Background writers
The OpenEdge Enterprise RDBMS offers three background writer processes that improve performance. These processes continually perform certain housekeeping functions in the background. Because these functions are performed regularly by the dedicated background writer processes, client and server processes rarely have to wait for these functions to be performed.
The three types of background writers, asynchronous page writers, before-image writers, and after-image writers, are described in Processes on Windows and UNIX platforms and in the Processes on UNIX platforms. The AdminService starts the background writers if the AdminService has been configured to do this by OpenEdge Management or OpenEdge Explorer. For more information about background writers, see OpenEdge Data Management: Database Administration.
