How to run your Oracle SQL Updates without Compromising Usability
For every database administrator, the big question is “when should I perform Oracle SQL tuning on my Oracle database environment?” The most desirable situation is when you are able to perform these Oracle updates without disrupting the user experience or causing a pile up of customer services calls. When you are able to run a successful update, you are able to avoid disrupting your everyday updates and therefore, you will avoid IT problems. Learn more about Oracle SQL tuning.
Deciding When to Start Performance Tuning with Oracle SQL
Oracle SQL tuning can ideally fit into the following three time periods
- When wait-time analysis shows that end users are being negatively impacted
- When modifying your hardware usage to become more cost efficient
- Day-to-day performance tuning
Get more information about Oracle SQL tuning.
Of course, these are part of the responsibilities of being a DBA and all three of these should be done regularly without compromising user experience. With this in mind, another question arises…
Understanding How to Direct Oracle Performance Tuning
You will want to focus your efforts in these five areas
- Eradicate Wait Events
First take a look at the database performance history and find where the difficulties are coming from. Once you study the wait-time analysis you can proceed to the following points
- Tune the Operating System
Monitor and tune operating system CPU, I/O and memory utilization, this is especially useful when determining whether or not new hardware is necessary for increased system performance
- Database Design
Ordinarily, a poor database design results in poor system performance. If you are able to modify table structures and indexes in accordance with best industry practices, go ahead and do it. You should make small changes if you are not able to change them all at once.
- Tuning Memory
Properly size your database buffers (shared_pool, buffer cache, log buffer, etc) by looking at your wait events, buffer hit ratios, system swapping and paging, etc. In order to eliminate frequent reloads, you will want to pin large objects into memory
- Disk I/O Tuning
Database files needs to be properly sized and placed to provide maximum disk subsystem throughput. Also look for frequent disk sorts, full table scans, missing indexes, row chaining, data fragmentation, etc.
- Application Tuning
Coding optimal SQL queries is often the best way to resolve performance issues. Make sure to stay on the lookout for ways to optimize the efficiency and general performance of SQL queries and resolving latch contention difficulties during off-peak hours.
