Specifies the name or address of an optional 8-byte input field
into which you place the qualifier of the product. You might wish
to use this parameter when there are several iterations of the same
product running on one system and you want to record usage data for
each iteration, rather than grouping all product usage together. If
a product is running multiple times on a specific system, you can
record usage based on individual system use of the product. A subsystem
product could use as the qualifier the subsystem name under which
each copy of the product runs.Note: The Usage Reporting
Program (IFAURP) will not consider the product qualifier as
part of the product ID when the product name is "DB2®".
