• Load test database infrastructure changes

• Capture complete production application workloads

• Replay in test environments

• Reduce testing time and effort

Replay

Workload

Database Replay

• Database load and performance testing with real production workloads

• Workload characteristics such as; timing, transaction dependency, think time

• Test and measure transaction throughput for improvements

• Identify application scalability and concurrency problems on new Exadata hardware

• Remediate issues pre-production for risk-free migration

• Supports migrations from Oracle Data base 9i R2 and Oracle Database10g R2

Captured

Workload Replay

Workload Compare Performance

• SQL unit testing for response time

• Test and measure Exadata impact on response time for real, production SQL statements

• Identify all plan changes and/or regressions

• Eliminate SQL regressions with SQL Tuning Advisor and SQL Plan Baselines

• SPA Exadata simulation helps estimate I/O savings for the specific application workloads

without provisioning Exadata hardware
