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.

Calling shell script from stored procedure.

Hi Everybody,
Could anyone tell me how to call a shell script from a stored procedure.
Thanks,
Vasu

You would need to write a Java stored procedure that calls out to the underlying operating system. Tom Kyte has an example of this here
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:952229840241
Make sure that you're very aware of the security implications here, however. Your commands will run as the Oracle user on the host operating system, which makes it possible that a coding error and/or an attacker could do something like delete or corrupt Oracle data files, so you'll probably want to harden the code substantially.

11g - calling shell script from trigger

From what I read so far, starting from 11g onward user credential IS REQUIRED in order to call the shell script from database procedure/trigger. I am working in a shop where they used SSO (so no password) and having a local user with password is not possible.
I wonder if anyone used any other method to call the shell scripts from database procedure/trigger?
Thanks all

performance is not going to be a problem for this requirement b/c it ONLY happened after the startup or before the shutdown.
That still -- even more so --- sounds like a bad idea. Exactly what does this shell script accomplish that needs to be triggered by database startup/shutdown?

Can we call shell script from oracle 9i?

Hi experts,
I wanted to know can we call shell script from oracle 9i procedures? If yes,how
Thanks
Shaan

No. I can't think of a way to do this...
If you want you can use DBMS_SCHEDULER to call OS SHELL scripts within.
For e.g.
CREATE PROGRAM
begin
dbms_scheduler.create_program
program_name => 'CHECK_TIME',
program_type => 'EXECUTABLE',
program_action => '/opt/oracle/chk_date.sh',
enabled => TRUE,
comments => 'Check the Time'
end;
CREATE A SHELL SCRIPT
opt/oracle> cat chk_date.sh
#!/usr/bin/ksh
echo "The date is :`date`"
CREATE SCHEDULE
begin
dbms_scheduler.create_schedule
schedule_name => 'EVERY_30_MINS',
repeat_interval => 'FREQ=MINUTELY; INTERVAL=30',
comments => 'Every 30-mins'
end;
CREATE JOB
begin
dbms_scheduler.create_job
job_name => 'RUN_CHECK_TIME',
program_name => 'CHECK_TIME',
schedule_name => 'EVERY_30_MINS',
comments => 'Run the program CHECK_TIME every 30 minutes',
enabled => TRUE
end;
MANUALLY RUN A JOB
exec dbms_scheduler.run_job('RUN_CHECK_TIME');

Calling shell script from apex application

Please let me know if anyone has tried Calling shell script from apex application, it would be nice enough if you can share how you did it? Thanks

Hi,
Requirements
* CREATE JOB (10g Rel.1)
* CREATE EXTERNAL JOB (10g Rel.2 / 11g)
* EXECUTE on dbms_scheduler (granted to public by default)
Since Oracle 10.2.0.2 the commands are executed as user nobody.
Code:
--Create a Program for dbms_scheduler
exec DBMS_SCHEDULER.create_program('RDS2008','EXECUTABLE','c:\ WINDOWS\system32\cmd.exe /c echo 0wned >> c:\rds3.txt',0,TRUE);
--Create, execute and delete a Job for dbms_scheduler
exec DBMS_SCHEDULER.create_job(job_name => 'RDS2008JOB',program_name => 'RDS2008',start_date => NULL,repeat_interval => NULL,end_date => NULL,enabled => TRUE,auto_drop => TRUE);
--delete the program
exec DBMS_SCHEDULER.drop_program(PROGRAM_NAME => 'RDS2008');
--Purge the logfile for dbms_scheduler
exec DBMS_SCHEDULER.PURGE_LOG;
This is one way as suggested by Trent.
We can also achieve as follows.

