Maintaining and improving database performance is a critical part of a database administrator’s (DBA’s) job. Slow and under-performing systems lead to dissatisfied users or customers. This in turn negatively impacts a business’s ability to compete and results in lost revenue.
In the competitive landscape of modern commerce, customers are likely to abandon a solution that doesn’t meet their expectations or takes too long to respond in favor of an offering from a market rival.
Database profiling can help DBAs keep their systems performing well.
Database profiling is a term describing the process of identifying and diagnosing issues affecting database performance so they can be addressed by the support team. Through profiling, DBAs can obtain the information they need to tune database performance without wasting time and effort trying to track down the source of problems.
Profiling requires insight regarding the inner workings of the database under review. This is best done with a dedicated tool tailored to the database platform on which the ill-performing instance is running.
DB Optimizer is such a tool, designed to save DBAs time and quickly get to the root of performance issues. It provides the following benefits:
Let’s take a closer look at using wait-time analysis to identify performance bottlenecks.
Wait-time analysis is a technique that has gained popularity as a method of performance tuning and offers some advantages over traditional trace analysis.
Trace analysis requires DBAs to have some idea of what they are looking for and is most useful when a performance problem has already been isolated. Wait-time analysis is better suited to quickly locating the problems that need to be addressed.
Wait-time analysis works by providing DBAs with a list of the time delays impacting a database that are causing users to wait for requested information. It looks at queries, explain plans, and stored routines to give a complete picture of where bottlenecks are occurring.
DB Optimizer makes various categories of wait event analysis available for the supported database platforms. Examples include details on the wait-time for CPU events, I/O, locks, and memory access. Data is presented graphically to make it easier to understand.
Armed with this information, DBAs can go directly to the source of the specific performance problems plaguing their systems.
DB Optimizer provides DBAs with the information necessary to tune relational databases on the Oracle, SQL Server, Db2, and Sybase platforms from a unified interface. Consolidating tuning capabilities for multiple platforms in this way aids productivity as DBAs become familiar with the tool’s features.
In multi-platform database environments, eliminating the complications involved with using additional tools will be greatly appreciated by the team.
Some of the features that make DB Optimizer a valuable tool for database teams searching for performance gains include:
