More on unix script from pl/sql

Hi All,
There was this discussion on starting unix scripts from within a pl/sql stored procedure started on August 31.
All comments were targeted towards an oracle 8X solution.
Does anyone have a solution for 7.3.4?
Somebody mentioned something about using dbms_pipe package.
So, just to rephrase the problem:
- Need to execute any unix command/script from within a pl/sql block (stored procedure). Instance is oracle 7.3.4
Thanks!
Enrique

Hi Juan,
You can try this solution:
enable in the the init file the parameter
utl_file_dir="target_directory"In this way You permit the the DB to writing directly to the filesistem in the directory You specified.
After restarting the istance You may write Your own code that, using the supplied package UTL_FILE, writes a file in that directory (es. my_script.sh)
Then, instruct the cron daemon to execute every 1 minute this command.
You may append to the script the self-destruction after the execution.
I hope that this will help You.

Call a unix script from pl/sql package

Hi,
Using 11.2.0.3 on AIX.
Is it possible to call unix script from pl/sql package?
I am cretaing a file in a directory but would like this to automatically be written to an archive directory as well.
Could either use 2 utl_file.put_lines to 2 separate directories or 1 utl_file and cal script to archive file in another directory.?
Thoughts?
Thanks

Starting Unix Script from pl/sql procedure

I would like to start any unix shell script out of oracle.
I don't want use DBMS_PIPES, because then I always need a unix daemon.
Is there a package wich allows to a call similar to
"os_result := dbms_systemcalls.call_unix_system
('/usr/bin/ls -la');
null

What version of Oracle are we talking about here? If it's v8 then I think what you're after is a pl/sql external procedure which I can tell you how to set up.

How to pass arguments to a Unix shell script from PL/SQL?

We want to run a Linux shell script from PL/SQL (10g). This is our code to run the script only and it works fine.
dbms_scheduler.create_job
          job_name=>'RUN_LINUX_SCRIPT_' || v_job_name,
          job_type=>'EXECUTABLE',
          job_action=>'/vol0/FileLoadDir/Bank/DATA_FILES/spell_check.sh',
          enabled=>TRUE,
          auto_drop=>FALSE
        );Now we have a requirement to pass 2 arguments to the .sh file. In the .sh file the 2 arguments are defined as $1 and $2.
I used this method.
dbms_scheduler.create_job
          job_name=>'RUN_LINUX_SCRIPT_' || v_job_name,
          job_type=>'EXECUTABLE',
          job_action=>'/vol0/FileLoadDir/Bank/DATA_FILES/spell_check2.sh',
          --job_action=>'/vol0/FileLoadDir/Bank/DATA_FILES/spell_check2.sh /vol0/FileLoadDir/Bank/DATA_FILES/ebill2.fmt_form_strings_.txt /vol0/FileLoadDir/Bank/DATA_FILES/abcdefghij.txt',
          --job_action=>'#!/bin/bash spell /vol0/FileLoadDir/Bank/DATA_FILES/ebill2.fmt_form_strings_.txt > /vol0/FileLoadDir/Bank/DATA_FILES/abcde.txt',
          number_of_arguments => 2,
          enabled=>FALSE,
          auto_drop=>FALSE,
          comments => 'Testing by Channa'
      DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
        job_name                => 'RUN_LINUX_SCRIPT_' || v_job_name,
        argument_position           => 1,
        argument_value          => '/vol0/FileLoadDir/Bank/DATA_FILES/ebill2.fmt_form_strings_.txt');
      DBMS_SCHEDULER.SET_JOB_ARGUMENT_VALUE (
        job_name                => 'RUN_LINUX_SCRIPT_' || v_job_name,
        argument_position       => 2,
        argument_value          => '/vol0/FileLoadDir/Bank/DATA_FILES/abcdefghij.txt');
      DBMS_SCHEDULER.enable (name => 'RUN_LINUX_SCRIPT_' || v_job_name);But I get an error saying:
STANDARD_ERROR="/vol0/FileLoadDir/Bank/DATA_FILES/spell_check2.sh: line 4: read: `/vol0/FileLoadDir/Bank/DATA_FILES/ebill2.fmt_form_strings_.txt': not a valid identifier

Calling UNix Script from portal Form

Has anyone conquered this issue through jav or plsql. I need to call a unix script from the portal form when I select the insert button.

