allocated to store (cache) database pages in memory to help improve the efficiency of the database performance. It is far quicker to read data from memory that it is to have to physically read the data Database Write Mode Many operating systems employ a disk cache mechanism. This uses an area of memory (which may be part of your server’s overall RAM or may be built into the disk hardware) to buffer operating system to write the data when it gets around to it. To give the DBA or database owner full control of when data is written, the gfix -w[rite] command can be used. The command takes two parameters:
