By 2027, the global real private cloud (true private CLOUD,TPC) market will reach $262.4 billion, with an annual CAGR of 29.2%, while the TPC market will grow faster than the public cloud IaaS market, while the locally deployed TPC market will be 32.5% Growth of $176 billion. This is the latest forecast by Wikibon, a U.S. market research firm, released in August 2018. In 2017, the global TPC market grew by 55% to $20.3 billion, while the TPC market was 40% of public cloud IaaS and grew at a rate

Basic laravel tutorial-file system/cloud storage overview Laravel provides a powerful file system abstraction, thanks to the Flyststem PHP package developed by Frank de Jonge. Laravel's file system provides support for some storage drivers, including local file systems, Amazon S3, and Rackspace cloud storage. What's more, it can switch these storage systems through the storage configuration option, because laravel provides a unified API interface for

. This directory is called the archive directory, and the copied file is called the archive redo log. You can perform catastrophic recovery only when the database is running in archive mode. 1. the difference between the archive log mode and the non-archive log mode is that only cold backup can be performed in non-archive mode, and only full backup can be performed during recovery. data during the last full backup to system error cannot be recovered. archive mode supports hot backup, Incremental

necessary.Ii. Archive process ARCH. There are two modes for managing redo log files: Archive and non-archive. When switching logs, if you do not archive the original log files but directly overwrite them, it is called non-archive mode. On the contrary, when writing the next log file, the target log file will be archived first, which is called the archive mode. The archive process ARCH is responsible for copying the fully-filled redo log files to the archive log files after switching the redo lo

Oracle Archive Log configuration query Archive Log is a non-active redo Log backup. archive logs can be used to keep all redo history records. When the database is in ARCHIVELOG mode and the log is switched, the background process ARCH will save the redo log content to the archive log. when a media failure occurs in the database, you can use data file backup, archive logs and redo logs to completely restore the database. log operation mode: archivelog noarchivelog 1. Change log operation mode: C

Alternatively, you can do one of the following: In some systems, there are fast processors and relatively slow disks, and these processes may be able to put information in redo lgwr When writing data to a disk, fill up the remaining buffer. Therefore, a larger log buffer will temporarily mask Disks are slow. In addition, you can choose one of the following operations: ■ Imp
