One of the worst nightmares that every new admin of an Oracle database face is a system that is running slow. In case a database suddenly starts to run slowly.
The admin must resort to the immediate performance tuning of the database.
With the help of an Oracle database’s performance tuning, the admin can identify the problems in the system and fix them at once.
Bottlenecks in the database can be identified, and the system infrastructure can be upgraded soon so that the database can manage the increased data loads.
If you find that the performance of your Oracle database is not up to the expected or desired standards, there are ways to fix the problems.
This post will give you an insight into how you can optimize your Oracle database to its maximum levels to ensure that your environment stays completely operational without problems at all.
How can you improve the performance tuning of your Oracle database as a new admin?
There are many things that you need to take care of for this.
If you are not sure how to go about it, make sure to get professional help. RemoteDBA.com is a good place to start.
When it comes to the Oracle database, you will find it to be sophisticated and complex.
You should take up each issue patiently and try to fix them with the following performance tuning tips-
Understand the significance of baselines for performance tuning an Oracle database
To arrest a problem in the Oracle database, you should start with a performance baseline.
Make sure that this baseline is an established one that will help you refer to it every time an issue crops up.
This can be done by identifying the periods where the usage of the database is at its peak.
Here, you can set out the performance targets and have a solid understanding of the data’s capabilities.
The performance of your database should be measured consistently.
It will give you an insight into the precise expectations you have when it comes to the Oracle database’s performance.
This approach should be embraced as it is quite beneficial when it comes to identifying bottlenecks in the database that hampers its performance in the near future.
Deploy the AWR or the Automatic Workload Repository as a monitoring tool for Oracle-
One of the most beneficial features for Oracle performance tuning is the AWR or the Automatic Workload Repository that has the task of collecting, processing and maintaining the statistics of the performance of the database.
It gives you an everyday picture of the health of the Oracle database.
From here, you can use the ADDM feature (Automatic Database Diagnostic Monitor) to get actionable insights on the data that has been gathered by the system’s AWR.
To save both time and money for the organization, you should make the best use of AWR and ADDM for performance tuning of the Oracle database.
Check the Statistics of the database to monitor the performance of the Oracle database-
Besides using the ADDM and the AWR of the system, you should always have a complete compilation of the database, operating system, and application statistics from the system during performance tuning.
Note that merely fixing the issue in the performance of the database is not enough.
You need to give performance tuning top-most priority and make it a central point throughout the complete life cycle of all the applications in the system.
This can be accomplished if you regularly check the statistics of the database and make consistent efforts to refine its process when it comes to collection and presentation.
You will be able to identify the symptoms of all the performance issues inside the data.
You should never ignore the data that would become an influential factor in Oracle performance tuning effectively.
Optimize the utilization of the CPU levels-
You might need manual processes for performance tuning the Oracle database when its automatic diagnostic tools do not resolve the problem.
When working on this issue, make sure that the CPU utilization has been optimized to its maximum levels.
If you check the CPU utilization in the database’s user space, it will verify whether other tasks are not used by the system consuming the CPU of the Oracle database.
If this does happen, it will reduce the limit of the CPU resources that are shared on the system. You need to ensure that the usage of the CPU has been finalized.
This action of yours will take care of all the performance issues in the database.
The system becomes simple, and you get greater clarity for making salient decisions in the organization.
SQL tuning will improve monitoring of the Oracle database-
SQL is one of the most popular languages for messaging primarily because when its queries are sent, data comes back to the system.
However, in most cases, some tools of the client generate inefficient SQL queries. These poorly created SQL queries harm the performance of the database.
You must consider that SQL takes up a lot of resources on the system when performance tuning is carried out.
You should leverage SQL tools of Oracle like the Query Optimizer to keep a close watch on the processing engine of SQL.
This will help you to carry out performance tuning with improved results.
You should take great caution to ensure that SQL does not work against the system but effectively for it.
Therefore, if you are a new admin in charge of Oracle performance tuning, make sure that you keep the above points in mind.
Performance tuning is never a one-time affair.
It should be done regularly with detailed reports so that you can arrest bottlenecks in the database as soon as they arise.
The moment you identify performance issues, you can boost its speed and make the end-user happy.
This goes the extra mile in promoting the growth of any organization and your track records as an efficient Oracle database admin over time too!
