Hi all,
I use DBMS_SCHEDULER to execute one SH program,
When i excecute my Procedure PL I have this error message :

ORA-27369: job of type EXECUTABLE failed with exit code: Operation not permitted STANDARD_ERROR="XY7_LOG: Permission denied"


My procedure is :

CREATE OR REPLACE PROCEDURE PROC_GET_WEB_PAGE

p_rep VARCHAR2(400);
p_url VARCHAR2(400);
p_cookies param_get_file_converter.url_cookies%TYPE;
p_name_cookies param_get_file_converter.cookie_name%TYPE;
p_name_file_log param_get_file_converter.name_file_log%TYPE;
p_nom_fichier param_get_file_converter.file_name_converter%TYPE;
p_user_site param_get_file_converter.user_converter%TYPE;
p_pwd param_get_file_converter.pwd_converter%TYPE;

dbms_output.put_line('p_name_file_log'||p_name_file_log);

dbms_scheduler.set_job_argument_value('testjob3',6,p_rep||p_nom_fichier);
dbms_scheduler.set_job_argument_value('testjob3',7,p_url);
dbms_scheduler.enable('testjob3');
dbms_scheduler.run_job('testjob3');

EXCEPTION
