Why Choose SkillBuilders’ APEX Tuning?

Of course we can enhance the performance of SQL statements and APEX page components. But we also have the team experience to apply a holistic approach to tuning involving developers, DBAs, SysAdmins, web developers. Our team synergy ensures all components (end-to-end) are tuned. Our elite team has worked on several customer challenges involving all aspects of APEX Tuning.

We understand the difference between two distinct tuning objectives – performance (user-experience) and Scalability (how many users can we support). Though one goal often impacts the other , the focus of the project is dictated by customer needs. 

We possess a broad range of experience in APEX application tuning. From tuning APEX page components to session state management and distributing incoming user requests across multiple servers or instances can ensure optimal resource utilization and enhance the user experience and / or scalability.

Cost-Effective Solutions: APEX tuning not only enhances performance but also optimizes resource usage, potentially leading to cost savings in hardware and infrastructure expenses.

Why Guess When You Can Know?

How many users can my APEX application support?

What’s the application (pages) response time?

Am I losing customers because of bad response times?

Can I accelerate the image delivery?

I hope to add 50 new users a day. Will my system support this?

Am I wasting money by allocating too large of a server?

Are the connection pools optimally sized?

Could the SQLs be tuned?

Know what to expect! Have SkillBuilders bring its people and tool kit to the case and find the answers to these questions!

Our Tuning Process:

Though one objective often impacts the other, there are two distinct objectives related to tuning – performance (user-experience) and Scalability (how many users can we support).

How do we ensure an application is performant and scalable? Our developers, DBA, SysAdmin and Web Tier experts work together to perform the following tasks.

  • Performance Assessment: Our team conducts a comprehensive review of your APEX applications. With the help of APEX Monitoring and APEX Debug, we’ll look at page execution times, page load times, etc. and compare these to the response time goals as stated by the customer.
  • Scalability Assessment: If scalability is in question, load tests are conducted (k6, jMeter) to determine at what user count the application performance falters or the application starts failing.
  • Application Design Review: Evaluating your application’s architecture and design to identify any structural inefficiencies that may hinder performance.
  • Web Tier Tuning: Apache, Threading Model, Connection Pools, httpd.conf (image files, static content, reverse proxy, ie how Apache routes to Tomcat/ORDS, Session Stickiness (in a multiple web server environment)
  • Resource Management: Properly managing resources, such as memory and CPU, is essential for optimal performance. We can fine-tune resource allocation to ensure smooth operation.
  • Caching Strategies: Implementing effective caching mechanisms can significantly reduce database load and improve application response times. We apply caching strategies tailored to the customer’s specific application requirements.
  • SQL Query Optimization: At the heart of every APEX application are SQL queries. Ensuring these are optimized can dramatically improve performance and scalability. This involves reviewing SQL execution plans, optimizing queries, sometimes redesigning database structures, looking for opportunities for result set caching, ensuring best use of bind variables and more.


  • PL/SQL Code Reviews: PL/SQL is a powerful procedural language that often gets embedded within APEX. Like SQL, this code needs regular reviews to ensure the code is performant and scalable.
  • Database Performance Tuning: We will uncover incorrectly set initialization parameters affecting all aspects of the database.
  • OS Performance Tuning: Again we will uncover and correct incorrectly set kernel parameters that can affect caching, CPU scheduling, disk I/O, memory management, and other performance-related settings can be tweaked to optimize system performance.
  • Hardware Tuning: When we discover poorly performing disc devices we will make appropriate recommendations for improving performance , e.g. solid state disc devices or segregation/isolation of critical database files such as redo logs.
  • Network Optimization: The latency between the APEX application and the Oracle database can impact performance. Implementing caching, Content Delivery Networks (CDNs), and other strategies can make a difference.
  • Scaling and Load Balancing: Distributing incoming user requests across multiple servers or instances can ensure optimal resource utilization and enhance user experience.

Post-Tuning Support:

Our commitment to your success doesn’t end with tuning. We offer ongoing support and, if desired, monitoring, to address any new challenges that may arise as your application evolves.
