• Support for Longer Passwords

  Starting with this release, Oracle Database supports passwords up to 1024 bytes in length. In previous releases, the Oracle Database password length was up to 30 bytes. The increased maximum password length provides the following benefits:

  • It accommodates passwords that are used by Oracle Identity Cloud Service (IDCS) and Identity Access Management (IAM). The increase to 1024 bytes enables uniform password rules for all Cloud deployments.
  • The 30-byte limitation was too restrictive when password multi-byte characters used more than 1 byte in an NLS configuration.

  The Oracle Database 23ai JDBC drivers support this increase in the password length.

• Starting from Oracle Database Release 23ai, connection pooling support is implicitly provided to JDBC applications that do not use connection pools. So, even if your application does not close a connection explicitly, Database Resident Connection Pool (DRCP) servers are automatically assigned to and from an application connection at run time, when the application initiates and completes database operations.
