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 Unix Command From Reports Using Java

Hi,
Could somebody please show me a sample coding to call Unix command from 10g report using java?
In metalink doc id 361857.1 does not show much.
Thanks,

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 := ' ' || 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,

ASAP:stored proc calling Unix commands

i want an Oracle stored procedure to call unix commands as well as do sqlldr ... opern.
requirement is :
the stored procedure needs to do :
for all files in a Directory:
do
{ .. use sqlldr to insert data in tbls
.. move the processed file into another directory
so,for ls &mv commands i need the Command/way out.

Hi Jorma,
It's been a while since I did it, but I successfully did what you
are trying to do. All I did was "load" the remote interface and
"stub" class into the database using the "loadjava" utility. My
environment was Oracle 8.1.7 on SUN (Sparc) Solaris 7.
Although I haven't tried it, you may be able to invoke a servlet
from your java stored procedure. The advantage over RMI is that
you don't need to generate and load a "stub" class. Naturally, you
would use the "java.net.URLConnection" class to invoke a servlet
on some web-server/servlet engine which you can communicate with
using "streams" -- java.io.InputStream and java.io.OutputStream
Also, I understand that there is now a "oc4jclient.jar" (not 100%
sure of the name) file that can be "loaded" into the database,
which allows you to contact EJB's in Oracle's OC4J product. I
think you can either do this directly, or indirectly using JMS
over Oracle AQ.
[JMS = Java Messaging Service]
[AQ = Advanced Queueing]
Good Luck,
Avi.

Call unix commands from stored procedures

My stored procedure requires to call unix commands HOW DO I DO IT?
null

i do not know pl sql but in java you can use:
Runtime.getRuntime().exec("YOUR UNIX COMMAND");
real example:
Runtime.getRuntime().exec("ls");
but you must be careful with using that...
especially if you want to wait till the process finishes..
rgds,

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

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.

Calling Unix command from the plsql

Hi ,
I am executing java code from the UNIX Shell script. Before executing this command i want to write plsql code to and pass the files to java command.
In the plsql code i want to select request id's using the cursor and find the .out files for each request id in the outfile path. once the file is found i want to copy that .out file to the current directory where the java command is going to execute.
Please suggest me how to use UNIX Command (in my case "cp") to copy the .out file from the outfile path to current directory after opening the cursor.

If I understand you correctly, you want to generate a log of request id's from the database and send this to the operating system whereby you will execute the following:

java org.apache.xalan.xslt.Process -XSL combinedfsg.xsl -OUT output.xml

If that is correct, then you should be able to perform all of this w/ PL/SQL by generating the log from the database and write it to the O/S w/ UTIL_FILE. If you want to execute the java code at this point, you should be able to utilize Tom's method with the following:

exec rc('java org.apache.xalan.xslt.Process -XSL combinedfsg.xsl -OUT output.xml');

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.

Calling UNIX Command from another server using ODIOScommand utility

Hi,
My unix script 'runmanger' is on another server say 'St23456wer' under /u10/DV2/ofsaa/fic/xxx/bin. I want to call this 'runmanager' using ODIOSCommand. My ODI agent is installed on different server. I can ping 'St23456wer' server from ODI server. How can I call this unix script.

My only experience with this is connecting to source files on a remote linux server and the two options I was presented with were 1) creating a mount to make the files 'local', or 2) set up a new agent on the remote server.
One of the gurus may have a better answer for you.

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);

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

How to call unix script/command in ODI

Hello Gurus,
Please let me know how to call unix script/command in ODI?
Thanks
Shridhar

you can call shell script using the OS command found in Package.
Step 1. Drag the OS Command in the Packgae
Step 2. In the Text mentiond call the script say for ex sh /opt/path/script.sh
Step 3. Execute.
Note : Make sure the User through which ODI is triggering does have the required permission to execute shellscript , also always provide the full path , since scripts are execute from the oracldi/bin folder so its necessary to provide the complete path of the script location.
Hope this helps.
