Unix command using in pl/sql

Hi all,
Can we use unix command in pl/sql statement..
Regards,
Manikandan.k

Hi Manikandan,
You cantry this via Oracle Database Jobs. You can create a Job that uses your Shell Script & then execute the job in a procedure / function. It's one of the ways to access the underlying Operating System via PL/SQL.

Unix command into a pl/sql script

Could you tell me how to run a unix command (cp, rm, mkdir....)
into a pl/sql script ?

sigh this is an old chestnut. it can only be done using a java stored procedure. the instructions for doing this can be found in old postings on this forum - use the Search facility. alternatively try the AskTom site, and Metalink posted a solution as well.

Running unix command using java shows error

Hi All,
I am trying to run UNIX move command using Java exec method but its throwing error, unable to rename. Here below is the code i am trying to run to move all files from one directory to another directory. source and destination directory exists.
public class Demo
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("mv /home/demo1/* /home/demo2");
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}if i give "mv /home/demo1 /home/demo2" in exec method, its working, with * character its giving problem.
Please help me in resolving the problem.
Thank you

Characters like *, >, &, |, etc. are interpreted by the command shell--that is by the bash, zsh, etc. programs. When you execute a command with ProcessBuilder or Runtime.exec, you're not going through one of those shells, so their interpretation of those characters is not available.
In your code, the character * is being delivered directly to the mv command (which doesn't think * is anything special), as opposed to being turned into a list of files and directories as it would be when it's interpreted by the shell. The mv command doesn't know anything about the * character being special.
If you want to have those shell interpretations, you need to execute the command through a shell. One example is like so, but a) you'll want to read up on the methods in exec() that take arrays of String, and b) you'll want to read up on ProcessBuilder, and c) you'll need to check your shell's man pages to see the exact syntax and arguments.
runtime.exec("/bin/bash -c 'mv x/* y'");

Help with 2 UNIX Commands using ARD

Hello All,
Can someone help me with 2 UNIX commands I would like to set up? The first one... how to delete a range of users within /Users by date (i.e. the oldest user who last logged in "Mar 22 09:40 00796216" to "Mar 25 17:01 01036773"). Currently, I'm using "sudo rm -r " followed by each home directory name separated by a space. It works but to save time, it would be nice to do this all within 1 UNIX command.
Second, is there a UNIX command where I can delete a range of users by ID numbers? (We have users assigned with an 8 digit ID number. Is there a UNIX command where I can delete users from 12345678 to 23456781?) Again, I'm using "sudo rm -r " followed by each home directory name separated by a space.
Thank you in advance!
Mike

This happens with or without SIM card, with and without wifi... with and without SD card as well-- even bought a new 32GB class 10 SanDisk-- but it still crashed.
Just an update: Went to the Nokia Care Center yesterday, they reflashed the firmware and I got back the phone within the day... when I went back home to try the phone again... again it kept hanging... in a period of 5 minutes, I had 5 hangs... right from startup, went straight to the cam, took some pics then pinched zoom... and phone simply crashed-- had no SD car, no sim card then.
So today I went back to Nokia Care Center... they said they will do some more tests and see... but they insist its a software problem, we'll see in a day or 2.

Invoke and Execute Unix command from Oracle PL/SQL

Dear All,
I am currently working in the development of multi user application in ORACLE.
My problem is,
I have to remove a temporary file created in unix server when a particular condition is satisfied in a PL/SQL proccedure.
I searched for this and got solution to use DBMS_PIPE package.
Can you help me how to pack the content 'rm file_name' from different users working in different sessions and how to execute. Can you please explain me how the server manages calls from different sessions and replies to individual sessions.
Thanks in advance,
Shenbaga.

Well if doesn't raise an exception it succeeded. Is that sufficient acknowledgement?

SFTP using Unix command

Hi all,
I am trying to upload a file from SAP to a folder in another server.
Here they want us to use SFTP port 22 which is not supported by SAP by default i guess.
Could any one give me clear procedure and commands to be used in program in order to upload the in file in the server.
If you could give the methods and FMs and unix commands used it would be great.
I went through lot of threads but very few are talking about SFTP and i am not the clear about how to go with it.
Few say that we need to create and external command in SM59.
IF it is so can you tell what exactly are the parameter to be given for ex i want to put a file so what would be the parameters and how do we use this command in my program
Any sample code which puts the file another server???
Thanx

Check if your able to do sftp at command line from the server where BPEL is running.

