I. Description of the problem A project has an identical m machine, we have n tasks to deal with, task I processing time for TI. scheduling refers to the task of assigning tasks to the machine at run time, so that:(1) A machine can only handle one

Objective: This thing in the task scheduling aspect, has the very set, the study he has a period of time, oneself also tried to use in the project, but suffers from does not have this opportunity. These two days to the department to write a rest of

Quartz is an open source task scheduling framework, which provides a powerful task scheduling mechanism, while maintaining the simplicity of use. Quartz allows developers the flexibility to define scheduling schedules for triggers and to associate

Variant (variant) Variant types can theoretically store any type of data, which is why many people in Chinese call it "variants." It is strange for a programmer with a strongly typed language such as C + + to have a Variant (variant) of that type.

1 Why you need dispatchaction. If each request corresponds to an action, it causes too much action and the program looks bloated, so the program needs to lose weight (you can write a type of request to handle in an action), so the program is

several services. Each service must be listed in a dedicated dispatch table (this program defines an array of servicetable structures ). Each item in this table must be in the service_table_entry structure. It has two domains: Lpservicename: a pointer to a service name string. When multiple services are defined, this field must be specified; Lpserviceproc: pointer to the main function of the service (endpoint of the Service

pointer to a service name string. When multiple services are defined, this field must be specified; Lpserviceproc: pointer to the main function of the service (endpoint of the Service ); The last item of the dispatch table must be the NULL pointer of the service name and the main function field of the service. In the text example, only one service is hosted, so the definition of the service name is optional. Service Control Manager (

SummaryThe services under Windows NT are similar to the daemon processes under * nix, and more software are designed as servic

the operating system starts some tasks, such as scheduled programs (cron) and Finger daemons, before you can log on to the first user. In Windows NT, background tasks are called services. The service can run every time the NT is started, and no matter who logs in, it will continue to run. Windows NT services are implemented through general executable programs. The difference is that they follow a specific internal protocol so that they can communicate with the Service Control Manager (

Integrate existing Software Configuration Management System 1. Software Configuration Management StatusMost large outsourcing companies operate on projects, and SCM is also distributed across nodes in each project. SCM node information is only known to the project personnel. Different SCM types: CVs, clearcase, VSS, and perforce. After the project is completed

The Service Control Manager, which is called SCM, is it! In the Windows kernel, you can see her busy figure, can be said to be a system of service and drive housekeeper!SCM Housekeeper Qizaotanhei, and every time the system starts, so does she. With her own efforts, she finally took a place in the core of Windows, deploying many services and drivers. SCM What is

the service program is that main () calls servicemain () and servicemain () By calling handler () and executing the function mywork (), you have learned about the process of the service program and implemented the backdoor program step by step according to the above process. 1. Main () function of the program entry The entry of the service program starts from main (), but the difference is that the main of the service program is extremely simple, because it is only responsible for creating the
