Database role BECOME USER

List,

Does anyone has ever used the database role "BECOME USER"? If so, what are the possibilities for the user who has gotten the role?

This is my case:
In our Oracle databases we have several jobs (dbms_job) running in the Oracle queues. These are jobs "owned" by different users. I want to be able to change, delete and run jobs (of all users) through one Oracle database account. This is a "power" user.

Regards,
