Embodiment 1

[0027] figure 1 Shown is a flow chart of a method for controlling concurrency errors in an embodiment of the present invention, including the following steps:

[0028] S101. When the calling application end UA invokes an application service, perform encapsulation processing on the invoked application service, and add a trigger identifier.

[0029] In the technical solution of the present invention, after the application service is invoked, it will not be executed immediately, but will be sent to the local AM (Application Manager, application service manager) of the UA for processing. In order for the AM to schedule the application service correctly, the application service needs to be encapsulated first, and the main content of the encapsulation includes adding a trigger identifier for the application service.

[0030] We can add a sequence trigger flag to the application service, so that the AM can schedule the application service in a certain order. Sequential trigger flag...

Embodiment 2

[0046] In a preferred embodiment of the present invention, the service management center can learn which application services can be executed concurrently without error by analyzing the functions of the application services, and can further add events for these application services during the encapsulation process The trigger conditions enable these application services to be invoked in parallel, thereby further improving the processing efficiency of the system.

[0047] The following assumes that P1, P2, P3, P4, P5, and P6 serve different applications, and their corresponding functions are as follows:

[0048] P1: x=x+5;

[0049] P2: y=x+10;

[0050] P3: a=x+y;

[0051] P4: b=x-y;

[0052] P5: c=x / y;

[0053] P6: d=a+b+c.

[0054] When UA invokes the above services, UA's local AM will not only add sequential trigger identifiers (namely serial numbers) for P1-P6, but also analyze each application service (since there is no other application service before P1, it is not ne...

Abstract

The invention discloses a method and a device for controlling concurrent errors. The method for controlling the concurrent errors comprises: adding triggering identifiers into called application services; adding the application services added with the triggering identifiers into a task queue; and triggering the application services in the task queue according to the triggering identifiers when triggering conditions are met. Through application of the technical proposal, the method and the device not only can avoid errors caused by concurrent data operation of programs but also can not cause frequent execution failure of the application services, and effectively improve the stability and the processing efficiency of a system.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for controlling concurrency errors. Background technique [0002] Distributed Object (Distributed Object) technology provides a powerful solution for the development of software on the network computing platform. At present, Distributed Object technology has become the core technology for establishing service application framework and software components. In a distributed object computing (Distributed Object Computing, DOC) environment, each distributed object in the network, when serving as a service provider, is independent of each other. Therefore, the calling application (User Application, UA) in When invoking a service, application services (programs) provided by different providers may be triggered simultaneously. [0003] For multiple application services that need to be triggered in order to obtain correct results, if they are triggered at the...
