IBM License Metric Tool frequently asked questions


Q – What is the requirement for the IBM License Metric Tool (ILMT) use for AIX?

A – The requirement is limited only to clients running AIX® Express Edition on a medium (IBM Power® 570, Power 770) or high tier server (Power 595, Power 780). Clients in this scenario are required to download, install, and use the IBM License Metric Tool (ILMT) within 180 days of deployment, to help them manage compliance with the AIX Express Edition license restrictions.

Q – Why is it required?


A – Current environments are increasing in complexity and there is a need to provide Power Systems customers with better tools to track their software. IBM License Metric Tool is a no-charge offering that is designed to help clients maintain an inventory of Processor Value Unit (PVU) based and per processor core based software licenses. ILMT is designed to assist clients in complying with the AIX Express Edition license requirements restricting the amount of processor capacity in cores available to run AIX Express Edition in an LPAR.


Q – Is there a charge for IBM License Metric Tool?

A – No, the IBM License Metric Tool is available for no charge to download and includes support at no charge.

Q – Is the IBM License Metric Tool a new utility?


A – No. The IBM License Metric Tool has been available for several years and is the strategic license management tool for IBM. Clients that have used IBM software such as DB2 or WebSphere are likely to be familiar with the IBM License Metric Tool.

Q – Does the IBM License Metric Tool report back to IBM?


A – No. The IBM License Metric Tool collects usage data from multiple servers in the client’s environment and creates reports that the client uses to validate that they are in compliance with the licenses for their IBM software.

Q – Why is IBM License Metric Tool being required for clients using AIX Express Edition on medium or large tier servers?

A – AIX Express Edition is the first product that is specifically limited in vertical scalability by the license. Since there is no hard coded limit inside AIX Express Edition that programmatically prevents it from being used in partition larger than 4 cores and 8 GB of memory per core, it would be easy for a client to unintentionally exceed the license restriction. The IBM License Metric Tool is provided to help clients maintain license compliance.


Q – Why is AIX Express only available for 4 processor-core partitions?


A – AIX Express is targeted for smaller installations as is reflected in the price point. Thus, it is restricted to availability for 4 processor-core partitions only.

Q – I'm using ILMT 7.1 or 7.2.1 and the entries for AIX Express show PVUs. Is AIX price changing to PVUs?


A – No, this is a temporary solution for tracking and reporting. The next release of ILMT will support the new AIX Express Edition pricing model.

Q – What versions of ILMT and AIX can run together?


A – ILMT 7.1.0, 7.2.0, 7.2.1 (April 2010), and next release support AIX 5.2 (32 and 64 bit), 5.3 (32 and 64 bit), 6.1 (64 bit). Installing on AIX 6.1 requires * APAR IZ37466

Q – Are there special requirements for running DB2 on AIX with ILMT?


A – When installing the DB2® database on AIX, you also need the xlC.aix*.rte or higher XL C/C++ runtime environment which you can download from:

Q – What about POWER support for ILMT?

A – ILMT has full support from Power Systems (POWER3™, POWER4™, POWER5™, POWER6™, and POWER7™).


Q – Is Tivoli® License Compliance Manager (TLCM) an acceptable alternative for the IBM License Metric Tool (ILMT) requirement?

A – No. Clients running AIX Express Edition on medium (Power 570, Power 770) or high (Power 595, Power 780) tier servers are required to use ILMT, including new virtualization and AIX core support. While TLCM V2.3 w/FP5 may be an acceptable alternative for ILMT only for PVU-based software, TLCM will not be enhanced to support AIX. The next release of ILMT will support the new AIX Express Edition pricing model.


Q – Has IBM considered making ILMT agent-less, especially given the customer expense to deploy/manage an agent to every client within the data center?

A – An agent-less architecture has been discussed but is not a near-term requirement. Given that ILMT supports several methods of agent installation leveraging a customers’ software distribution solution, customer expense should be minimal.


Q – Which countries are able to order ILMT via Passport Advantage or local ibm.com Web sites?


A – Europe: Belgium, Denmark, Finland, France, Germany, Ireland, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, United Kingdom.
Americas: Mexico, United States, Canada (English and French).
Asia Pacific: Australia, Hong Kong, New Zealand.

Q – What should customers in other countries do?


A – Contact your local IBM representative or Business Partner.

Q – Could clients decide to use another tool, provided it was “auditable”?


A –Yes, with the July 28, 2009 announcement of Tivoli Asset Discovery for Distributed V7.2 [TADd], an optional feature of Tivoli Asset Manager for IT V7.2 [TAMIT], Tivoli Asset Discovery for Distributed V7.2 [TADd] can be used in lieu of ILMT V7.2.

Q – Which software products is IBM requiring that clients track with ILMT?

A – For Power Systems software, initially only AIX Express Edition is required when used on medium (Power 570, Power 770) or large tier servers (Power 595, Power 780) within six months. Additional products running on Power Systems servers may be tracked with ILMT using current release levels with catalog support.
