Can I have a job in the library retrieve a password from a stored credential in Enterprise Manager?

Hi.

I'm wondering if this is possible and if so, how do I do it?

I'd like to have a job in the library that runs a shell script that is stored on the server.  As an example, let's say the shell script runs autoconfig for an E-Business Suite instance, and when autoconfig is run you need to enter the apps password, which is just a database account.

I'd like to store that apps password in Enterprise Manager and either have the shell script retrieve the password or have it passed as a parameter.

Is this possible?
