Every Oracle database admin dreads the day when they receive a flurry of complaint calls from users regarding slow online performance.
That’s why, if you’re responsible for managing database performance in your organization, you’ll want to ensure this doesn’t happen. How? By preparing your infrastructure to handle increased loads. Supporting it with performance tuning is also essential, especially when the systems slow down or become entirely unresponsive.
In this post, we’ll consider six important (yet often overlooked) methods and tips to improve Oracle database performance. These will also help you gain the most from your efforts and make sure your environment stays fully operational.
6 Ways to Optimize the Performance of Your Oracle Database
Take a look at the following tricks and tactics to improve Oracle database performance, explained in a simple manner:
1. Maintain Optimum CPU Utilization Levels
It may be necessary to carry out manual tuning processes if, for some reason, you cannot apply the automatic diagnostic features Oracle provides. For this, you must make sure of complete CPU utilization in the user space. Check it to determine whether any non-database tasks are taking up CPU and restricting shared CPU resources.
2. Have a Firm Grasp of System Capabilities
Understanding the importance of baselines is essential to improve performance of SQL query. It helps to preserve a set performance baseline that you can refer to in case of performance issues.
You can do this by keeping an eye out for peak usage periods while measuring current performance. This will enable you to manage bottlenecks easily.
3. Make Use of an AWR (Automatic Workload Repository) Tool
An AWR is extremely useful as it gathers, processes, and maintains performance stats. It also provides a clear picture of your database’s health. The Automatic Database Diagnostic Monitor (ADDM) can help you gain actionable insights from the information you gain here. Together, these tools will save you time and money while enhancing the performance tuning process.
4. Tune Inefficient SQLs Using the Right Tools
The quickest and the least risky way to get rid of Oracle database problems is to tune the SQL using the right query plan. You can also use tuning tools for the Oracle database, such as those provided by Tosska Technologies Limited.
Tosska’s SQL Tuning Expert (TSE™) for Oracle® is ideal for all levels of experience and expertise. Its professional version, Tosska SQL Tuning Expert Pro (TSE Pro™) for Oracle®, can improve performance of SQL query with or without source code. However, these tools work best when you define and measure system issues correctly first.
5. Boost Storage Efficiency
It is possible to improve database performance by enhancing the performance of the storage platform. Review the existing storage for your Oracle database server and see if you can opt for alternatives.
For instance, flash technology offers considerably greater bandwidth and decreased latency to IO-bound workloads. It allows targeted provisioning, thereby boosting performance while eliminating the need to refresh the whole database. The key is to use flash storage for database objects that will benefit the most, leaving the rest in traditional storage.
6. Opt for a Dedicated Database Infrastructure
Sometimes, a common infrastructure platform can be the reason behind reduced performance results. No amount of tuning efforts proves sufficient in such cases. One of the most effective solutions is to provide a dedicated infrastructure to the database. This helps stabilize performance for database workloads and convenient management as well as effective monitoring and security.
