SQL Performance Tuning: 5 Things to Do for Faster Results

Is your SQL Server falling behind in terms of performance? Are poorly-written queries slowing down your applications? Before you set out in search of professional help, make sure you’ve tried everything you could to resolve the issues you’re facing on your database. 

Many problems related to SQL Server can be handled easily with preventative maintenance, patches, and a few activities performed on a regular basis. You can always depend on our SQL performance tuning tools if nothing works for a particular situation. But before that, read the five important things you can do to fix database performance.

5 Things to Do for Effective SQL Performance Tuning

Given below are five simple things you can do to improve database performance:

Check if your SQL Server is up-to-date

An older query engine out of active development is bound to get you in performance-related trouble every now and then. Moreover, the newer versions have much better diagnostic support and will make things faster in multiple ways.

For starters, they come with new versions of the query optimizer. Although Microsoft provides a few tweaks here and there in its service packs, major version releases contain all the best improvements. Other advantages include:

  • Bug fixes
  • New CPU instruction sets
  • Latest software development techniques

Even a 32-bit to 64-bit upgrade can go a long way in improving database performance. This will help regardless of whether you are performing SQL tuning for Oracle or SQL Server.

Increase the Memory

Maxing out its memory will make a difference in its performance. This is because the database utilizes it to cache data instead of making additional trips to disk. Additionally, you gain more memory for cache query plans and can use it for larger sorts and joins. Another advantage is a potential decrease in disk and CPU utilisation, which further helps with SQL performance tuning. Just remember to raise the memory configuration in your SQL Server so it actually makes use of the new RAM.

Open Task Manager

If things remain slow after you’ve increased memory and upgraded your SQL Server,  it’s time to open Task Manager. Sort by CPU, followed by memory, and close any running apps, processes, or software that’s eating up space and you’re unaware of. Configure exceptions for antivirus software, if you have anything installed.

Windows may also be caching data for file system access, stealing RAM from server-side apps such as SQL Server. This can be checked by looking at the Cached number in the “Physical Memory (MB)” tab.

Check the Event Log

This includes both – the Windows Event Log and the SQL Server Log – as they both have potentially useful information. In case Windows or SQL Server are facing any sort of issue, these logs will certainly have more details about it.

You’ll know whether SQL Server is lagging due to hardware-related problems, facing long disk wait times, or dumping core. There may be other services with issues on the server that you can find out about here.

You can also read our post on SQL tuning for Oracle for some useful tips.

See if SQL Server alerts are set up

It is important to ensure these alerts are configured. They will, in turn, help you make sure you’re updated on everything that’s happening in SQL Server. As the person in charge of the database, you need to be aware in case the storage is falling short or other serious errors in SQL Server.

SQL Query Performance Tuning: A Look at Various Plan Formats

SQL query performance tuning

Database professionals are often familiar with the fundamental maintenance tasks for SQL Server. However, they may have to perform the optimization of SQL queries and keep an eye on query plans from time to time.

This may lead to confusion as to which type of query plan they should use. Here, we will cover the different types and formats of query plans and how to obtain them for SQL query performance tuning.

Query Plan Types and Formats for Efficient SQL Query Performance Tuning

To start with, there are two major kinds of query plans: the estimated and the actual execution plan. Users can obtain these in three distinct formats – text, graphical, and XML.

Keep in mind that users who wish to create these execution plans will require SHOWPLAN permission first. This is also true in the case of query plans and SQL tuning for Oracle.

Text-Based Query Plans

This type of plan can be procured using one of the three methods given below:

  • Set SHOWPLAN_Text – The query will not be run by SQL Server, but this method should fetch information about the manner in which queries run. In short, this statement will display information regarding the Estimated Execution plan.
  • Set SHOWPLAN_All – Again, SQL Server won’t run the query but it will fetch thorough details regarding query execution, i.e the way it executes them and which resources it uses for this purpose. You can also get more details about the Estimated Execution plan.
  • Set Statistics Profile – SQL Server will run the statement and display comprehensive data regarding query execution. This information includes the precise number of rows that were actually processed and all the resources that have been utilised for executing these queries. This command will also fetch details regarding the Actual Execution plan.

Graphical Query Plans

This format allows users a look at numerous sources of information and plenty of tooltips in SQL Server Management Studio.

