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 ;)

Need Example on calling a unix shell script from oracle stored procedure

Hi
Can anybody give example on how to call unix shell script from an Oracle stored procedure. Please give a small example on how to do this .I need this urgently please.

If you are on 10g you can also use DBMS_SCHEDULER. See Re: Excute Unix command Using PL SQL

Calling linux / unix shell scripts from APEX

Hi -- I'm doing some prototyping, and would like to try calling a unix shell script on the server from within APEX.
Is this possible? Maybe thru Javascript? Other ways? Not sure if it's possible thru pl/sql.
FYI, I'm attempting to check username/password specified at login to see if it's a valid login
to another database (also specified at login). If there's an easier way to do this, I'd love to hear it!
We're highly motivated to have a single apex app work on multiple databases -- largely because of a lack of
administration resources on the other databases. All databases are accessible via database links from
the apex server (the links are necessary to implement other business rules), and I know I can get
the DML working. Powers that be prefer that Database Account authentication (or a facsimile thereof)
be used. I suspect I'm opening myself up to lots of criticism by disclosing this ... :)
Thanks for any ideas,
Carol

R -- If I understand you correctly, a pl/sql process in APEX could invoke a java program on the server. Is that correct?
If so, is there any reason it couldn't just call a unix shell script? Seems they're both just executables recognized by the OS....
I know I called unix scripts from embedded sql a billion years ago, but don't recall the method for doing that. What is
the syntax I'd use in apex / pl/sql?
thanks,
Carol

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

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

paragIf you are in 10g, you can simple call shell script from DBMS_SCHEDULER:
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'TEST_SCRIPT',
job_type => 'EXECUTABLE',
job_action => 'PATH_OF_YOUR_SCRIPT',
start_date => SYSDATE,
repeat_interval => 'FREQ=MINUTELY; INTERVAL=1',
enabled => TRUE,
comments => 'Shell script from Oracle'
END;

I have a ftp_ss.sh script which which ftps a file from remote server to local server, archives the last file and renames new file to the standard (ie file data store)name.
I want to run the above script and interfaces from a package.
Any help is greately appreciated.
Thanks,

In the package window, put "OS Command" from the toolbox.
Provide the command parameters to this tool in form of "/path/to/script/ftp_ss.sh"

Can i call unix shell script from B2B callout.

Hi,
We had a requirement to invoke a unix shell script from B2B callout implemented class. Here is the code in implementation class:
public void execute(CalloutContext context,List input,List output)
throws CalloutDomainException, CalloutSystemException {
try {
CalloutMessage cmIn = (CalloutMessage)input.get(0);
FileOutputStream fos = null;
String inputFile = "/home/orasoad/digitalsign/input/test.txt";
String outputFile = "/home/orasoad/digitalsign/output/test.txt.gpg";
File outFile = new File(inputFile);
String str =cmIn.getBodyAsString();
fos = new FileOutputStream(outFile);
Writer out = new OutputStreamWriter(fos);
out.write(str);
out.close();
String shellFile = "/home/orasoad/digitalsign/dg.sh";
String cmd[] = new String[] { shellFile, inputFile, outputFile };
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(cmd);
int i = pr.waitFor();
BufferedReader br = new BufferedReader(new InputStreamReader(pr.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
sb.append(line);
CalloutMessage cmOut = new CalloutMessage(sb.toString());
output.add(cmOut);
} catch (Exception e) {
throw new CalloutDomainException(e);
We were able to execute the unix shell script from standalone java class with same code. But some how it is not working as expected while invoking the B2B java callout.
Is it possible to invoke unix shell script from B2B callout?
Please give inputs.
Regards,

Though it's not a good idea to invoke shell scripts from java callout but technically it will work.
But some how it is not working as expected while invoking the B2B java callout.What is not working as expected? Any error in the log (server-diagnostic.log or server.out)?

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>

Run Unix command / Run Unix shell script from Forms9i

Hi,
I have a requirement to run Unix command and Unix shell scripts from Forms9i.
I know HOST command cannot be used directly. I also know we can create some JAVA stored procedure to perform the task, but I don't want to create any JAVA stored procedure as there are some security concerns.
Please point me towards any other way to achieve the same.
I would really appreciate your help.
Thanks,
Kumar

There is no reason why HOST can't be used. This is what it is for. As for using Java, it is not a stored procedure that you would be using, it would be imported Java (imported into the form).
The best way to use the HOST command is to call a script (.sh) rather than calling a Unix command directly. This is because HOST will not pick up environment variables set at the system level. So the script would first need to set the necessary environment variables then call the desired commands.

Execute a unix shell script from forms9i

Hi ,
I would like to execute a unix shell script form a form when they pressed a button. The forms server is on Linux machine. I tried but when I pressed the button nothings happen. Could some one please help me how I could get working.
Is there is a way I could execute the unix shell script from PL/SQL proceudre or package.
Please some one help me.
Bain

You would not expect to see anything happening because the
script cannot directly send output to the web form. However, you can get it to write output to a file and use web.show_document in the form after the host command to display the file and see the output.

BO v5.1 - creating a report from an oracle stored procedure

Post Author: newrochelle
CA Forum: Publishing
hi to all,
im using BO 5.1 and i need to create a document from an oracle stored procedure that have only one IN parameter and ten OUT parameters.
Creating the new report I selected the database connection then I choose the stored procedure name from the list, I inserted the value for the IN parameter and finally I click on Run button.
I got the following error message:
ORA-06550: line 1, column 38: :PLS-00103: Encountered the symbol
"," when expecting one of the following: : : ( - + case mod
new not null others <an identifier> : <a double-quoted
delimited-identifier> <a bind variable> avg : count current
exists max min prior sql stddev sum variance : execute forall
merge time timestamp interval date : <a string literal with
character set specification> : <a number> <a single-quoted SQL
string> pipe : <an alternatively-quoted string literal with
character set specification> : <an alternatively-q :-6550
it seems to be caused by the OUT parameters!
i leaved them without any value.
it's the first time that I used a stored procedure to create a BO report, but I think the OUT parameters are needed to do that, otherwise what data will be presented in the report???
can you help me?
please answear me ASAP.
Thank's in advance

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