What Is Cluster Database

Once the Cluster service is installed and running on the server, the server can join the cluster. Clustering can reduce the number of single points of failure and enable high availability of clustered resources. 　　The following sections briefly describe node behavior in cluster creation and cluster operations. Note: For information on installing the cluster server, see the Windows server http://www.aliyun.com/zixun/aggregation/19058.html >2003 product family ...

This article describes in detail how to deploy and configure ibm®spss®collaboration and deployment Services in a clustered environment. Ibm®spss®collaboration and Deployment Services Repository can be deployed not only on a stand-alone environment, but also on the cluster's application server, where the same is deployed on each application server in a clustered environment.

Cluster is a hot topic, in the enterprise more and more application of Linux operating system to provide mail, Web, file storage, database and other services, with the growing application of Linux, high availability and http://www.aliyun.com/zixun/aggregation/ 13996.html "> Load balanced Linux cluster is also developing gradually in the enterprise. The low cost, high performance and high scalability of the Linux platform enable the Linux cluster to meet at a low price ...

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

November 2013 22-23rd, as the only large-scale industry event dedicated to the sharing of Hadoop technology and applications, the 2013 Hadoop China Technology Summit (Chinese Hadoop Summit 2013) was held at four points by Sheraton Beijing Group Hotel. 　　Nearly thousands of CIOs, CTO, architects, IT managers, consultants, engineers, enthusiasts for Hadoop technology, and it vendors and technologists engaged in Hadoop research and promotion will be involved in a range of industries from home and abroad. In S ...

Using the latest 4, 8-way IA server architecture of High-performance server cluster system, the use of the leading VI (Visual Interface) technology, effectively eliminates the communication bottleneck between nodes in the system, and the system uses load balancing technology so that user equipment can be fully utilized,    and achieves 4 9 reliability, has the extremely high product price-performance ratio, provides a strong database server platform for the Internet application. ...

What is Cluster? There are two common Cluster (clusters) architectures, one is Web/internet Cluster system, which is to place data on different hosts, that is, multiple hosts are simultaneously responsible for one service, and the other is the so-called parallel operation! Parallel operation is actually the work of the same operation, to the entire Cluster inside the CPU to perform a synchronous operation of a function ...

The concept of blockchain to technology has been around for a long time, but with the heat of the past two years, it has gradually become known by the market and many technicians.

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...
