-------------------------------------------------
Key: DERBY-5691
URL: https://issues.apache.org/jira/browse/DERBY-5691
Project: Derby
Issue Type: Improvement
Components: Documentation
Environment: Microsoft Windows
Reporter: Stan Bradbury
Suggestion that we document a recommendation that Windows Write Caching be
disabled on machines using Derby.
The following article warns about Write Caching on Windows as a possbile source
of database corruption:
http://support.microsoft.com/kb/281672
It is possible that this could be the cause of some unexplained Derby
corruptions identified after power failure of other system interupt.
Links explaining how to disable Write Caching:
Win 2K: http://support.microsoft.com/kb/259716
Win 2008: http://support.microsoft.com/kb/324805
>From the Windows 2008 article:
With some third-party programs, disk write caching has to be turned on or off.
Additionally, turning disk write caching on may increase operating system
performance; however, it may also result in the loss of information if a power
failure, equipment failure, or software failure occurs. This article describes
how to turn disk write caching on or off.
