Issues with CDB User Creation and tablespace allocation in Oracle 12c Database In Oracle12c, the concept of database plug-in is added, that is, PDB, which allows a database container (CDB) to host multiple pluggable databases (PDB ). CDB is called ContainerDatabase, and the Chinese translation is a database container. PDB is called PluggableDatabase, which can be
