checkpoint tracker

A checkpoint is a database event that writes the modified data from the cache to the disk and updates the control file and the data file.Checkpoints fall into three categories:1) Local checkpoint: A single instance performs a checkpoint operation for all data files in the database, and all dirty buffers belonging to this instance are written to the data file.Trig

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

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

Calculate the IMEI checkpoint and the IMEI checkpoint Calculate the IMEI checkpoint The International Mobile device Identification Number (IMEI: International Mobile Equipment Identification Number) is a unique identifier of a Mobile device. It is attached to the logo on the back of the Mobile phone and stored in the Mobile device, it can be used to monitor stole

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

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

Tracker server is the coordinator of the Fastdfs file system, and its main role is load balancing and scheduling. Tracker server records information such as grouping and storage server status in memory,File index information is not logged, and the amount of memory consumed is low. In addition, when the client (app) and storage server access Tracker server,

When studying the implementation of the GEF palette, I found a SWT control that I have never used before, probably because I rarelyProgramTo handle the mouse movement and other events. This good thing is tracker. I very much hope to call it a Shadow Warrior, because tracker often works with mouse clicks and movement events to dynamically display the changes in the position and size of the operated component
