Runnings Shell Commands in PL/SQL Procedure

Hi folks,
I want to run the SQL/Plus HOST command within an PL/SQL Procedure.
I tried it with "EXECUTE IMMEDIATE 'HOST ls -la';"
and I'm afraid, that it didn't work.
Has anyone of you a suggestion?
regards
Markus

you can use system library.
Example for UNIX:
<<< create library in DB >>>
SQL>create or replace library libc
as
'/lib/libc.so';
<<< create procedure >>>
SQL>create or replace function libc_system (
cmd_str in varchar2
) return pls_integer
as external
library libc
name "system"
language c
parameters (cmd_str string);
<<< use it! >>>
SQL>exec libc_system('/usr/bin/cp /home/myhome/thefile /export/myfiles/thefile1);
NOTE1: You are need to be a familiar with "extproc" feature...
NOTE2: sometime(or always) you are need to put full path to executable files, like: "/usr/bin/cp"
I didn't checked a usage of env variables, like: $HOME, $ORACLE_HOME, etc...
NOTE3: This way can't be used to return a "screen" info from the function, like: "cat file1.txt | grep SOMETHING ".
For this case you can use utl_file package, like: "cat file1.txt | grep SOMETHING > file2". After that you can use utl_file package to read file2...

  • Shell commands in pl/sql

    Hi i´m having trouble using this:
    http://asktom.oracle.com/pls/ask/f?p=4950:8:6113176678923179734::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:16212348050
    the code i used is:
    create or replace procedure host( cmd in varchar2 ) as
    status number;
    begin
    dbms_pipe.pack_message( cmd );
    status := dbms_pipe.send_message( 'HOST_PIPE' );
    if ( status <> 0 ) then
         raise_application_error( -20001, 'Pipe error' );
    end if;
    end host;
    I've granted the privileges to run dbms_pipe, BUT when i try to use it, it gets stuck while trying to run :
    exec host('ls -l')
    it doesn't respond....
    then i tryed the part where it uses a shell to see what the procedure is doing, the code is:
    #!/bin/csh -f
    sqlplus tkyte/tkyte <<"EOF" | grep '^#' | sed 's/^.//' > tmp.csh
    set serveroutput on
    declare
    status number;
    command varchar2(255);
    begin
    status := dbms_pipe.receive_message( 'HOST_PIPE' );
    if ( status <> 0 ) then
    dbms_output.put_line( '#exit' );
    else
    dbms_pipe.unpack_message( command );
    dbms_output.put_line( '##!/bin/csh -f' );
    dbms_output.put_line( '#' || command );
    dbms_output.put_line( '#exec host.csh' );
    end if;
    end;
    spool off
    "EOF"
    chmod +x tmp.csh
    exec tmp.csh
    I supose it runs ok, becouse it creates a file named tmp.sch, but i can't really be sure becouse the previous part can't be done.
    another question is that what does tom mean when he says "running this in the background", do i have to do it o does it do it itself.
    what i need to do with this is send a file trough ftp, i've been using this shell named A-ftp.txt:
    ftp -v -n 10.128.0.89 << EOF
    user username password
    bin
    put "$1"
    bye
    EOF
    where $1 is the name of the file. so when i try it trough my procedure it would be:
    exec host('A-ftp.txt name-of-file')
    but it olso gets stuck. I need this urgent!!!! what is the problem??? is there another solution to my problem?? is dbms_pipe the only way???
    the code is the same as in the web page were i retrieved it, so i need to be given instructions in what to change and what to leave it as it is.
    Restrictions:
    I can only use pl/sql
    I have little time
    Thank You in advance

  • 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.
    Michael
    import java.io.BufferedWriter;
    import java.io.IOException;
    import java.io.OutputStreamWriter;
    public class MailUtility
    public static void main(String[] args)
    System.out.println(mailx("Hey, there", "Hello", "oracle@solaris10ora", 1));
    * Sends a message using UNIX mailx command.
    * @param message message contents
    * @param subject message subject
    * @param addressee message addressee
    * @param display if greater than 0, display the command
    * @return OS process return code
    public static int mailx(String message, String subject,
    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.

  • 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:

    It looks like they give solutions for Oracle 7, 8 and 8i.

  • Fire OMB Plus commands from PL/SQL

    Hi all,
    does anyone know if it is possible to fire OMB Plus commands from PL/SQL procedures?
    I can imagine that there might be a PL/SQL package in the repository owner schema that accepts OMB Plus commands as strings...or something similar...
    Thanks,
    Elio

    Hi Elio
    I don't know about any existing package that could do that.
    What I'd suggest is to build a stored procedure/function/package that could do that. Or even, execute OMB Scripts in the host from a pl/sql program.
    Good luck.

