Description
Technical Field
The invention relates to the field of financial science and technology, in particular to a cluster report system based on a ring mechanism of an upper exchange.
Background
The escrow mechanism for the exchange is tied to a specified transaction regime. The client performs the transaction at a seat appointed by a security dealer, and only connects with a database server (SqlServer) to report during the transaction. Seat resources are important channel resources of security dealer, and the most common method of security dealer is that a plurality of clients use the same seat, and especially a large number of scattered households share one seat. But the most direct impact of seat sharing is the sharing of traffic. If the customer is used to trade a high frequency of transactions and the demand for flow is high, it is very disadvantageous that the flow rate is limited. Because of the flow rate control of a single database server, even if a client can use one database server alone, the flow rate control of a single database server is also subject. Thus, expanding the flow rate is very meaningful to customers with high frequency of transactions.
In the existing seat assignment mode, if the database server fails, a mode of starting a standby database server in an emergency must be adopted, and the report service is interrupted briefly; if a server where the database server is located is in serious failure, the main-standby switching needs longer time. Therefore, in response to the occurrence of a fault, it is necessary to employ online fault isolation.
If a single customer singly shares one seat for reporting, the resources are wasted when the customer transaction is low. If a plurality of clients with transaction peaks in different periods share the database server to perform transactions, the resources of the database server are greatly saved when the resources of the database server are rare.
