    摘要: Systems and methods for non-disruptive cache startup, shutdown, data partition movement, and node rebalancing for a data fabric within a data grid in a database environment. The data grid is a clustered in-memory database (IMDB) cache comprising one or more data fabrics including multiple IMDB cache nodes. The method takes a time tag and moves data from source to destination nodes while allowing updates to data on the source nodes. The method propagates updates occurring after the time tag to destination nodes from source nodes and switches applications and ownership to the destination nodes. Another method slices data for a partitioned fabric and stores slices on nodes. Another method starts a data fabric by moving data from a grid backend to the nodes. In an embodiment, another method rebalances nodes in a non-disruptive manner. When a fabric is shutdown, the method saves data from the nodes to the grid backend.

    摘要: Methods, systems, and computer program products are provided to efficiently allocate extremely large storage spaces for use by dynamic hash tables. A contiguous storage space is designated from which dynamic hash tables can be created. These dynamic hash tables benefit from rapid allocation by being able to reserve many allocation units (each potentially comprising a large number of pages, e.g., 256 pages) within a short span of time, rather than resorting to reserving individual pages. The efficiency from allocation and the contiguous space significantly improves performance for databases in the 50 GB-100 GB size range.

    摘要: Methods, systems, and computer program products are provided to manage a database system. The method includes locking during a database system idle time access by the database system to a data page of a data allocation unit, compressing during the database system idle time a data stored in the locked data page, and recording during the database system idle time an indication that the compressed and locked data page includes free storage space, wherein unlocked data pages of the data allocation unit are accessible by the database system during the compressing of the data stored in the locked data page. Thus, the data page may be compressed during idle time and the space freed therein may be used during a subsequent run time without the need for a reorganization of the data pages within the corresponding table (as in, for example, operation of a reorg+rebuild SQL command combination).

    摘要: System and methods for temporary data management in shared disk cluster configurations is described. In one embodiment, a method for managing temporary data storage comprises: creating a global temporary database accessible to all nodes of the cluster on shared storage; creating a local temporary database accessible to only a single node (owner node) of the cluster; providing failure recovery for the global temporary database without providing failure recovery for the local temporary database, so that changes to the global temporary database are transactionally recovered upon failure of a node; binding an application or database login to the local temporary database on the owner node for providing the application with local temporary storage when connected to the owner node; and storing temporary data used by the application or database login in the local temporary database without requiring use of write ahead logging for transactional recovery of the temporary data.

    摘要: The invention discloses a method for acquiring MBMS access information comprising: in a modification period, upon receiving an MBMS access information message transmitted from a network a UE initiating a corresponding procedure according to its state; if completing the corresponding procedure successfully, the UE stopping receiving a further MBMS access information messages; if not completing the corresponding procedure successfully the UE continuing acquiring further MBMS access information messages. The method facilitates the UE to automatically control MBMS access information acquiring procedure, and further reduces energy consumption of the UE to the maximum extent.
