What is the most common use of a database server?
Database servers are used to store and manage databases that are stored on the server and to provide data access for authorized users. This type of server keeps the data in a central location that can be regularly backed up. It also allows users and applications to centrally access the data across the network.
Which database server is best?
MySQL. In 1995, two Software Engineers, Michael Widenius and David Axmark, created the Open Source Relational Database Management System (RDBMS) MySQL.
What to look for in resource usage in MSSQL?
The main information we want to check is to see if the CPU is constantly running above 90%. This means the system may not be able to keep up with resource demands, which will cause the system to slow down. This gives us the total amount of memory on the system, what is currently being used, and the available remaining memory.
When to look for performance issues in a database?
If the database is transactional, look for the queries that are run very frequently (put the profiler output into a database table and count by query) and look at tuning them. If performance is still an issue, then you need to look at new hardware (bigger server, faster disk, more memory, faster network) or to split the databases across servers.
How does SQL Server know when it needs more memory?
By default, SQL Server changes its memory requirements dynamically, on the basis of available system resources. If SQL Server needs more memory, it queries the operating system to determine whether free physical memory is available and uses the available memory.
Where do I find Resource Monitor in MSSQL?
To start the Resource Monitor, click the Start menu and type resource, then select Resource Monitor. The Resource monitor provides us with more granular detail, broken down by the four key resources we mentioned earlier: CPU, Memory, Disk, and Network.
