Type: DLP-450S Name: 450 s Series columns: Product Description: 1. the patented Serial ATA interface (dual Interface) is fully compatible with the efficient Serial ATA interface hard disk. 2. The line design is rigorous and mature, providing reliability. 3. Stable and powerful power output, supporting disk arrays of multiple hard disks. 4. The Harmonic Suppression Function can effectively improve the power supply quality and load cap

The redolog switch has a full checkpoint or incremental checkpoint. There is a lot of information on the Internet, but it is not clear whether the full checkpoint or incremental checkpoint occurs when a log switch occurs. Some people say it is a full checkpoint or an increme

1. Overview In the use of DLP as a light source for surface exposure 3D Printing system, we often encounter the projector or light machine projection of light, deformation, fuzzy situation. These situations can lead to the following problems: Print model surface has a pixel texture, not enough smooth model local exposure distribution uneven, thick and thin, in the printing of very fine parts especially when the light source trapezoidal deformation, r

Explanation of the Checkpoint:For performance reasons, the database engine modifies the database pages in memory (buffer cache), but does not write these pages to disk after each change. Instead, the database engine periodically issues checkpoint commands for each database. Checkpoints writes modified pages in the current memory (called dirty pages) and transaction log information from memory to disk and logs information about the transaction log. The

Every time I talk about SQL Server, I'll start by talking about what happens inside SQL Server when we execute the query. Executing a SELECT statement is straightforward, but executing DML statements is more complex because SQL Server modifies the related pages in memory and records the entire transaction in the transaction log.After describing these specific steps, I always ask the same question: Does SQL Server crash when we have an uncommitted transaction that happens to have a

Most relational databases have the advantage of performance by "not forcing modifications to the block at the time of submission" but rather "writing log files in the form of a record (in redo log)" when committing. That is, when a user commits a transaction, the write data file is "asynchronous" and the Write log file is "synchronous".This can cause the database instance to crash when the modified data in the Db_buffer in memory may not be written to the data block. When the database is reopene

There's a lot of information on the web that doesn't make it clear whether the log switch is a full checkpoint or an incremental checkpoint. Some say it's a complete checkpoint, and some say it's an increase. Quantity Check point. In fact, if you have a deep understanding of the difference between a full checkpoint an

Implementation of database transactions-fault recovery (2) (undo log checkpoint) bitsCN.com In the previous article on implementation of database transactions (I) fault recovery (undo log), we introduced the application of undolog in data recovery. This article will continue to introduce undolog, however, we will introduce how to use undolog to recover data. At the end of the previous chapter, we left a problem: in the model described in the previous