Note that if you want to view the Estimated Execution Plan, you can do so once you press Ctrl+L in the query window. To view the Actual Execution Plan in the same results set, press Ctrl+M.

XML Based Query Plans

This type of query plan gives the most comprehensive details of the plan in the extremely portable XML format. You can obtain query plans in this format using two methods:

  • Set SHOWPLAN_XML – The query doesn’t run but returns detailed information about how the statements execute and the resources used for the query execution. SQL Server also displays a detailed XML document that has the Estimated Execution plan.
  • Set Statistics XML – SQL Server runs the statement and shows information regarding query execution in exhaustive detail. This includes information on the actual number of rows processed as well as the resources applied in the query execution. It fetches a properly created XML document consisting of the Actual Execution plan, helping in SQL query performance tuning.

How these Query Plan Formats Differ in Use

The graphical format is usually the simplest to read which is why beginners usually start with them. The best way to read graphical query plans is from right to left moving upwards from the bottom while following the arrows. Additionally, you can make things easier with the Zoom In and Zoom Out functions.

You can view further details from Graphical plans with the help of ToolTips. All you have to do is point your cursor at the icon you want to know more about. While this is an extremely useful feature, it can get complicated to view every detail on a complex query with the help of this tool.

This format also forms the link between the Text and the XML formats. This is because you can save Graphical Plans in XML format. If you’re trying to perform SQL tuning for Oracle, you may consider a SQL tuning tool depending on your requirements.

Text plans, on the other hand, are more difficult to read and lack simpler rules to understand them. However, they prove useful for those who have experience with execution plans and know what and how to look for.

Optimization of SQL Queries: Database Engine Tuning Advisor

optimization of SQL queries

If there is one complaint business users may have about their production database, it is slow performance. Database professionals, therefore, often try to focus strictly on finding out and resolving the source of the issue in the database.

The Database Engine Tuning Advisor (DTA) is one of the best tools in this regard. It helps DBAs analyze workloads and uncover areas that can be improved. In this blog, we will discuss the working of this tool along with a few additional details.

What is the Database Engine Tuning Advisor?

It is a tool that assists with the optimization of SQL queries and was introduced in SQL Server 2005. Before it, SQL Server had a feature known as the Index Tuning Wizard.

The DTA is designed to assess a workload and provide recommendations to boost query performance. Some of its suggestions include:

  • Making partitions
  • Incorporating indexes
  • Adding statistics (this helps resolve the issue of automatic statistics not getting created despite the auto_create_statistics option being ON)

Apart from locating every type of potential for enhancement, the Oracle Database Engine Tuning Advisor will build a T-SQL script for users to execute in order to carry out the recommendations made by it.

How to Launch the DTA for the Optimization of SQL Queries

You can commence its use through multiple methods:

  • Open the Start menu, scroll to the SQL Server application group and look for the Performance Tools folder.
  • If you’re using the SQL Server Management Studio application, you can select the tool from the Tools menu.
  • The SQL Server Profiler also has this tool in its Tools menu.
  • You can find it with the select analyze query in DTA on the SQL Server Management Studio Query menu. This also enables you to pass a T-SQL section to the tool for analysis.
  • Open the Command Prompt, type “DTA -?” for a glimpse at the available alternatives.

Normally, you can create a workload by collecting multiple statements in a file or with the help of the SQL Server Profiler. An important point to bear in mind is that the workload being sent to the Advisor for evaluation needs to be representative of the average workload.

What the Database Engine Tuning Advisor Does

The Database Engine Tuning Advisor makes recommendations on the basis of the workload you send for analysis. Therefore, a limited workload will result in inadequate recommendations. The best thing to do is to collect the workload through the Profiler, save the results in a text file, and send the trace to the Advisor.

The SQL Server Profiler plays an important role in the optimization of SQL queries. It can be launched from its location in the SQL Server application folder (in the Start menu) or among the list of tools in the SQL Server Management Studio.

In case you want to know the properties of the new trace, follow these steps –

  • Click on the dropdown list in the dropdown menu of the tool window (for the trace template) and select Tuning. The trace template gathers the events considered necessary by DTA.
  • Select the ‘Save to file’ and type in the file name you want before passing it to the Database Engine Tuning Advisor once the trace is complete.

Selecting a SQL Server Database Version for Your Company

SQL Server database and SQL

Choosing the right version of SQL Server is important for the performance you desire. If you’re installing an older one because your organization’s management prefers an older build or the vendor is unable to support newer versions, it is important to let them know which version your company needs, and why.

