ADMINISTERING
Disables the database cache when you need exclusive access to a file in it.
Details
By default, the database cache is enabled on a server. Use this command to disable the database cache when you need exclusive access to a file that might be in the database cache. For example, to run an application such as a virus checker or backup software, disable the cache.
CAUTION: Whenever possible, avoid disabling the database cache. Doing so leads to increased I/O activity and a corresponding drop in server performance. When you must disable it, re-enable it as soon as possible.
To re-enable the dbcache, restart the server.
