GOAL:
Why does Progress recommend turning OFF write back cache on the disk controller?
GOAL:
Should the disk controller be set to write back or write through in a Progress environment ?
FACT(s) (Environment):
All Supported Operating Systems
Progress/OpenEdge Product Family
FIX:
Progress database integrity relies on the fact that the .bi file is written as a guaranteed sequential write. If write back cache is enabled, it is possible that the bi notes will be written out of sequence.
