Solutions to SQL Software Performance Issues: SQL refers to Structured Query Language used to update databases and manage queries. In other words, it is a standard database language. All relational database systems, for instance, Oracle, MS Access, and Sybase use this system software.
Solutions to SQL Software Performance Issues
Many companies use this server to manage database because it does not require coding. Further, it performs well in all types of devices from desktops to some of the mobile phones.
Although it has certain benefits and many companies have been using it, SQL faces some performance issues while executing queries. Apart from this, you may have been facing several other issues such as slow processing, poor queries and CPU issues. It is important that you know the ways to deal with these performance issues. This blog discusses most common performance issues and their solutions.
Slow Processing Of Queries
If queries take longer time than usual, the issue can be due to resource orientation from locking. This issue normally emerges when you add new processes to your system or when the load goes up. In both the situation, you will have a problem of slow processing of queries.
You can use SQL server profiler to troubleshoot this problem. It is a separate application through which you can know whether the query is running on the server in real time or not. You can also use extended events, a feature built into the SQL.
Once you have identified the slow processing query, you need to figure out the cause. If it happens because the query is blocked, you have to identify what was blocking. Do not forget to look over the execution plan to make sure that this stage does not consist of an error.
Receiving The Error That Your System Is In Deadlock
You can also receive notification that reads you are in deadlock state. The SQL system comes in the deadlock state when two or more queries lock resources and fail to get completed. You can fix this issue with display deadlocks in mobile consoles.
The mobile console of SQL will help you diagnose the problem and fix SQL server performance issues immediately. You will have a resource view. It contains five filters and one of them is session filter. It presents key metrics. Look at the value of these metrics and then identify the performance patterns in activities. This will give you a view about performance indicators. This will also give you a detail of blocked sessions, lead blockers and total number of deadlocks.
When this issue gets resolved, the server log will report the situation. It is the best place to know whether the problem has been solved or not. If this way does not work to fix this problem, another way to solve the issue is turning on the trace flag. This will give you complete information in your log.
Having database out of space is very common problem. You are likely to receive this message frequently. This issue generally arises because of two reasons. First off, the physical drive stores the database and the second reason is transaction log has run out of space. You can resolve this issue by removing files that are growing rapidly.
The transaction log has generally a maximum file size. Increase the limit so that database can be operated smoothly. Make sure that temped is not full. This is also one of the causes of having space errors. You can empty it out by restating the SQL server. This will recreate tempdb from scratch. Try to increase its size also to avoid any trouble in the future.
The Bottom Line
Aforementioned are the common problems that you can face with SQL servers. Most of the businesses are using SQL servers because of its benefits. You can communicate with the database and receive answers to the complex questions within seconds. This is licensed software, which means you have to pay for it.
