Call C++ programs from PL/SQL

Can someone give me an example of how to call C++ programs from PL/SQL ASAP please?
Thanks
Chitra

Hello,
You can use External Procedure facility of of PL/SQL (Assuming your DB is 8 or 8i)
Please refer the doc at http://oradoc.photo.net/ora8doc/DOC/server803/A54654_01/10_procs.htm

Calling Cobol program from PL/SQL

What is the caling convention for PL/SQL to call a Cobol program?

You cannot do it directly from PL/SQL. PL/SQL is.. well, kind of abstract ito the actual platform it runs on. PL/SQL cannot talk directly to operating system. It cannot (itself) do socket calls, file I/O calls, use the printer, etc.

All this has to be done using a lower level implementation library - like UTL_FILE for example that wraps internal C written modules that does file I/O. PL/SQL can call these to do I/O on its behalf. Ditto for wrappers like UTL_TCP and others.

There is no default wrapper for calling external processes from PL/SQL. It can however be done indirectly using the external procedure (EXTPROC) feature, or using Java to do it.

The latter is the easiest. You create a Java stored proc that can access the operating system and run external programs and commands. You punch a big hole in the Oracle Java security to allow this Java stored proc access to the operating system. Next you create a PL/SQL wrapper for this Java proc which then in turn can be called from PL/SQL.
Just remember that you MUST secure this hole you've punched into Oracle security. If any Oracle user can access this PL/SQL wrapper, they can hack, compromise, trash or simply destroy your entire Oracle account on that server.
Here is the basic code:
create or replace and compile Java Source named "OSCommand" as
-- java: OS COMMAND
-- descr: Executes an Operating System Command using the JAVA RTS
-- IN parameter: os command to execute (including fully qualified path names)
-- OUT parameter: returncode [\nstring]
-- where string a max of 32000 chars of the output of the command
-- (note that \n is used as separators in the string)
-- returncode=-1 Java RTS error occurred (e.g. command does not exist)
-- returncode=255 o/s command failed (e.g. invalid command params)
import java.io.*;
import java.lang.*;
public class OSCommand{
 public static String Run(String Command){
 Runtime rt = Runtime.getRuntime();
 int rc = -1;
 try{
 Process p = rt.exec( Command );
 int bufSize = 32000;
 int len = 0;
 byte buffer[] = new byte[bufSize];
 String s = null;
 BufferedInputStream bis = new BufferedInputStream( p.getInputStream(), bufSize );
 len = bis.read( buffer, 0, bufSize );
 rc = p.waitFor();
 if ( len != -1 ){
 s = new String( buffer, 0, len );
 return( s );
 return( rc+"" );
 catch (Exception e){
 e.printStackTrace();
 return( "-1\ncommand[" + Command + "]\n" + e.getMessage() );

Calling java program from PL/SQL code

Dear,
How to develop and call a java program from PL/SQL code?
What about if this program will call other java programs?

Perhaps the Java Developer's Guide would be a good place to start

Calling java program from PL/SQL

I already have a java program that encrypts/decrypts data.
How can I use or rather call this program in PL/SQL?

Calling external program from PL/SQL

Does anyone know whether it's possible to call an external program living outside of Oracle from PL/SQl eg. a from a stored procedure?
Specifically i want to call back into my java appserver (ejb server) when a trigger/stored proc. is executed.
The call does not have to be synchronous, some sort of queue will do - eg JMS??
Any help greatly appreciated.

Hi
Which version of oracle you are using.
If it 8i, you can use external procedures/libraries. REfer to ORacle PLSQL documentation.
If you are using Oracle 7+ you can use dbms pipes to post your command string and a cron job to read the pipe and execute the string.
An alternate ugly way is to write to a file and some process reading the file at a regular interval.

Scenario to call c programs from pl/sql

I know that c routines can be called from Oracle pl/sql. But, I would like to know that anybody has the realtime scenario where it is unavoidable.
Please let me know if anybody has any specific scenarios.
Thanks in advance
Sudhir

There are numerous scenarios - as Oracle is operating system agnostic (mostly) and do not provide numerous 3rd party interfaces.
For example, you want to use MAPI (Microsoft's Mail API). You can write a C dll that provides an easy and basic interface into MAPI - and then define this C dll as external procedure that enables you to perform PL/SQL calls to logon to a Microsoft Exchange Server, verify and get users, send mail, enumerate the contents of a mail box's folder, read a mail, and so on.
Or something more complex. Oracle is used by an application server that provides automated telephonic call centre support. You know - the automated system that answers your support call, asks numerous questions, gets input from you and attempts to troubleshoot your problem. Modern systems like these use speech recognition interfaces - where the caller can (using plain English) state the problem, instead of pushing tone buttons on the phone.
Such a system will need XML templates defining the speech recognition interface context - these templates with define the basic sentence structures the caller will use, words used, assign values to the words for processing and so on. These XML templates (together with the troubleshooting data and rules) can be stored in Oracle.
One function needed will be to verify the XML template with the speech recognition system used. Again, this can be done from PL/SQL. When a new template is entered into the database, PL/SQL can make an external proc call to a C dll that interfaces with SAPI v5 (Microsoft's Speech API) to compile the XML template and determine whether it is valid or not.
There are literally 1000's upon 1000's of such scenarios that requires one to call external services and interfaces from PL/SQL - and the external proc feature of Oracle is often the technical solution that can be used to address the requirement.

How to call VB program from PL/SQL ?

hi, i use oracle8i and i would like to call program VB from Stored procedur or PL/SQL program.
Is it possible and how?
thanks

If you are trying to invoke a WebService, it shouldn't matter what under what platform that WebService compiled or where it is executing, as long as it is on a shared network. That is the very "definition" of a WebService. You should be able to invoke the webservice via TCP sockets, streaming XML message content.
If your VB WebService isn't, in reality, a WebService and you need to invoke it as an ActiveX dll that is possible with Oracle COM Automation. The 8i/9i data server must be running on the win32 platform that has the ActiveX dll installed. I'm not sure if there is any DCOM possibilities (though I suspect not). In all circumstances, if you data server is running on a non-win32 platform, you are out of luck.
If you are trying to invoke an ActiveX application (not a dll) from the 8i/9i data server, you are pretty much out of luck, too.
Hope that helps,
Michael

Calling Java programs from Oracle Stored Procedure

Is it possible to call Java programs from Oracle stored procs? If possible Can this be used to exchange data from other applications? Is there a better method/feature in oracle for doing data exchange with other apps?

If what you mean by Oracle stored procedures is pl/sql then yes.
You can create a "wrapper" this way:
CREATE OR REPLACE FUNCTION xmlXform
in_mapUrl IN VARCHAR2,
in_inputUrl IN VARCHAR2
RETURN VARCHAR2
AS
LANGUAGE JAVA NAME
'com.yourcompany.xml2any.xform(java.lang.String,java.lang.String)
RETURN java.lang.String';
Then load the java as:
loadjava -user youruser/youruserpasswd -resolve -verbose lib/xmlparserv2.jar classes/com/yourcompany/xform.class classes/com/yourcompany/xml2any.class
The java, given the correct permissions, can do anything java can do including communicate with outside applications.
Is this the "best" way... depends on what you are trying to accomplish.

Call HOST cmd from PL/SQL Block

Hi ,
I'm trying to call the HOST command from stored procedure
declare
cmd varchar2(100):='c:\file.bat';
begin
execute immediate 'host('c:\file.bat')';
dbms_output.put_line('Executed');
end;
but,It gives an error msg on execute immediate stmt.
Plz resolve this problem.
Rgrds,
Anand

You are confusing SQL*Plus's command (a client) with that of PL/SQL.
Just as you cannot code C# commands, or Perl commands, or PHP commands in PL/SQL, you cannot code SQL*Plus commands in PL/SQL.
SQL*Plus runs on your client platform. It has a couple of commands.
PL/SQL is a server side programming language. This runs inside the Oracle server process servicing the client.
This server process does not know your client language commands. Nor can this server process hack across the network, break into your computer, and access your local file called c:\file.bat.
Yes, you can execute server o/s commands and execute server programs from PL/SQL via a Java stored procedure or via the EXTPROC interface. Refer to the sample code in [url http://forums.oracle.com/forums/thread.jspa?messageID=1439836#1439836]this thread on how to call server o/s commands and server programs.

Can you check from which schema you are executing FND_REQUEST? You can try as follows;
Connect to your required schema, create a synonym on apps.fnd_request, connect from apps and finally execute grant all on apps.fnd_request to all.
You can check for relevance from Doc ID: Note:147495.1
Please do keep in the mind the soultion above should be applied to a test/dev EBS instance first.
I hope this would be of help.

How to call a program from FM which acts as popup?

Hi,
I need to call a program from FM and once the program is called it needs to be opened as a popup. Maybe we need to assign size when we call from FM or do we need to give size in the program it self?
I know i can either use the Submit command or Call Transaction command. But that it self will open a full screen which i dont want. It needs to be of a smaller size.
Any help will be appreciated.
Thanks

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:
