Puoi provare questo due modi di eseguire codice su Oracle DBMS.
Il primo è con codice Java: link
-- Usage example:
-- $ sqlplus "/ as sysdba"
-- [...]
-- SQL> @raptor_oraexec.sql
-- [...]
-- SQL> exec javawritefile('/tmp/mytest', '/bin/ls -l > /tmp/aaa');
-- SQL> exec javawritefile('/tmp/mytest', '/bin/ls -l / > /tmp/bbb');
-- SQL> exec dbms_java.set_output(2000);
-- SQL> set serveroutput on;
-- SQL> exec javareadfile('/tmp/mytest');
-- /bin/ls -l > /tmp/aaa
-- /bin/ls -l / >/tmp/bbb
-- SQL> exec javacmd('/bin/sh /tmp/mytest');
-- SQL> !sh
-- $ ls -rtl /tmp/
-- [...]
-- -rw-r--r-- 1 oracle system 45 Nov 22 12:20 mytest
-- -rw-r--r-- 1 oracle system 1645 Nov 22 12:20 aaa
-- -rw-r--r-- 1 oracle system 8267 Nov 22 12:20 bbb
-- [...]

create or replace and resolve java source named "oraexec" as
import java.lang.*;
import java.io.*;
public class oraexec
{
/*
* Command execution module
*/
public static void execCommand(String command) throws IOException
{
Runtime.getRuntime().exec(command);
}
/*
* File reading module
*/
public static void readFile(String filename) throws IOException
{
FileReader f = new FileReader(filename);
BufferedReader fr = new BufferedReader(f);
String text = fr.readLine();
while (text != null) {
System.out.println(text);
text = fr.readLine();
}
fr.close();
}
/*
* File writing module
*/
public static void writeFile(String filename, String line) throws IOException
{
FileWriter f = new FileWriter(filename, true); /* append */
BufferedWriter fw = new BufferedWriter(f);
fw.write(line);
fw.write("\n");
fw.close();
}
}
/
-- usage: exec javacmd('command');
create or replace procedure javacmd(p_command varchar2) as
language java
name 'oraexec.execCommand(java.lang.String)';
/
-- usage: exec dbms_java.set_output(2000);
-- set serveroutput on;
-- exec javareadfile('/path/to/file');
create or replace procedure javareadfile(p_filename in varchar2) as
language java
name 'oraexec.readFile(java.lang.String)';
/
-- usage: exec javawritefile('/path/to/file', 'line to append');
create or replace procedure javawritefile(p_filename in varchar2, p_line in varchar2) as
language java
name 'oraexec.writeFile(java.lang.String, java.lang.String)';
/
Il secondo sta usando ExtProc: link
-- Usage example:
-- $ echo $ORACLE_HOME
-- /opt/oracle/
-- $ sqlplus "/ as sysdba"
-- [...]
-- Connected to:
-- Oracle9i Enterprise Edition Release 9.2.0.1.0 - 64bit Production

-- JServer Release 9.2.0.1.0 - Production
-- SQL> @raptor_oraextproc.sql
-- [...]
-- exec oracmd32.exec('touch /tmp/32');
-- [...]