How to run an applescript using unix command

Hi All,
Can any one help me in giving me the command for running an apple script thru postupgrade shell file in other words i wana run an apple script while running my new installer that will upgrade the old version of application but while installing i want to run an applescript so as i know ill have to give that applescript path in the postupgrade script but how to run it while installation and where to keep it (is it postupgrade). May be in short how can i run apple script thru unix command.

Use the osascript command.
In my installer, I use the DropDMG program to build my DMG disk image. It doesn't quit automatically, so I have to do the following:
osascript -e "tell application \"DropDMG\" to quit"
Type "man osascript" for more information.

Invoking Unix command with java stored procedure

Hi,
I have a perfectly working environment and now I am trying to replicate the same in another server. I have a java stored procedure which invokes the Unix command using java Runtime.exec() in my code named "run". I am sure that the code is called and the java class run is resolved in oracle as I could see that in dba_java_resolvers dictionary. But I am not sure whether the function in java is called or whether a exception is thrown. how to identify this? Could there be any thing to do with settings in oracle side? please help me.
Thanks in advance,
Marutha

Hi,
Do you get any output while running the code?
I'm testing similar solution and if there are any errors or Oracle can't execute the program due to permissions or other issues the error information will be displayed. Also in the Java class itself you need to catch exceptions and print stack trace to standard output.
declare
x number;
begin
dbms_output.enable(1000000);
dbms_java.set_output(1000000);
x:=system_command.run_command('testconnect.sh');
dbms_output.put_line('Returned value='||x);
exception
when others then dbms_output.put_line('Sql error='||substr(sqlerrm,1,250));
end;
<system_command.run_command> - replace with a call to your java stored procedure.

Newbie: how to temporary results and handle sessions running UNIX commands?

Hello,
I have just asked a question concerning launching UNIX commands using Java classes, see thread "_https://forums.oracle.com/forums/thread.jspa?threadID=2429211&tstart=0_".
I have followed the mentioned advises (using "bash","-c" parameters) but now I have stumbled into other issues:
My intention is to write a UNIX class, that can handle UNIX commands, in order to be used in other Java programs, so that the following example becomes possible:
UNIX.launch("cd /var/core");
UNIX.launch("rm obsolete_core_file");
UNIX.launch("sqlplus <Oracle_database>");
UNIX.launch("select * from cat;");Unfortunately I have stumbled into a strange behaviour: until now, I have created the UNIX class as a single class, containing a "main" method. When I launch the following commands:
java UNIX "cd /var/core";
java UNIX "rm obsolete_core_file"I have the problem that the "cd /var/core" command is executed while UNIX class is running, but afterwards I jump back to my current directory:
pwd => current directory
java UNIX "cd /var/core" (this is executed, e.g. verifying "ls" output)
pwd => current directoryI would like to have:
pwd => current directory
java UNIX "cd /var/core"
pwd => /var/coreOne other thing is the handling of sessions: until now, when I launch following commands:
UNIX.launch("sqlplus <Oracle_database>");
UNIX.launch("select * from cat;");Then I get into a "sqlplus" session, but afterwards my Telnet session hangs. Is there a way to see that I have fallen into a session, and handle it? (Exit, launch internal session (SQL-plus) command, ...)
Thanks again

How to run piped Unix commands

Hi,
I'm trying to run piped Unix commands using Runtime.getRuntime().exec(...) but apparently the pipe symbol ("|") doesn't seem to work...
Here is basically what I'm trying to do: running "command1 | command2" where both "command1" and "command2" have dynamic values. I could create a shell script and execute it through Java but there has to be a cleaner way...
Can anyone help me with this?
Thanks,
Thierry

The | symbol for a pipe is understood by a shell, so it was right to point to this direction.
If you still have a problem, that might be because of another reason. What did happen, how exactly� did it not work? Did you take care of the stdin and stdout channels of the launched process?

ARD: Unix commands wait forever

Hello,
I run a cluster of 30 iMacs. We've just updated them to Mountain Lion, and when trying to control them via ARD, all Unix commands (even hostname or echo a) show as "waiting" and never complete.
All machines involved are running Mountain Lion (or Mountain Lion Server in the case of the ARD master machine) and ARD 3.6.2.
Can you think of anything that might be causing this? Unix commands used to work instantly before the upgrade to Mountain Lion.
Thanks,
Louise

In addition to the sources Templeton mentioned, a good book on UNIX for Mac OS X (such as the O'Reilly books) would be useful. You can send through ARD many of the UNIX commands that Mac OS X recognizes, though of course you have to be careful what you send or you can cause yourself lots of problems.
