Operating Systems

The cost and management of IT software pose a huge headache for corporations today. It’s imperative they know what software is installed, where it’s installed and who is using it. Without this information, these companies are more than likely paying for seldom-used, unused or obsolete software. They then run the risk of incurring unnecessary software upgrade and maintenance fees.

Organizations of all sizes can realize financial and operational benefits relating to software by reconciling installed software, quantifying usage and then integrating this information with existing contract and licensing records.

Getting the best value from a z/OS software budget can be extremely challenging. To address this challenge, there’s a solution available today, IBM Tivoli Asset Discovery for z/OS (TADz), that provides information on installed software products and their usage. Just imagine having the ability to save hundreds of thousands of dollars without making drastic cutbacks or having to reduce your z/OS software budget!

TADz defines an inventory of software products installed on a z/Architecture mainframe running z/OS. It provides auditing information about the usage and installation of load modules and z/OS UNIX executables. The TADz Analyzer feature enables interactive reporting through a Web browser, with the added capability of allowing reports to be saved in several formats, including HTML, CSV, Microsoft Excel and txt. z/OS Host Batch Jobs can also be used to provide the same level of reporting.

As shown in Figure 1, the TADz discovery components, Inquisitor and Usage Monitor, are used to collect raw data about installed software products and execution data, respectively. The IQ and usage-import process help construct a picture of installed software products and their utilization. TADz provides information via Web browser reports about:

• Software inventory
• Software product use
• Identification of mainframe storage subsystem hardware
• Discovered machine inventory.

TADz reporting tools provide administrators with a clearer picture of their z/OS systems. This enables an analytical examination of software products using the standard reports provided to assist in answering questions such as:

• What software products have been installed and in which libraries?
• On what z/OS LPAR is the software being executed?
• Which jobs and users have executed them?

User Scenarios

To highlight the areas in which an organization can benefit from using the TADz product, we’ve provided three examples of challenges facing diverse areas of an enterprise as seen through their eyes:
