    摘要： A process for producing 2,6-naphthalene dicarboxlic acid which comprises oxidizing a 2-alkyl-6-acyl naphthalene with molecular oxygen-containing gas in the presence of a catalyst containing cobalt, manganese and bromine in an acetic acid solvent, characterized in that the oxygen concentration in the exhaust gas is controlled so as to satisfy the following equation:15/(X+7.5)+0.1.ltoreq.Y.ltoreq.90/(X+8)+0.4 (1)wherein Y is oxygen concentration (volume %) in the exhaust gas and X (cm) is a distance between the inlet for an oxygen gas and the surface of the reaction solution in a static state, and the catalyst further contains an aromatic acid in which at least two carboxylic acid groups are in an orthposition or its precursor as a co-catalyst, and that part of all of the mother liquor from which the 2,6-naphthalene dicarboxylic acid crystal has been separated is cooled to remove the precipitated impurities, and thereafter is reused in the oxidation reaction, is disclosed.

    摘要： A snapshot volume is migrated by using a primary volume of a migration destination storage apparatus.The management server comprises a controller for generational management, by means of the snapshot volumes, of differential data for the logical volume which is the parent volume of the snapshot volume, and, if an instruction to copy a snapshot volume of a designated generation is received and a snapshot volume prior to the designated generation of the copy instruction-target snapshot volume exists, the controller copies the differential data between the designated-generation snapshot volume and the existing snapshot volume, and associates the copied differential data with the existing snapshot volume.

    摘要： A storage system capable of identifying all volumes to be audited is provided.Operation logs 3005 concerning the operations of volumes are associated with a time and stored in storage apparatuses 1400 and 1500, and a management computer 1100 collects information about these operation logs 3005, restores the status history of the operation logs 3005, sets, as an audit range, the operation logs 3005 including volumes with an audit period and audit target data stored therein, extracts the operation logs 3005 belonging to the audit range from the restored status history of the operation logs 3005, and transmits the extracted operation logs 3005 to a computer (requesting computer) 1000. As a result, all the audit target volumes can be identified.
