Once you have your RMAN stuff figured out, let us know, and we'll show you how to call it from a DBMS_SCHEDULER job you can define from SQL Developer.
We have RMAN integration as well, but it also assumes your proficiency with the subject.
But i don't have idea about setting the RMAN. Can please guide me to configure RMAN setting.
The forums aren't the place to learn about Oracle backup and recovery strategies and technologies. I recommend starting with the Docs.
Ok Jeff...Thanks. I will try with docs.
