Problem: Slowdown in SAS data set performance

Prerequisite Software: DIS 8.2

To install the patch [UNIX]:

1. Change directory to the root directory of the dfPower/DIS installation. 
   This is the directory named 'dfpower' created during installation. For 
   example, if you installed DIS in /opt/dataflux, run this command: 
 
       cd /opt/dataflux/dfpower

2. From that directory, run this command:
   
       gzip -d -c PATH_TO/dis-fix12991-PLATFORM.tar.gz | tar xvf -

   replacing PATH_TO with the correct path to the patch file and PLATFORM with
   the the platform name (linux, sol64, etc.).

To install the patch [Windows]:

1. Unzip the archive dis-fix12991-win32.zip into the root directory of your
   dfPower/DIS installation. This is typically:

      C:\Program Files\DataFlux\dfPower Studio\8.2
 
   or:

      C:\Program Files\DataFlux\DIS\8.2

   Substitute the appropriate directory if you installed the product in a
   different location.
