FIX checksum validation

About this task

The IBM Sterling Transformation Extender Pack for Financial Payments ships with FIX checksum utility maps. The fxchksm2_validate utility map is used to verify the computed FIX checksum value against the actual value that is set to the FIX message field tag 10.

Note: Throughout this documentation, <install_dir> is the installation location of the Pack for Financial Payments, and n.n.n.n is the current version of the Pack for Financial Payments.

The following steps describe how to use the FIX checksum validation example.

Procedure

  1. Compile the following maps under map source fix_checksum.mms.
    • fxchksm1_utility
    • fxchksm2_validate
    Note: For UNIX operating systems, assign a .mmc extension to the compiled maps.
  2. Run the utility map fxchksm2_validate.
