Database Maintenance Tool for SQL, MySQL, and Other Popular Databases

Maintaining any database, whether SQL, MySQL, or another type, begins with effective monitoring.

In the database monitoring process, DBAs keep track of key performance metrics, especially the speed of database queries, to help ensure fast performance for end users, whether those users are internal employees or outside customers. For SQL database maintenance and MySQL database maintenance, tracking query details, wait times, and session details are essential parts of the database maintenance plan. By tracking this key data, DBAs are better equipped to identify inefficiencies, slowdowns, outages, and other events that can negatively impact service delivery.

To effectively monitor your database, you’ll first need to identify key performance indicators (KPIs) related to database availability and performance.

The second key element of database maintenance for SQL, MySQL, and other popular relational databases is performance tuning. Performance tuning describes a set of processes and procedures designed to help you make your database queries run as efficiently and quickly as possible.

Whether you’re using a database maintenance tool or attempting to complete the process manually, determining what database statistics and query wait times to monitor is a good place to begin when trying to identify which queries may be underperforming. From there, the basic goals are twofold: 

1. To optimize throughput (the amount of resources used to process a statement)
2. To reduce response time (the amount of time between a statement and its response)

Database monitoring and database performance tuning are at the center of effective database maintenance. Using a tool to automatically monitor your database and queries can help you improve database performance by offering recommendations for tuning your queries and identifying bottlenecks and long wait times for you. 

While there are many best practices to consider for database tuning, the following are some basic principles:

• Avoid coding loops. It’s best to stay away from repetition and overloading when you are querying.
• Be careful when you create an index. The index is a data structure specifically designed to help with retrieval by letting you select rows more quickly. However, if your index isn’t created carefully, it can lead to bottlenecks that negatively impact performance.
• Don’t correlate your subqueries. Subqueries can slow you down because they refer to parent queries and they go row-by-row. If you’re aiming for speed, you need to be strategic at every level of your queries.

Database maintenance is essential to maintaining performance. Simply put, without effective database maintenance, performance and end-user experience can suffer. Some of the main reasons why it’s important to have a database maintenance plan include helping you avoid the following: 

• Poor performance. A slow database can compromise the end-user experience.
• Missing diagnostics. Without deep insights, it isn’t clear what’s causing bottlenecks.
• Compounding issues. If neglected, fragmentation and other issues can overwhelm a system.

With database maintenance, you can improve a database through tasks like performance tuning and SQL query optimization. An inefficient query can be devastating to both your database server and your application server by causing serious and negative impacts on both customer and employee trust in your organization. Your end users expect fast and reliable service, and database maintenance can be essential to helping you more easily meet those expectations.

Not only can MySQL and SQL database maintenance help you detect, analyze, and solve problems more reliably, it can also help you better understand the relationships between the different resources in your database and server (not just the queries themselves). A database maintenance tool can also give you access to system metrics based on the tool’s analysis of query wait times by giving insight into VMware metrics, database server metrics, and helping you identify deadlock victims and survivors.

A high-functioning database can significantly improve business productivity and profitability. The most obvious reason for this is that database maintenance can help improve efficiency. Data retrieval can be slowed by different factors you can prevent through effective database maintenance. By properly maintaining your database, you can also more easily avoid financial losses due to inefficiencies with your servers.

Another way proper database maintenance can help is by allowing you to improve the experience for end users. A good customer experience is essential if you want to avoid turning away customers and can help strengthen your brand. Your customer-facing websites and applications all retrieve data from your organization’s database. Whenever inefficient indexes or suboptimal queries interfere with your data retrieval speeds, end users can have a slow and frustrating experience, leading to lower customer satisfaction. If you want to maintain high customer satisfaction, good database maintenance is one of the most important tools in your toolbox.

SQL database maintenance revolves around identifying problematic queries and tuning them to make sure they’re functioning quickly and efficiently. While you can perform maintenance manually, if you want to perform SQL database maintenance more effectively, you can use a tool to do it.

With a database maintenance tool like SolarWinds Database Performance Analyzer (DPA), you can get help identifying and investigating inefficient queries that could lead to higher I/O, longer wait times, blocking, or resource contention. With a the deep visibility you get from a quality tool, you can also more easily view query details including time ran, execution stats, and relevant metrics. This insight can help you determine what might be causing longer wait times potentially impacting end-user experience and satisfaction. You can also improve SQL and MySQL database maintenance results by correlating query execution delay with end-user impact.

Some of the most powerful database maintenance tools can help automate the query analysis and tuning processes. Depending on the problem your query has, tuning might involve a larger-scale reconfiguration of your database indexes or require small adjustments to a single query command. In many cases, the tuning process consists of simple, repetitive tasks. Automation can be a huge help in the database maintenance process here. Tools like DPA are designed to streamline basic database administration tasks, so you can focus your attention on the tasks that really need your input.

Another way tools can help you with the database maintenance process is by helping you better leverage historical data and trend analysis. Database maintenance tools like DPA can provide you the information you need to more easily prioritize necessary improvements and can help guide your problem resolution efforts.

SolarWinds Database Performance Analyzer is built to enable effective database maintenance—whether it’s SQL, MySQL database, and maintenance of other popular databases.

With DPA’s SQL query optimization features, you have the built-in tools you need to target, optimize, and better manage SQL queries. With DPA, you can quickly identify and investigate inefficient queries leading to problems like longer wait times, higher I/O, resource contention, or blocking. Since DPA offers built-in, round-the-clock database monitoring, you can also view both current and historical data, including execution stats, time ran, and other relevant metrics, and use them for directing your tuning efforts.

Database Performance Analyzer is designed to offer thorough response time analysis with the ability to correlate query wait times with end-user impact to better detect anomalies. The tool is built to pull each instance once per second to determine active session performance, then alert you if it detects delays. Whenever a SQL statement experiences a significant increase in wait time, you can use DPA to quickly drill down into the problem and identify its root cause. 

By running table tuning analysis at the end of the day every day, Database Performance Analyzer is designed to help you catch both widespread and minor performance issues related to inefficient queries and indexes. By offering visibility into problems of various severities, DPA can also help you more easily determine which problems should be prioritized and which ones can wait. Thanks to DPA’s clear, unified dashboards, you can get visibility into problem query details to help you quickly decide if you should tune the query, add an index or columns, address fragmentation, or take some other action.

Another way DPA helps with database maintenance is by offering DBAs actionable advice they can use to help prioritize performance issues and for next steps. The tool is built to leverage historical trends and current data to generate SQL Server tuning advice. Not only can this advice help you tackle query problems in the short-term, but you can use it to create a database maintenance plan to help prevent future performance issues.
