Database Replay

Overview

System changes such as hardware/software upgrades, patch application, etc. are essential for businesses to maintain a competitive edge for compliance/security purposes. Businesses spend significant time and effort evaluating and testing system changes in test environments before introducing them in production systems. However, despite such testing, using various scripts and simulation tools, many issues often go undetected until production deployment and negatively impact system performance and availability. The main reason for low success rate of testing is the inability of existing tools to test using real production workloads. Database Replay, one of the solutions within the Oracle Real Application Testing option enables realistic testing of system changes by recreating the production workload on the test system while maintaining the unique characteristics of the workload.
