Appendix B. Software Validation

Validate software when you want to make sure that the installed software product (or licensed product) has not been damaged or corrupted. The files of a product are checked to make sure they exist and then for total file size, checksum values, and symbolic links. They are then checked against the Software Vital Product Data (SWVPD) database. If the values do not match, the product has been altered or damaged, and you need to contact your software service center.

There are two ways to validate software:

• Use the lppchk command. To check for file existence, file length, and checksum value, enter:

  lppchk -c

  The lppchk command can also be used for a specific product, for example:

  lppchk -c bos.rte

  To check the file links, enter:

  lppchk -f

  The lppchk command verifies the files of an installable software product

  .
• Use the smit problem command and choose the Validate Software option:

  smit problem
