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.