  • Calling shell script from sql procedure

    Hi gurus
    Is it possible
    1)to call a shell script from sql procedure
    2)that shell script has to return one value
    3)and again sql procedure(calling shell script) has to capture the return value.
    please help me to write this script

    You may NOT have EXECUTE privilege/ permissions on the DBMS_PIPE package. Check with your DBA.
    Using DBMS_PIPE may not be that simple to implement. Just making a call to DBMS_PIPE procedure will not do anything. It will NOT trigger anything on the UNIX side.
    . You will also need to :
    1.     Write a job (ie CRON) at UNIX side which will keep read the incoming pipe for new messages, Unpack the message and get the command to be executed at the UNIX side -- There will be a lot of work involved here + DBA presence/activity is also required.
    As Justin has pointed out, try and use HOST command which is very simple or try and use Java.

  • PL/SQL Procedure Calling Java Host Command Problem

    This is my first post to this forum so I hope I have chosen the correct one for my problem. I have copied a java procedure to call Unix OS commands from within a PL/SQL procedure. This java works well for some OS commands (Eg ls -la) however it fails when I call others (eg env). Can anyone please give me some help or pointers?
    The java is owned by sys and it looks like this
    CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "ExecCmd" AS
    //ExecCmd.java
    import java.io.*;
    import java.util.*;
    //import java.util.ArrayList;
    public class ExecCmd {
    static public String[] runCommand(String cmd)
    throws IOException {
    // set up list to capture command output lines
    ArrayList list = new ArrayList();
    // start command running
    System.out.println("OS Command is: "+cmd);
    Process proc = Runtime.getRuntime().exec(cmd);
    // get command's output stream and
    // put a buffered reader input stream on it
    InputStream istr = proc.getInputStream();
    BufferedReader br = new BufferedReader(new InputStreamReader(istr));
    // read output lines from command
    String str;
    while ((str = br.readLine()) != null)
    list.add(str);
    // wait for command to terminate
    try {
    proc.waitFor();
    catch (InterruptedException e) {
    System.err.println("process was interrupted");
    // check its exit value
    if (proc.exitValue() != 0)
    System.err.println("exit value was non-zero: "+proc.exitValue());
    // close stream
    br.close();
    // return list of strings to caller
    return (String[])list.toArray(new String[0]);
    public static void main(String args[]) throws IOException {
    try {
    // run a command
    String outlist[] = runCommand(args[0]);
    for (int i = 0; i < outlist.length; i++)
    System.out.println(outlist);
    catch (IOException e) {
    System.err.println(e);
    The PL/SQL looks like so:
    CREATE or REPLACE PROCEDURE RunExecCmd(Command IN STRING) AS
    LANGUAGE JAVA NAME 'ExecCmd.main(java.lang.String[])';
    I have granted the following permissions to a user who wishes to run the code:
    drop public synonym RunExecCmd
    create public synonym RunExecCmd for RunExecCmd
    grant execute on RunExecCmd to FRED
    grant javasyspriv to FRED;
    Execute dbms_java.grant_permission('FRED','java.io.FilePermission','/bin/env','execute');

    The output is as follows:

    Both commands do work when called from the OS command line.
    Any help or assistance would be really appreciated.
    Regards,

    Kamal,
    Thanks for that. I have tried to use getErrorStream and it does give me more info. It appears that some of the commands cannot be found. I suspected that this was the case but I am not sure about how this can be as they all appear to reside in the same directory with the same permissions.
    What is more confusing is output like so:
    SQL> Set Serverout On size 1000000;
    SQL> call dbms_java.set_output(1000000);
    Call completed.
    SQL> execute RunExecCmd('/usr/bin/id');
    OS Command is: /usr/bin/id
    exit value was non-zero: 1
    id: invalid user name: ""
    PL/SQL procedure successfully completed.
    SQL> execute RunExecCmd('/usr/bin/which id');
    OS Command is: /usr/bin/which id
    /usr/bin/id

  • Pl/sql procedure with shell script

    Hi Guys,
    I will be updating some of the columns in the database thru SQL UPDATE stament. I want to make this process automatic. I.e instead of running manually this uodate process, i want to write a unix script which run on cron job. In the update stament I have to compare date like e_create_date > to_date (........, 'yymmdd') and date should be 2 days previous then to date and I would ike to create the spool file which I would like to send through mail.the script will run automatically.
    I am confused how to write shell script & sql procedure and how to call it inside the shell script. How can this be done.
    Help Appreciated.
    Thanks
    sonu

    save the Store procedure as a create_SP.sql in OS
    save another testrun.sql
    as follows
    begin
    sp_test('&p_test');
    end;
    If you are on a Unix or Solaris OS then
    open a Shell Script as follows :
    and name as test.sh or test.ksh
    var='SYSTEM'
    export var
    sqlplus username/password
    @create_SP.sql
    -- this created a store procedure on the database
    @testrun.sql $var
    This will execute the SP with parameter from OS Variable.

    Alternatively you could create a PL/SQL procedure that wraps a Java Runtime object.
    You can find an example of this in the Ask Tom column of Oracle Magazine. You can get there from OTN home page. Type "Java Runtime" into the Search Archive engine.
