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

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

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

OVirt v3.4 began to support hosted Engine. What is hosted engine? Very simply, the previous management node was deployed on a physical machine, and now we deploy the management node to a virtual machine, and the virtual machine runs on the compute nodes in the Ovirt virtualized environment. Previously, the management node was deployed, the compute nodes were deployed, and the compute nodes were registered to the management node, and the virtual machines could be run on the compute nodes through

VSAN 6.1 has been released for two or three months, with 2 notable new features, one of which is support for stretched Cluster, which means that your Vsan cluster can now be located in a physical location, deployed across data centers, and a 2-node Vsan.We know that the original Vsan needs at least 3 nodes, why? Since the default FTT is 1, each data disk requires at least 3 components, 1 copies of data, 1 copies of the data, the 3rd is the witness component (Witness component), the equivalent of
