Rapid horizontal extending method for databases
ActiveCN102930062AImprove the speed of expansionEasy to monitorSpecial data processing applicationsData segmentDisk size
The invention discloses a rapid horizontal extending method for databases, which belongs to the field of data migration and storage. The method comprises the following steps: a monitoring and control system carries out monitoring on the disk storage space of the existing database, and when the disk size reaches a preset storage capacity threshold, the monitoring and control system triggers a hardware storage increasing action so as to make a hardware environment preparation for data migration; and a routing protocol carries out a modular computation on the instance number N of the current database according to a major key ID to be inserted currently, and routes the line number of data to be inserted into a specified database, and when the number of inserted lines exceeds a preset storage number threshold, the routing protocol triggers a database segmentation action so as to migrate specified data into a new database, thereby completing the rapid horizontal extending of the database. The method disclosed by the invention can be applied to disk databases or memory databases, and the method is easy to use and simple, and avoids the problem that hotspots are distributed nonuniformly caused by traditional horizontal extending of databases; in addition, as the scale of migration of data segmented each time is small, the extending speed is improved. In conclusion, the overall architecture meets the requirements on high availability, high reliability, high speed, high efficiency and the like.

Relocating bad block relocation (BBR) directory upon encountering physical media defect on a disk
Apparatus, method and program product for relocating Bad Block Relocation Directory (BBRD) on a disk storage pre-allocate a number of areas for BBRD in different locations of the disk storage. The locations for the BBRD are calculated based upon the size of the disk and BBRD count. If the update of BBRD fails due to defective media at the location to be updated, that location is abandon and the next pre-allocated location is used. A copy of the BBRD is stored in RAM and maintained by the kernel. By so doing, when a bad block in the BBRD is detected the kernel causes the BBRD to be written in a good one of the locations reserved for BBRD. When the number of alternate BBRD locations used hits a pre-defined threshold, this indicates a situation where many sections of the disk are going bad and the disk needs replacement. If all BBRD locations are used, the disk is presumed bad and all future I / O activities to the disk is suspended. An administrator may be notified that the disk is going bad and needs to be replaced.
