One of Oracle12’s key new features is the container database, also called the plugable database, or CDB’s…container database.
New name and name on price list: Multitenent DB.
Lets look at the ‘c’ in Oracle12c.
The root database contains the metadata, common users, common resources for the and is called the CDB or the ‘container database’. The PDB’s are the application DB’s…just like non-container DB’s (the current setup with Oracle11g and prior DB’s). The Seed database is used for a template for any new PDBs to be added to this container DB.
When planning to go to this new environment:
Oracle12 release 2…this will be the default installation option. I will blog some other useful tips in the future on CDB/PDB’s but for now, this is Oracle’s direction with their database product.
This architecture should aid the DBA staff the most:
This is Oracle’s direction for platform, cloud, and database management. Embrace it, don’t fear it…the multitenent DB is your friend. This new environment shouldn’t be very different for the developer and it should greatly simplify some of the current tedious tasks performed and administered by the DBA.
