Embodiment Construction

[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] The core idea of ​​the present invention is: technical implementation is based on two parts, process scheduling service (and its configuration parameters) and application program interface (API) function. Process predefinition is realized by configuring parameter data in the database table. The communication between application service processes uses message queues, and all services are uniformly scheduled by the process scheduling service process according to the predefined process; through the application service program and the process For the implementation of the interface (API) function between scheduling service programs, the application service program only needs to pass relevant parameters into the API function to r...

Abstract

The invention discloses a flow attempering method of application course to resolve problem that method of flow attempering realized by adopting command scenarios mode is single, and can not fulfill multiple application course attempering under UNIX (Linux)envirenment. Said method setting flow attempering serving program includes: reading prearranged service course information; creating output message queue and input message queue corresponding with said service course configuration message; reading single prearranged course control information, writing into input message queue corresponding with service when executes attempering, reading output message queue when attempering executed is returned. It also includes: setting flow attempering serving program and interface function of application program for application program, developing efficiency is increased greatly. The invention realizes combining attempering in single course/multiple course, synchronization / asynchronism multiple application courses under UNIX (Linux)environment, function of load equilibrium and flow control can be realized.

Description

technical field [0001] The invention relates to program execution of a computer system, in particular to a method and a system for scheduling multiple application processes according to a predefined flow. Background technique [0002] Unix (or Linux) is a multi-user, multi-tasking operating system. At the same time, multiple processes can be executed at the same time. A process is an execution of a system program or application program in memory, and is an execution program currently running by the operating system. There is no one-to-one correspondence between processes and programs, and one program can be executed as multiple processes. Under the existing Unix system, process scheduling is implemented through system calls. The process scheduling of the operating system is mainly to realize the scheduling of each process in time slices according to the priority, so as to share resources (mainly CPU). [0003] The process scheduling of an application process (hereinafter ...
