Calling batch file using dbms_scheduler

Question

Hello,
i have created a schedule, program and a Job to using the DBMS_SCHEDULER. creates all those fine but when i try to run i get errors.
here is the code:
begin
dbms_scheduler.create_schedule(
schedule_name => 'dailyjob',
repeat_interval => 'FREQ=DAILY; INTERVAL=1;
BYDAY=TUE; BYHOUR=4',
comments => 'schedule to run daily');
dbms_scheduler.create_program
( program_name => 'runord',
program_type => 'EXECUTABLE',
program_action => 'd:\oracle\product\admin\scripts\ord.bat >nul',
enabled => TRUE,
comments => 'ORDERS.'
dbms_scheduler.create_job (
job_name=>'TEST',
program_name =>'runord',
schedule_name=> 'DAILYjob',
enabled => true,
comments => 'TESTING the Orders Job.'
end;
exec dbms_scherduler.run_job('TEST');
gives me the errors.
in the batch file i am calling connecting to the database and calling the sql file. is there any way that i can connect to the database directly from scheduler itself? i dont like to save username and passwords in a file to connect and invoke sqlplus?
could any one help.....

Answer 1

Pass them to the external command line as parameters? That exposes the name and password even more.
We use a tightly controlled directory with this information in it and access to the directory is controlled. The scripts are also in a controlled directory and have read privileges where the credentials are stored.
That way the scripts don't have the data exposed and don't use it until they run.
