Call to the cache program for HPFS386.
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
Parameters
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.
