DISTRIBUTED SYSTEM, METHOD AND DEVICE FOR MEMORY MANAGEMENT, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To realized automatic memory management with a small communication volume and a small memory area in a distributed system which allows movement of objects. SOLUTION: A remote access management means 113 of modules manages objects referring to external objects and objected referred to from the outside by reference weights added to respective objects. That is, the remote access management means 113 stores reference weights corresponding to the types of communication messages in object information of communication messages which the means 113 exchanges with external modules. For example an additional reference weight set by a reference weight management means 118 is stored in an execution request message to an external object. In accordance with reference weights set by this message exchange, a heap memory management means 115 also recovers unnecessary objects on a heap memory area 114 to the memory area.
