Step 1. Activate the usage measurement collection function

The installation must activate the measurement collection function on every OS/390® and z/OS® image participating in usage pricing. The SMFPRMxx member of SYS1.PARMLIB controls the collection process. You may be required to make changes to your current SYS parameter to activate the collection of SMF type 89 subtype 1 records. Although you can continue to collect other types of SMF records, usage pricing only requires the collection of type 89 subtype 1 records.

Where a processor is running OS/390 or z/OS under PR/SM™ (or equivalent) or under VM, the measurement function must be installed and activated to record the required product usage for:

All eligible products running in all OS/390 or z/OS LPARs
All eligible products running in all OS/390 or z/OS systems under VM
All copies of each eligible product, including those running on non-production LPARs or systems

All OS/390 or z/OS images running on processors designated as being a part of a parallel sysplex for the purposes of measured usage pricing must also activate the measurement function.

Note: After changing SYS1.PARMLIB and activating the measurement function, you must reinitialize all copies of DB2® before you can measure DB2 usage.
