In order to improve the utilization of resources in the enterprise information portal middleware platform,a multi-tenant oriented resource management framework is presented.According to the characteristic of resource in portal scenario,a resource model is established.Metadata is used to describe the mapping relationship between tenant and resource.For different types of resources,specific mechanism for resource sharing and isolation is provided.This approach can not only improve resource utilization,but also encapsulate the details when resource users accessing tenant sensitive resources,so that the management problem for logical resources in multi-tenant environment is simplified.In the end,this framework is applied to a portal middleware named OncePortal,and make experimental analysis on the prototype.The result prove the feasibility and effectiveness of the framework.
