Using the delta books utility program

After you gather the DLA books and load them to TADDM, you can use the delta books utility program to generate the delta books.

1. To use the delta books utility program, extract the following archives:
   • For UNIX:

     $COLLATION_HOME/tools/deltabooks/deltabooks.tar

   • For Windows:

     $COLLATION_HOME/tools/deltabooks/deltabooks.zip

2. Run the deltabooks.sh script or the deltabooks.bat batch file with the following syntax:

   deltabooks.sh|bat -f <fully qualified path to directory that contains first discovery output> 
   -t <fully qualified path to directory that contains the second discovery output> 
   -o <fully qualified path to directory for the delta books> [-verbose] [-allowReversedOrder]

   where:
   • The -verbose parameter enables verbose output.
   • The -allowReversedOrder parameter allows to reverse the order of books comparison so that the books from the first discovery are newer than the corresponding books from the second discovery.
     Note: This parameter is available in TADDM 7.3.0.2 and later.
   Example: deltabooks.sh -f /first_output/ -t /second_output/ -o /delta_books/
3. Review the delta book output to make certain that all book-pairs were processed. Especially look for lines that contain the following messages:
   • Failed to generate delta book
   • Failed to generate delta books
