The PDB$SEED or SEED database is a pluggable database template for pluggable databases to be created by users. Used as a template to create new pluggable databases.
The PDB$SEED database’s container id is always 2. You can get information about PDB$SEED from v$pdbs. You need to be in the root container after connecting to the database. Otherwise, you cannot see the PDB$SEED database.