For this reason, we will discuss some popular versions of SQL Server from older to newer and mention their advantages in this blog.

Which SQL Server Version Works Best with SQL Performance Tuning?

Knowing the versions that support this task is extremely important because it will give you the ability to improve the SQL Server database and SQL performance.

To that effect, we will discuss the SQL Server 2016, 2017, and 2019 versions here.

SQL Server 2016

This version was chosen by a lot of independent software vendors or ISVs for one reason – 2016’s Service Pack 1 edition came with Enterprise features in Standard mode. These helped create a single application version that worked simultaneously for both Standard as well as Enterprise clients.

Advantages of Choosing this Version:

  • It is easy to find support material online as this version is quite popular and numerous database professionals are well-versed with this version’s tools.
  • Standard Edition users may find this version appealing since it supports 128GB RAM and additional space for internal functions such as query plans.
  • Support for this version ends after 2026 – longer than the older versions (2012/2014).
  • Newer applications that have additional compliance requirements will benefit from features in this version such as Always Encrypted, temporal tables, and Dynamic Data Masking. These will make it somewhat easier to protect and monitor sensitive information.
  • You can have both row store and column store indexes in this version, unlike the earlier ones that only had row store indexes.
  • If you need query plan monitoring to help with SQL performance tuning, you can use the Query Store’s features provided in SQL Server 2016 for this purpose.

SQL Server 2017

Being a newer release, it is one of the most regularly updated versions with patches coming in almost every other month. These patches are important because they resolve significant problems. It also comes with a minimum commit replica configuration to ensure commits are accepted by several replicas.

Advantages of Choosing this Version:

  • The upgrades are easier to get from this version onward due to a Distributed Availability Group that contains multiple SQL Server versions in it. Before this, we had AG version upgrades that were not as convenient, leading most users to construct a new cluster and migrate to it rather than opt for an upgrade.
  • This version contains batch mode execution plans, which gives those who require high-performance column store statements an advantage.
  • If you must run your SQL Server on Linux, you may consider SQL Server 2017 as several bugs have been resolved in the Cumulative Updates.
  • It’s a newer version so support will last longer than that of its predecessor.

SQL Server 2019

Released on November 4, 2019, this version is the latest in the SQL Server series. Naturally, it comes with the longest support lifespan, i.e. it will be supported until 2030. This version also receives regular patch updates to fix many significant issues in the form of Cumulative Updates.

Changes and Features in this Version:

  • Patch contents aren’t documented anymore. Moreover, you are likely to receive updates with undocumented new features – something to consider in case you require it for mission-critical production environments.
  • There is a bit of a learning curve thanks to some cutting-edge features in this version, so be prepared to perform some experimentation as you learn.
  • Some of the best performance features are included in the 2019 compatibility mode. However, you will have to keep a close eye on all SQL Server databases and SQL queries – even the ones running fast at present – as these will alter your current execution plans. In other words, you will have to test both slow and fast queries to make sure the slow ones speed up and the fast ones don’t fall behind in performance.
  • Table variables have gotten better in this version along with user-defined functions.
  • Additional features to watch out for including Big Data Clusters, Java support, and high container availability, so you may want to explore this version if you’re looking for perks like these in the SQL Server you want.

In Conclusion

At this point, SQL Server 2017 might seem like the best version to go with, thanks to a balance of features, stability, and support lifespan. Furthermore, you’ll receive plenty of help with SQL performance tuning – a lifesaver for overworked professionals who may not have the time or resources to upgrade every server every year.

Oracle Database and SQL: The Pros & Cons of Bind Variables

SQL Server database and SQL

Bind Variables are typically considered as one of the major aspects of enhanced SQL query performance. According to Oracle documentation, they serve as a placeholder in a SQL query, getting replaced by a particular value that helps in statement execution.

The use of these variables enables users to create statements that can receive time-running parameters or inputs. One may think of bind variables as “value” given to the SQL query that acts as any function in programming languages. Here, we will talk more about them as well as their advantages and disadvantages in Oracle database and SQL.

Bind Variables: Examples of Their Uses

Consider the following statements in SQL –

Select * from Staff where S_No = 1 ;

Select * from Staff where S_No = :a ;

In the first query, a proper value (1) is applied to operate the query, whereas, in the next query, we have used a bind variable (:a) to operate the statement. This bind variable is given to Oracle when the query is run.

