Call a unix command

Hi Community,
It's possible to create a program that a call does a unix command.
I would like created a synchronous scenario.
Then the program call a unix command and this is waiting up to when a unix command termined a runtime.
The command returned a data and the ABAP program will owe to take back the esecution.
I hope in you
Thank's everybody.

Hi Antonello,
i'd do it with different job steps (SM36)
1) Program1, which does a unix command:
syntax:
CALL 'SYSTEM' ID 'COMMAND' FIELD COMMAND
ID 'TAB' FIELD TABL-SYS.´
or have a look here: external commands
2) Program2 handle the output (e.g. a file) of program 1

Can I use samba in order to call commandYes, smaba supports "magic" files that cause a program to be executed when they are accessed. Note, this does not provide for arguments but you can put these in a file which you command reads.
or is there any way to open an telnet session within java applicationYes. just use a Socket connection.

2.sql stmnts of insert etc
/OR
use sqlldr for the same.
done.
** how do i do both the operations 1&2 in the same Oracle procedure?

I know HOST can be used in form for OS command but I never thought about doing OS command in the stored procedure.

Calling unix command in Apex Window

I am working on a small project where in; it would be handy to run an external plsql in oracle database which calls for unix command such as tail -f alert.log or tail -1000 alert.log when a button is pressed in the application.
I know the client and server aspect and very difficult to forward the server output to Application specially web based but still thought of trying my luck to get some insights from this forum .
Is this possible in Apex ?
UK

Don't see why not. All the building blocks are there (assuming a recent version of the database, and that 1000 is a realistic metric of the data volume):
1. A script to run the required UN*X commands.
2. An initial log extract file created manually using the script.
3. An external table on the log extract file.
4. An external scheduler job to rerun the log extract script to refresh the log extract.
5. An APEX page with a report based on the external table, and a button that calls the external job.
Note that providing relevant information when asking a question is helpful in determining a solution:
- APEX version
- DB version and edition
- Web server architecture (EPG, OHS or APEX listener)
- Browser(s) used
- Theme used
- Templates used

Yes, at the begining, I'll tried the unix shell by calling SQL.
I've the problem of passing the parameters through.
It seems to me
we can use
Host in the SQLPLUS to run the unix command.
but I've written it in my sqlplus script, it doesn't work. so I wanna to find an exemple how to use HOST in sqlplus script?
I would have loved to give you an example..but its not unix on my laptop.
But what i can tell you is...u should be doing otherway round.
Not calling Unix commands from SQL but calling SQL's form unix.
You got shell scripts for that.
Write a shell script. Login to SQL execute your code.
exit from sql and then move your file with MV. That's it.
Do post how far you get after trying this.

Call an interactive UNIX command from java

Hi,
I want to call a UNIX command from java. When issue the command 'htpasswd -c filename username' on UNIX terminal, it asks for the new password and the then confirmation password again (yeah, unfortunately the htpasswd installed on our system does not allow you proivde the password on the command line. So have to work interactively ). Now, I have written a simple java program RunCommand.java. I am hardcoding the password for the htpasswd command in the file (in the real situation, password will be generated dynamically). I want to issue 'java RunCommand' on the UNIX command line and get back the command prompt without being asked for the password twice. The code is below, but the Outputstream does not work as expected. It always asks for inputs. Any idea? Many thanks.
import java.io.*;
public class RunCommand {
public static void main(String args[]) throws Exception {
String s = null;
try {
String cmd = "htpasswd -c filename username ";
// run a Unix command
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
OutputStream stdOut = p.getOutputStream();
String pswd = "mypassword";
while ((s = stdInput.readLine()) != null) {
     s = stdInput.readLine();
     stdOut.write(pswd.getBytes());
     stdOut.flush();
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
stdOut.close();
stdInput.close();
stdError.close();
System.exit(0);
catch (IOException e) {
System.out.println("exceptions caught: ");
e.printStackTrace();
System.exit(-1);

Calling UNIX command from PL/SQL Procedure

Is there a way to call a UNIX command (exa. ls) from within a PL/SQL stored procedure? Looking through the various packages, I didn't see anything that would give me this ability.
I also looked through all the previous questions and nothing looked encouraging.
Thanks in advance,
Russ

Russ,
I thought I'd read a similar question awhile ago and did a search on the word host in this forum and found the following from July 9th that might help you:
http://technet.oracle.com:89/ubb/Forum88/HTML/001611.html
In that post I think the link listed by Barbara Boehmer in has changed to:
]http://asktom.oracle.com/pls/ask/f?p=4950:8:24579::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:16212348050,{host}
It looks like they give solutions for Oracle 7, 8 and 8i.
Good site Barbara, I've added it to my bookmarks.
Hope this helps.

Unix command from pl/sql

How can I call a unix command or run a c program
from a stored procedure in oracle 9i.

