Upgrading to Oracle Database 19c: Benefits and Considerations

Oracle Database 19c is the latest long-term support release of Oracle's flagship database management system. Upgrading to Oracle Database 19c offers numerous benefits, including enhanced performance, improved security, and advanced features. In this blog post, we will explore the benefits of upgrading to Oracle Database 19c and provide insights into the key considerations for a successful upgrade.

1. Performance Enhancements:

Oracle Database 19c introduces several performance enhancements that can significantly improve database operations. It incorporates optimizations for online transaction processing (OLTP) workloads, query execution, and in-memory operations. The Automatic Indexing feature automates index management, leading to better query performance. Enhanced Real Application Clusters (RAC) capabilities and Exadata optimizations further enhance scalability and performance, allowing businesses to handle increasing data workloads efficiently.

2. Advanced Security Features:

Security is a critical aspect of database management. Oracle Database 19c introduces advanced security features that strengthen data protection. These include Data Redaction, which enables sensitive data masking during query results, and Unified Audit, providing a consolidated audit trail for simplified compliance. Additionally, Oracle Advanced Security offers enhancements like Transport Layer Security (TLS) 1.2 support, secure configuration recommendations, and stronger authentication mechanisms, bolstering the overall security posture of the database.

3. Multitenant Architecture:

Oracle Database 19c builds on the Multitenant architecture introduced in earlier versions, allowing businesses to consolidate databases and achieve greater efficiency. Multitenant architecture enables the management of multiple pluggable databases (PDBs) within a single container database (CDB), reducing administrative overhead and resource utilization. The Container Database Resource Manager helps prioritize resources and manage workloads across PDBs, optimizing performance and resource allocation.

4. Application Development Improvements:

Oracle Database 19c brings advancements for application development and deployment. It includes support for new SQL capabilities, such as JSON enhancements, which facilitate easier data integration with web services and NoSQL databases. The Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW) services, powered by Oracle Database 19c, provide a self-driving, self-securing, and self-repairing database platform, freeing developers from tedious administrative tasks and enabling rapid application development.

5. Upgrade Considerations:

While upgrading to Oracle Database 19c offers numerous benefits, there are considerations to ensure a smooth transition:

a. Compatibility: Verify the compatibility of applications and tools with Oracle Database 19c to ensure seamless integration and functionality.

b. Pre-Upgrade Testing: Conduct thorough testing of the upgrade process in a non-production environment to identify and resolve any potential issues or conflicts.

c. Planning and Backup Strategy: Develop a comprehensive upgrade plan and ensure adequate backups of the existing database to minimize the risk of data loss during the upgrade process.

d. Performance Monitoring: Monitor the performance of the upgraded database and fine-tune configurations as needed to optimize performance in the new environment.

e. Patching and Maintenance: Stay up-to-date with Oracle's patching and maintenance recommendations to benefit from bug fixes, security updates, and performance enhancements.


Upgrading to Oracle Database 19c offers a range of benefits, including improved performance, advanced security features, enhanced application development capabilities, and streamlined database management. However, careful planning, compatibility assessment, and thorough testing are essential for a successful upgrade. By leveraging the new features and optimizations provided by Oracle Database 19c, businesses can unlock the full potential of their database infrastructure, drive innovation, and ensure a secure and efficient data management environment.