Defining a bind variable in the SQL statements in the place of literal values ensures that a single Parent Cursor is utilized by Oracle for the query. This helps improve database performance because Oracle searches for precise text matches for the query to check whether it already exists in the shared pool. Using a bind variable rather than a literal value saves an expensive hard parse for each run of that query.

Bind variables prove especially useful in OLTP-type environments because their use facilitates soft parsing. In other words, it takes less processing time to re-generate execution plan.

How Bind Variables Help Improve Database Performance

Given below are some advantages of using bind variables:

  1. Optimal Use of Shared Pool – The Shared Pool in Oracle Database needs to hold a single query instead of possibly numerous queries, thanks to bind variables.
  2. Improved Performance Due to Zero Hard Parsing – There is no need for hard parsing because SQL queries only diverge in terms of values.
  3. Decreased “library cache” Latch Contention – Since library cache latch contention is needed during a hard parse, its requirement reduces when bind variables are used.

Shortcomings of Bind Variables

The disadvantages of using bind variables are few. Although bind variables prove excellent if you want to improve Oracle database performance, there are instances where their use can negatively impact results:

  • They can decrease the flow of information needed to compute the best access path for CBO (Cost Based Optimizer). The CBO, in turn, may fail to identify the correct selectivity and create insufficient bad execution plans, opting for a complete table scan instead of using indexes.
  • Sometimes, the CBO requires the literal value to be used by SQL in order to build a robust execution plan. With bind variables, the literal value gets “hidden”, so the CBO is likely to create a subpar plan.

To overcome this issue, Oracle has tried to provide further assistance to the CBO by enabling it to take a look at the bind variable’s value during execution plan creation, which is known as “Bind Variable Peeking”.

Conclusion

The use of bind variables is extremely useful in Oracle database performance, especially when it comes to OLTP environments. However, as a user, you need to be careful while using bind variables. . It is recommended to use bind variables for short runtime SQL, but use literals for long time SQL statements to more information to CBO to generate good query plans.

SQL Query Optimization Tool Online: Top Characteristics

MySQL database and SQL

Data is one of the most important resources in an organization and SQL is the most popular method to store and manipulate it. Therefore, the widely-used Structured Query Language is supported by almost every modern RDBMS around the world.

This is also why database servers are often known as SQL Servers, where the language establishes the manner in which the statements will be formed to fetch the required data. Since modern databases can get rather bulky due to a large number of joined tables, the SQL queries needed to access the right information present inside can get quite complicated as well.

This decreases performance – and SQL query optimization is needed to maintain desired results. Although this can be done manually, there is more than one SQL query optimization tool online available for assistance. Here, we will discuss what SQL query optimization is about, followed by the major characteristics of optimizing tools.

What Query Optimization Means in MySQL Database and SQL

Let’s start with the what and why of SQL query optimization. In basic terms, it is the process of assessing SQL statements and identifying the most productive method to complete a certain task.

Generally, it involves a trial-and-error technique where different statements are tested to compare their performance. The query that exhibits the best performance while still fetching accurate data is then selected.

Although database management systems may already have query optimizers, you can opt for a third-party SQL query optimization tool online as they often provide faster and better results. The average query optimizer produces one or more query plans for each statement to help run the query.

The execution time of every plan is measured and considered as the performance parameter to pick the most efficient one that can run the query in the least time with the same results.

MySQL Database and SQL Query Optimisation: An Example

Let us consider a simple example related to this: suppose a user has to run a statement to fetch around half the information present in a table at a time when the server is already occupied with several connections at once.

This is where the query optimization tool can pick out the optimal query plan that requires minimal resources to fulfill the query. This will also take up fewer server resources. In case the user has to use the same statement at a less busy time, the query optimizer is designed to verify the availability of resources and proceed with loading the complete table in memory instead of using table indexes.

Major Characteristics of a SQL Query Optimization Tool Online

Here’s a look at the three major characteristics that are typically built into a MySQL database and SQL query tuning tool:

Compatibility with Database Engine

A majority of tools are created to support the biggest database engines out there, including Oracle, Microsoft SQL, MySQL, MariaDB, and PostgreSQL. However, some tools may be designed to support a single database management system or to be compatible with an even wider range of engines.

