It is strongly recommended that you check the file integrity of GAV tables before using them in your projects. The process uses a Trillium-provided utility to determine the hash value of the newly installed files. To complete the validation, you compare that value to the one provided in a text file that was delivered with the tables.
Note the following guidelines:
There are no hash files for ACE tables.
If you have purchased Global (GA) GAV Tables, hash files are available for rdata (country data) but not for kdata (knowledge base data).
