Sending down Linux commands from database

Question

Hello
Im working with Oracle 10.2.0.4.3 on Linux SuSE FUSE Version 2.3.0-RC0-SL0/SLES-9.
Im currently doing an extract of BLOB files down to a directory on the server.
When I do the extract the Oracle user becomes the owner of the files and my own user doesn't have the access (neither read or write) to the files.
I cannot receive Oracle access due a security issue so Im wondering if its possible to send down a command from the database that does a
$chmod a+rw my_directory/*.* ?
Iv looked into the some forums and I didnt find anything in particulate that would help me, so Im wondering if any of you know if this is possible ?

Hello
Thank you for your advice but the question was to send down Linux commands from the DB, not do anything in the Linux enviroment.
Here is a good place to start that I found on the net.
public class JShellCommand {
public static int execute(String cmd) {
try
String[] shellCmd = { "/bin/sh", "-c", cmd };
Process process = Runtime.getRuntime().exec(shellCmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
load it into db with loadjava and wrap it with:
CREATE OR REPLACE
FUNCTION Shell_Command(
p_CMD IN VARCHAR2
RETURN NUMBER
AS
LANGUAGE JAVA
NAME 'JShellCommand.execute(java.lang.String) return int';
For OS command you can use:
public class JCommand {
public static int execute(String cmd) {
try
Process process = Runtime.getRuntime().exec(cmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
and
CREATE OR REPLACE
FUNCTION OS_Command(
p_Cmd IN VARCHAR2
RETURN NUMBER
AS LANGUAGE JAVA
NAME 'JCommand.execute(java.lang.String) return int';
