摘要： A data migration management system for preventing alteration such as rewriting or deletion, and migrating data between storage systems during an alteration prevention term. This data migration management system copies data from a logical device of a source storage system to a logical device of a destination storage system, and sets an alteration prevention setting for the destination logical device. Once the data migration management system acquires an alteration prevention status report from the destination storage system and confirms that the data has been migrated without alteration, it cancels the alteration prevention setting of the source storage system.

摘要： In the storage-based snapshot creation, a block-selection specifying unit provided on a NAS processing unit specifies a block, which becomes necessary for the generation of snapshot data, to a specified-block analyzing unit within a disk apparatus. Moreover, a disk controller generates the snapshot data on the block specified as the snapshot target, while making an inquiry to the specified-block analyzing unit. This makes it possible to create the snapshot in a storage-capacity reduced manner, and to specify the snapshot creation in a partition, file, or directory unit.

摘要： A compiling method, for use with programs to be executed on a computer with cache memory, which programs would otherwise generate decreased performance due to cache conflicts arising from conflicting cache access(es), for reducing the generation of such cache conflict(s) by reordering the order of memory reference code in the program such that conflicting memory references do not start before the completion of memory accesses to a memory block.
摘要翻译：一种用于在具有高速缓存存储器的计算机上执行的程序的编译方法，该程序由于冲突的高速缓存访问引起的高速缓存冲突而导致性能下降，以减少由于冲突缓存访问引起的高速缓存冲突，从而减少这种高速缓存冲突的产生重新排序程序中的存储器参考代码的顺序，使得冲突的存储器引用在对存储器块的存储器访问的完成之前不开始。

摘要： A program compiling method in which a procedure being compiled is split into a plurality of units referred to as segments, whereon optimization is carried out for each of the segments. Upon recompilation of the procedure, optimization of the procedure is redone not for the whole of the procedure but executed only on the segments which are affected by modification, while for the segments insusceptible to the influence of modification, object program obtained by the compilation or the intermediate codes available in the course of the optimization are reused. At several stages of optimization, intermediate results of the optimization are recorded, wherein upon recompilation, the intermediate results of optimization obtained in the preceding compilation are made use of up to the stage where no influence of modification makes appearance. The amount of processing involved in the optimization can thus be reduced even when the object program can not be utilized. In a mode for carrying out the invention, not only the interim results of optimization but also the contents of optimization executed are recorded. Upon recompilation, those of the optimization processings executed in the preceding compilation which are to be executed again can be performed rapidly by making use of the contents stored. The time taken for the execution of optimization processing to be re-executed can be reduced significantly.
摘要翻译：一种程序编译方法，其中正在编译的过程被分割成被称为段的多个单元，其中为每个段执行优化。重新编译程序后，重新整理过程不是整个过程，而是仅在受修改影响的段上执行，而对于修改影响的段，由编译获得的对象程序或在优化过程中可用的中间代码被重用。在优化的几个阶段，记录优化的中间结果，其中在重新编译时，使用在上述编译中获得的优化的中间结果直到不改变影响的阶段。因此，即使不能利用对象程序，也可以减少优化涉及的处理量。在实施本发明的方式中，不仅记录优化的中期结果，而且还记录优化的内容。在重新编译时，可以通过利用所存储的内容来快速执行在前面的编译中执行的要再次执行的优化处理的处理。可以显着降低执行重新执行优化处理所花费的时间。

摘要： The present invention relates to a storage system including a de-duplicate function and a full-text search function or the like, and reduces an amount of index information about full-test search to save storage resource. In this system, a storage apparatus includes a processing unit for de-duplicating a plurality of files having the same content regarding a file group of data inputted/outputted through a host apparatus. A full-text search processing server performs a full-text search processing to the file group and includes a processing unit for causing the full-text search processing to correspond to de-duplicate. An index information creation processing performed to a plurality of target files having the same content by the full-text search processing unit is inhibited according to a status of de-duplicate to the file group by the processing unit. Thereby, the amount of index information can be reduced.
