C\TREK™

Performance tuning, Problem Determination

What is C\TREK™

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.

Join Our Beta Program

C\TREK is a unique CICS performance tuning tool that has a high payback in terms of CPU savings and transaction response improvements. It has a health check that looks at over 400 different areas where CICS performance can be improved and provides recommendations. By joining the beta program, you will be able to analyze your system and identify areas that can be adjusted to improve CICS execution. C\TREK is not a performance monitor--it is a performance tuning tool and provides a lot of information not available from your performance monitor. Be part of the experience and join our beta program for the new release of C\TREK.

C\TREK™ provides diagnostic information on the following are

Parameter Definition Tuning

C\TREK™ reviews all the parameters that have been specified for the system and resources such as transaction and program definitions.
C\TREK™ analyzes the System Initialization Table parameters and identifies those parameters that should be reviewed to improve performance.
Reviews the LE options parameters (CEECOPT) and Java definitions and identifies those that require attention

Buffer Tuning

Parameter Definition Tuning

C\TREK™ improves transaction response times by fine-tuning look-aside hit ratios in both NSR and LSR files. It reviews the string allocation by pool and makes recommendations as to how many should be allocated.
Checks for NSR files that don’t have the proper BUFNI allocations. It also includes a series of transactions that help identify poor resource utilization such as buffer fragmentation, buffer monopolization by a particular file, or incorrect pool initialization.
C\TREK™ is the only tool that identifies how many buffers within an LSR pool are allocated to each file. This makes it easy to identify when a particular file is monopolizing a particular buffer in a pool

VSAM File Tuning

Parameter Definition Tuning

VSAM File Tuning

C\TREK™ makes the tuning of VSAM files easy by identifying problem areas that would require a significant amount of system programmer time using other methods, such as traditional monitors.
In addition to assisting in the buffer tuning for NSR and LSR files, C\TREK™ provides recommendations on tuning:
Cluster Definition parameters to ensure that the proper parameters are used, sufficient/correct free space is allocated, the data and index CISZ are optimum, the correct CA size has been defined, the file is not over/under allocated, and identifies files that should be reorganized.
Recommendations for the file cluster definition are provided

DB2 Tuning

Other Tuning Areas

VSAM File Tuning

C\TREK™ provides recommendations and information on how the CICS-DB2 connection may be improved by :
Providing statistics that help determine the number of threads allocated (protected and
unprotected) Reconciliation of threads assigned to the pool DB2 Entries and Command versus the connection thread limit SIT MAXOPENTCBS parameter and the reuse of threads

Abend Handling

Other Tuning Areas

C\TREK™ abend handler captures information regarding typical ASRA (program check abends) but more importantly, it captures information about storage violations and short-on-storage (SOS) conditions.
With the initial information captured regarding the storage violation, the user can quickly determine the active transactions, the damaged area, and the program and task involved.
In some cases, this avoids having to analyze a system dump. In the case of SOS conditions, the abend handler can identify the tasks involved, the amount of storage allocated and used by the task, and the amount of storage requested that caused the SOS condition.

Other Tuning Areas

It's important to note that several areas within CICS can significantly influence resource usage by CICS TS, including storage below the line. It's worth mentioning that C\TREK™ has an exceptional capability to scrutinize up to 180 potential problems that could negatively affect the performance of your CICS system.
