JDBC and UCP Capabilities
Whether on the cloud or on-premises, developing Java applications with Oracle Autonomous Databases is fast and simple. Java developers can take advantage of the latest features, such as Oracle Autonomous Database, performance self-tuning, high availability, in-memory processing, and pluggable databases to design and develop a high performant, scalable, and reliable applications. Oracle Database 19c and 18c JDBC drivers introduce a new property file (ojdbc.properties) along with few other features that simplifies the connection to Autonomous Transaction Processing (ATP) and Autonomous Data Warehousing (ADW).
| Java Standards | Supports JDK15, JDK14, JDK13, JDK12, JDK11, JDK10, JDK9, JDK8 and compliant to JDBC 4.3 and JDBC 4.2 by JDBC driver (ojdbc11.jar (21c only), ojdbc10.jar (19c only) and ojdbc8.jar) and Universal Connection Pool (ucp.jar). JDBC Reactive Extensions - A set of methods that extend the JDBC standard to offer asynchronous database access. |
| Connection |
Easy Connect Plus for easier TCPS connections and passing connection properties (19c only); new ojdbc.properties file to set connection properties; multiple ways for setting TNS_ADMIN; setting server's domain name (DN) cert as a connection property; support of new wallet property (my_wallet_directory)
|
| Performance | Reactive Streams Ingest (RSI) for streaming data into the Oracle Database (21c only); Oracle connection manager (CMAN) in traffic director mode (CMAN-TDM) |
| Scalability | Java Data Source for Sharded Databases Access. Oracle RAC data affinity; shard routing APIs for mid-tiers; shared pool for multitenant and sharded database; and run time load balancing (RLB) |
| High Availability | Transparent Application Continuity (TAC); support of concrete classes with Application Continuity (AC); AC with DRCP; FAN support; and Transaction Guard (TG) |
| Security | Automatic Provider Resolution (OraclePKIProvider); support for Key Store Service (KSS); HTTPS proxy support; TLSv1.2 Support; Kerberos, Oracle Wallets, and JKS |
| Data Types | Support for New JSON Data Type. Accessibility to PL/SQL associative arrays; Oracle REF CURSOR as IN bind parameter; and JSON datatype validation |
