VCA (virtual client access) based grid information integration strategy is proposed in this paper that brings forward one efficient application framework with loosely coupled architecture. It encapsulates the virtual clients that are realized based on the API of the information systems as grid services to enable the grid can access the information systems as real client. VCA mode can be combined with local access control and task management seamlessly, and solve the resource conflicts between grid and local users so as to support the information sharing and cooperation widely and efficiently. The experiment shows that VCA modes can support the information sharing and cooperation widely and efficiently.

Resource information service, as a key component of grid, is the basis of the resource allocation, resource performance evaluation and prediction. The validity of the resource information service directly influences the availability of the whole system. One of key points to make information service work well is the precise of the information collected, how to get the valid system information with low system cost has became a difficult problem in current information service. In this paper, we propose hybrid resource information service architecture based on grid monitoring architecture to promote the validity of the resource information service in grid. HRIC is an improved information service architecture that utilizes resource changing self-monitoring mechanism to offset the blind spot of the periodical information collection and combine the advantages of two traditional information collection methods - periodic collection and stochastic reporting, thereby improving the accuracy of resource information service. Compared with the existing resource information systems, HRIC's performance has been validated by several applications
