Abstract: PURPOSE: A system for controlling time-based metadata cache coherence and a method thereof are provided to maintain cache coherence by maintaining the coherence between the metadata stored in the metadata cache of a web application server and the metadata stored in database, based on the time of SaaS(Software as a Service) platform. CONSTITUTION: A list entry is selected in metadata cache, wherein the list entry has the same tenant/service ID as the tenant/service ID included in a service request(S125). The return value that the time stamp value of the list entry is subtracted from present time is compared with the timeout value of the list entry(S135). If the result value is smaller than the time-out value, the validity check of the list entry is requested to a data server(S140). The list entry is updated by the acquisition of the metadata of a latest version from the data server according to validity check results(S160).

Abstract: PURPOSE: A device and method for creating a duplication object by a remote control is provided to move a server object embodying code of a server object prepared in a remote system 1 to another remote system for creating a copying object and to execute the moved server object embodying code without a user's intervention. CONSTITUTION: If a server object registration request is received in a server object processing unit(301), a server object is registered(302). In addition, it is judged whether a copying object of the server object is created(303). In case that a copying object of the server object is created, a copying object process data structure including a packet identifier, a message kind identifier, a target host name, a copying object name, a copying object key, and a server object embodying code necessary to a copying object creating request is created(304). The created copying object process data structure is converted into a packet having a proper type to be transmitted through a network(305), and is transmitted to a network(307) through a communication channel opened in accordance with a used communication protocol(306).

Abstract: 본 발명은 원격 객체 메소드 호출에서 대리 객체의 입력 및 출력 전달 인수 처리 방법에 관한 것이다.
본 발명에 관련된 기존의 방법에서는 전달 인수를 처리하기 위해서 별도의 클래스나 변수를 두는 방법을 사용하고 있다. 그러나 이러한 방법에서는 전달되는 인수의 모든 데이터 타입마다 별도의 클래스를 정의해야 하기 때문에 대리 객체의 정의가 매우 복잡하며, 또한 실행 시간이 늦어지는 등의 문제점들이 있다.
본 발명에서는 전달 인수를 처리하기 위해서 전달 인수 목록, 입력 전달 인수 목록, 그리고 출력 전달 인수 목록을 사용하므로써 대리 객체 정의를 단순하게 하며, 실행시의 처리 속도를 빠르게 한다.-
