record when writing or revising a file. Therefore, when data inconsistency occurs, you can examine the log record block directly, and you can quickly identify the problem. Linux EXT3 is a file system that supports logging capabilities. It has also been said that since the disk is much slower than memory, Linux does not immediately update the modified data in memory to disk after modifying the data in memory . instead of using asynchronous processing, the system will not periodically write th

swap by using the fsck command to divide a partition into a swap, and then use the MKSWAP command to format the partition as swap, and then use the Swapon The device file name "to start the swap device. can use Free This memory view command to see if swap is loaded correctly. In addition to building a partition into swap, you can use a large file to construct the swap, which is similar. you can also use Swapoff to release swap files when you use a file to build swap.

method is recommended, mainly low costThere are several advantages:1, compared with the physical image of such technology, this scheme is more economical. Backup service hardware requirements are not high, as long as the hard disk is large enough.2. Although SQL Server provides several backup verification mechanisms, the only way to ensure full reliability of backup is to actually recover it.3, early recovery backup, so that when a real disaster occurs, only need to restore the last log backup.

actions are automatically run if the free space is greater than 25%,sql server. So this feature prevents the data from requesting too much space and not using it. For a system with a very tight disk space, this setting is undoubtedly helpful. But from the database's own health and performance considerations, this setting is not recommended for multiple use. This is because:1. SQL Server will grow automatically only when the space is exhausted. If there is no reason to look for growth, it will f

has not been shipped becomes a shipment, it is actually the status of the update order . All orders that have not been shipped and all orders that have been shipped are actually retrieved for all orders of different states . In the DAO layer, the parameters we need are often single , either specific objects or IDs ... However, in the service layer, the parameters we want are connected to the entity class . Example 1: When generating an order, theDAO layer simply needs the order obj

are most appropriate for the database business requirements. This figure shows 4 filegroups, one at a time, for each filegroup. Their backup order (a, C, B, a) reflects the business requirements of the database.Under the full recovery model, restoring a filegroup backup requires not only restoring the filegroup backup itself, but also restoring all log backups from the last full database backup to the target point in time of recovery. To ensure that the file remains consistent with the rest of
