Mirroring Technology Many solutions provide the commercial Disk Mirroring Technology to achieve high scalability or disaster recovery through the shared disk cluster solution. However, these solutions do not provide you with full protection when the disk is damaged. If the source disk is damaged, the damaged data is also transmitted to the target. In addition, this solution does not provide the instantaneous failover function, which is critical to 24x7 businesses. DB2 High Availability Disaster

OLAP (On-line Analytical Processing) online analytical processing, also known as transaction-oriented processing, is characterized by the fact that the user data received by the foreground can be transferred immediately to the computing center for processing and the processing results are given in a very short period of time. is one of the ways to quickly respond to user actions.OLTP (on-line Transaction processing) online transaction processing, which enables analysts to quickly, consistently a

OLTP performance adjustment and optimization-conclusion According to the waterfall model of the software life cycle, the performance of an application has been qualitative in its design stage. If you think of optimization only after the application development is complete, you can only cure the problem. In the case of serious performance problems, you even need to re-launch the entire software. When a software system has been launched for operation an

, the heap scan also carries out concurrent scans.TSQL Enhancements for memory-optimized tablesMany TSQL statements are not available in SQL Server 2014 and are now available on 2016: Supports UNIQUE constraints and indexes Support for foreign keys between memory-optimized tables A foreign key can only refer to a primary key and cannot be created with a unique Support for CHECK constraints Non-unique indexes support NULL in key Support for triggers

SQL Server 2014 introduces a memory database, which is a very good function. Data can be directly stored in the memory, which can be operated directly on the memory, greatly improving the performance. Today, I think of a problem. What happens if

. Database performance (OLTP benchmark) Sysbench's database OLTP tests support MySQL, PostgreSQL, and Oracle, which are currently used primarily for Linux operating systems, and open source communities have migrated sysbench to Windows and supported the benchmark for SQL Server.
