In this video, we will explain about the Oracle Database Writer and describe its function as the background process responsible for writing data blocks from memory to disk
- [Narrator] So far, we've talked about the SGA…and PGA parts of the Oracle instance.…The SGA and PGA are areas in memory used…for caching various types of database data…as well as database metadata.…In addition to caching, the Oracle Instance…also contain what are know to be…the Oracle background processes.…These are a bunch of dedicated server-side processes…running in the background.…And similarly to the way that different components…of the SGA cache different types of data,…similarly, different Oracle background processes…have different functions.…
Functions such as writing database blocks to disk,…writing redo entries to disk,…making sure all of the database files…on disk are synchronized, and others.…The background processes perform maintenance tasks…required to operate the database…and maximize performance for multiple users.…This is why each background process…handles a different task.…So, are you ready to get to know this background processes?…If so, let's dive right in. Take it all in.…
