smarsh archiving

Content Summary Archiving (archiving) – consisting of a range of policies, processes, and technologies – has slowly become a necessary business for companies that comply with laws, regulations, and complex information technologies. While the company is facing an annual growth in critical data, storage capacity management technology bottlenecks have not improved. And the company also faces other challenges,

question: As databases grow larger, the challenges to performance and management are growing. Each query may need to find more data pages, especially if the query has a scan operation, which can cause the query to become more and more slow. At the same time, there will be more and more data to be backed up and backup operations continue to grow longer. Backup files and databases use more and more data files, and so on, a whole range of problems will follow. Data

Archiving objects is similar to copying objects, that is, the Protocol is required. Why is there no archiving protocol for nsstring and nsnumber objects in the past? Because they come with their own. Therefore, if we want to archive custom objects (instead of the default objects in Foundation), we need to introduce the archive protocol For example, declare a user class, create an object user1, archive thi

Oracle archiving operations, oracle archiving logsOracle uses redo log files to record database operations, But redo log file groups are used cyclically. When all log files are filled up, the system automatically switches to the first log file, of course, the database administrator can also use commands to manually switch between them. When the log file is recycled, the existing Log File Content in the log

IOS file operations and custom object archiving (serialization) and anti-archiving (deserialization) IOS allows you to create, read, write, move, and delete files. 1. File Creation: // Set the location of the file stored in the text box NSString * strFilePath = [NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex: 0]; // specify the file name NSString * fileName =

First of all to say what is archiving and archiving, everyone under windows are ARJ WINZIP or RAR, such as software to package the software process compression, the same Linux inside also have similar software their suffix name is *.tar *.gz *.tar.gz bz2 *.z. BZ2 is a software compression package that is more powerful than compression. Now let's take a look at these commands. 1.compress compressed files are

The new features of In-database archiving are introduced in Oracle Database 12c, which allows users to archive data by marking data rows on the table as inactive inactive. These inactive data rows can be compressed into one optimization and are not visible to the app by default. This feature enables the functionality and requirements of this "tag delete" in the case of minimal changes to existing code.Before 12c:Some applications have the concept of "

using database archiving technology to solve performance degradation problem Many database administrators encounter the confusion that the size of the database file is growing as the business progresses. This brings great difficulties to the database management, on the one hand, to provide more and more high-performance disk capacity for online business, on the other hand, the performance of the database is getting worse. A new technology of database

1. Differences between the archive log mode and the non-archive log ModeIn non-archive mode, only cold backup can be performed, 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 backup, and partial recovery.You can use archive log list to check whether the archive mode is not the archive mode when the archive mode is in the status.2.
