Enables the cache for HPFS386. Only valid for the OS/2 Warp Server Advanced otherwise CACHE386.EXE is started by the following command:

CALL=C:\OS2\CMD.EXE /Q /C C:\IBM386FS\CACHE386.EXE >NUL

Call to the cache program for HPFS386

options for CACHE386 (x is an optional drive letter):

/OPTIONS[:x] - Display current configuration
/STATS[:C|:D] - Display, clear, or dynamically display statistics
/LAZY[:x][:ON|:OFF] - Enable or disable lazy writing
/MAXAGE[:x]:n - Change msDataAge to n milliseconds
/BUFFERIDLE[:x]:n - Change msIdleBuf to n milliseconds
If no drive (x) is given, the option will apply to all HPFS drives.

Each option may be abbreviated to a single letter, for example:

CACHE386 /B:D:1000 (sets BufferIdle to 1000 for drive D)

ATTENTION: This entry has to be done manually. If this statement is not added you'll get the following error 'Net 3091: the Cache386.exe is not running. The server cannot be started.

Adding the parameter /STATS will display the statistic usage cache usage. This will help you to size the cache to a size where the minimum sized cache achieves the maximum hit rate.
