sql server consolidation tactics and best practices

1. Introduction As companies use more and more applications to manage business processes, provide new services, and gain an observation of business performance, the number of application servers and data storage servers required to support these applications is significantly increased. In many companies, the cost of hardware and the cost of deploying and maintaining multiple servers within the company are major financial and logistical budgets. At the same time, improvements in hardware and so

Label:In the mature leading enterprise database system, parallel query can be said to be a big weapon, in some scenarios he can significantly improve the corresponding time of the query, improve the user experience. such as SQL Server, Oracle, etc., MySQL is not yet implemented, PostgreSQL has implemented parallel scanning in 2015, believing they are also moving toward a more robust enterprise-class databas

time = 39 Ms. We can see that no performance improvement is achieved when indexes are set up, and more time is consumed, so we can continue to adjust the indexes. Then we delete all non-clustered indexes and delete the primary key, so that all indexes are deleted.Create a composite index data1 and dtat, and add the primary key: Create clustered index [c_data=dtat] on [DBO].

SQL Server backup and recovery practices I started to back up and restore the database because a project was completed right away. I checked several methods to achieve this. My goal is to back up the database on the server, so I found several methods for implementation, which are roughly divided: 1: Back up data us

index is deleted. Doing so causes an unnecessary rebuild of the nonclustered index. The conversion of a table from a heap table to a clustered index table always results in the rebuilding of a nonclustered index, because the content of a nonclustered indexed bookmark changes from the row number to the key of the clustered index. Do Plan Your Index defragmenting and rebuilding Based upon Usage If an index is frequently scanned, the external fragmentation of the index is important, which can have
