Explanation/Reference:
A named credential is a users' authentication information on a system. A named credential can be a user
name/password, a public key-private key pair, or an X509v3 certificate. An Enterprise Manager
administrator can store these credentials as named entities in Enterprise Manager to use when performing
operations like running jobs, patching, and other system management tasks. For example, you can store
the user name and password that you want to use for patching as MyPatchingCreds. You can then later
submit a patching job that uses MyPatchingCreds to patch the production databases.
Named Credentials can be created for the credential types in Enterprise Manager 12c. The most
commonly used credential types for host and database target types are described in the following sections.
