Abstract:
A technique for implementing policy-aware backup and restore capability in a tiered storage system. If a data set's contents are backed up from the tiered storage system to a backup storage system, metadata for the data set may also be backed up. Prior to the data set being restored from the backup storage system to the tiered storage system, the backed up metadata is restored and processed to determine a tier among the tiered storage pools to which the data set will be restored.
Abstract:
PROBLEM TO BE SOLVED: To efficiently use usable resources by allowing a distributing means to make a reservation by a publication-side distribution agent data processing unit and perform reception by a subscription-side distribution agent data processing unit or a subscriber application. SOLUTION: When a publisher 11 publishes a stock market message to a stream stock, the publisher 11 generates an RPC(remote procedure) call to the route distribution agent 21 of the highest level of broker tree structure. By this RPC call, a subscription request for the stream stock by a subscriber 32 is shown through the leaflet distribution agent of the lowest level. Namely, the data message of the publisher 11 is transmitted to the subscriber 32 through a downstream route distribution agent 21, and then an arbitrary intermediate distribution agent 22 and a leaflet distribution agent 24.
Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method for transmitting new constitution data from a system manager to each distribution agent in a broker with the minimum effort on the side of system manager and to provide a program product. SOLUTION: An issue and read data processing broker device 2 is provided with a means for receiving a data message issued on a theme specification stream from an issuer application corresponding to this issuer application and a means for distributing the received issue data message to reader applications 31-34 requesting the reception of the message on the stream of issuing the issue message and one of streams is secured for a managing message for describing the constitution change of the broker device.

Abstract:
A publish/subscribe data processing broker apparatus has: a means for receiving from a publisher application data messages published on a subject-specific stream b y the publisher application; and a means for distributing the received published data messag es to a subscriber application which has requested to receive messages on the stream upon which the published messages were published, the means for distributing including a plurality of connected distribution agent data processing units; wherein one of the streams is reserved for messages published by a publishing distribution agent data processing unit and intended for receipt by a subscribing distribution agent data processing unit located adjacent the publishing distribution agent data processing unit or intended for receipt by a subscriber application located adjacent the publishing distribution agent data processing unit.
