Presentation Title

Profiling the Logwriter and Databasewriter


Most of the time, the foreground or shadow process is traced to understand what the composition of the responsetime is. However, when doing (batch) DML, both the logwriter and databasewriter are key processes for the overall response time.

To gain an understanding of these processes, tracing gives an insight into what they are doing. The goal of this presentation to show the common events for these processes, including a detailed explanation of what these mean, and how the interaction with the operating system works.
