Embodiment Construction

[0035] The following is an example to illustrate the implementation steps. The component echo simply returns the incoming string, and the client program calls the function of the component echo through the static proxy library.

[0036] 1. Write component echo

[0037] #ifndef ECHO_H

#define ECHO_H

#include

using namespace std;

extern "C" {

string echo(const string & str);

}

[0038] echo.h file

[0039] #include "echo.h"

extern "C" {

string echo(const string & str){

return "echo:"+str;

}

}

[0040] echo.c file

[0041] 2. Compile echo.c and connect to generate libecho-1.0.so echo.h file echo.c file

[0042] 3. Write the component registry

[0043] 4. Write a static proxy (can be generated using tools)

[0044]First use typedef to define the type of the service interface function, and then define the proxy implementation of the interface function, which is statically bound with the client pr...

Abstract

This invention disclose a large scale parallel on-line thermal mobile method which is base on the C / C++, and the character is that the call of client and server is isolated by the agency, the usage of which dynamic base and function is determined by the dynamic agent, and in the unix the realization of this function is depended on dlopen and dlsym. This invention solves the dynamic refresh of software version in the large scale parallel in-line dealings system, especially on the constant running of the system; it can be refreshed automatically at the same time according to the assembly register.

Description

technical field [0001] The invention relates to a telecommunications online transaction method, in particular to the problem of dynamic update of software versions in a large-scale concurrent online transaction system, which automatically realizes synchronous update of software according to the component registry. Background technique [0002] The telecommunications business support system is a large-scale concurrent online transaction system, which needs to provide various telecommunications services for tens of millions of telecommunications users in the province. Among them, account opening, payment, inquiry and other services handled by users at the business front desk must be completed in real time Online transaction (OLTP), under normal circumstances, the daily transaction volume can be more than 1 million, and the concurrent transaction volume per minute can reach more than 4,000 during peak hours. The availability of the online transaction system directly affects the ...
