Setting FILE_TRACE_FLUSH to 1 (on) causes AcuServer to flush the error trace buffer to disk after every WRITE operation. This ensures that in the event that the acuserve daemon terminates abnormally, all file trace information, up to the last WRITE operation, is captured in the log file. If this configuration variable is not used (set to 0 or off) and AcuServer aborts unexpectedly, an undefined amount of file trace information will be lost. FILE_TRACE_FLUSH is set to 0 by default. Note that you can also enable file trace flushing when you start the acuserve daemon by including the -t 5, -t 6, or -t 7 command-line switch in the -start command or by setting FILE_TRACE to 5, 6, or 7 in the server configuration file. See Starting and Stopping acuserve for more information.
