How did we improve lease and platform performance?


Improvements in IBM TRIRIGA Performance

By Rick Rhea & Jay Manaloto

What has the IBM TRIRIGA performance team been up to? Over the last few years and last few releases, our performance team has focused on areas that aren’t normally covered by our standard benchmark tests, and on tools that can help customers to resolve performance issues on their own. If you’re interested, here are a few of our recent improvements in lease and platform performance.

  • Lease Benchmark Testing: Not only are database server and process server resources especially important, but using multiple process servers improves performance.
  • New Recommended Indexes: Several additional indexes were identified and added to the best practices to obtain the best response times and resource utilization of the database server.
  • Lease Journal Entries: By redesigning journal entry processing with parallel and batch processing, and multiple process servers, our test results took only about 2.5 hours instead of over 90 hours.
  • Platform Enhancements: Dynamic workflows can now pass and return parameters, the Query task can now return the number of records instead of the actual records, and the Trigger Action task can now run the asynchronous event that occurs after the transition by a user other than the currently logged-in user.
  • BIRT Reporting & Lease Disclosure Reports: In Version 3.6.1, the reporting was modified to improve running on a separate BIRT server, and to avoid the problematic “params.displayText”.
  • Performance Analyzer Tool: In Version 3.5.3, this tool was introduced to allow a customer to run specific logging types without using the Admin Console, and to view easy-to-read reports.
  • Module Level Associations, Early Adopter Feature: In Version 3.7.0, the platform was enhanced to support Module Level Associations (MLA) tables where the records in the IBS_SPEC_ASSIGNMENTS table are distributed into smaller tables that are created by module type.

By applying the above finding and tools, our recent IBM TRIRIGA 10.7.0 / 3.7.0 release has demonstrated a significant improvement in performance over previous releases. But we’re not done yet! Our performance team will continue to dig deeper into weaker areas or potential opportunities to make our products stronger or faster. So stay tuned for any upcoming developments!

Note: For future releases, “Module Level Assignments” will be renamed “Module Level Associations”.

How do you analyze IBM TRIRIGA with the Performance Analyzer?


Starting in version 3.5.3, IBM TRIRIGA Application Platform includes a Performance Analyzer. The Performance Analyzer is a system tool that helps you to diagnose system performance issues.

Performance Analyzer overview

  • The Performance Analyzer provides a more streamlined approach to troubleshooting performance issues than the traditional IBM TRIRIGA performance log analysis.
  • The Performance Analyzer helps you to better isolate and analyze the causes of performance issues by generating a log that is more targeted at the problem area. When you contact IBM to report a TRIRIGA performance issue, you might be asked to run the Performance Analyzer and provide the resulting data.
  • When you select the performance timing categories that you want and start a performance run, the analyzer rolls the performance log and captures data while you do the process or actions that cause the slowness.
  • When you stop the performance run, the analyzer automatically loads the performance data and does a high-level analysis that shows the longest running item in each category in the performance run. A result summary of the performance run shows the top events that took the longest time to run. You can further analyze the data by reviewing the result details where all the selected category data is displayed.
  • You can also upload an existing performance log to the analyzer and the analyzer does the same high-level analysis of the data.

The Performance Analyzer has the same base requirements and restrictions as the traditional TRIRIGA performance logging, which includes nightly rolling, space consumption, and logs for all users. Details include…

What is the Performance Problem Decision Tree?


The Performance Problem Decision Tree helps you to troubleshoot system performance issues in IBM TRIRIGA. The decision tree progressively narrows the focus of your issue and provides targeted information for troubleshooting the issue.

IBM TRIRIGA Application Platform 3.5.3 introduced the Performance Analyzer. The Performance Analyzer is a platform tool that helps you analyze and diagnose issues in system performance. You are encouraged to use both the Performance Analyzer and this decision tree to help you troubleshoot system performance issues.
