What is the functionality of the recovery manager in DBMS ?

Introduction to the related topic of computer DBMS following below here:


What is the functionality of the recovery manager in DBMS ?


Let's discuss this topic is related to the computer DBMS following below here:


What is the functionality of the recovery manager in DBMS ?

There are some points on the computer system and database related topic of "What is the functionality of the recovery manager in DBMS?" following below here:


The functionality of the recovery manager in DBMS points are mentioned in figure and explained below the figure, such as manages data and info, work also on network fb, to make a backup db etc. What is the functionality of the recovery manager in DBMS ?
The functionality of the recovery manager in DBMS points are mentioned in figure and explained below the figure, such as manages data and info, work also on network fb, to make a backup db etc.

  • The database recovery manager is a term on the application software of database management system and recovery section
  • Recovery manager manages the data and information of files that contains valuable data for user
  • Recovery manager also works on the DBMS connected with network system
  • Recovery manager work on the additional storage to make a backup for saving the important database


Let's discuss the points above about the computer system and database related topic of "What is the functionality of the recovery manager in DBMS ?" explanation following below here:


The database recovery manager is a term on the application software of database management system and recovery section

The database recovery manager is a term on the application software of database management system and recovery section that means the recovery section is used when the user wants to save the database into the memory of the computer system which is a storage device known as permanent memory.

The computer system storage devices crash for some reason. 

Such as power cut off if the computer system is directly connected to the power supply without any UPS support.

Another reason is when the user directly closes the computer system in some case of hanging the operating system due to viruses or malicious files or may be deadlock conditioned through the button of the cpu cabinet or UPS power off button.

These are generally two big reasons or common reasons that make the system crash or storage device crash.

In that case the user needs to make a backup of the database on the particular additional storage device to retrieve the old database when the system crashes or the storage device crashes.

Another reason for system crashes is application software misbehaving on the device or computer system blocks and hangs activities on the computer system.

So, the database software makes backup on the storage device to install after if the system crashes. 


Recovery manager manages the data and information of files that contains valuable data for user

Recovery manager manages the data and information of files that contain valuable data for the user. That means the files which contain the information for the user are necessary to be recovered from the storage device if these files have been deleted by some reasons such as virus attack, format system due to malicious files, pirated application attacks etc. These are common reasons to remove the valuable file to protect from the corruption of the file into the storage device of the computer system.

The manager of the recovery section manages the files according to the user requirements, choosing these files which contain valuable content for the user's profits.

When the user needs to recover files from the memory of a storage device after using the protection of the antivirus application software.


Recovery manager also works on the DBMS connected with network system

Recovery manager also works on the DBMS connected with a network system that means the network system needs to connect with the database which is a combination of server to access the network system and memory storage device to store the data and information of the website and user as personal information.

Sometimes the database is damaged due to physical reasons or other programmatic reasons in the computer system and the database is lost due to the storage memory crash which is connected to the computer network system.

The recovery manager recovers the database from the storage device or additional backup recovery of the old database which has been deleted or removed from the database that connected to the computer network system.


Recovery manager work on the additional storage to make a backup for saving the important database

Recovery manager work on the additional storage to make a backup for saving the important database that means the recovery manager stores the backup database which has selected from the storage device of the computer system when the user needs to stores the backup of valuable files into the particular permanent storage device which has connected to the USB port of the computer system. 

The recovery manager works on the storage device which has connected to the computer system such as an additional storage device to make a backup to recover the database from the additional storage device. This is necessary when the user needs to format all the computer systems to remove malicious files or virus attacks on the storage device of the computer system to prevent the system crash and storage crash due to the reason of virus or malicious files.

After formatting the data from the storage device of the computer system the backup database from the additional storage device can recover the old database that has been removed from the computer system.

I am exploring the points on if data centers uses a SAN how it is bigger than SANs?

Is data centers using a SAN and how much are data centers bigger than SANs? The data centers are used to provide the big data analytics for the website and companies to provide the processed data for making different types of informed decisions at a large amount of data processing in the data centers because it is a very big area to install into the building and many buildings if it requires to install into many buildings. The large requirement of data centers installation is necessary because the data centers uses many types of computers, storage devices, network attached storages, network devices such as:- servers, switches, hubs, routers, bridges, repeaters, gateways etc. data cables and different types of network equipment to use in the data centers to make a large area of data processing for the companies uses and major projects for website at larger industrial area for website for data processing. The storage area network is used to provide the high performance of data processing...
