Data Interpretation System 2.1.1 Service README
 
   This document provides instructions for applying and removing fix
   levels for Data Interpretation System (DIS) 2.1.1 Server and
   Workstation components.
 
   Fix levels for Intelligent Decision Server (IDS) are located at
   "ftp://ftp.software.ibm.com/ps/products/ids/fixes".
 
Overview
 
   Fix levels for DIS 2.1 1 Server and Workstation components are
   contained in self-extracting ZIP files.  All fix levels are
   cumulative; they contain every fix from previous levels as well as
   new ones.  You will need 10 megabytes of free hard disk space for
   each ZIP file and an additional 10-20 megabytes of free space for
   the extracted files.
 
   You must apply these fixes while DIS is running.  After you finish
   the application process, you will need to restart the DIS services
   for the fixes to take affect.
 
   Should you have any problems in applying a fix level please contact
   Technical Support, 1-800-959-4426.
 
Applying Fix Levels
 
   Each fix level is downloaded in a ZIP file that extracts itself
   into a set of files and directories that are used to upgrade your
   current system.  To apply an update:
 
      Download the desired ZIP files.  Each one should be downloaded
      into a separate directory.
 
      Extract the files in the ZIP file by typing its filename.  For
      example, type "do73kfix".  A new directory named "fix" is
      created in your current directory.
 
      If DIS services are not already running, click on the DIS icon
      on the OS/2 desktop.  Wait for the services to start completely.
 
      Type "cd fix" to change to the fix directory.
 
      In the OS/2 window, type "upgrade".  You might be prompted for
      the directory where the DIS software is installed on your
      workstation.  The fix application compares the timestamps of all
      files within its domain with files present on the Primary File
      Server.  Messages are displayed for each file, stating that your
      version is either newer than, or older than, or matches, the
      upgrade file.
 
      Type the system password when you are prompted to do so.  If you
      have not updated this password, type "original".  Messages are
      displayed informing you that the files are being replaced.
      NOTE: If you enter the wrong password, the upgrade will not occur
      and you will need to restart at the previous step, type "upgrade".
 
   After the new code is transferred, you must reset all workstations
   and services for the updates to take affect.  To do this:
 
      Log on to the DIS Desktop.
 
      Open the SA Tool.
 
      In the SA Tool, select "Network Command" from the "Service Type"
      menu.
 
      Click on the "Connect to Service" button.
 
      Type your password when prompted.  You are now in the "Network
      Commands" menu.
 
      Click on the "Reset All Workstations and Services" button.  The
      workstation you are using will reset and all services will
      recycle.  Monitor all network services to ensure that they
      reset.
 
   Also, ensure all temporary fixes have been removed, this pertains
   to any dlls that were added to the 'nodeovly' directory or using
   the /s parameter.  Please contact the Technical Support Engineer
   that supplied the temporary fix to verify that this needs to be
   done.
 
   DIS is now upgraded to the new fix level.
 
Undoing Fix Levels
 
   For each fix level, there is a corresponding undo level available
   in a self-extracting ZIP file.  For example, the undo level for
   "do73kfix.exe" is do73kund.exe.  When you apply a fix level undo,
   your system will return to the DIS 2.1.1 base level.  You can then
   apply any of the other available cumulative fix levels to move your
   system to the desired level.
 
   The steps for applying a level undo are the same as the steps for
   applying a fix level.  You will need 30 megabytes of free hard disk
   space to download and extract a level undo.
 
Available fix levels
 
   Each fix level and corresponding undo is located in a directory
   with the same name as the fix level.  Within each directory, the
   README.TXT file lists the problems that are fixed in that level.
