"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:
(1) Disaster-tolerant replication scheme based on sto
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.
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
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
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
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

Cloud disaster tolerance, as its name implies, is a cloud-based Disaster Tolerance System, which can be either in a remote location or local location.
The cloud disaster recovery system integrates the advantages of a local ha (High Available) system and a remote disaster
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
A Life Insurance Co., Ltd. is a joint venture of foreign insurance Company and state-owned large-scale investment operation Enterprise, its business develops rapidly, 05-06 years respectively in Beijing, Shenyang, Shandong set up a branch. Its plans for the next 3-5 years in the northern part of China to open branches in several cities, gradually expanded into medium-sized insurance companies. With the rapid development of its business and the increasing number of branches, the
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
destination, the driver must return a message at the start point, this is just like the TCP protocol sends an ACK response to the source end after receiving the data. The driver can run back without a car (send an ACK response packet separately ), you can also bring some return messages to the destination region (TCP can include ack response information in reverse traffic to improve efficiency ). However, in a disaster tolerance system, data is alway

As application availability and disaster recovery capabilities are increasingly valued, more and more companies are starting to adopt a dual-site strategy. Multi-site application availability solution technologies for geographically dispersed parallel systems (geographically dispersed Parallel Sysplex, GDPS) are also maturing, which can improve applicati
If you're like most administrators, you might be responsible for backing up your Exchange database every night and storing your backup records in a secure location. This is great--but just taking these steps may not completely get you out of a serious disaster. In this article, I'll describe three of the most important and best ways to make a disaster recovery fo
data, as in the case of aof logs. So every piece of data just needs to be written once.Another reason is that the Rdb file storage format and the Redis data in memory encoding format is consistent, do not need to do data encoding work, so the CPU consumption is much smaller than the AOF log load.Second, disaster recovery simulationSince persistent data is used for data
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
