core file
2.In another node of this cluster,an idle process of Apache server loads the Core file to resume the context of interrupted process,the net connections and the opened files of the process in succession. So the process migration of Apache server is implemented. And technique of the Apache server process migration based on the cluster is given.
5.After profound study on Dublin Core,a broadly identified MetaData standard for traditional library catalogs,the paper advanced a basic MetaDala in XML format for our experimental Digital Library system,along with i Is data structure requirements and DTD file specification. In the experimental Digital Library system,all types of MetaData and object contents are incorporated into a uniform management system based on XML and XML based RDF definitions,which ensures the integrity and inter_operational abi I i t.
6.Programe and deploy the procedure of server need five basic steps: Define this service’s interface, Implement the service, Define the deployment parameters, Compile everything and generate GAR file, Deploy service. The OGSI core is the Grid Service criterion ,it defined the Grid Service standard interface and behavior based on the WWW service.
