SQL Watch is a new capability in Database Management cloud service that enables automated and accurate change impact assessment of system changes such as database upgrades, patch sets, migrations, minor application upgrades, add/drop index or routine refresh of optimizer statistics.

• SQL Watch is designed to predict and prevent SQL execution performance issues caused by above such changes.
• By running SQL statements before and after the change with real production context, it generates a comprehensive report that outlines the net impact on the workload resulting from the change and identifies any regressed SQL statements.
• For these regressed SQL statements, SQL Watch offers detailed execution plan insights as well as proactive recommendations to remediate them.
