Frame data is received from an agent instrumented on a software component, the frame data describing a particular request from the software component to a database access component intercepted at the agent. The particular request corresponds to a transaction involving a database and the software component can interface with the database using the database access component. A service mode is identified that corresponds to the transaction and virtualization data is generated based on the service model and the particular request. The virtualization data is sent to the agent that describes a virtualized response to be provided by the agent to the software component as a response to the particular request.
