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.
This display serves as the primary interface for navigating the various CICS domains that comprise the CICS Transaction Server. Each domain can be further explored by selecting it, which yields a more detailed view. At the bottom of the display, additional options are available to assist in analyzing the CICS TS system.
To optimize the performance of CICS TS, it's important to analyze its internal resources. The Health (HLTH) option is a good starting point, as it checks for over 400 potential errors or issues. This will give you a general idea of the areas that need to be examined more closely. You can then delve deeper into resources such as Programs, Temporary Storage, Storage Manager, Transient Data, System Initialization Table parameters, and File information to conduct a more detailed analysis.
One of the most crucial aspects of the CICS TS system is its health, which is typically displayed at the beginning. The Health submenu screen provides an overview of the areas that need to be analyzed. The Health option quickly scans over 400 potential issues that could impact the performance of the CICS TS system. Usually, this takes less than 15 seconds, depending on the complexity of the system. Once the scan is complete, the user can review the identified problems and prioritize areas for improvement.
Information regarding how well the Db2 connection is working within CICS TS is available. An analysis of the DB2ENTRY definitions is made and includes a recommendation if the number of threads should be increased. One can view how the L8 TCBs are working and whether they are currently connected to Db2.
C\TREK is a software tool that provides useful information about the programs currently in use. One of its features is the ability to list all COBOL programs in order of their last change date, which can be especially beneficial for program tracking. Additionally, C\TREK allows users to view the CBL control card options used for each COBOL program. Such information is crucial when virtual storage is running low below the line and is especially relevant when a program is linked above the line but still acquiring its working storage below the line due to the DATA(24) CBL option. C\TREK also provides listings of threadsafe programs and those that are still pending conversion, making it a comprehensive tool for managing and optimizing program performance.
The C\TREK system provides an overview of how CICS TS is working. It combines information not only from CICS but also from the operating system. This allows the user to quickly spot any issues like virtual storage, maximum tasks, CPU utilization, real storage, SOS conditions, and DB2 maximum threads. Therefore, it provides a quick overview of how the system is functioning. The C\TREK system also provides additional information from this screen such as the amount of CPU used by the different address spaces.