Or if you want to do a host call then implement the following class as a Java stored procedure.
import oracle.jdbc.*;
public class util
// Executes an operating system command. The command shall be fully qualified.
// The Java connects with silent login. No environment set-up files are run
// and no path is set. The mode can be "sync" or "async" for respectively
// synchronous and asynchronous execution
static public int OSCmd(String cmd, String mode, String[] output)
throws IOException, InterruptedException
System.out.println("OSCmd "+cmd+" ("+mode+")");
output[0]="";
// start command
Process proc = Runtime.getRuntime().exec(cmd);
if (mode.equals("sync"))
// get command's stdout and stderr
InputStream stdout = proc.getInputStream();
InputStream stderr = proc.getErrorStream();
String str;
// Stdout
BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
while ((str = br.readLine()) != null)
output[0]+=str+"\n";
br.close();
// Stderr
br = new BufferedReader(new InputStreamReader(stderr));
while ((str = br.readLine()) != null)
output[0]+=str+Long postings are being truncated to ~1 kB at this time.

Unix command question on TAB content

We found the following ABAP statemenet
DATA: our_unix_path_and_file_name(64) TYPE c,
           v_unixcmd(255) TYPE c,
           result(255) TYPE c OCCURS 100 WITH HEADER LINE.
CONCATENATE 'ls -al' our_unix_path_and_file_name INTO v_unixcmd SEPARATED BY space.
CALL 'SYSTEM' ID 'COMMAND' FIELD v_unixcmd
                ID 'TAB'     FIELD result-*sys*.
The question is: is result an internal table? if it's an internal table, then why it's defined as type c? And also what is included in this result after calling this UNIX command? it will list all the file content?
Thanks and we will give you reward points!

Hi,
The result you'll get is a list of files and attributes from a directory and it will be placed in an internal table.

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.

Shortdump while calling UNIX command

Hi all,
I have a problem while trying to remove a file in UNIX platform in ABAP program.
It is working fine in the development and quality server, but not in production server.
Based on the debug result, the shortdump was thrown while executing "CALL 'SYSTEM' ID 'COMMAND' FIELD lv_command".
Below are the message return in the program shortdump

    You can check the authorization beforehand with the
    function module AUTHORITY_CHECK_C_FUNCTION.

Anyone knows why and how to resolve this?
Kindly provide your feedback and input. Thanks in advance.

You don't have authorisation in PRD to remove files. If it is really required for you.
Take SU53 screen shot immediately once you get short dump and follow up with Basis Folks for required authorisation.

Hi,
I have a problem with synchronization of the java commands.
In the Before Parammeter Form trigger, I have:
function BeforePForm return boolean is
rt ORA_JAVA.JOBJECT;
proc ORA_JAVA.JOBJECT;
v_txt varchar2(32000);
i integer := 0;
v_cd_modulo int;
v_arqlog text_io.file_type;
cursor c_evento is
select codigo,
nome
from
(select e.cd_evento || e.cd_edicao codigo
,nm_evento nome
from grh_ev_evento e
where e.CD_GRUPO in (select cd_grupo
from grh_ev_adm
where cd_usuario = (select cd_usuario
from usuario
where login_usuario = :AUTHID)))
order by substr(nome, 11);
begin
-- Create the context for logged user
if instr(upper(nvl(:AUTHID,'RWCLIENT')),'RWCLIENT') > 0 then
:AUTHID := :SSO_USUARIO;
end if ;
TCEENV.SET_TCEENV(:AUTHID);
if PK_SCA.SCA_GET_USER_RIGHTS(:sca_module_name, :AUTHID) IS NULL then
srw.message(100, 'Access denided!');
return (FALSE);
end if;
-- Create file in Report Server (UNIX)
v_txt := '<BR>' || htf.formSelectOpen('P_EV_EDICAO', 'Evento: ');
:p_file := '/u03/SCAWEB/repout/' || :sca_module_name || '_' ||
pk_sca.sca_encrypt(:AUTHID || to_char(systimestamp, 'ss.ff'));
v_arqlog := text_io.fopen (:p_file, 'A');
text_io.put_line (v_arqlog, v_txt);
for reg in c_evento loop
i := i + 1;
if i = 1 then
v_txt := '<OPTION SELECTED VALUE="' || reg.codigo || '">' || reg.nome;
else
v_txt := '<OPTION VALUE="' || reg.codigo || '">' || reg.nome;
end if;
text_io.put_line (v_arqlog, v_txt);
end loop;
v_txt := '</SELECT></CENTER></form></BODY> </HTML>';
text_io.put_line (v_arqlog, v_txt);
text_io.fclose (v_arqlog);
SRW.SET_AFTER_FORM_HTML(SRW.FILE_ESCAPE, :p_file);
rt := RUNTIME.GetRuntime();
proc := RUNTIME.exec(rt,'rm ' || :p_file);
return (TRUE);
end;
The problem is that there isn't a "synchronize" command, and the
RUNTIME.exec(rt,'rm ' || :p_file) don't works (it does nothing) because
the SRW.SET_AFTER_FORM_HTML has a large delay and the following
command is ignored.
How can I solve it?
thanks,