I have several very convoluted ways which all work, but I have always thought there should be more straightfwd ways. Fundamentally the easiest way to call something from the Insert button is to add some PL/SQL code before (or after) the "doInsert();" call in the Insert Button event handler.
What seems to be lacking is the ability to get from pl/sql to the o/s. So until we know how to do that you have to call a method in Java to execute o/s commands - specifically you can use Runtime.getRuntime().exec(cmd); where Runtime is a class in java.lang, and cmd is the actual o/s command (script or whatever).
How to call this Java is then where you have several options:
1. Compile this piece of Java into the Oracle DB as a SP.
2. Deploy this piece of Java within a Java servlet on a 9iAS instance. Then have another SP call this servlet using the utl_http package (begin_request and other sp's within package).
Which options would depend on several factors including your preference but most importantly whether you have a DB or a 9iAS instance on the machine where you want to execute the script. If you have neither you have a problem. In such cases I have used a standalone OC4J container which has a very small footprint.
As I said these methods are all quite convoluted and if anyone else has anything better I would like to know (but they work quite reliably).
Cheers.

How to run a unix script from oracle warehouse Builder

Hi,
can any one share the information about, running the unix script or scripts using oracle warehouse builder.
Regards,
Ak

One way is define a workflow. Inside the workflow you put
1)an external process that "points to" the shell script and then
2)put the mapping
The external process must have the "COMMAND" parameter set to the name of the shell script. If the script has parameters you must put them in the "PARAMETERS LIST" separated by "?" (for example, ?par1?par2).
The path where OWB executes the external process I think is the ORACLE_HOME of the OWB.
f you don't use workflow, you can try with this more complex solution. I tried with 9i and OWB 9.2 and it's working well.
You create an autonomous procedure (within a package or not) :
CREATE PROCEDURE Extract_Email_List
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
And use the sys.shell script that you need your dba/unix admin to install first of all, with a call like that.
sys.shell('sh ' || txt_dir_name || '/send_email_marketing.sh ' || txt_dir_name || ' ' || email_addr );
Then you import your procedure into OWB and use it in your mapping with the "pre-mapping" icon (you can set parameters for your proc with constants if you want).
To implement sys.shell, go to metalink and find "Note:168065.1" - "How to call a UNIX shell script from PL/SQL".
Once it's done once, it's not so bad. But I would still recommend the workflow approach also..
I hope this helps.

Executing Unix scripts from a stored procedure

From the sql*plus windows, I am able to execute the host command and '!sh' commands; but I need to ececute Unix scripts from a stored procedure. Hoe can I do this? Where can I get good documentation on this? Any help would be greatly appreciated!
Thanks..

Hi,
U can use external procedure ( newly added feature in 8.0.3 onwards) and call any shared library. From shared library u can execute it.
One sql command is there HOST(' '). U can run a OS command. But u can not use it in PL/SQL.
U can call pls sql from shell !!!!!..
Thanks...

Problem executing Unix script from Java...

Hi there, I'm having trouble executing a unix script from a java program. The script receives multiple parameters and it seems that one of them ( or more ) is not well interpreted. When I run the script directly from a shell, the script executes without any errors. But, when I run the exact same script with the exact same parameters, it does not work.
Here is the command to execute the script with all the parameters that is executed from the shell ( with success ) and also from the java program ( with errors ):
/z/opus/dcap/intfu001.csh 'NODEBUG^NOTKPROF^NOSTACK' opus dcap JACQUES JACQUES '2625781' 'ORA$PIPE$001D00D70001' JOB^DEBUG^SINISIMU^STATPROD^DECTIDANC^81^503^4080^86^87^151^97^98^99 BUT^N^N^SPRI^0^13^24^3^J^05^N^19^19^19 >> /tmp/switcher8.999.null.pgm.test
And here is my portion of code that executes the script:
Runtime wShell = Runtime.getRuntime();
Process wProc = wShell.exec(cmd_unix_final);
wProc.waitFor();
return wProc.exitValue();
Please give me your thoughts on this!
Thanks in advance!

