Instructs the FairCom Server to open its transaction logs in synchronous write mode. In this mode, writes to the transaction logs go directly to disk (or disk cache), avoiding the file system cache, so the server is able to avoid the overhead of first writing to the file system cache and then flushing the file system. As of FairCom DB Version 9, this is applicable to both Windows and Unix Systems.

Note: On the Solaris operating systems, COMPATIBILITY LOG_WRITETHRU uses the O_DSYNC mode to implement synchronous log writes when available. (Direct I/O with O_SYNC is still used on those systems not supporting O_DSYNC.)

Default: OFF
