Abstract: Each time the file access request is received, it is discriminated whether there is an ACL which corresponds with the file system of the type following the switching in the file designated by the file access request. In cases where the judgment result is that there is no such ACL, an ACL which corresponds with the file system of the type following the switching is generated on the basis of an ACL which corresponds with the file system of the type prior to the switching which is associated with the designated file, and the ACL thus generated is used to control access in accordance with the received file access request.

Abstract: This invention provides a method involving the use of a non-ammonia-based deNOx catalyst for reducing the amount of NOx in exhaust combustion gas discharged from a boiler and an internal-combustion engine, wherein NOx and CO contained in exhaust gas are allowed to selectively react to reduce and remove NOx. This method involves the use of a catalyst comprising a cerium-zirconium composite oxide with Au supported thereon or a catalyst comprising a cerium-oxide-containing porous carrier with zirconium and Au supported thereon. Use of such catalyst enables purification of NOx and CO in exhaust gas and also enables generation of hydrogen.

Abstract: Provided is a computer system including a first server and a storage system. In the first server, a first virtual server and a second virtual server are operated. Upon reception of a request to boot the first virtual server, the second virtual server judges whether system software of the first virtual server, which is requested to be booted, matches system software of the first server in which the first virtual server is operated. In the case where the system software of the first virtual server and the system software of the first server do not match, the second virtual server updates the system software of the first virtual server before booting the first virtual server.

Abstract: A Java applet program loaded initially from a remote server is configured to receive additional user annotations for data displayed in an already opened applet window located at the user's client system. To increase the usefulness and flexibility of such program, the user is permitted to preserve/capture, during an interactive session, the modified applet window containing any such input or modifications to the applet window data. Because the updated applet window data cannot be written to the user's client system, however, (due to security restrictions), the present invention instead causes such modified window data to be converted to a standard compressed graphics file format (such as GIF for an image file for example), and then uploaded to the remote server. From there the applet can then open another applet window within a browser program pointing to the location of such file on the remote server. At that point, the user can then perform any desired operation on the file (i.e.

Abstract: In a data processing system in which main and sub disk storage devices are under the control of individual each disk control devices, the write processing time is reduced by selectively sending data according to the command-chaining time between main and sub disk control devices. A section for judging cable length and function of the sub disk control device 36 estimates command-chaining time between a pair of main and sub disk storage devices. The channel command analyzing section 31 estimates the number of records to be transferred and the length of a record using a LOCATE RECORD command. The command judgment section for the sub disk control device 32 optimizes the command-chain to be issued to the sub disk control device using the above-mentioned information. Then, the section for issuing command to the sub disk control device 35 issues the optimized command chain. Thus, a shorter transmission time is realized by either sending individual records or an entire track of data.
