The need to provide reliable and fast database performance is one of those DBA tasks that can suddenly pop up at any time. Changing conditions can adversely affect a system that was previously exhibiting sterling performance. Users start complaining about slow response time and soon management is pressuring the database team to come up with a solution that solves the issue. Welcome to the wonderful world of database administration!
The problem faced by your DBAs is that there can be multiple reasons behind the degraded performance of their databases. Pinpointing the specific one can be difficult and may involve a substantial period of trying different approaches to narrow down and address the issue. In many cases, providing the required level of performance can be a never-ending proposition as systems and their usage patterns evolve. Problematic database performance can be a recurring thorn in the side of your database team.
What Causes Database Performance Issues?
A complicated question that needs to be answered before tackling the performance problems is what is behind the degraded response time that has end-users flocking to the phone. The issues could have been present since the system was implemented and have only become evident due to growth in the size of the database or an increase in the number of users. Environmental changes such as migrating to a new hardware platform can also contribute to problems in satisfying user requirements.
Some specific areas that are ripe for investigating performance problems include:
Improving Database SQL Code
IDERA’s DB Optimizer can be just the tool to enable your DBA team to address tuning their SQL code. Advanced techniques such as visual SQL tuning diagrams make it easier for your team to successfully identify the modifications that need to be made. Index analysis shows which indexes are being used and can locate missing indexes and offer recommendations to optimize performance. Graphical visualization of wait-time analysis quickly pinpoints the code responsible for system bottlenecks.
DB Optimizer facilitates SQL code optimization across a range of database platforms from one interface for enhanced DBA productivity. The tool supports SQL execution tuning and workload profiling for SQL Server, Oracle, Sybase, and IBM Db2. You can also perform execution tuning on JDBC systems. Database instances on-premises and on cloud virtual machines are supported by DB Optimizer.
Your SQL code may need to be tuned at irregular intervals to address performance issues. Having a reliable tool like DB Optimizer makes it more likely that your team can identify and correct coding issues that are slowing down database response time, keeping everybody happy.
