IBM will be discontinuing support for two older versions of the IBM License Metric Tool (ILMT) soon, and recommends migration to ILMT 9.x. Even though many users are still on v7.5, IBM will discontinue support for the product in April 2017. IBM has listed resources to assist with planning your migration.
Why would someone want to use IBM’s License Metric Tool (ILMT)?
IBM’s Passport Advantage Agreement (IPAA) is the master document for all of IBM’s distributed software – PVUs, RVUs, users, etc. that could be downloaded through Passport Advantage or Passport Express. The document briefly explains by default every IBM client is licensed at full capacity unless they install ILMT and run it as described.
With ILMT, a client can license their distributed environment by sub-capacity. This greatly favors any environment with virtualization and reduces the amount of PVU and possibly RVU-metric software required. Sub-capacity allows you to license only the processing power allocated to IBM’s software rather than the entire server. IBM offers ILMT at no cost for the license (D561HLL) or annual support (E0256LL).
