I recently read "RMAN Recipes for Oracle Database 11g". for more information about [RMAN Recipes for Oracle Database 11g pdf download] I am a foreigner, I will write down some of the important operations so that you can check them later. If it works well, I will make a summary after reading each chapter. I hope this will be helpful to Oracle backup and recovery beginners. If there are any errors in the notes, you are welcome to leave a comment. The fi
For a number of unexpected incidents encountered in computer use, such as sudden power outages, virus damage, accidental restart will result in the loss of computer data, for the missing files are not irreversible, we can use some data recovery software to recover the lost data, if using data recovery software, we certainly have to choose the most professional , today's small series for everyone to bring ex
When the computer suddenly crashes or loses power, is the hard disk data lost? Did the important USB flash drive files be accidentally deleted? Computer poisoning, file loss or unreadable? The system suddenly crashes and important files are lost? The most feared use of computers is the loss of important data due to sudden and catastrophic failures, misoperations, computer virus attacks, hardware faults, and other natural disasters threaten the security of data files at all times. Therefore, how
Common data file backup and recovery common data file backup and recovery: Common Data Files refer to non-system tablespace, udo tablespace, temporary tablespace, read-only tablespace files. Common data files can be restored using a high-availability recovery policy, that is, they can be restored in the OPEN state. 1. When the instance is started, if the common d

The principle of transaction and database recovery The logical unit of data storage is the data block, and the logical unit of data manipulation is the transaction. A transaction is a user-defined set of sequence of operations, consisting of one or more related SQL statements, which is the basic logical unit of a database application. Transaction management technology mainly includes database recovery tec
The purpose of a full database restore is to restore the entire database. The entire database is offline during the restore. Before any part of the database becomes online, all data must be restored to the same point, that is, all parts of the database are at the same time and no uncommitted transactions exist. Under the full recovery model, the database can be restored to a specific point in time. The point in time can be the most recent available ba

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 methods obviously cannot meet these needs. Becaus

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
Trialrecovery is basically similar to normal media recovery. The redo process only occurs in the memory and data changes are not written to the disk. To put it bluntly, the test media is restored.
