system gives ShipCountry the hash aggregation pushed, and CustomerID pushes the stream aggregation. This means that the SQL Server system dynamically chooses the appropriate aggregation method based on the query's situation. So when we do SQL optimization, we can't just optimize it based on SQL statements, we have to

behavior associated with memory consumption and to improve dynamic memory allocation in order to ensure that each component is in efficient use.Memory Broker can schedule the allocation of allocations between various components that use caching, such as buffer Pool, query Executor, query Optimizer, and so on. Through the monitoring of memory requirements and consumption, through the dynamic allocation algorithm with feedback and improvement mechanism

Transaction Log backup is applied to each secondary database. The optional third server instance (called the "monitoring shi

Spid 55 is waiting. Here the process is blocked, causing a deadlock. 4. SQL Server checks that the two processes (the first and second sessions) have deadlocks, and adds the processes that consume less resources to the

the advantage is that the availability replica is a standalone instance, so the database copy resides on the local disk where the instance node is running, and if the availability replica is a clustered instance, the database copy is stored on the shared disk.An availability group is a cluster resource from a Windows cluster perspective, where all databases fail over between nodes as a whole, and of course this excludes system databases, which cannot be added to the High Availability group.Beca

Label:Original: SQL Server DBA work detailsIn a Microsoft SQL Server 2008 system, the database administrator, or DBA, is the most important role in the administration. The DBA's goal is to ensure that the Microsoft SQL Server 2008

use of inappropriate transaction isolation level, will lead to excessive blocking.These reasons should not be analyzed separately, and inefficient execution plans can exacerbate the use of system resources and cause overall performance degradation of workloads. Therefore, if a large table loses a valid index, or the query optimizer does not choose to use the index, the query will be very slow. These conditions also put a lot of pressure on the I/O subsystem's read operations, because I had to r

, you do feel that you know too little about SQL Server before. Ideally, you should also place the tempdb database, the content database, the usage database, the search database, and the SQL Server transaction log on a separate physical hard disk.When setting the data priority on a faster disk, use the following rating
