DDR Simulation – Advanced Estimation & Runtime Analysis
DDR Simulation is one of the most advanced functionalities within Dynamic Data Replicator.
The Simulation feature allows organisations to accurately identify what the actual refresh execution
will look like before the live runtime execution begins.
The functionality provides complete visibility into estimated table reads, expected runtime duration,
workprocess usage, database sizing, package sizing, and workload distribution. This enables SAP teams
to perform controlled runtime estimation and execution forecasting before production execution.
DDR Simulation can also retain the simulation result in memory for later execution.
This significantly improves operational planning, runtime optimisation, execution preparation,
and large SAP refresh estimation activities.
Access the DDR Dashboard
From the DDR Central Console, select Dashboard from the left navigation menu. Select the export by clicking the radio button before the template name and then click Simulation from the execution toolbar.
Execute Simulation Runtime Analysis
When Simulation is executed, DDR performs an advanced estimation analysis to identify the expected runtime behaviour for the selected refresh template.
DDR will display a popup asking whether the simulation result should be retained in memory for later actual execution runtime processing.
- Yes: Retains the simulation result in memory for later runtime execution.
- No: Performs runtime estimation analysis only.
Key Benefits of DDR Simulation
DDR Simulation provides organisations with complete operational visibility before the actual runtime execution begins. This functionality is designed to reduce execution risk, improve runtime forecasting, optimise infrastructure usage, and provide accurate workload estimation across SAP refresh activities.
