摘要： A journaling method is provided for supporting a recovery when a system is abnormally terminated in a shared disk environment. When a system call operation to take part in a journaling is generated, in order to guarantee a recovery, a transaction is started and new transaction region is assigned. Then, a system is initialized and a transaction type is set up. Lock information on modified data is acquired and added to the transaction so that a transaction manages lock information. A reflection to a disk during a modification of metadata is prevented. Modified metadata added to the transaction and modified information on principal general data are recorded. Then, lock information connected to the transaction is released.

摘要： Provided are a method and apparatus for obtaining a minimum cost vector for making a skyline object in a multi-dimensional space. The method includes calculating respective vector values having a query point and respective moving points to which the query point is moved as both end points in a multi-dimensional space having a plurality of coordinate axes, and selecting a vector value whose moving point is included in a skyline and has the minimum distance value from the query point as the minimum vector value from among the vector values.

摘要： Disclosed is a dynamic load balancing system. The dynamic load balancing system includes a resource management master managing bare servers that do not execute services and having a hierarchical structure and a service master dynamically allocating the bare servers to a load balancing server or a service execution server or dynamically releasing the pre-allocated load balancing server or service execution server by the bare servers, in consideration of monitoring information on a state or performance of a server and service requirements to be provided.

摘要： A fractional caching method and an adaptive contents transmitting method using the same are provided. The fractional caching method includes the steps of setting up a divided location for dividing a certain object into two parts, receiving an evict request for acquiring a space in the inside of the cache, when the evict request is transmitted, dividing a plurality of objects stored in the cache into a prefix-Object located in the head of the object and a suffix-Object located in the tail of the object from the divided location, and removing only the suffix-Object of each object, wherein the divided location is set up at a size rate that a size of the prefix-Object is in inverse proportion to the number of the destination types.
