Oracle 19c, the latest release from Oracle, offers several features that enhance performance, security, and manageability for businesses. One of its key advantages is automatic indexing, which uses machine learning to optimize query performance without manual intervention. Additionally, it allows up to three pluggable databases (PDBs) in a single container database (CDB), improving resource utilization and simplifying management. Oracle 19c also enables high availability by allowing DML operations on standby databases.
