Amazon Relational Database Service (RDS) for Oracle now supports converting existing Oracle Database 19c instances from the non-multitenant to the multitenant database architecture in the Amazon Web Services China (Ningxia) Region, operated by NWCD, and the Amazon Web Services China (Beijing) Region, operated by Sinnet. DB instances using the multitenant architecture consist of a container database (CDB) with a single pluggable database (PDB). A PDB is a set of schemas, schema objects, and non-schema objects that logically appears to a client as a non-CDB.
Starting today, Amazon RDS for Oracle customers can convert existing 19c non-CDB instances to CDBs. Starting with Oracle Database 21c, the non-CDB architecture is desupported by Oracle, and you must upgrade your non-CDB Oracle Database to a multitenant database (PDB on a CDB). Please note this conversion is a pre-requisite, if you are planning to upgrade from Oracle Database 19c to 21c. Amazon RDS for Oracle supports the multitenant container database for versions 19c (starting from the Release Update 220.127.116.11.ru-2021-04.rur-2021-04.r1) and 21c for customers who use any edition of Oracle Database with the License Included or Bring Your Own License models.
Amazon RDS makes it easy to set up, operate, and scale a relational database on Amazon Web Services Cloud.
