The database writer process (DBWn) writes the contents of buffers to datafiles. The DBWn processes are responsible for writing modified (dirty) buffers in the database buffer cache to disk. Although one database writer process (DBW0) is adequate for most systems, you can configure additional ...

In general, it is better to be connected through adispatcherand use a shared server process. This is illustrated inFigure 4-2, "Oracle Database Shared Server Processes". A shared server process can be more efficient because it keeps the number of processes required for the running instance lo...

通过DB_WRITER_PROCESS参数可以控制DBWn进程的数量。 4.LGWR LGWR,或称为“日志写入程序”进程,负责管理重做日志缓冲区。在具有大量DML活动的实例中,LGWR是最活跃的进程之一。直到LGWR成功地将重做信息(包括提交记录)写入重做日志文件,才能认为事务已经完成。此外,直到LGWR已经写入重做信息,才可以通过DBWn将缓冲区缓存中...

With Oracle Database, the database writer process writes data buffers modified in memory to the data files of the database, using a least recently used (LRU) algorithm. The database writer process manages the buffer cache so that user processes that must read blocks from disk into the ...
