AQM Solutions Updates Tools to Identify and Fix Application Problems

Enhancements identify, correct more root causes of application performance problems in z/OS environments

AQM Solutions, Inc. has released version 4.1 of its TriTune software featuring enhanced support for z/OS version 1.9, IMS version 10, and Websphere for z/OS versions 6.0 and 6.1. The company is also releasing an enhanced version of its automated performance and measurement platform, APCTM 4.6.

TriTune and APC are part of an automated AQM (application quality management) solution that identifies potential application tuning opportunities before they escalate into performance problems.

The updated TriTune gives users running IBM WebSphere Application Server version 6.0 and 6.1 visibility into transaction-level activity at the WebSphere Application Server. TriTune provides detailed reports on the system and application class/method activity, SQL activity, and heap and garbage collection activity so users can identify application performance issues originating beyond the mainframe.

Version 4.1 also includes data collection and reporting capabilities for users of IBM DB2 UDB for z/OS Version 9 that help identify potential bottlenecks caused by common programming and application design deficiencies. Users of IBM IMS Version 10 can identify poorly performing transactions and DL/I calls for both Full Function and Fast Path environments using Full Function, DEDB, and HAL/DB databases.

According to the company, “TriTune 4.1 enables users to maximize server region utilization by reporting on the idle time for each monitored CICS transaction server region.” The software also offers insight into many “key CICS areas including temporary storage usage/HWM, Central Storage HWM, DB2 thread statistics, CICS dispatcher statistics, Enqueue statistics, and JVM statistics.”

Version 4.1 can identify problems in a CA IDMS/DB environment and can detect if an application issue is originating from a CA IDMS/DB activity and automatically attribute the CPU response times to CA IDMS/DB application code. It also tracks activity for batch and online applications.

APC 4.6

The company has also added features in version 4.6 of its automated performance measurement and analysis platform to reduce the need for manual performance analysis and broaden application tuning opportunities.

APC version 4.6 offers three new calculation methods for computing annual CPU time, using either the average CPU time of a particular job step, the CPU time of the most- recent job-step execution, or the CPU time of the measured job step as a foundation for detecting detect tuning opportunities.

APC displays the current internal APC Server data in real time, enabling improved analysis of actual, average, and predicted performance of both the currently active job streams and individual job steps.

Users can define summary regions for applications workloads that are distributed across multiple online regions, improving visibility into CICS System Management Facility (SMF); the data can be regrouped and stored together for improved analysis. A filter allows users to choose the specific regions and/or transactions will be handled by the APC CICS SMF feature so APC will focus on the important data regions and eliminates other regions (such as test regions) from analysis; likewise it can exclude transactions like CSS.
