Techniques are described herein for effectively managing usage of a shared object cache in a container database management system (DBMS). The shared object cache maintains shared objects belonging to a set of pluggable databases (PDBs) hosted by the container DBMS. In an embodiment, a shared object metadata extension structure (SOMEX) is maintained for each PDB. The SOMEX stores metadata for each shared object of the PDB that resides in the shared object cache. In an embodiment, a share of the shared object cache is maintained for shared objects from each PDB in the set of PDBs based on entries in the SOMEX for the PDB.
