To address this need, Macro 4 provides the ExpeTune solution suite. ExpeTune is a stand-alone solution which is designed to work alongside Macro 4's leading application performance solution, FreezeFrame.

ExpeTune helps organisations in two main ways to make their most important applications perform better.

• It provides a wide range of performance analysis and identifies system and application areas that can benefit from tuning.
  
  
• It provides a sophisticated rules-based expert system that takes the output from FreezeFrame and provides guidance to expedite and simplify problem determination.

ExpeTune provides support for all of the main z/OS and MVS systems such as DB2, CICS, IMS, COBOL, PL/I and VSAM.

Through its Rules Engine, ExpeTune provides not only outstanding levels of analysis for a wide range of performance problems but also provides a sophisticated level of help in guiding the user to the most appropriate solution to the problem.

ExpeTune and FreezeFrame combine to provide the industry's leading performance solution for all aspects of mainframe usage. This means that your organisation can spend more time on improving its competitiveness and efficiency rather than trying to gather the data and expertise to examine performance problems.
