Four Cornerstone can help you carry out Oracle SQL tuning. 

A slow database is not only a nightmare for its users; it can also cost your business in terms of time and efficiency. Instead of waiting a long time for a response, the user can use that time doing something more productive.

The good news is that you could do some performance tuning on your Oracle database in order to help it perform faster and better.

Database administrators usually know what areas to tune.  Poor performance can stem from the following scenarios:

1. Flawed database design.  You can do some performance tuning on the database design, such as checking if you have configured the data replication and aggregation tables correctly, or if you have de-normalized them properly.

2. Bad SQL code.  A majority of performance slowdown that happens on Oracle systems are caused by badly written SQL

3. Improper timing of batch tasks.  This could slow down your database, especially during peak hours.

4. Incorrect sizing of buffers.  Incorrect sizes for buffers, like the buffer cache, shared pool and log buffer, could lead to the need for some memory tuning.

5. Database contention.

6. Problems with your operating system.

Does that sound like a lot of places to look at?  Do not worry, because you have a wide array of utilities and tools that you could use.  Some of these tools are:

• Automated Database Diagnostics Monitor

• TKProf

• Statspack

• The Tuning Pack in Oracle Enterprise Manager

• Begin and end stats monitoring


More than that, you also have a large community of Oracle experts who could help you with your performance tuning.

Pressed for time?

However, if you are having problems figuring out what to tune or, much more, how to tune it, then maybe it is time to call in the experts.

SQL Tuning

SQL tuning is done to improve the execution or production plan with as few PIO physical reads and LIO buffer gets as possible.  SQL tuning involves these processes:

• Minimizing full-table scans on large tables

• Caching full-table scans on small tables

• Using the proper index

• Effectively managing your tables and data

It might seem like SQL tuning is a walk in the park, but we assure you that it is not.  In fact, SQL tuning is very complicated and its processes, how-tos, and solutions could easily fill a thick book.

If you have the manpower or the time to learn the ins and outs of SQL tuning, then you are lucky.

However, chances are that your business operations will not have that much leeway for mistakes or delays.
