How to optimize your T24 Core Banking environment?

In a T24 Core Banking system, it's not about how nice something looks; it's about how nicely it works and feels. You might use the most expensive and powerful hardware, but the T24 performance and user experience are far beyond your expectations.


Based on our experience, tuning your T24 Core Banking environment is often neglected, but it is crucial for the reliability and performance of your entire system.


Why spend too much on infrastructure costs? A much better way is to focus your T24 optimizations on general environment configuration, file sizing, and timeout settings. In this blog post, you will learn insights about T24 configuration tuning, and in the second and third series, we will share more details about file sizing and timeout settings.


T24 Environment Configuration

Databases are the heart of your T24 environment. If you neglect to tune and optimize this central component, the entire system's performance will suffer. Therefore, keep the following things in mind in your T24 environment configuration tuning activities:



Initial database tuning involves the requirements for setting up, configuring, and troubleshooting on the database level. For example, calculate the number of concurrent connections to your database and set the PGA spaces, and open cursors accordingly, to name a few.


We focus our database-related tuning often on

  • Database block size

  • Redo logs

  • Cache

  • Retention

  • Buffer Flushing

  • Buffer Space

  • Indexes

  • Statistics

  • Another 20+ Oracle parameters


Resize your Tables from time to time because the table space grows fast, affecting the system's performance. We need to identify the file sizes and apply them manually or as part of your housekeeping jobs.


Reduce JOB.LIST / LOB size. JOB.LIST tables are temporary files the COB/service framework uses to populate record keys that the TSA agents will process. Therefore, we need to shrink the database size without deleting the existing records to reduce the unclaimed LOB size.


TCserver performance optimization. Remember that the number of concurrent sessions and the expected throughput limits must be configured accordingly. In addition, there are certain CPU-related limits you should not exceed to achieve optimal throughput. Contact our team to learn more about this topic.


Where to go from there?

Our next blog post will share insights about resizing your T24 files. Also, we will start T24 performance tuning workshops for our customers soon. So follow us to receive more updates about this topic.


Keep up the great work! Happy Performance Engineering!
