标准范围

本建议|国际标准旨在当需要承诺、并发和恢复。无论何时处理两个或多个分布式应用程序中的应用程序实体调用需要组织成一个原子操作。本建议|国际标准定义了单个协会用于协调两个协会的服务原子操作中涉及的应用程序实体调用。确定哪个应用程序实体调用参与原子行动的人员不在本建议|国际标准的范围内。本建议|国际标准确立了协调使用CCR的一般原则当一个原子操作涉及两个以上的应用程序实体调用时，或当需要恢复时，提供服务失败后需要。协调多个关联和相关的应用程序实体调用通过参考规范结合本建议实现原子行为|国际标准。本建议|国际标准仅适用于规范为参考本建议|国际标准。本建议|国际标准未规定单独的实施或产品。事实并非如此约束计算机系统中实体和接口的实现。不要求符合本建议|国际标准。本建议|国际标准包括适用于参考的合规性要求规格本建议|国际标准中定义的CCR服务要求CCR协议版本2（或正在使用更高版本）。

This Recommendation | International Standard is intended for reference by other specifications when the functionality ofcommitment, concurrency and recovery is required. It can be referenced whenever the processing of two or moreapplication-entity invocations in a distributed application needs to be organized into an atomic action.This Recommendation | International Standard defines services that are used on a single association to coordinate twoapplication-entity invocations involved in an atomic action. The determination of which application-entity invocationsare involved in an atomic action is not within the scope of this Recommendation | International Standard.This Recommendation | International Standard establishes the general principles for the coordinated use of the CCRservices when more than two application-entity invocations are involved in a single atomic action, or when recovery isrequired after failure. The coordination of multiple associations and the related application-entity invocations thatconstitute an atomic action is achieved by a referencing specification in conjunction with this Recommendation |International Standard.This Recommendation | International Standard is only applicable to a distributed application whose specificationreferences this Recommendation | International Standard.This Recommendation | International Standard does not specify individual implementations or products. It does notconstrain the implementation of entities and interfaces within a computer system.No requirement is made for conformance to this Recommendation | International Standard.This Recommendation | International Standard includes requirements for compliance that apply to a referencingspecification.The CCR service defined in this Recommendation | International Standard requires that CCR Protocol Version 2 (or alater version) is being used.
