A few years ago, vendors said they could provide a variety of security features (Including Intrusion Prevention System functions and application control) on a device. Then we saw the next generation of firewalls emerging.In the current market research on the next generation firewall (NGFW), experts said that not every NGFW provides the functions that every enterprise wants, and, in some cases, too many feat

With the gradual rise of the network activity, the threat that the enterprise faces is growing exponentially. As an enterprise IT manager, how should choose Next Generation firewall. Nearly two-thirds of network traffic is web-based applications, with new security threats and network bandwidth usage increasing. Today's network traffic requires proper control of the next-generation firewall (NGFW). According to Gartner,

, providing security support for data communication. Network Address translation: Network address translation (NAT) is a way to map an IP address domain to another IP address domain technology to provide a transparent route for a terminal host. NAT includes static network address translation, dynamic network address translation, network address and port conversion, dynamic network address and port conversion, port mapping and so on. NAT is often used to convert private address domains to public

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 an

commit command, the system assigns the current SCN to the transaction. The information is reflected in the redo buffer and immediately updated to the redo log file.Offline SCNWhen we execute SQL> alter tablespace... When the offline normal command is run, a checkpoint is triggered to write the dirty buffer in the memory to the disk file. After the checkpoint is completed, the data file header updates the

modification during database recovery. Control files are generally used to store the status of the physical structure of a database. Some status information in the control file is used to guide Oracle during instance recovery and media recovery. Ii. Online logs Each instance of an Oracle database has an associated online log. An online log consists of multiple online log files. The online log file is filled with log items. The data recorded in the log items is used to reconstruct all modificati
