CDB operations

CDB (Container Database) operations involve managing a central database that hosts multiple separate, isolated databases called pluggable databases (PDBs). Think of the CDB as a master container that controls resources, security, and administration for all its PDBs. Operations include creating new PDBs, opening or closing them for use, unplugging (removing) PDBs, and plugging in (adding) new ones. These activities allow efficient management, scalability, and resource sharing within the Oracle multitenant architecture, enabling organizations to run multiple databases within a single, consolidated environment while maintaining isolation and security for each PDB.
