PDBs
Oracle 12c introduced a new utility which replaces the need to run post installation SQL scripts after a database patch is applied.
This new utility is called “Datapatch” and it is shipped with 12c binaries as a component of OPatch distribution.
“Datapatch” is very useful in multitenant environments where multiple PDBs (Pluggable Databases) must be patched together.
