Abstract: Managing a log-full condition of a transaction log in a transaction processing system, where the transaction log has a plurality of log records each associated with a particular transaction. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A dynamic transaction backout of the identified transaction is initiated, with the writing of a backout record for the identified transaction to the log being delayed. Confirmation that the backout has completed is awaited before trimming the log. Then the delayed backout record for the identified transaction is written to the log, and normal logging is resumed.

An amount of memory allocated to a container is dynamic. A set of the containers can be selected for a file system consistency check. The file system consistency check is performed on only the set of the containers instead of on the entire file system.

Abstract: A file system watcher in the presence of different file systems to allow synchronization of replicated files distributed among different file systems without compromising the features of each file system is described. To synchronize the distributed replications, a platform independent synchronization manager creates a file system watcher for each file system associated with a replication of the file. The file system watcher monitors each object for events affecting the object or the object's constituent files, such as creation, deletion, change and rename. Notifications are sent to the synchronization manager, which consolidates the modifications and updates a locally stored replication, if necessary. The synchronization manager then sends a notification of an update to other synchronization managers for replications of the distributed file or folder.

Abstract: Some embodiments provide methods and apparatuses for performing a near-instantaneous restore of a database. During operation, the system intercepts a database management system restore request to restore a database from a backup file to a data file, wherein the backup file comprises a first number (e.g., N1) of data pages. Next, in response to intercepting the database management system restore request, the system sends information to the database management system indicating that the backup file comprises a second number (e.g., N2) of data pages, wherein the second number of data pages is less than the first number of data pages (e.g., N2<N1). Once the database management system has copied the fewer number of data pages from the backup file to the data file, the database management system may indicate that the restore is complete, and continue processing database requests as if the database management system was back online.

Abstract: The present invention relates to a system and method of data restoration, for instance, after the occurrence of a user error. In particular, snapshot database can be maintained that stores a copy of database data. The snapshot database does not have to store a complete copy of all data on a source database, but rather shares data that is common to both but not necessarily identical. If an error occurs on the primary database then the database can be reverted back to a point in time prior to the error by replacing source database files with snapshot files. Additionally, an undo component can be employed in conjunction with the snapshot to approach an error to a finer grained point in time. In brief, the present invention can restore a database much faster and simpler, while utilizing less space and resources than conventional data restoration technologies.

Abstract: Each file is assigned in advance with a WWUID which is newly assigned to a file upon the creation or update of the file and is inherited from a file to a copied file when the file is copied. In a backup apparatus, a file name reception unit receives the file name of a backup target file. A WWUID reception unit receives a WWUID corresponding to the file name. A WWUID search unit searches for the same WWUID in backup management information of a previous day stored in a backup destination. Only if the search is failed, a file operation instruction unit instructs the storing of the backup target file into the backup destination. Then, an Rcnt update instruction unit instructs the updating of the number of references made to the WWUID within the backup destination. A second management information update instruction unit then instructs the updating of backup management information of the current day.

A user is therefore able to obtain database resources from an Internet Database Service Provider (IDSP) without incurring the full costs of database administrator(s), dedicated database equipment facilit(ies), or even dedicated database device(s), depending on usage. Meanwhile, the IDSP incurs minimum staffing loads because of self-service tools. Costing model and automatic billing are also described.

During the upgrade of the farms, requests may continue to be processed by the farms. The farms may be automatically load balanced during an upgrade. As content becomes available on the new farm, requests for the content may be automatically redirected to the new farm.

Abstract: A system and method for performing a granular restore operation of a database from a differential backup of the database. A bitmask is created during a differential backup and stored with the differential backup file. When a user requests a granular restore operation, views of how the database existed at different points of time may be presented to the user. The objects the user wishes to restore may be selected from one of the views. Next, the bitmask may be read to determine if the objects should be retrieved from the differential backup file or a full backup file. Finally, the objects may be restored to the database from the proper file.

Abstract: An “operate with missing region” feature of this disclosure allows the cluster to continue servicing reads for available regions even when some regions are missing. In particular, upon a given node failure condition, the cluster is placed in an effective read-only mode for all regions. The node failure condition typically is one where there has been a failure of an authoritative region copy and no backup copy is then available. As used herein, “read-only” means that no client write or update requests will succeed while the cluster is in this state. In particular, those requests should fail with an error message (or the like) that indicates failure because of the read-only status. Preferably, such requests are then re-tried. In this mode, all regions are only allowed to perform read operations. During the read-only state, the cluster continues to operate with missing regions, and missing regions are entered on the region map.
