SAP HANA Capture and Replay

The crutial part of platform lifecycle is maintaining system stability during:

  • hardware changes
  • software changes
  • configuration changes

System admins are required to run a thorough simulation and testing prior to every upgrade of a productive IT system to not jeopardize live IT operations.

The integral part of SAP HANA SPS12, released on 11 May 2016, is the first version of SAP HANA capture and replay, a capability of the new SAP HANA performance management tools kit.

With SAP HANA capture and replay, you can simulate and analyze a complete system upgrade cycle using your own productive data, which ensures high precision when it comes to performance and cost KPIs.

A typical cycle:

  • Capturing the workload in the productive system for a defined time slot, including all incoming SQL statements and copying this data into the test system.
  • The required changes, like software upgrades, hardware changes or modifications to the configuration are applied in the testing environment.
  • The workload is replayed in the testing environment.
  • Finally, in the analysis phase runtimes between capture and replay can be compared to identify issues and hot spots and to plan optimization and tuning measures.

These phases can be iterated until the desired performance KPIs are reached.
