When the control file backup and recovery instance is started, the process must read the control file and write the control file. Therefore, if a control file is damaged, the instance cannot be mounted. That is, the control files in this phase are indispensable. If the disk is damaged, it can only be started to the NOMOUNT state. Backup control file backups inclu

When we use a database, we always hope that the database content is reliable and correct, but due to computer system faults, hardware faults, software faults, network faults, process faults and system faults) the operation of the database system is affected, the correctness of the data in the database is affected, or even the database is damaged, so that all or part of the data in the database is lost. Therefore, when the above fault occurs, we hope to re-establish a complete database, which is

MySQL online backup and recovery tools --> XtraBackup 1 Overview of Xtrabackup principles Xtrabackup is a tool used to back up InnoDB data. It supports online Hot Backup (data read/write is not affected during Backup) and is a good alternative to InnoDB Hotbackup. Xtrabackup has two main tools: xtrabackup and innobacku

Backup and recovery of spatial data in ArcSDE: With the increasing requirements of GIS application systems in terms of complexity, integration, and concurrency, the amount of space data required by the system is rapidly increasing. At the same time, users' demands for concurrent access to spatial data are becoming increasingly prominent. The traditional file storage and representation of spatial data meth

This paper mainly describes how to improve the DB2 data backup and recovery efficiency of practical steps, in the design of data backup and recovery scenarios, we mainly consider two aspects of the problem.The first is whether the backup and

The two problems are: whether the backup and recovery policies are secure, that is, whether the database can be backed up in a timely and accurate manner. The second is to consider the high efficiency of the DB2 data backup and recovery solution. If it takes several hours to back up or recover a DB2 database, the

community uses the branch method to avoid this risk. Data is no longer important to us. How can we ensure the security of data as much as possible? What should we do when our data is lost, therefore, data backup is too important for our data security. Data is no longer familiar to us, but it is also most common. We are exposed to various types of data every day, and the data records our common business information, therefore, data is very important f

Oracle backup recovery detailsI. Backup method:1. In non-archive mode, only cold backup can be performed2. In archive mode, hot backup or cold backup can be used. (Online log files of temporary data file control files)Ii. Cold

DB2 logs are divided into two modes: log loop and archive log, which are non-archive and archive modes. The following describes the two methods and their relationship with backup archiving settings. 1. Log Loop This is the default mode, that is, non-archive mode. This mode only supports backup offline) offline backup, and DB2 needs to stop the service during the

Article Title: Application of Backup Recovery Technology in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This article describes how to use backup scripts, commands, and commercial software in Linux to reasonably and

Normally, when the current control file is lost or the current control file is inconsistent with the control file to be restored, we need to re-create a control file or use unsing Backup controlfile to restore the control file. To put it simply, as long as the backup control file is inconsistent with the current control file to restore the database, you need to use the unsing
