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

Juniper: For UTM, it's all about security. If the customer is concerned about performance, it certainly has an impact. Large UTM are not all enabled. Through the experiment, the test of the contract device is still good performance. Lenovo Network Royal: At this stage, we recommend that users choose UTM according to their own business situation, some of the feat

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

Nearly a period of time, many traditional UTM manufacturers frequently released high-end products-first SonicWALL release 4G products, after the industry's eldest Fortinet thrown 26G of the top UTM. Some analysts pointed out that the emergence of high-performance UTM is not a long time, this is a long-term security manufacturers brewing. Because with the performa

Unified threat Management (Unified Threat Management), in September 2004, IDC first proposed the concept of "unified threat Management", which is to put antivirus, intrusion detection and firewall security devices into unified threat management (Unified Threat Management, Short UTM) New category. IDC integrates concepts such as antivirus, firewall and intrusion detection into a new category called Unified Threat Management, which has attracted widespr

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

The author understands that the UTM definition includes at least three elements as follows: 1. Threats to face UTM is deployed at the network boundary location, targeting 2-7-tier threats of all kinds. According to the consequences of threat destruction, the threat of network boundary can be divided into three categories: the threat of destroying the network itself and the application system, the threat o

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

Usually UTM devices include firewalls, antivirus gateways, IDP, anti-spam, access control, VPN, intranet monitoring, and many other functions. Not every function is what we need, the user should choose which function module is necessary. Of course, in the case of similar prices, the more functions the better, but also to consider whether performance support. At present, some manufacturers in order to solve the problem of internet abuse, is also the mo

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
