Incorporate shell commands from forms

How to incorporate unix shell commands(eg. ls, cp) from forms9i?
In Windows environment,it is possible by issuing
host command(eg. HOST('DIR >k.lis') -- it moves the list of files from Oracle9i/forms90 path to a file k.lis).
The same thing I have to do in a unix environment.

I think you have the wrong forum. This forum has to do
with the UIX technology inside of JDeveloper. Your
question seems to have to do with UNIX or forms. I can't
tell which.

Execute shell command from within pascal code

Hello there,
I am trying to execute a shell command from within my pascal code. I use XCode together with FreePascal. I have tried something like:
exec ('program', 'options');
adding the 'Dos' unit to the Uses clause of my program.
Thus, e.g.,
exec ('mkdir', '/A')
to create a directory with the name 'A'.
However, my attempts so far were unsuccessful. Can anyone help me on this, and perhaps provide a simple example of how to do it right?
Thank you in advance,
Shane

In the mean time, I found the problem myself. I am just posting the solution here for anyone that is interested. My original solution was correct, in that the 'Dos' Unit must be added, and that the right command is 'exec'. There was however a problem with the correct path to the program that I wanted to invoke. In the shell, this program was accessible from anywhere. However, in the 'exec' command, the full path to the program must be given. Since I am not a Unix expert, I don't know the reason for this.
So, in summary, the solution is:
Uses Dos;
begin
exec ('full path to program', 'program options');
e.g.: exec ('/bin/sh', '/run.sh') to process the commands in the file /run.sh
end
Hope this may be of help to anyone else.

Execute shell command from Java

Hi all,
I need some idea for executing shell script from Java programe.
For example i have start.sh script in /tmp/start.sh folder of unix server.
I want to execute shell script from local java code.
Any idea on this.

How to Execute Power Shell Command From Windows Application.

Hi All Experts,
I want to execute power shell commands from my windows application.
Is it possible ?
Please let me know your comments..
Thanks.

I have not tried this, but apprently it is easy as in the sample pasted below. please see this article for more details
http://geekswithblogs.net/Norgean/archive/2012/09/19/running-powershell-from-within-sharepoint.aspx.
Let me know how it goes...
public string RunPowershell(string powershellText, SPWeb web, string param1, string param2) {
// Powershell ~= RunspaceFactory - i.e. Create a powershell context
var runspace = RunspaceFactory.CreateRunspace();
var resultString = new StringBuilder();
try
// load the SharePoint snapin - Note: you cannot do this in the script itself (i.e. add-pssnapin etc does not work)
PSSnapInException snapInError;
runspace.RunspaceConfiguration.AddPSSnapIn("Microsoft.SharePoint.PowerShell", out snapInError);
runspace.Open();
// set a web variable.
runspace.SessionStateProxy.SetVariable("webContext", web);
// and some user defined parameters
runspace.SessionStateProxy.SetVariable("param1", param1);
runspace.SessionStateProxy.SetVariable("param2", param2);
var pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(powershellText);
// add a "return" variable
pipeline.Commands.Add("Out-String");
// execute!
var results = pipeline.Invoke();
// convert the script result into a single string
foreach (PSObject obj in results)
resultString.AppendLine(obj.ToString());
finally
// close the runspace
runspace.Close();
// consider logging the result. Or something.
return resultString.ToString();
Ok. We've written some code. Let us test it.
var runner = new PowershellRunner();
runner.RunPowershellScript(@"
$web = Get-SPWeb 'http://server/web' # or $webContext
$web.Title = $param1
$web.Update()
$web.Dispose()
", null, "New title", "not used");

Shell commands from JSP after Forms migration

During application migration from forms 9i to JSP & BC4J, I have to code the following Forms code into my JSP application.This is for a button pressed trigger.
DECLARE
RENAME_STRING VARCHAR2(120):= 'RENAME C:\BRC\PDATA' ||:DRAWING_ACCOUNTS.ACCOUNT_ID|| '.TXT P' || :DRAWING_ACCOUNTS.ACCOUNT_ID || TO_CHAR(SYSDATE,'DDMMYY')|| '.txt';
BEGIN
HOST( RENAME_STRING, no_screen );
web.show_document( 'http://hostname/selectfile.html', '_new');
     IF NOT Form_Success THEN
          Message('Error -- File not Renamed.');

Calling a shell command from LabVIEW

Platform:
Labview 8.6 on Fedora 10.
The VI is generating some data that I wish to convert to a form that a Windows user can work with (with CR/LF as the EOL). Is there a way to issue a shell command (specifically: $unix2dos <generated file name>) from within labview ?
Solved!
Go to Solution.

