GOAL:
What is the Before-image File
FIX:
1) A file that ensures database integrity by keeping track of the status of your database in the event that a transaction is not completed or a system failure occurs. Unless you explicitly place this file somewhere else with the Before Image File Name (-g) startup parameter, the BI file is located in the same directory as your DB file. You can think of the before-image file as a pretransaction image of the database records your application is modifying. See also After-image File.
2) A file that is used to store a portion of the before-image log for a Progress database. When the before-image log is composed of multiple extents, these extents are sometimes collectively referred to as the before-image file
