I recently read ERP materials. Looking at a lot of RMA, I thought it was RMB. I found the information. In the past, RMA was used to return the goods. Find a detailed one and record it. :RMA (return) Business process RMA has three Processing Methods: repair return repair, replace return, and return. Generally, it is req

3.3 Coordinator mode
The Coordinator mode describes how to maintain system consistency by coordinating the completion of tasks involving multiple participants (each participant contains resources, resource users, and resource providers. This mode proposes a solution that enables tasks involving multiple participants to be completed, or tasks of all participants are not completed. This ensures that the sys

Zookeeper is the role of coordinator in Distributed system, which can be applied to the implementation of leader election, distributed lock, configuration management and other services. Below we learn and understand zookeeper (ZK) from the three aspects of API, application scenarios and monitoring provided by zookeeper.
ZK API
ZK manages stored data in the form of a UNIX file system tree structure, as shown below:
Each of these tree nodes is called
The default values are 5, 20, 6, and 30,000 nodes in total.Max_depth determines the maximum depth of the network. The Coordinator (Coordinator) is located in depth 0,max_depthParameters limit the physical length of the network, which defaults to 5 and cannot exceed 15.Max_children determines whether a route (Router) or a coordinator node can handle a son's dayThe
This mainly covers the bindings between the coordinator and the terminal.This mechanism uses a button press or other similar action at the selected devices to bind within a specific timeout perio D. The End Device Bind Request Messages is collected at the coordinator within the timeout period and a resulting bindin G Table entry is created based on the agreement for Profile ID and cluster ID.

In a project I have experienced, I need to transmit data between two database servers, and there are security devices such as firewalls (network switches) at intervals. When we use distributed transactions, we encounter problems, DTC cannot work normally in this environment. As a result, I found this article on the Internet and quickly solved the problem according to the method described in this article.