Hi,
have you tried the "System Exec" function? According to context help it should work on UNIX too...
Btw. you have asked a related question in an other thread. Wouldn't converting the string data in the VI itself work? Or making a special VI for that purpose and enable the conversion by a switch (like "Win compatible format?")?

Running Copy command from Forms 6i

HI!
I want to run Copy command through Forms 6i i.e copy from scott/tiger@orcl insert test@msora(ename) using select to_char(ename) ename from emp;
I can run DDL command through Forms_ddl functions in Forms 6i, But copy command is not working using Forms_ddl.
thanks in advance.
Edited by: Kami_Lily on Aug 2, 2009 10:04 PM

Dear Kami Lily,
Oracle Forms is able to execute SQL and PL/SQL command only. Additionally it supports Operating System command by HOST built-in.
Though COPY is a SQL*Plus command, it is not possible to execute this command by HOST built-in.
Instead, if you hardly want to execute COPY command oracle forms 6i, then you make a batch file in operating system and run that batch file from HOST built-in.
Thanks.

Executing shell commands from Java.

I want to execute shell commands in Java using the Runtime.exec( String ) method.
The method works fine under Linux OS, but under Windows '98 the method didn't work at all!
For example the following call: Runtime.exec( "dir" ) throws an exception showing that the command was not completed. If I replace dir with ls under Linux all is good. What is the problem with the Microsoft Windows '98 ? Is there any solution at my problem ?!
thx in advance!

hey JSarmis,
You can help me... "ls" doesn't work for me on linux.. using Runtime.exec, some commands work, others don't... you may hold the key to what i need? How did u get "ls" to work?

How to call a HP-UX command or shell script from Forms 4.5

Does anybody know how to call a unix command or shell script to get a files list of HP-UX server from Oracle Forms 4.5 on client side? I tried to use DBMS_PIPE package to get it done but I failed. Please let me have the solution if anybody knows how. Very urgent!

I tried the host command before and it just let me shell to the DOS environment but not HP-UX environment as Forms was running on Windows platform. So, I could not run a unix command or a shell script. Is DBMS_PIPE the only way to get it done?

Run a shell script from FORM

Hi,
Is there a way that we can run a shell script on UNIX box from ORACLE FORMS 4.5 running on client PC (OS=windows on client,

Thanks in advance for help

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Anton Weindl ([email protected]):
You can either use rsh or rexec (both available on windows). You will have to edit the .rhosts in the home directory of the unix user the script will be run under:
<Client-Hostname> <USER>
<USER> must match the Windows-User exactly.
You can then execute the Shell-Script with
host('rsh <HOST> -l <USER> sh <SCRIPT>',NO_SCREEN)
Hope that helps

Thank You Anton Weindl,
It seems like the thing I want to use instead of the dbms_pipe.
I tried to use rsh and gives me the following message
command: "rsh taurus -l nileshs test.sh"
where taurus is hostname and
guest is unix username
I am logged on windows 2000 with this name.
"taurus permission denied:"
"rsh can't establish connection"
Let me know if I am missing anything.

Execute OS command from form in 10g

Hi,
Is there a equivalent function/procedure in 10g forms for HOST command available in 6i?
Migrated a form from 6i to 10g that contains HOST procedure. Now this is no longer working in 10g forms.
Thanks

Hello,
I attached webutil.pll to the form and changed HOST to CLIENT_HOST.
This is the actual code
PROCEDURE CheckFTPDaemonStatus IS
    Str                VARCHAR2(100);
BEGIN
-- Check if FTP Daemon is up
Str := 'ps -efx | grep TPFTP.jar | grep -v grep';
Client_Host(Str);
IF (NOT FORM_SUCCESS)
THEN
        Message_Box(NULL,'FTP daemon is unavailable. Please start the FTP daemon.',0);
        EXIT_FORM(NO_COMMIT);
END IF;
END;This procedure is invoked when the form is being opened. Now the form itself is not coming up. Though ps -efx | grep TPFTP.jar | grep -v grep from UNIX command line shows this JAR is executing at OS level.
I am running the form on HP-UX
How do I check if CLIENT_HOST is successful or failure?
Thanks

Invoking a UNIX shell command from Java stored procedure

The program below is suppose do send an email using UNIX mailx program. It works correctly when I compile it in UNIX and invoke it from the command line by sending an email to the given address.
I need this program to run as a stored procedure, however. I deploy it as such and try to invoke it. It prints the results correctly to the standard output. It does not send any emails, however. One other difference in execution is that when invoked from the command line, the program takes about a minute to return. When invoked as a stored procedure in PL/SQL program or SQL*Plus anonymous block, it returns immediately.
Why would mailx invocation not work from a stored procedure? Are there other ways to invoke mailx from PL/SQL?
Thank you.

