The application server is deployed with a resource management module (NRM), and has functions of receiving SRM instructions, issuing configuration, executing applications, and the like. And the domain management server loads the service data from the database and generates a data file from the service data. The domain management servers are distributed on the host computer, and usually, two or three domain management servers are deployed in each computer room to realize that the domain management servers extract the service data from the service database. The host refers to a host corresponding to the application server. A peer-to-peer network (P2P network) is formed between the application server and the domain management server. The application server and the domain management server complete the downloading of the data files on each host computer through the P2P network, and execute the service according to the downloaded data files. The following describes specific embodiments of the present invention.

The application server downloads the data file according to the BT protocol which is signed with the domain management server in advance, and performs service processing according to the service data in the data file.
The embodiment of the invention extracts target business data from a business database through a domain management server to generate a data file, and distributes the data file to an application server based on a BT protocol so that the application server performs business processing according to the data file; according to the embodiment of the invention, the domain management server extracts the target service data from the service database to generate the data file, and distributes the data file to the application server and the common application server to perform service processing according to the data file, so that the application server is prevented from directly downloading the data file from the service database, the CPU occupancy rate of the database server is reduced, and the data loading efficiency is improved.
In some embodiments, a configuration file is preset on a host where the domain management server is located, and the configuration file includes corresponding information such as a loading mode between the service processing process and the target service data, and an access key value of the target service data. And extracting target service data from the service database according to the configuration file, and generating the target service data into a shared memory. And the accuracy of target service data extraction is ensured by means of configuration files.
In some embodiments, the domain-management server distributes the data file to the application server according to the following steps as shown in fig. 3.
Step 210: the domain management server divides the data file into a plurality of block files and generates a seed file.
The seed file stores information of all the block files, such as an address, index information, Hash value, and the like of each block file. The block file is to divide the data file into a plurality of sub-files, and the information stored in each block file is different. The division manner may be an average division or a non-average division, which is not limited in the embodiments of the present invention.
Step 220: and the domain management server distributes the seed file to the application server so that the application server analyzes the seed file to obtain the information of the block file.
Wherein, the domain management server distributes the seed file to the application server according to the BT protocol. And the application server analyzes the seed file according to a protocol preset in the application server. The protocol preset inside the application server may be set by a person skilled in the art, for example, http protocol and the like.
Step 230: and the domain management server distributes the block file to the application server so that the application server downloads the block file according to the information of the block file to obtain the data file.
The domain management server distributes the block files to the application server according to the BT protocol, the application server downloads the block files according to the information of the block files obtained by analyzing the seed files, and the data files are obtained after all the block files are downloaded.
In some embodiments, the application server communicates with the domain management server to obtain information about the partitioned files being downloaded by other application servers. If the information of the block files being downloaded by other application servers is not contained in the block file set downloaded by the application server, the application server downloads the block files.
The embodiment of the invention obtains the block files by blocking the data files and respectively distributes the block files to each application server, thereby improving the distribution efficiency of the data files.