Essential SQL Tuning

One of the core features of every SQL query optimization tool online is the ability to provide basic SQL tuning. It implies rewriting SQL queries to boost their performance, which is done by measuring the time it takes for different versions of the statement to be executed. After this, the version that gives the best results is selected.

Compatibility with Cloud-based Databases

Certain tools come with a feature that allows them to assess and improve the performance of cloud-based database management systems. The best examples of cloud-based databases are AWS RDS and Microsoft SQL Azure. However, not every tool is guaranteed to provide this support, so check whether the one you’re considering does before you make your selection. Also, note that a majority of tools that are compatible with cloud-based MySQL databases and SQL will also work with those present on the premises.

5 Reasons Why a Hardware Upgrade can Worsen Performance

SQL Server query optimizer tool

After gaining approval to switch to new hardware (at last) and a newer SQL Server version, you start to make preparations. But what will you do if the performance worsens after you finally do the migration?

Hardware upgrades are often preferred over MySQL SQL performance tuning but the transition may not necessarily take place smoothly. In this post, we will consider five of the most common reasons why a hardware upgrade may actually worsen performance, and how to identify these reasons.

Hardware Upgrade Over MySQL SQL Performance Tuning: 5 Things to Check

Using a SQL Server query optimizer tool might not be the best bet here since the hardware has been changed. In such cases, consider the five most common ways given below to troubleshoot this problem:

Check a Few Sys.configurations Settings

The default setting for “max degree of parallelism” is zero in SQL Server. This means all the cores get used by queries that go parallel, so your workload on the new instance may be facing tasks struggling for CPU usage due to this setting.

You can find out if this is the case by comparing all the configurations in sys.configurations between instances and searching for anything that stands out. Some users might accidentally set the lowest memory value for a query.

Investigate for Bottlenecks in Hardware Settings

Certain unexpected situations can lead to a few problems that might not get detected until after hardware upgrading or migration. For instance, the server might not be receiving sufficient power, which can affect CPU operation as well. They become less capable and therefore, show greater utilization when checked in Windows Task Manager.

Identification can be done in two ways:

  1. Keep an eye on the Windows System log. You may find messages related to improperly plugged power sources.
  2. Try running a free tool to gauge the clock speed of the processors and whether all of them are operational. Different from a SQL Server query optimizer tool, you can find one online nevertheless.
Check if Your Processors are on Power Saving Mode

It might not be the sole cause behind greater CPU usage but you can expect it to be one of the elements contributing to the issue, aside from a need for MySQL SQL performance tuning. Fortunately, this is something you can resolve rather quickly, so it’s certainly worth a glance.

This setting can be checked in the BIOS – disable power savings in case it is enabled. However, you may have to confirm the change with the help of a server management tool such as HP System Insight Manager and a planned outage that will give you time to make the desired change in the BIOS and reboot the server.

Check the New SQL Server Version for Stack Dumps

A stack dump, also known as a “15-second error” is responsible for leaving the storage unresponsive for fifteen seconds, followed by increased load.

To check for a stack dump, you will have to open the SQL Server error log and look for errors in the span of some days. You can filter using the terms “15 seconds” or “stack dump” to locate the culprit.

Inspect Factors Outside SQL Server for CPU Usage

Although you may have already looked into this, experts recommend double-checking to ensure the database professional doesn’t miss anything. You may be surprised to see a user testing with the server or using a SQL Server query optimizer tool. They may neglect to inform you – or forget to revert to the original settings. Sometimes, users may forget about previously running tasks while a new instance goes live.

To find out what went wrong, open the Windows Task Manager to take a look at all the processes that are utilizing memory and CPU. There shouldn’t be any agent tasks or scheduled jobs that were absent on the previous server.

Using Free SQL Tools for Windows to Monitor Your Database

MySQL database and SQL

There are several reasons why SQL monitoring is a must, especially for organizational databases. However, you need to understand those reasons to know the importance of regular database maintenance.

SQL tools have a prominent role to play in this, and while some of them may cost money, there are several free SQL tools for Windows to enable successful database monitoring. In this blog, we’ll go through some functions and perks of using such tools.

Benefits and Features of Using Free Tools for Windows

Consider the following advantages of such tools in the management of your database:

  1. Ease of Operation

Monitoring a database involves several complicated tasks that can fill your schedule and keep you from performing other necessary activities. As a database professional, you already have plenty to do, so there may not always be time or resources to get it all done on a regular basis. 

