Kim Haase updated DERBY-5691:
-----------------------------
Attachment: DERBY-5691-2.zip
DERBY-5691-2.stat
DERBY-5691-2.diff
Thank you, Kathey, for the great comments!
I'm attaching a second patch, DERBY-5691-2.diff, DERBY-5691-2.stat, and
DERBY-5691-2.zip, with the following changes:
M src/adminguide/cadminpreface23947.dita
M src/adminguide/derbyadmin.ditamap
A src/adminguide/cadmindbintegrity.dita
M src/devguide/cdevdgpref11181.dita
M src/devguide/cdevdvlp14839.dita
I added the information you suggested to two topics in the Developer's Guide:
one in the "Purpose of this guide" topic in the preface and, since people don't
always read the preface, in the "Application development overview" topic where
the book starts to get into substantive areas. The language may need some
changes, though.
I hope the changes to the new Admin Guide topic are satisfactory. I am most
uncertain about the fix to the runtime compression item.
Please let me know if further tweaks are needed.

> 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.
