"fast" and "failure-proof" are to a certain extent mutually exclusive. If you want to be absolutely sre about your logging, than the log record has to be written as part of the same transaction in which the event being logged is executed. The ACID semantics of transactions ensure that the log and the action are either atomically executed, or not at all.
Practically this is most easily achieved using databases. Since this is not acceptable to you, my advise would be to develop you own Log4J appender that logs a message to two files (on two different disks) and flushes after every write... ++Jos.es And thus it came to pass that costin wrote: (on Mon, Mar 24, 2003 at 11:54:49AM +0200 to be exact) > Hi! > > I`ve approached this subject before on the list but I haven`t found > any satisfactory responses. > > I have an application where logging is a HUGE priority.
