   readme.txt for vt4fixes
   ---------------------

   This archive includes the fixes for VoiceType Dictation/Navigation
   originally included with OS/2 Warp Version 4. These fixes are not
   included in the archive \TVoice\Wiseprog\VoiceType.zip located on
   the 'eComStation Preview Add-on CD'.
   The files have been extracted from the OS/2 Warp 4 base operating
   system FixPak XR_M015. Just copy them over the installed ones.

   Furthermore two files for use with the Journaled File System feature,
   two new RAS utilities and the description for the new RexxUtil
   functions are included. These files are not included in the
   eComStation resp. the Rexx documenatation has not been updated.
   I took the original readrexx.txt file, modified the entries to fit
   the look of the 'Object Rexx Reference' and compiled it for usage
   with the Information Presentation Facility (IPF). After copying
   READREXX.INF to \OS2\BOOKS, open the object preferences for
   'Assistance Center' -> 'Information' -> 'Reference and Commands'
   -> 'Rexx Information', on the 'Program' page edit the 'Parameters'
   entry field by adding '+READREXX.INF' behind 'REXX.INF'. Now when
   you start 'Rexx Information' the contents of READREXX.INF is appended
   at the end.

   The files have been extracted from the OS/2 Warp Server for
   e-business base operating FixPak XR_E002.

   January 18, 2001 - Warp Server for e-business FixPak XR_E002

   Excerpt from the readme file:
   (ftp://service.boulder.ibm.com/ps/products/
    os2/fixes/v4.5warp/english-us/xr_e002/readme.1st)

   7.1 NEW RAS UTILITIES ADDED

   Two new RAS utilities are included for Pak 01: PSFILES.EXE and
   PSSEMS.EXE.

   PSFILES.EXE can dump out information about open files on the system.  By
   default, it dumps out the information for all processes. Alternately,
   "PSFILES xxx" will dump out information for PID xxx (xxx is a hex number,
   e.g. from PSTAT).

   PSSEMS.EXE can dump out information about open 32 bit semaphores on the
   system By default it prints out all the shared (i.e. system-wide)
   semaphores.  Usage is:  pssems [/n] [hex_pid | /a] ; where /n suppresses
   shared semaphores and /a prints pruivate sems for all system processes.

   Note: These RAS Utilities are added to the OS2 directory on your system.


   7.2 JFS LAZYWRITE PARAMETERS ON THE IFS= LINE IN CONFIG.SYS

       IFS=jfs.ifs /L:OFF
       IFS=jfs.ifs /L:synctime,maxage,bufferidle


   (JFS ignores any characters between the L (or l) and the colon, so valid
   flags are /L: /LAZY: /LW: /lazywrite: etc.)

   OFF forces asynchonous writes to be immediately initiated.

   synctime is the interval at which the sync thread runs. Default = 64

   maxage is the longest time that a frequently modified file is kept in
   cache
           default = synctime*4

   bufferidle is the time indicating a "recent" change.  Changes newer than
           this value are not written unless the last write was older than
           maxage.  default = MIN(1,synctime/8)

   (All parameters in seconds)

        IFS=C:\OS2\JFS.IFS /L:64

        synctime = 32, maxage = 128, bufferidle = 4

        IFS=C:\OS2\JFS.IFS /LW:10,60,5

        synctime = 10, maxage = 60, bufferidle = 5

        IFS=C:\OS2\JFS.IFS /LAZYWRITE:4,60

        synctime = 4, maxage = 60, bufferidle = 1

        IFS=C:\OS2\JFS.IFS /lazy:off

        All writes initiated immediately (synctime=1, maxage=bufferidle=0)
        Note: sync thread still runs since trivial things like marking an
        inode accessed are still deferred.


   The cachejfs.exe command allows the lazywrite parameters to be changed
   immediately.  The syntax is to the IFS line, except that the /L: prefix
   is optional.  In addition, the cachejfs command can modify the minimum
   and maximum number of free cache buffers to be maintained.  Calling
   cachejfs with no parameters reports the current settings.

   CACHEJFS [[/LAZYWRITE:]{OFF|syncTime[,maxAge[,bufferIdle]]}]
   /MINFREE:minfree
            /MAXFREE:maxfree

   Additional information for CHKLGJFS.EXE:

   This is a command line tool used to format and view the
   CHKDSK/JFSCHK32 log entries.

   Usage: chklgjfs [-L[:N|:P]] Device

        chklgjfs D:
        chklgjfs -L D:
        chklgjfs -L:N D:

   displays most recent (default) chkdsk service log for JFS formatted
   drive D

        chklgjfs -L:N D:

   displays previous chkdsk service log for JFS formatted drive D