System.out.println(mailx("Hey, there", "Hello", "oracle@solaris10ora", 1));

* @param addressee message addressee
* @param display if greater than 0, display the command

String addressee, int display)
System.out.println("In mailx()");
try
String command =
"echo \"" + message + "\" | mailx -r [email protected]" + " -s \"" + subject + "\" " + addressee;
if (display > 0)
System.out.println(command);
try
Process process = Runtime.getRuntime().exec("/bin/bash");
BufferedWriter outCommand =
new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
outCommand.write(command, 0, command.length());
outCommand.newLine();
outCommand.write("exit", 0, 4);
outCommand.newLine();
outCommand.flush();
process.waitFor();
outCommand.close();
return process.exitValue();
catch (IOException e)
e.printStackTrace();
return -1;
catch (Exception e)
e.printStackTrace();
return -1;

try adding the full explicit path to "mailx" in the command string that gets sent to Runtime. i would guess that the shell that gets spawned might not have a proper environment and thus mailx might not be found.

Call HOST command FROM FORMS 4.5 AND 6.0

I have a problem that I found out about yesterday, and have no idea how to fixe it.
I created a form to run on form 4.5.9.7 In this form i call up the host command, but it does not work properly, because by using the host oracle stops there until i close the application that i called with the host, it hangs there. But now it doesn't do it, once the host is executed, it continues the rest of the code that i have, which should not.
On the same computer i created another form on forms 6.0.5.2 and call the host command again, and finally it worked perfect! I mean until the program called by host command is running forms does not continue, it hangs there.
Could someone explains me that please, is there some patch I need on forms 4.5?
null

We converted forms from 4.5 to 6.0. Basically all you have to do is recompile the forms. but, the very first thing you have to do is recompile all the libraries. The forms will not work if you don't recompile the libraries first. So, open and compile the libraries in 6.0, then open and compile the forms in 6.0. They should then work fine. If they do not, try deleting and reattaching the libraries and compile again.
Good luck.

Running shell command from Java, but from Windows Schedule Task?

I have a simple java program that will start a dos based program. The java program works great when I run it, but when I run it from the Windows Task Scheduler, the dox box that should pop up, does not. It is running because I can see it in the task manager but I can not see the command window.
Any ideas how to show the command window from a java application that is ran from Windows Task Scheduler?
Example program below. Runs fine by itself, should get a dos popup that issues the directory command, run it from the scheduler and it does not show the dos box. You can however see it in the Processes as CMD.exe.
import java.io.IOException;
public class Test {
      * @param args
     public static void main(String[] args) {
          try {
               Runtime.getRuntime().exec("cmd /k start dir");
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
}Now the my real program is quite a bit more complicated. It actually goes out and checks the status of an Oracle Database, if all the tablespaces are online, then the middle tier application is allowed to start. The middle tier application is started by my java application, and is comes up with a dos console which shows status and users connected to the database.

Jag,
Actually, the question of whether it works for me seems to depend on the version of the OS (or Oracle). On RedHat Linux (Oracle 8.1.6) it didn't work at all, but on Solaris (Oracle 9.0.2) it did. Here's the output from that run:
SQL> /
output of the command run:
init.ora
initDBPart9i.DBPSun01.ora
initdw.ora
lkDBPART9I
orapw
orapwDBPart9i
spfileDBPart9i.ora
Done
PL/SQL procedure successfully completed.
But, I did need to change a line of your code to this:
Process p = Runtime.getRuntime().exec("/usr/bin/ls");
your original was:
Process p = Runtime.getRuntime().exec("ls");
You might consider, if possible, use of some of the Java File classes instead of ls, as this might make things more predictable for you. There were some examples in oramag.com a few months ago, but they were pretty simple (you might not need them).
Hope this helps,

But when I call cmdTest from SQLPlus using an Oracle stored procecdure it just hangs forever and I have to kill the session.
Is there something I am missing in the cmdTest method?

Jimmy,
If you haven't already seen it, I think the following article may be of help:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Also a "finally" block should not contain a "return" statement:
