Calling Operating System Commands from PL/SQL using java

Calling OS Commands from Plsql
but i had user privilege problem
Declare
x Varchar2(2000);
Begin
x := OSCommand_Run('/tmp/sri/GROUP_ho.sh');
DBMS_OUTPUT.Put_Line(x);
End;
o/p;
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
i done the grant privillage also
part
dbms_java.grant_permission('abcd', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
dbms_java.grant_permission('abcd', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
dbms_java.grant_permission('
abcd', 'SYS:java.io.FilePermission','<<ALL FILES>>', 'execute');
again
get
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
same error;

Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back.

Calling Operating system command from PL/SQL programs

Hi
Is there any way we call the unix shell script from PL/SQL procedure/functions

In 10g, it is possible.
BEGIN
dbms_scheduler.create_job(job_name => 'myjob',
job_type => 'executable',
job_action => '/app/oracle/x.sh',
enabled => TRUE,
auto_drop => TRUE);
END;

How to: execute operating system commands from PL/SQL

System: IBM pSeries AIX

Is there a quick way to execute operating system commands from PL/SQL?
Without creating a JAVA class....
I need to execute a Loader script.
I want to do this from within PL/SQL.
I need to to do 4 things.
Three require SQL scripts.
The fourth is SQL*Loader.
The usual way is with a UNIX script calling 3 SQL scripts and one Loader control file.
Is there way to do all this from within ONE PL/SQL SCRIPT ??
Just let me know.

How to call Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

Are you using a webserver? If so, you could make your operating system script into a CGI program, then execute it from pl/sql using utl_http.request.

Is it possible to call operating system command after file receive?

Hi expert,
I'm trying to call operating system command after file receive comm.channel receive a txt file.
operating system command uses txt file name as parameter.
Is it possible? How?
Thanks.

Hi,
It should be possible, actually we have two options that are
1.RUN OS command before message processing
2.RUN OS command after message processing.
So you can give the commands in the RUN OS command after message processing.

We do not use JDeveloper but use external procedures/routines called from the database. Then you can call a database procedure to an operating system task.

Error while calling .svc web service from pl/sql using utl_dbws

Hello Folks,
I am calling a .svc web service from pl/sql using utl_dbws and encountering the following error
javax.xml.rpc.soap.SOAPFaultException: The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher.

Calling a WCF service from pl sql using a scheduler.

Hi
I am completely new to everything pl sql related. Right now, I need to call a WCF service method that returns a dataset. Then i need to take that dataset and insert the data into a table in the database. I want to do this by having a scheduler be called once a day.
Does anyone have any code, examples etc?
thanks

And WCF stands for what? In what version of the product?
First rule for someone new ... don't make the assumption that we can look over your shoulder or read your mind.
What you seem to want is the built-in scheduler. The docs are at http://tahiti.oracle.com.

OS command from PL/SQL code

Is there any way of running on OS (Operating System) command from SQL or PL/SQL. i.e. calling an executable from a trigger.

Is there any way of running on OS (Operating System) command from >SQL or PL/SQL. i.e. calling an executable from a trigger. Ashis,
Here's an example of a simple piece of Java you can create using SQL*Plus:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "RuntimeExample" AS public class RuntimeExample {
public static String runNotepad() {
String returnValue = null;
Runtime r = Runtime.getRuntime();
try {
     Process p = r.exec("notepad.exe");
     returnValue = p.toString();
     } catch (Exception e) {
          System.out.println("Exception calling Runtime.exec()->" + e);
     /* You can get creative here and
     1) Use p.waitFor() to block while the process is running,
     2) Send the command to be executed as a parameter to the method, etc. */
     return returnValue;
CREATE OR REPLACE FUNCTION runNotepad RETURN VARCHAR2 IS
LANGUAGE JAVA NAME 'RuntimeExample.runNotepad() return java.lang.String';
DECLARE
my_varchar2 VARCHAR2(64);
BEGIN
my_varchar2 := runnotepad;
DBMS_OUTPUT.PUT_LINE(my_varchar2);
END;

Execute external operating system command

Hi Friends,
I have a requirement to run a script file with extention '.PL' on the application server using ABAP.
i have sample how to run it in XI.
XI3.0 provides a very simple way of handling this using the "Operating System Command" in the File Adapter.
I post my output file in the following folder,
/usr/sap/sapout/test/
The shell script is available in the following path,
/usr/sap/bin/convert.pl
The figure below explains as to how we call the shell script using "Operating System Command".
File Acess parameters
      Target Directory      = /usr/sap/sapout/test/
      File Name Scheme = TestOutput.txt
Processing Parameters
     File Construction Mode          = Add Time Stamp
     File Type                              = Binary
     Operating System Command = /usr/sap/bin/convert.pl %F
I have to do the same thing in ABAP as it has been done for XI as mentioned in the above example.
My operating system is UNIX.
If any one can give me a sample it would be really helpful to me.
Thanks in advance,
Arundhathi.

Hi Arundhati,
You can run operating system commands from ABAP.
e.g. If you want to change UNIX right for any file, you can use following code.
lv_ucomm = 'chmod a+rwx 123.txt'.
CALL 'SYSTEM' ID 'COMMAND' FIELD lv_ucomm.
whatever command you provide in Field parameter ( lv_ucomm in the above case ), ABAP run that command at operating system level.
In your case, you can provide command in lv_ucomm to run script at operating system level.
Hope it will help you.
Regards,
Naren
