There is a dirty list (that is, write list) Statement in Oracle, but there is also a checkpoint queue. These two items are often confusing. Are they the same thing? What is the relationship between them? Before proceeding, let's take a look at the description of a master. Http://www.ixora.com.au/q+a/0103/07160329.htm That information is not quite right. it is more accurate to say that there are 10 lists, because there are 5 types of buffers and there

We know that InnoDB uses the write Ahead log policy to prevent the loss of downtime data, that is, when a transaction commits, the redo log is written, and then the memory data page is modified, resulting in dirty pages. Now that you have redo logs to ensure data persistence, you can also fetch data directly from the buffer pool page when querying, why refresh the dirty pages to disk? If the redo log can grow infinitely and the buffer pool is large enough to cache all the data, it is not necessa

The IPS VLAN Group is a IPS6.0 feature, where VLAN group blending mode requires a VLAN tag when configuring mirroring, which is not the default in GNS, and VLAN group online mode is an overlay of online mode and VLAN group. Configure the online interface pair first, then configure VLAN Group on the online interface pair to tell the IPs which VLANs are running on it, and support to send different VLAN data t

The checkpoint, in fact, is a record of past history, which can be thought of as log. But here it is simplified. For example, I am now a text. There are piles of links in the text. My task now is to download the contents of those addresses. In addition, because of network problems or problems with the website, Each download may not be very successful. There is a possibility of a broken chain or socket exception error. But no matter what kind of mistak

Checkpoint, also known as a checkpoint, means that all the dirty data is written back to the disk in Oracle. The database achieves consistency and data integrity. Oracle performs transaction rollback with the latest checkpoint as the reference point during media recovery. In PostgreSQL, checkpoint plays the same role:

Cost-effective overseas VPS brand Vultr VPS announces a new feature called "Reserved IPs", as the name implies to help you keep the server IP address for later use.This requirement is because users often create new, delete a VPS server, the default is assigned to the random server IP address. If you are in the company of a certain size of server cluster, you prefer to keep the original IP address unchanged, saving time to modify the configuration.Usin
