risk of data loss

Hello all,

I have to investigate under what circumstances a data loss in Linux might
occur (e.g. server crash when data is in filesystem cache only). Data loss
is possible if the application has got "I/O complete" although the data to
be written is not yet "on disk". The handling within the storage
(subsystem) is not in scope.

In addition I shall find out if there are special technologies used by
some common Linux applications (Oracle, MySQL) to circumvent this problem
(e.g. Oracle with raw devices). Maybe there are certain options that
minimize the risk of data loss (kernel options, special filesystems or
filesystem options).

Can someone give me some advices or point me to some useful sites in the
web, please? Any help is appreciated - thanx in advance.

Mit freundlichen Grüßen / Best Regards
Oliver Fenker
