-S, it can manage all the user's storage resources, but the current situation, it is still in the early stages of development: it can only find a variety of problems, but cannot take the initiative to manage. Discovery functions are of course important for implementation management, but it is only the first step of management, and the problem of SMI-S is that discovery functions are basically all of it. In addition, the currently authenticated SMI-S Management Console only discovers HbA (host b

list, report, and show commands of RMAN can be used to display information in RMAN repository. RMAN repository is mainly stored in the control file of the backup target database. Initialization parameter: control_file_record_keep_time is used to control the time when the backup record is saved in the control file. After this time, the record information will be overwritten and reused by the updated backup information. Recovery catalog You can use the recovery catalog to save RMAN Repository Inf

magnetic tape, the part on which tape is wound for later use. A more modern interpretation of spool comes from the flowchart drawing icon of a spool of thread, which, in IBM-ese, represents the (perhaps) temporary storage of data on a magnetic disk drive, under the control of an operating system task.History [edit] In a computer system peripheral equipment such as printers and punched card readers and punc

Database Backup optionsWhen backing up a database, you need to know several backup options, such as overwriting media and transaction logs. When talking about the coverage media, you must first understand this concept, otherwise you will not be able to talk about it.● Media set: an ordered set of backup media (tape or disk files). One or more backup operations are performed on a fixed type and quantity of backup devices. The number of backup devices u

Sometimes we need to add hot-swappable SCSI hard drives to the online system, we cannot stop at this time, we can add the new hard disk to the system with the following instructions# echo "scsi add-single-device 0 0 1 0" >/PROC/SCSI/SCSI//Add HDD# echo "scsi remove-single-device 0 0 1 0" >/proc/scsi/scsi//delete HDDFor the four numbers in the directive, the SCSI, channel, ID, and LUN numbers, respectivelyWe can view this information for SCSI drives in the system by following the instructions bel

First, operating system introduction 1, manual operation--punch cardThe first computer was born in 1946--in the mid 1950s, computer work was still being done by hand. There is no concept of operating system at this time.The programmer loads the perforated paper tape (or card) corresponding to the program and data into the input machine and then initiates the input machine to enter the program and data into the computer memory.Then through the console

Through the SQL Server database backup and restore knowledge and summary (i), I believe you have a more in-depth understanding of data backup and restore, in the above I do not have to do the transaction log analysis, this recommendation Song article, the transaction log did a more detailed explanation: http:// Www.jb51.net/article/31038.htm. This article will focus on some of the key options for backup and restore for data backup and restore explained above. Database backup Options When back

backup operation. 1, can achieve the Rman performance As mentioned in the Rman white Paper, the rate at which data can be backed up and recovered at tape is at 1TB per hour under current technical conditions. With the continuous development of tape backup technology, this rate is likely to become even greater. 2, the use of appropriate hardware If you want higher backup performance, the first considera

In addition, the logical log records changes to the database after the last data backup, so the logical log is also used to recover the system when there is an unexpected system. 1.1 Data backup Online Dynamic Se

I believe that many system administrators are doing the same job every day-backing up data. Once the system fails and data recovery is required, the system is powerless. It would be nice to set a fixed time every day for the system to automatically back up data! Next, I will talk about the automatic backup of Oracle databases in a UNIX environment based on my practical experience. We plan to allow the database to perform export backup at a.m., copy the backup file to the

Through understanding and summarizing SQL Server database backup and restoration (I), I believe you have a deeper understanding of data backup and restoration, I did not analyze the transaction logs in the above article. Here I recommend song xiaojian's article to explain the transaction logs in detail: http://www.jb51.net/article/31038.htm. This document explains how to back up and restore data, and describes some key options for backup and restoration.Database Backup options When backing up a
