SCO OpenServer Release 6.0.0 

          Even though I have configured my system for large files, I 
          still get the "value too large for defined data type" error when 
          dealing with files larger than 2 Gig.

          Only certain commands have been enhanced to deal with 
          large files.  To be certain that you are using the large 
          file aware versions of these commands, be sure that your 
          PATH is preceded by /u95/bin.  

          Also be certain that your ulimit for file creation is set
          to unlimited.
           
          To see if this is the problem, you could try a test like 
          this: 
           
     PATH=/u95/bin:$PATH;export PATH 
     ulimit -f unlimted
     (then retest the same commands) 
           
          To make this change more permanent, be sure that /u95/bin 
          is listed first everywhere the PATH might be set.  Most 
          likely, the users' $HOME/.profile files, but possibly also 
          in /etc/profile or in the startup scripts for your 
          applications. Also set the `ulimit` in these same scripts.
             
          To make the change for all new users the profile files in  
     /usr/lib/mkuser/*/profile could be updated.

          Update the file /usr/lib/cron/.proto to set the PATH and 
          ulimit for cron jobs.
