Cluster device batch file transmitting method and file transmission device

Abstract: Command device in cluster device set assigns grades for member devices. The method includes following steps: (1) under control of command device, and through command device to log on file server of loadbearing files, the member devices at first level down loads files from file server and stores them; (2) under control of command device, logging on the member devices at the next higher level, the member devices from second level to second level counted from last down load files and store them; (3) under control of command device, logging on the member devices at second level counted from last, the member device at last level down loads files and stores them. Ensuring transmitting files in short time at batch, and lowering load of the command device in cluster device set, the invention transfers files for member devices in cluster device set in batch.

Towards Efficient Deployment of Cloud Applications through Dynamic Reverse Proxy Optimization

Abstract: With the increase of users and the deployment requests, the issue of dynamic deployment in PaaS becomes prominent. Different approaches of application deployment have been deeply discussed, but the issues like fast response to a large number of concurrent deployment requests are rarely focused. In this work, we extend Nginx as a dynamic reverse proxy to support dynamically remote configuration for better elasticity of cloud applications in PaaS, and then further optimize it for improving performance under a large number of concurrent configuration requests. Three optimization approaches are proposed: Batch Request Committing (BRC), Batch File Processing (BFP) and In Memory Configuration (IMC). We give a detailed implementation of each method, and a qualitative analysis on three optimization approaches has been made. Finally, a series of experiments are presented to validate the optimization effect. The experiment results show that the maximum throughput per second has increased significantly, and the average response time of each request has decreased dramatically.

Updating a master file—yet one more time

Abstract: For several years I have been teaching a file updating algorithm which is essentially the same as that in Dwyer's admirable paper [1]. There is one unjustified objection to the algorithm that perceptive students and people with batch processing experience almost invariably raise and which is not addressed by Dwyer. The objection is based on a situation which arises in a batch processing environment with several users, where key-ordered sequential update is used.

Batch file processing method and system

Abstract: The present invention discloses a processing method of batch files as well as an inquiry method and a system of batch files by applying bank risk information. The present invention relates to the field of data processing and solves the problem that multitudinous inquiry-demanded files sent by banking institutions fail to be processed rapidly and efficiently. The method includes searching regularly to see whether inquiry-demanded files exist; acquiring inquiry-demanded files in a multi-process and parallel way; conducting a one-off retrieval of various risk information tables to examine whether objectionable information matching the inquiry-demanded files exists correspondingly to each inquiry-demanded file; and generating query result files containing the objectionable information. The system consists of a database, a file-shared space, a regularly polling module, a plurality of data-retrieving modules and a subsystem of file receiving and sending. The present invention not only achieves a demand for automatization, but also has the advantages of being fast, stable, safe and supporting a concurrent process by multitudinous institutions. The present invention plays a role in standardizing the credit flow of the credit card issuing by internet-entry institutions and better avoiding the risk of the credit card issuing.

Command file processing and authorizing system and method with variable access levels

Abstract: A command file processing system includes a terminal which inputs a password and commands which are to be executed. A command table prestores command names in correspondence with information which indicates passwords authorized to execute the commands. A command made up of the commands are to be executed and are registered in the command file. A judging part judges whether or not the password input from the terminal has authority to execute an arbitrary command which is to be registered in the command file when registering the commands in the command file. The judging part controls the command file creating part to reject the registration of the arbitrary command in the command file when the password has no authority to execute the arbitrary command.
