Return to The Config.sys Documentation Project Main Page

The Run statement in your config.sys file is used to run a program during boot up. Programs started by Run are executed in the background. The following pages describe these entries:

RUN=ACTVCOLL.EXE

Executable from Process Commander. The ACTVCOLL line gathers resource use information about sessions.

NOTE: By Mikus Grinbergs: For activity collection to work with FP12 systems and beyond, EXEPATCH must have been used to "hook" Process Commander into DOSCALL1.DLL.

Platform Support:

RUN=AEFSDMN.EXE

The AEFS daemon.

  The syntax is: aefsdmn *

It is typically started in CONFIG.SYS by a RUN statement (NOT a CALL statement) or from a script using the detach command.

You can change the options of a running daemon with aefsparm. The syntax is the same. The parameters given to aefsparm are sent verbatim to the daemon. Error messages appear in the log file (if there is one).

The options are:

--logfile Write log messages to the file specified by . By default, messages are written to standard error (which is the nul device if the daemon is started from CONFIG.SYS or using detach).

--loglevel Set the severity threshold of log messages. Only messages with a severity lower than or equal to the log level are actually written to the log file. The levels are:

1 Fatal
2 Evil (i.e. not fatal but worse than a `normal' error)
3 Error
4 Warning
9 Debug

--cache Set the maximum size of the cache per volume in 512-byte units. The default is 4096, or 2 megabytes per volume.

--storagefiles Set the maximum number of open storage files per volume. To speed up access to the encrypted files AEFS keeps the most recently used ones open. The default is 16. This number should not be made too high; otherwise the daemon might run into the open file limit of the C runtime library (use emxbind -a aefsdmn.exe -h to change this).

--files Set the maximum number of files for which AEFS may cache sectors. Every file in the cache has a slight overhead; hence the limit. The default is 4096 files.

--lastaccess=[active|lazy] Specify whether the last-accessed fields of files should be updated always (`active') or only if other fields have changed as well (`lazy'). The default is `active'.

--lazy=[on|off] Specify whether lazy-writing (or `write-behind') should be enabled. The default is `on'. If lazy-writing is enabled, AEFS will flush every volume every 5 seconds. This interval cannot currently be changed.

--quit Kill the daemon. Useful for debugging. Detach all attached volumes first.

--info Print statistics about the memory allocation of the daemon and about every attached volume. These appear in the log file.

NOTE: most options do not take effect for volumes that are already attached, only for volumes attached after aefsparm is run.

RUN=CACHE.EXE

This entry controls the behavior of the HPFS cache. It is normally not set in your config.sys. Set it only if you want to change the default settings. If you encounter any problems with this statement then delete it from your config.sys file and set it up in your startup.cmd file.

  RUN=C:\OS2\Cache.exe Parameters

Default settings:

LAZY: ON (use 1 thread)
BUFFERIDLE: 500 ms
MAXAGE: 5000 ms
DISKIDLE: 1000 ms
READAHEAD: ON

Parameters:

You can use the "/" or the "-" at the beginning of each parameter.

/LAZY:value

Value can be ON or OFF or in the range from 0 to 64 . Default = ON If this parameter is not set it defaults to 3 . The OS/2 online help says: "If this parameter is set no other parameters are allowed." This depends on your system, some user reported me that two lines gives errors at boot.

   o /LAZY:ON
   Lazy writing is on, three threads are used.

   o /LAZY:OFF
   Lazy writing is turned Off.

   o /LAZY:n
   n lazy write threads are used.

/DISKIDLE:value

Value can be in the range from 0 to 65535 . Default= 1000 The value is expressed in milliseconds. This is the amount of time that the disk is idle before data can be written from cache to disk.

/BUFFERIDLE:value

Value can be in the range from 0 to 65535 . Default= 500 The value is expressed in milliseconds. This is the amount of time that the cache-buffer can be idle before the cache data must be written to disk. The OS/2 Online help says that the BUFFERIDLE time must be smaller than the DISKIDLE time. I think this is wrong!

/MAXAGE:value

Value can be in the range from 0 to 65535 . Default= 5000 The value is expressed in milliseconds. This is the time data waits in the cache before the data is written to disk.

/READAHEAD:value

Value can be ON or OFF or 0 or 1 . This Parameter enables the read ahead buffer. Only from Warp 4.0

/DIRTYMAX:value

Value can be in the range from 0 to 65535 . The value is expressed in milliseconds.

/WRITECACHE:value

Value can be in the range from 0 to 65535 . The value is expressed in kilobytes.

See the examples below.

If you want to turn lazy writing off, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /LAZY:OFF

If you want to turn lazy writing on and set bufferidle to 4 seconds, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /BUFFERIDLE:4000

If you want to turn readahead off, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /READAHEAD:OFF

TIP: Lazy writes can also be turned ON or OFF at an OS/2 command prompt.

WARNING: If you include the /LAZY parameter, then the CACHE statement will IGNORE ALL OTHER PARAMETERS in the line. Therefore, if you want to turn lazy writes off (or on) and also change some other parameter, you will need two RUN statements.

WARNING: There is a bug in OS/2 version 2.1 which does not appear to have been fixed in Warp. You can't turn lazy writes off from the config.sys file. The WPS always turns lazy writes ON when it loads regardless of what your CACHE.EXE command sets. So, if you want lazy writes off, you will need to run the CACHE command AFTER the WPS starts. Create a CMD file to turn it off and place it in your Startup folder. The WPS has already done it's thing when the objects in the Startup folder are opened. You can also turn it off from a command prompt.

TIP: According to the OS/2 Guild running Voicetype in Warp 4.0 is speeded up with /READAHAED:ON According to one source at IBM, there are two other undocumented parameters. "Mr. HPFS" Doug Azzarito of IBM - Austin recommends them for testing only.

NOTE: Nearly everybody has his own recommendations about the correct size, so don't bother if you find different recommendations. Better try what is working best on YOUR system.

TIP: These settings can also easily done by using Warp'nGO or Xfolder Ver.080 and higher. Available at http://www2.rz.hu-berlin.de/~h0444vnd/os2.htm

NOTE: The HPFS.IFS config.sys file line sets up the cache and uses the system defaults. This config.sys file line is only used to modify the cache parameters.

TIP: You can check to see what parameters the HPFS cache is currently set at by going to an OS/2 command prompt and keying in the word CACHE and pressing the enter key.

NOTE: The full line of options must be on one line. If split into more than one line, the options split off will be ignored.

RUN=CACHE386.EXE

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.
