摘要： A closed rotary compressor includes a generally cylindrical sealed vessel having an oil sump defined therein for accommodating a quantity of lubricating oil, a drive unit housed within the sealed vessel and having a drive motor and a shaft driven by the drive motor, and a compressor mechanism housed within the sealed vessel. The compressor mechanism is provided with at least one set of compression elements. This set of compression elements is made up of a cylinder having a compression compartment and a refrigerant intake port both defined therein in communication with each other, first and second bearings secured to the lower and upper end surfaces of the cylinder, respectively, for rotatably supporting the shaft, a crank provided on the shaft for rotation together therewith, a ring-shaped roller encircling the crank and capable of undergoing a planetary motion in contact with the crank during rotation of the crank, and a radial vane slidably accommodated in the cylinder for reciprocating movement in a direction radially of the cylinder. The radial vane has a radial inner end held in sliding contact with an outer peripheral surface of the ring-shaped roller, to thereby divide the compression compartment into a suction chamber and a compression chamber. An oil passage is provided in the compressor mechanism to place the oil sump in communication with the refrigerant intake port. The oil passage has a throttled portion at a location adjacent to the refrigerant intake port.

摘要： In a hermetic type compressor, a sliding part (11) between a main shaft (4) and a lower end plate (8) is large in wear, and it is not allowed to operate stably for a long period. By communicating between the sliding part (11) and an oil feed pump (9) through an oil feed port (12), refrigerating machine oil (2) is supplied by force into the sliding part (11), and hence the lubrication is improved and the reliability is enhanced. In particular, it is preferably applied to the hermetic type compressor using HFC derivative refrigerants.

摘要： A database management system (DBMS) manages a database existing in a second storage device with an access speed lower than that of a first storage device. In an execution of a query, the DBMS dynamically generates tasks two or more executable tasks in parallel. The DBMS generates task start information which is information representing a content of the execution of the task, manages the task start information, and executes a content represented by the task start information by the task. The task start information includes a data address set existing in the second storage device. The DBMS controls movement of the data address sets between the first storage device and the second storage device based on a management state of the task start information. In addition, the DBMS selects the task start information based on whether or not the data address set exists in the first storage device.

摘要： Provided is a database system in which sorting of query results is sped up. The database system stores storage location information in which storage locations of the pieces of data are recorded in a given order. When there is no second task, which is executed based on data that is fetched in a first task, whether every piece of data requested in a third task, which is executed before the first task, has been fetched is determined. In the case where every piece of data requested in the third task has been fetched, data fetched in the first task is output. In the case where some of the data requested in the third task has not been fetched, data fetched in the first task is kept in a temporary buffer until every piece of data requested in the third task is fetched, and then output.

摘要： Provided is a backup method including a step (S1) of reading a log which is a data update difference, and identifying a data storage area (page) of backup data, a step (S2) of determining high/low reusability of the identified data storage area, a step (S3) of storing a log corresponding to a data storage area determined to be low in reusability in a log storage area preset on a memory, and a step (S4) of applying a log corresponding to a data storage area determined to be high in reusability to the identified data storage area in a cache area set on the memory, and updating the data storage area. Thus, by further reducing the number of I/O times in an external storage system of a standby system which backs up data by log transfer, it is possible to reduce introduction costs of a backup system and its normal-time operation's costs at normal times.

摘要： Provided is a technique of setting up a disaster recovery system. In a log-based disaster recovery system including a first site for processing data and a second site for storing a backup of the first site, the first site has a volume where data is stored and a volume that is made quiescent. The disaster recovery system accepts data updates while sequentially copying initial data from the quiescent volume to the second site. A copy of a log of the first site is kept in the second site and is synchronized with the original log. When data of the first site is updated and corresponding initial data has not been copied to the second site, the data to be updated is preferentially copied to the second site. A log is applied to the copied data, thereby matching data of the second site with data of the first site.

摘要： A recovery of a secondary DB is executed by a log including a update difference of a primary DB, and a command is executed by adding the command to the log and analyzing the log by a secondary site. An operation command execution in the secondary site is applied to the DB having the consistency in the transaction at the same timing as a primary site or an intended timing, by transferring and executing the operation command via the log. In the case that the command is constituted by a snap shot generating instruction, a plurality of volumes of a mirror set forming a secondary storage apparatus are set to a pair state and the secondary DB is written in each of the volumes and synchronized, and the mirror set is set to a split state after the synchronization is finished, whereby a secondary DB is stored.
