Software vital product data

Certain information about software products and their installable options is maintained in the Software Vital Product Data (SWVPD) database.

The SWVPD consists of a set of commands and Object Data Manager (ODM) object classes for the maintenance of software product information. The SWVPD commands are provided for the user to query (lslpp) and verify (lppchk) installed software products. The ODM object classes define the scope and format of the software product information that is maintained.

The installp command uses the ODM to maintain the following information in the SWVPD database:

• Name of the installed software product
• Version of the software product
• Release level of the software product, which indicates changes to the external programming interface of the software product
• Modification level of the software product, which indicates changes that do not affect the external programming interface of the software product
• Fix level of the software product, which indicates small updates that are to be built into a regular modification level at a later time
• Fix identification field
• Names, checksums, and sizes of the files that make up the software product or option
• Installation state of the software product: applying, applied, committing, committed, rejecting, or broken.
