Why do I need an SQL server tuning tool?

Tuning SQL server queries is essential for optimizing query performance and is part of all good database management software. If queries are running slow or failing, then performance monitoring and SQL tuning can help to make your code more efficient. However, doing this manually without a query optimization tool is difficult because you need to do everything manually with limited functionality.

Finding database queries that aren’t up to scratch is a painstaking task. Server optimization tools are invaluable because they allow you to view queries with poor performance and locate resource bottlenecks more easily. They also allow you to gather performance statistics which can help to improve SQL queries in the future.

Many tools can do this automatically with alerts and automated responses so that queries will be improved without the need for user intervention. Using an SQL server tuning tool helps to improve your server performance and increases your responsiveness to managing server problems. For example, with a Structured Query Language monitoring tool, you can tune SQL server queries before you start experiencing performance issues.

How to Optimize & Tune SQL Queries

SQL query optimization is part of the business process. Your SQL queries might not be bringing back the right information because the person that wrote the query didn’t understand the data request and hasn’t studied the structure of the database. So, optimization begins right at the creation of the database and each time a request for data arises.

  1. Understand the core data of the business Focus the design of the database on tables that hold the core data of the business and normalize tables accordingly.
  2. Make full use of indexes Read through the list of indexes on the tables that you are joining together and make sure you use these as often as possible. Look out for composite indexes, adding an extra field in your join could speed up the search.
  3. Find out how the RDBMS implements WHERE clauses Some RDBMSs work through the lines in the WHERE clause from the bottom up.
  4. Sequence joins in the WHERE clause Order your WHERE clause to filter out the most records with the first join. Make joins on ID fields first and leave text field joins to the very end of the query.
  5. Tighten up joins Avoid outer joins wherever possible. Make sure that you have fully linked records in tables and that you are not creating a “times.”
  6. Avoid comparisons Make concrete links between tables first and leave filters that use lists or wildcards to the end of the execution.
  7. Look for resource spikes during execution Queries that hit the performance limits of the RDMS will always take a long time to run.
  8. Use SQL performance tuning tools Experienced programmers understand SQL performance intuitively; everyone else needs a tool that can trace the implementation of the SQL line by line and identify joins that require excessive resources.

Site24x7 SQL Query Monitoring

Site24x7 Infrastructure is a cloud-based monitoring system that covers database monitoring. It is able to monitor database instances that are managed by SQL Server, MySQL, Oracle, PostgreSQL, DB2, MongoDB, VoltDB, Cassandra, CouchDB, and ClickHouse DBMSs.

Database monitoring is just one of the responsibilities of Site24x7 Infrastructure. It also monitors networks, servers, applications, services, and websites. Its purpose is to link together all of the application stack that lies behind a web page or a user-facing software package. By the use of this application dependencies map, the system can perform root cause traces to identify the cause of performance issues in front-end systems.

The database monitoring features of Site24x7 collects statistics on read and write activities, slow queries, aborted clients, threads, and open files. It monitors total temporary tables, space used by temporary tables, temporary tables on disk, and temporary table removal. The system also tracks database connection usage, aborted connections, and the maximum number of used connections.

Thanks to the application stack map, the Site24x7 Infrastructure system can spot when performance problems in other parts of the system are the cause of database performance problems. It can identify the resources of the supporting host that are used by the database and spot when those resources are running low.

Site24x7 Infrastructure database monitoring includes a system of performance and resource availability thresholds. This generates alerts if a problem arises or if resources are running low. The alerts can be forwarded to key staff by SMS, email, voice call, or instant messaging post. This alerting mechanism automates system supervision because it removes the need for human involvement unless things go wrong.

4. ManageEngine Applications Manager (FREE TRIAL)

ManageEngine SQL Monitoring

Databases are among the many categories of applications that are covered by ManageEngine Applications Manager.  This service can monitor non-SQL databases, such as NoSQL, in-memory, and bid data systems as well as SQL-based relational database management systems.

The Applications Manager monitors the performance of databases, looking at the metrics of normal operations, such as resource usage, buffer cache size, user sessions, and locks. It particularly tracks SQL query performance.

The monitor follows queries before they even get to the database. It starts by tracking the execution of code that implements database access as it sends the SQL that is going to be executed. This strategy, including logging the return of results and how they are used, means that the monitor records the full cycle of interaction between an application and the database.

Overall performance is then broken down per step. So, the system manager can see which action is underperforming if user-facing software starts to perform badly. If the issue seems to be with the database, the metrics gathered by the Applications Manager make it clear whether the issue is with lack of physical resources, a problem with database objects, or an error in the SQL statement.

SQL analysis identifies system errors and structure problems as well as query execution plans. The whole purpose of the Applications Manager’s database monitoring service is to quickly identify the root cause of performance issues.

ManageEngine Applications Manager runs on Windows Server and Linux. It is available in three editions: Free, Professional, and Enterprise. The Professional edition gives access to 500 application monitors and there are advanced features in the Enterprise edition. The Free edition can only run five system monitors. ManageEngine offers Applications Manager on a 30-day free trial.

SQL Query Optimization FAQ

Which software is best for SQL?

There is no “best” SQL software. Some programmers prefer to write SQL in a plain text editor, while others like SQL editors that highlight keywords and match up brackets; non-technical staff would benefit from SQL assemblers that suggest syntax and clauses.

Is SQL software free?

There are many free SQL optimizers and editors available and many of them are no use. Finding the right software for SQL creation and optimization is a personal journey.

What is SQL Query Analyzer?

There is no single product called SQL Query Analyzer, rather this is a type of utility that scans existing SQL code and suggests performance improvements. For example, the SolarWinds Data Performance Analyzer includes an SQL query analyzer.

How do I monitor SQL performance?

SQL query performance monitoring requires a number of different factors to be logged while the query is running. This is difficult to perform manually, so you really need to invest in monitoring software that supports that task.

What is the best free SQL database?

The best way to get SQL database software for free is to acquire it as part of a bundle of services, such as a database system that is included with a web hosting package. It is important to get an SQL database system that is widely used and is supported by extensive user training and online help advice.
