Oracle Performance Tuning
Oracle Performance Tuning
Do you work closely with your Oracle database? Then you know how your DB is supposed to run during varying periods of utilization. If you are experiencing bottlenecks and you have exhausted your existing troubleshooting channels, it’s time to contact BurkiTech and request our Oracle database performance tuning services. With 20+ years of experience working with Oracle databases, our experts can get your Oracle DB back to optimal performance in no time.
Oracle DB Tuning
Performance tuning requires a different, although related, method to the initial configuration of a system. Configuring a system involves allocating resources in an ordered manner so that the initial system configuration is functional. Oracle Performance Tuning is maximized by finding the most significant bottleneck/s and addressing them with appropriate changes to reduce or eliminate the performance degradation. In most cases, Oracle DB tuning is in response to performance issues not a proactive action. However, there are best practices provided by BurkiTech that can set you up for success from day 1.
Establishing Oracle Performance Baselines
Tuning is more effective when you have comparative data to define the effect of the degradation in question. Most experienced Oracle DBAs understand what performance levels to expect from their system and as a result, know many times if there is an issue without even running diagnostics.
Peak Periods vs. Average Utilization
Being prepared for peak periods is an important part of Oracle database performance tuning. Don’t know when yours are? BurkiTech can help. We have decades of experience tuning Oracle systems and can help establish benchmarks for proper resource planning.
Symptoms of Oracle DB Tuning Problems
According to Oracle, the following are symptoms of tuning problems.
Slow physical I/O
Generally, this is caused by poorly-configured disks. However, it could also be caused by a significant amount of unnecessary physical I/O on those disks issued by poorly-tuned SQL
Latch contention
Rarely is latch contention tunable by reconfiguring the instance. Rather, latch contention usually is resolved through application changes.
Excessive CPU usage
Excessive CPU usage usually means that there is little idle CPU on the system. This could be caused by an inadequately-sized system, by untuned SQL statements, or by inefficient application programs.
Gathering the Right Baseline Data
- Application statistics (transaction volumes, response time)
- Database statistics
- Operating system statistics
- Disk I/O statistics
- Network statistics
