Join David Yahalom for an in-depth discussion in this video Local vs. common user concepts, part of Oracle Database 12c: Security.
- [Instructor] Oracle 12c introduces…a new multi-tenant database architecture…where multiple PDBs or Pluggable Databases…share the same Oracle instance.…With this new architecture change,…Oracle also introduces two distinct types of database users.…These are common users and local users.…The difference between common and local users…is pretty straightforward, but nonetheless important.…A local user account is the user account…that was created inside a PDB.…
It is local to a unique PDB.…For example, if we created a my_user database user in PDB1,…then that user will exist in the scope of PDB1 only.…We can also create another user with the same name…but in another PDB such as in PDB number two.…Now, we have two users with the same name,…but each is local to its own PDB.…
Each user will have privileges on objects inside the PDB…in which the user was created.…On the other hand,…common users in Oracle are special users…that are created inside the root container…using a special naming convention.…They need to start with the C## prefix…
Learn how to identify the major risks and security threats, and review general best practices for properly protecting and "hardening" any production database. Then, dive into hands-on demos that show how to set up user accounts, the connection between users and schemas, database object and system permissions, and roles in a multitenant environment, as well as encrypt data, audit user actions, and access to sensitive information. Plus, find out how to enable data-at-rest security via the Oracle Transparent Data Encryption and backup encryption options.
