"Guide" This article describes the current major technologies and solutions for remote replication and disaster recovery of Oracle databases.
Currently, there are several technologies or solutions for remote replication and disaster tolerance for Oracle databases:

network backup system based on the backup server, client, and storage device. The three-party architecture prevents the backup server from being involved in data backup and recovery data transmission, balances the system load and increases the system concurrency. It also describes the overall architecture of the network backup system, the backup server, backup proxy and Storage Server Subsystem functions, and communication interfaces, the network bac
While it is important to have a disaster recovery plan that includes programs that prevent replication failures, every domain controller in the core site is not responding, it is difficult to happen. The more common difficulty is due to hard disk crashes, poor network cards, file system degradation, Active Directory degradation, or a variety of minor problems that can cause damage to one domain controller.
When the master server suddenly fails or stops working due to other damages, it starts to start the VM that is synchronized with the master server and backed up, send an email to the administrator or send a notification directly to the mobile terminal of the Administrator. After the master server recovers, the VM includes the operating system, database, and application.ProgramAnd other related data are seamlessly migrated back to the original master server. To complete these operations, you only
I. Level of disaster tolerance
Disaster tolerance from the degree of protection generally divided into three levels: data level, system level, business level.
Data-level disaster-tolerant concerns are data that ensures that the user's original data is not lost or compromised after a disaster occurs. Data-level
With the development of the information industry, disaster recovery and backup have been accepted by many companies and enterprises. At the same time, the manufacturers of disaster recovery and backup also threw out a lot of new concepts and ideas. However, as a professional disast

From local backup to geo-replication to cloud-based disaster recovery, with the rapid development of cloud computing technology, and cloud services, the model is gradually accepted by the majority of enterprise users, data backup to the cloud is a viable data protection solution. Symantec, December 16, launched a new disaster
There is no need to say much about the importance of disaster tolerance to the enterprise, in a global economic environment that requires 24x7 operation, no enterprise can afford downtime, whether it is planned downtime (upgrades, maintenance, and repairs) or sudden outages (due to human error, handling failure, power failure, or even disaster events). But many companies have a business continuity plan to r
banks should basically be in levels four, 5 and six. The larger the total asset size, the higher the level should be.Disaster recovery level refers to the disaster recovery ability national standard level, the following brief for everyone to introduce six levels of content: Disaster
The rise of server virtualization and cloud computing technology does not mean that we no longer need good IT Disaster Tolerance planning, as well as the tape technology that may be used in these planning. The following are some disaster tolerance techniques mentioned in JonToigo's keynote speech at its StorageDecisions conference.
As the CEO and Management Partner of ToigoPartnersInternational, Toigo belie
It can be proven that the two most important factors in testing the IT disaster recovery plan are keeping the scheduled updates and testing whether the plan is valid at a critical juncture.
Ideally, each year you will lead the disaster recovery team to rebuild and restore the original product system without error in t
the last year successfully received tens of millions of Yuan Angel investment, the current new round of financing is ongoing.Now, more and more enterprises are aware that the self-built data backup center is not only a large upfront investment, but also the maintenance of operations need to invest a larger workforce. As a result, data cloud backup storage has become the most used area in the cloud computing industry today. Larger disaster backup devi
What should you do if the recovery data grows too large and traditional disaster recovery methods cannot achieve the goal? Some new technologies, such as deduplication, storage Tiering, and data management policies, can help you reduce the high cost of disaster recovery, at
minimum switching time is about 15 seconds, or even shorter.

mechanism, the client may read the old data in the standby node, if the business requires strong data consistency, you can set the read-only main option in the read request, so that the read request will be forwarded by the interface layer to the master node, in this case, the standby node is only used for disaster recovery, not provide services.In order to ensure the data consistency of the primary and st

Disaster recovery is a technical precaution and measure that is taken back from any event that has a negative impact on the IT system .. A typical approach is to build repetitive infrastructure to ensure availability of backup capabilities in the event of a

Data-level disaster recovery
Data-level disaster recovery focuses on data, that is, after a disaster occurs, the user's original data will not be lost or damaged.
Data-level disaster tolerance is relatively basic. Among them, the
