What Is Database Writer Process?

1.	What Is Database Writer Process?
Answer» It writes the contents of buffers to DATA files.The DBWn processes are responsible for WRITING MODIFIED buffers in the database buffer cache to disk. However one database writer process (DBW0) is ENOUGH for most systems, you can configure other processes (DBW1 through DBW9 and DBWa through DBWj) to improve write performance if your system MANIPULATES data very much. These additional DBWn processes are not useful on uniprocessor systems. It writes the contents of buffers to data files.The DBWn processes are responsible for writing modified buffers in the database buffer cache to disk. However one database writer process (DBW0) is enough for most systems, you can configure other processes (DBW1 through DBW9 and DBWa through DBWj) to improve write performance if your system manipulates data very much. These additional DBWn processes are not useful on uniprocessor systems.
