This is the third article from 0 to build SQL Server AlwaysOn, this article really started to build AlwaysOn, the first two is to build AlwaysOn to prepareOperation Steps:1. Install SQL server2012 ( Note: Be sure to install. NET fromwork 3.5 and log in and install with each node's local administrator account, do not use the Domain Administrator account )2. Select

the SQL window and then reopen for recovery operations, If you also hint that the error you are using can stop the SQL service and then restart it, as the above other errors can generally be changed according to the wrong content to restore Third, shrinking the database In general, the contraction of the SQL database does not greatly reduce the size of the dat

and their possible impacts: The read/write throughput and disk space capacity of the I/O subsystem. You must be able to meet peak workload requirements and provide sufficient space before you have to purchase more capacity for the increased data volume. You can determine the I/O bottleneck and move the data and/or log files to other parts of the I/O subsystem to balance the load more evenly. I/O Sub-system RAID-level redundancy and the ability to perform operations such as splitting image backu

connection pool to maintain the web site. Therefore, as more connections are blocked, the Web site creates more connections, and these connections are blocked, this cycle will continue. The log write operation will be completed in about 45 seconds, but hundreds of connections have accumulated so far, leading to blocking problems, it takes several minutes for SQL Server and applications to be restored. When

minutes, etc.), in this way, the primary server to the backup server is usually asynchronous update, so the primary server and backup server data are not guaranteed to be consistent. In addition, the scheme usually does not implement automatic fault monitoring and failover.
