OVERVIEW
Finding and tuning the performance bottlenecks hidden within thousands of batch jobs and online transactions is a vital task. Without it, processing costs escalate, response times deteriorate and customer service suffers. Knowing where to start looking for performance problems can be a challenge, however. ExpeTune meets this challenge by identifying the applications and z/OS subsystems that need tuning, and showing you exactly how to improve their performance.
ExpeTune is a leading z/OS application performance management solution that can be used on its own or in combination with FreezeFrame, which pinpoints performance problems through detailed observations.
ExpeTune produces a wide range of performance analysis reports to identify potential problem areas that require investigation, together with a rules-based expert system that guides the user to the most appropriate solution.
KEY FEATURES
- Identification of tuning candidates
To help you decide where to focus your tuning efforts, a Watchlist is created from SMF data, showing any batch or online applications that exceed thresholds decided by you, such as CPU usage or elapsed time - SAS and MXG support
If you already use SAS and MXG for your statistical data, ExpeTune can analyze their databases to build a Watchlist of tuning opportunities - Scheduling of FreezeFrame observations
You can view the Watchlist and submit FreezeFrame observations for selected entries, to provide additional detailed performance analysis - Observation session analysis
ExpeTune can analyze any FreezeFrame application observation and report on potential issues such as excessive use of monitors and traces, use of expensive database services and poor run-time routines - Expert knowledgebase
A comprehensive knowledgebase provides expert advice on how to correct the performance problems highlighted by ExpeTune and FreezeFrame - CICS monitoring
CICS transactions are monitored in real-time and a FreezeFrame observation session can be initiated automatically if a transaction takes too long to execute - SMF data analysis
Performance reports are produced from raw SMF records to provide operational insight in a wide range of areas such as CPU usage by LPARS, CICS regions and jobs - System auditing
A powerful audit tool can examine many sources of statistical information to reveal a wide range of program and non-program related tuning opportunities, without the need to execute any target code - Graphical reporting
A range of charts, showing MIPS usage and system CPU usage, allow you to analyze resource consumption from multiple perspectives, including date and time, application category and system name
