Exploring the Features of Oracle Autonomous Database

Oracle Autonomous Database offers a range of advanced features designed to simplify database management and enhance performance. Here’s an overview of what makes this technology stand out:

• Automated Index Management: The system automates key index management tasks such as creating, rebuilding, and dropping indexes, adapting dynamically to changes in application workloads.

• Dynamic Resource Allocation: As your workload or storage demands grow, Oracle Autonomous Database can automatically scale CPU, I/O resources, and additional storage to meet these needs efficiently.

• Frequent Statistics Gathering: By default, the database gathers real-time statistics every 15 minutes, ensuring that performance optimization is based on the most current data.

• Real-Time Statistics Collection: While conventional DML workloads are running, Oracle Autonomous Database collects real-time statistics to keep performance finely tuned.

• SQL Plan Management: The system automatically assesses and identifies opportunities for SQL plan changes, optimizing performance for frequently executed SQL statements.

• Resource Quarantine for SQL Statements: To manage resource consumption, Oracle Autonomous Database can quarantine execution plans of SQL statements that excessively use system resources, ensuring balanced performance.

• Automatic Partitioning: The database analyzes and automates the creation of partitions for tables and indexes, improving both performance and manageability.

• Support for Complex Data Types: It supports complex types in ORC, Avro, and Parquet structured files, enhancing the flexibility of data handling and querying.

• Apache ORC Format Support: For seamless data loading and querying, the database supports the Apache ORC format, making it easier to work with data in object storage.

• Preinstalled RMAN Recovery Catalog: The Recovery Manager (RMAN) recovery catalog is preinstalled in the schema RMAN$CATALOG, based on the latest Oracle Database version, streamlining backup and recovery operations.

• Automatic Initialization Parameter Configuration: When provisioning a new database, Oracle Autonomous Database automatically configures initialization parameters. You can still modify these parameters if necessary.

• Autonomous Data Guard: This feature provides a standby (peer) database to ensure data protection and disaster recovery, enhancing the reliability of your Autonomous Database instance.

Oracle Autonomous Database’s automation and intelligent management capabilities redefine database efficiency, making it a powerful choice for modern data solutions.
