One of the major issues facing many mainframe installations today is the lack of experienced system programmers. The CICS area is no different. As a result, things such as CICS performance tuning has been relegated to be done when a problem occurs. The reason is quite simple. Today’s performance monitors provide the information, but the system programmer must have a working knowledge to understand what the problem is and how to solve it. Part of this is due to the reduction in education budgets and convention seminar attendance such as SHARE. In today’s environment it is not unusual to see many CICS regions running in a z/OS environment. Using normal performance monitors can take a lot of time to identify tuning areas.
For this reason, C\TREK was developed to ease the work required to identify tuning areas. C\TREK is not a performance monitor. It is a performance and problem determination tool. Although there may be areas where C\TREK and your performance monitor overlap such as displaying running tasks, C\TREK provides more information regarding possible tuning areas. C\TREK provides a comprehensive health check for your system that analyzes over 365 potential problems in your system, many of which are not in plain sight. Using C\TREK, installations have been able to recover between 3% to 10% of the CPU cycles being spent supporting CICS and improved response times. In addition, other important resources such as virtual/real and disk storage have been recovered. In a matter of minutes, the user can identify areas that require attention. In addition, C\TREK provides recommendations on how to correct the problem. C\TREK assists inexperienced system programmers in learning more about CICS and how to solve problems. This presentation will provide information on how C\TREK is a tool like none other that you currently have installed.
The C\TREK™ expert CICS performance tuner™ is a tool used by mainframe system programmers to optimize CICS system performance in a fraction of the time required when using more traditional CICS monitors.
By automating the analysis of vast amounts of CICS data, isolating performance problems and making expert recommendations for corrective action, it enables IBM data centers to save valuable staff time, delay system upgrades, and transition to a more proactive approach to CICS system performance management.