In such cases, you can choose specially designed software to automate a majority of these tasks. Such tools also handle smaller issues on their own (based on the settings you choose). This leaves you more time for the rest while giving you updates at the frequency and priority of your choice. Of course, you will have to figure out an estimate of your organization’s requirements and affordability while considering which tool to use to monitor SQL.

  1. Easier to fix issues

Regardless of how smooth and streamlined a database seems, it is bound to run into a few problems sooner than you think. This is why you not only need to know what kind of problem it is, but you also have to find the cause behind such issues – which can prove to be a challenge.

Monitoring using paid or free SQL tools for Windows means you get better access to information regarding the server’s present condition. This simplifies the process of uncovering faulty processes that are leading to deadlocks and other issues without much effort. You can find what’s going wrong on your own as well. However, these tools make the process much more convenient, giving you more time to troubleshoot a greater number and variety of problems quickly.

  1. Use as per Your Unique Requirements

Although SQL monitoring tools offer a one-size-fits-all solution to users, a majority of DBAs prefer the option to customize their settings and receive alerts according to their preferences. It is an incredible advantage of using such tools because it allows users to adjust their functions as per their specific requirements, making them useful for years to come because your needs can change as time passes.

  1. Remote surveillance is simplified

Optimization in SQL becomes more convenient once users have the ability to keep an eye on database performance and make changes when necessary, regardless of their location. Monitoring tools grant this ability to their users, thanks to their browser-based interface.

Aside from providing remote tasking to professional Database Administrators, numerous tools also enable users to adjust their dashboards as they like for even greater customization. Ultimately, it is up to you to select the right monitoring tools, whether they are free SQL tools for Windows or paid ones for the platform you require. All you need to do is acquire the knowledge and skills needed to make the most of such tools and your database.

Downloaded Free SQL Server? Maintain its Health, Too

Ensuring the optimal health of a database is vital to maintain ongoing operations. As a Database Administrator, this is one of the main tasks associated with database performance.

Although it may sound challenging given the complex operations involved, there are simpler ways to achieve this without expending significant time and energy. Here, we’ll briefly explain six such tips to keep an eye on database health, even if you did download free SQL server

6 Ways to Maintain the Health of Your SQL Database

If you want to know how to keep your database functioning optimally, here are a few tips:

  1. Try not to decrease the size of the database too often.

There are numerous guides and tutorials present online to help you shrink a SQL database. Even if it may be useful for certain reasons, one of its major downsides includes greater fragmentation – this, in turn, has a substantial impact on the database’s overall performance. It is because repeatedly doing so actually decreases space instead of giving you extra space, due to defragmentation. 

  1. Build a habit of taking frequent offsite backups

This point is extremely essential and cannot be stressed enough! The more frequent your offsite backups would be, the better prepared your organization will be in the event of data loss due to possible situations such as hardware damage and software crashes.

All you will have to do is perform a SQL fix operation or use a database copy in case a user commits a manual error, like forgetting the password, for example.

  1. Keep an eye on database consistency – on a regular basis

Database corruption is already a big issue in itself. It doesn’t necessarily happen when you download free SQL server but it does create problems. That’s because users receive incorrect results or no data at all, even after inserting the right statements. However, it spells greater trouble because it can lead to extreme consequences such as a total breakdown of the SQL instance.

You can easily prevent such mishaps from occurring with the help of certain SQL queries. In fact, you don’t have to run them manually either; you can schedule them to run automatically whenever it is most convenient.

  1. Check your SQL backups periodically

Creating backups of your database is part of the solution: you also have to frequently ensure the backups are operating as desired. They have to be readable and available for when they will be required. Some situations can lead to a point where your incremental backup fails due to server breakdown. In such cases, you can fall back on the backup that was last available.

  1. Monitor the health of your server, too

Aside from monitoring the health of the database, it is also important to check the health of your server. What if your database is working perfectly but something goes wrong with the server? You need both to maintain operations, which is why you must also conduct routine server maintenance sessions. Set yourself consistent reminders to do so regularly.

  1. Keep tabs on deadlocks to prevent them from affecting database performance

Deadlocks can be inevitable in situations where several connections are trying to access the same information at the same time. The victims end up being the users whose requests were blocked or denied by the server. Deadlocks can be prevented with the help of application codes.