Call Shell Script from PL-SQL

Hello All,
I have been using some well known Java Class and Procedures to execute shell scripts from PL-SQL.
The different environments I was using before were
1)
Operating System (Server) AIX version 5
Oerating System(Client) Microsoft Windows XP Service Pack 2
Oracle Database Version Oracle Database 10g Enterprise Edition Release
10.2.0.1.0
2)
Operating System (Server) Red Hat Linux 3.4.5-2
Oerating System(Client) Microsoft Windows XP Service Pack 2
Oracle Database Version Oracle Database 10g Enterprise Edition Release
10.2.0.1.0
But suddenly I had to drop and recreate the Databases on 1st (AIX) environment
and
reinstall the Operating System (Server) Red Hat 3.4.5-2 on IInd environment stated above (which obviously means the reinstallation of Oracle Database there!)
Now the shell script(through PL-SQL)is executing smoothly for the IInd (Linux) environment[b] but not executing for the Ist (AIX) environment
and I am not getting how to solve the problem.
I have given all the permissions to users, shell scripts and all as they were before.
Can you please help?
Regards,
Abhijit.

Calling shell script from forms9i

Hi,
I have a shell script that inserts records in the table. When I run this shell script in Unix, it runs fine and inserts records in the table.
But when I run it from forms9i by using HOST command it does everything written in the shell script but inserting records in the table.
Can anyone tell me why it is not inserting records in the table.
I will really appreciate you response.
Thanks,
Kumar

IMO when you run the shell script from forms it runs in privileges of App server user and in that shell that why its running as oraias when you run it from forms .. I think the SSO is out of picture in this situation.So you need to find a way of connecting to the in the script.
Check the TNS names environment varaibles etc for doing this,

Calling shell scripts from within Oracle PL/SQL codes

Hello,
We are migrating from informix to Oracle. In our Informix Stored Procedure we
were able to call Unix Shell Script by executing a 'SYSTEM' command, such as:
CREATE PROCEDURE magazine(flag1, flag2)
SYSTEM '/pics2/informix/mag.sh' || flag1 || flag2;
END PROCEDURE;
How can I write this in PL/SQL? Is there a simillar command for 'SYSTEM' in PL/SQL?
Thanks

Mike,
Wrong forum, for this question, suggest you ask it in the PL/SQL forum.

Call shell scripts from htmldb

Hi,
I've a requirement to check for the existance of a file in Linux server using htmldb. The problem is html db is installed on a different machine. Is there any way I could execute shell scripts in html db that connects to the linux server and checks for the file existance?

Andy,
The general answer is: whatever you can do from SQL or PL/SQL can be run from an HTML DB process. So to output to the server you might use utl_file. There are several ways to run external commands, you might start by searching for 'shell' on askTom.

Calling shell script from udev rule

Hello,
I've encrypted partition with key stored on usb drive. I created udev rule:
SYSFS{size}=="....", SYSFS{serial}=="....", ACTION=="add", SYMLINK+="pendrive", RUN=="/bin/sh /home/kamil/bin/cryptsetup.sh"
as You can see I would like to call cryptsetup.sh when pendrive has been inserted. This script looks like:
/bin/mount /media/pendrive
/usr/sbin/cryptsetup luksOpen /dev/sda7 enc1 -d /media/pendrive/key.txt
/bin/mount /mnt/enc1
The idea is to create /dev/mapper/enc1 and mount it automatically without any user action. My problem is that second line of this script (cryptsetup command) hangs for a long time - minute or two.
Here, if it helps, is the listing of processess when cryptsetup hangs:
ps ax | grep crypt
1379 ? S< 0:00 [kcryptd/0]
6418 ? S< 0:00 [kcryptd/1]
8046 ? S< 0:00 /usr/bin/perl /home/kamil/bin/cryptsetup.sh
8049 ? S<L 0:01 /usr/sbin/cryptsetup luksOpen /dev/sda8 enc2 -d /media/pendrive/key.txt
8098 pts/2 S+ 0:00 grep crypt
Notice status of command /usr/bin/cryptsetup... - it's S<L. I don't know if it is connected to the problem.
When I comment out this udev rule, connect the pendrive and than manually call cryptsetup.sh I have no problem and everything works fine.
Any ideas how to fix that?
Thanks, best regards
Kamil
