Hi
We are evaluating various RDBMS for use on within an airborne server
(Embedded NT4.0) environment.
This environment does not have reliable power. Aircraft are powered cycled
without regard for delicate OS environments etc.
We like MySql because it is fairly lightweight (regards processor/mem
requirements not capabilities) and fast. Availability of source code is also
re-assuring - given the long product lifecycles within the avionics
business.
Assume that we are not suffering from any file corruption due to problems
with NTFS under powerfail conditions.
Whether we use a table type which supports transactions or not has anyone
experienced problems under powerfail, and if they
have could it be automatically corrected within a reasonable time by the
table repair utilities. I am worried about internal indices (Btrees etc)
requiring a complete rebuild, and taking an unacceptable amount of time.
I plan to test before making any commitments but forwarned is forarmed as
they say.
Other DB's on the eval list are Interbase 6.0, MSQL7, various realtime
embedded.
Thanks & Regards
Norman Burkies
