True. But that job is going to run in a separate session, some time after the current transaction commits (depending on the number of jobs queued up to run). So if you need to pass information back from the job, or you want the procedure to handle exceptions thrown by the job, or you want to tie job related failures back to a particular application level event, or you want the rest of your procedure to wait for the operating system command to finish, using the DBMS_SCHEDULER for this sort of thing is going to require a fair amount of additional coordination/ monitoring/ infrastructure code. It's certainly not a Herculean task to write that additional code, and it's reasonable in some situations, but the Java stored procedure approach strikes me as substantially easier to deal with in most cases.
