Abstract: Access to objects of a computing environment is managed. Access to an object of the computing environment is prohibited via one cached entity corresponding to the object, while access to the object is allowed via another cached entity. The cached entities are concurrently maintained for a period of time, but the one cached entity is in a shadow state. In one example, the cached entities are session locks and the object is a file system object.

Abstract translation: 管理对计算环境对象的访问。 通过与对象相对应的一个缓存实体禁止访问计算环境的对象，同时通过另一个缓存实体允许访问对象。 缓存的实体同时维护一段时间，但是一个缓存的实体处于阴影状态。 在一个示例中，缓存的实体是会话锁，对象是文件系统对象。

Abstract: PROBLEM TO BE SOLVED: To present various copy on writing embodiments in a computing environment. SOLUTION: In this system, a certain copy on writing embodiment includes using a reading mapping table in order to execute first virtual block-physical block mapping to be used to read a data block of the file that is subjected to copy on writing from a physical storage device for correction and using a different writing mapping table in order to execute second virtual block-physical block mapping to be used to write a block with corrected file data to the physical storage device. In this case, copy on writing for the data block is accomplished by using a single writing operation. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide various copy-on-write execution forms in computing environment. SOLUTION: These execution forms include: the use of a reading mapping table to execute a first virtual block-physical block mapping to be used to read blocks of data in the file to be copied-on-write from a physical storage device for correction; and the use of different write mapping tables to execute a second virtual block-physical block mapping to be used to write the block having corrected file data into the physical storage device. Here, the copy-on-write operation of block of data is achieved by using single write operation. In another embodiment, distributed copy-on-write operation of a file in client-server environment is presented. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method for facilitating error processing of a computing environment provided with a file system. SOLUTION: A portion of functions of an entity is automatically frozen in response to the matter that the entity of the computing environment such as a client of the file system acquires at least one error notice. The acquisition of the error notice responds to an event of a second entity of the computing environment, for example, a server, etc., of the file system. Finally, the frozen function is thawed to continue processing. COPYRIGHT: (C)2005,JPO&NCIPI