Ok.
Let's proceed surgically, else we'll never solve or overcome anything.
In the last your reply you wrote:
the normal output is what I get when the script runs successfully, the script first prints a few things
and then does stuff that takes at least 2 or 3 secondsWhat do you mean?
-Finally have you got your script correctly executed?
The stuffs you spoke of are really performed?
If this is the case I can't see the prob.
Is your concern only about exitValue() for it doesn't let you distinguish programmatically
the success or failure of the script execution?
Of course you surely already have a routine in your java code to handle
exceptional situations of errors from the script.
And the "normal output" is just what you must parse to detect those errors.
Then who cares about exitValue() in this case?
Don't invoke it, relay on the stdout and stderr of the script.
-Or you get only a deceiving standard output
that let you think the script execution went alright, while instead it didn't.
In this case we have to investigate some other thing.
I can't still exclude that the problem isn't related with the buffer size of the stdout
allocated by the environment to the subprocess. You spoke of few things printed out.
Be explicit. What's the size of the output you get?
And is the "normal output" complete till the very last char
or is it truncated from somewhere on?
Also it's important that you hit a ps command after the java main process terminates
(or simply when waitFor() returns) and see if the script subprocess hung up.
As an alternative approach directly call your pro*C code from Java through JNI, instead of translating it.
1. Exec.java
public class Exec{
     static{
          System.loadLibrary("Exec");
     public static native void proCFunct();
     public static void main( String[] args){
          proCFunct();
}2. javac Exec.java
3. javah Exec
4.Exec.c
#include "Exec.h"
JNIEXPORT void JNICALL Java_Exec_proCFunct(JNIEnv * a, jclass b){
     //here call the function that executes the script
5. cc -G -I$JAVA_HOME/include -I$JAVA_HOME/include/solaris -I$YOUR_INCLUDES Exec.c -o libExec.so
6. setenv LD_LIBRARY_PATH .
7. java Exec

How to run a Unix Script from a specific user

Hi,
I want to run a GoldenGate related unix script from a super user. I have created crontab enter from that super user. But its still running from root user. As GGSCI cannot be invoked other than super user, the Script is failing.
The Script is running fine on command prompt and from "at" batch job command.
Please give me a way to run the script from a specific user on Cron
Thanks,
Saravana

Hi.
can you show:
grep root /etc/passwd
grep <super user> /etc/passwd (It's not clear for me, what you call super user. For me - root is super user. )
ls -la /var/spool/cron/crontabs
Generaly for add cronjobs for any user need:
crontab -e <username>
For more information - man crontab

Unix Scripts and PL/SQL

I want to run a UNIX script via PL/SQL. I want the script to be run with no assistance from an outside source. The script contains a 'ls'. Is this possible and if so, how.

<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Christopher Racicot ([email protected]):
You can use an "external procedure", written in C, which then uses the C runtime library to access the UNIX shell. This features is

Calling Pearl script from PL/SQL

Anyone know how to call a pearl script from PL/SQL?

Hi Rick,
I checked all the forums for external procedures. I don't see any examples posted as you mentioned for calling external procedures. I did look into the documentation and it talks mainly about C and JAVA. And it looked like depending on the language, different things need to be done. I would appreciate if you could be more specific on where I could find examples related to calling PERL scripts.

How can i run unix script from my apex page

how can i run unix script from my apex page and take the output of unix script as a hidden variable and display it on the report region of that page

I had a requirement to run a Fortran program against some data that woudl be extracted from the database after the user set up their filtering criteria and made some additional input. SInce the program was to complex to conver to PL/SQL, we decided to try and invoke it from Apex. This is how I did it.
1. I followed the steps in Tim Archer's excellent article "Oracle External Procedure to Run Host Commands" (http://www.timarcher.com/?q=node/9). If the link does nto work, google the article's title.
Using this steps I created a function which accepts any OS command, including calling my own shell scripts, and runs them. I called my PL/SQL function "shell" instead of "USF_RUN_HOST_CMD " as Tim did in his example (step 9).
2. In Apex,
a. I created a button to run my shell command. (I named it P2_RUN_SHELL)
b. I created a PL/SQL process whose source looks as follows:
shell('/home/ackness/scripts/cr_xcf_file.sh > /tmp/cr_scfp_file.log');
and which was conditioned on the the button P2_RUN_SHELL.
It works like a charm.
Note: since you can run your own scripts using this method, you can encapsulate a series of commands in a UNIX shell script and invoke that script from Apex. This allows you to be able to test or run you commands from the command line as well as Apex and makes it easier to develop/debug/enhance the scripts in the future.

Copying SQL Script from Oracle SQL Developer into Excel with formatting

I need to copy a SQL Script into Excel in order to develop some VBA code. Is there any nice way that I can copy SQL Script from Oracle SQL Developer into Excel and retain its formatting? I am a stickler for having legible, readable SQL and like to have all my columns lined up and aliases lined up. When we used to use SQL Navigator, the tab formatting seemed to copy and paste just fine. Now that we have migrated to Oracle SQL Developer, the formatting seems to get all messed up.
And suggestions are greatly appreciated and Thanks in advance for your review and am hopeful for an answer.
Thanks.
PSULionRP

I suppose you want a real tabulator instead of spaces. You can configure this in the preferences (SQL Formatter - Oracle). You have to apply it then to your existing code (e.g. CTRL-F7), but new code should get it right from the start.
Hope that helps,
K.
