oracle o/s user has exec privs on.
Just remember that there's a very basic Unix environment when you make the call - the settings in the .profile does not apply. Thus PATH for example is not set. When making the call make sure that the complete path is given. As for the environment, that is a problem as you cannot set that and make the call at the same time.
In that case it is much simpler to rather write a Unix shell script that does all for you. Set the environment. Run the command(s). Format output. Etc.
Then you call that Unix script, via Java, from SQL or PL/SQL. Treat the Unix scripts like the Unix-version of stored procedures for your Oracle application.
Some technical details. When you connect to Oracle, a Unix process services you. This can be either a dedicated server process (servicing only your Oracle session) or a shared server process (from the shared service pool of processes).
In either case, it is a Unix process running as a background process (thus detached from any tty device). PL/SQL and SQL are executed by this process. The Oracle JVM created by your session also lives in this process. When you therefore make o/s calls, these calls are made by this process.
Therefore you are limited to what this process can and can't do. E.g. it runs as the oracle o/s user and will fail on accessing paths and commands does the oracle user does not have privs on. Etc.

Calling UNix Script from portal Form

Has anyone conquered this issue through jav or plsql. I need to call a unix script from the portal form when I select the insert button.

I have several very convoluted ways which all work, but I have always thought there should be more straightfwd ways. Fundamentally the easiest way to call something from the Insert button is to add some PL/SQL code before (or after) the "doInsert();" call in the Insert Button event handler.
What seems to be lacking is the ability to get from pl/sql to the o/s. So until we know how to do that you have to call a method in Java to execute o/s commands - specifically you can use Runtime.getRuntime().exec(cmd); where Runtime is a class in java.lang, and cmd is the actual o/s command (script or whatever).
How to call this Java is then where you have several options:
1. Compile this piece of Java into the Oracle DB as a SP.
2. Deploy this piece of Java within a Java servlet on a 9iAS instance. Then have another SP call this servlet using the utl_http package (begin_request and other sp's within package).
Which options would depend on several factors including your preference but most importantly whether you have a DB or a 9iAS instance on the machine where you want to execute the script. If you have neither you have a problem. In such cases I have used a standalone OC4J container which has a very small footprint.
As I said these methods are all quite convoluted and if anyone else has anything better I would like to know (but they work quite reliably).
Cheers.
Anton.

Calling perl script from PLSQL

Hi All,
I have created Java stored procedure and oracle function to execute the os commnad, this works fine for calling batch scripts but when i used same function to call perl script,
like how we call in batch script
perl <script name> the sql gets hanged.
Is it possible to call perl like this?
or is their any other way to call from plsql
Thanks Chandra

Are you able to run that perl script at DOS command line?
Did you call the perl script directly from the java proc or you put the perl command line in a DOS .BAT scirpt and called that from the java proc?

Calling Unix scripts in ODI

Hi all,
I'm having unix scripts for file validation.How and where to call this Unix scripts in ODI?Please be in steps.
Advance thanks
Suresh

Hi Suresh,
Its very straight forward in ODI.
For your package, click Tools, under Utilities you will find, OSCommand, type the exact path of your script file and make sure your agent should have all access rights to invoke the script.

Calling sql script in plsql procedure

Hello,
I have a sql script named mytest.sql and i want to execute this from a stored procedure.

Actually i want my sql script to run daily to export some tables data.
I can execute this script from a sql prompt but i want to run it from enterprise manager.
I am using oracle 10gR2 on windows2000 system.
Any idea about scheduling the sql script to run automatically??
How to execute this sql script from a plsql procedure??
Thanks

Hi all,
Thanks for all the replies. I have found the solution with external procedures.
Following is the complete step by step guide.
1. Create the OSCommand Java Class using the following statement:
connect as any user:
create or replace and compile java source named oscommand as
import java.io.*;
public class OSCommand{
public static String Run(String Command){
try{
Runtime.getRuntime().exec(Command);
return("0");
catch (Exception e){
System.out.println("Error running command: " + Command +
"\n" + e.getMessage());
return(e.getMessage());
2. Create the following Wrapper Function using the following statement:
CREATE or REPLACE FUNCTION OSCommand_Run(Command IN STRING)
RETURN VARCHAR2 IS
LANGUAGE JAVA
NAME 'OSCommand.Run(java.lang.String) return int';
3. connect as sys
Execute dbms_java.grant_permission( 'FKHALID','SYS:java.io.FilePermission', '<<ALL FILES>>','execute');
execute dbms_java.grant_permission( 'FKHALID','SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '*' );
execute dbms_java.grant_permission( 'FKHALID','SYS:java.lang.RuntimePermission', 'readFileDescriptor', '*' );
commit;
note: here fkhalid is the oracle user.
connect as fkhalid user:
Declare
expdp_cmd Varchar2(2000);
Begin
expdp_cmd := OSCommand_Run('cmd /c sqlplus fkhalid@mtcedwt/pwd @d:\ORA_DUMPS\mydbexp.sql');
DBMS_OUTPUT.Put_Line(expdp_cmd);
End;
In Unix
Set Serverout On
Declare
x Varchar2(2000);
Begin
x := OSCommand_Run('/home/test/myoscommand.sh')
DBMS_OUTPUT.Put_Line(x);
End;
I will check the dbms_scheduler also and will let you know the results.
Thanks

ugh, what an ugly "design". I can see your life will be full of performance issues, strange 'bugs', and other unpleasant side effects. I mean, it all looks "so cool", but it'll be a nightmare to maintain and enhance.
but then you have the issue of binds, which will be intractable. You'd have to know the binds at compile time, but you have hidden all of your sql in a magic generic table - so you cannot possibly know your binds at compile time.
I would suggest you discard all of this code (I am DEAD SERIOUS) and start over. This is a bad idea from the get go. Or at least do me a favor and do not use plsql (you make it look like a good database implementation, but it isn't)
The objective here is to store SQL Statements in a Table(a sql repository) and just call the required SQL from the application using the sqlid using the sql_execute procedure. ...
CHANGE YOUR OBJECTIVE.
How about this for a good objective:
the objective here is to store sql statement in a plsql routine (a sql repository, you call a procedure and we run sql) and just call the required sql form the applicatoin using the STORED PROCEDURE
sorry, can I think of hacks to get you going? yes, application contexts come to mind - a fixed number of binds comes to mind. Am I going to work them out? No - it is the wrong way to approach a database application.
