    摘要: A data item is retrieved from a data store in a data processing system. The data processing system comprises an index, which at least partially indexes the data store, and also a partiality definition store. The partiality definition store indicates a part of the data store which is referenced by the partial index. A request is received for a data item from the data store and responsive to determining that the requested data item is not referenced by the partial index, the data store is searched by using the partiality definition store to avoid searching a part of the data store which is known to be indexed.

    摘要: A computer readable medium encoded with a computer program for handling transaction messages in asynchronous data replication in a database system is disclosed. The computer program provides a high speed parallel apply of transactional changes to a target node such that the parallel nature of the application of changes does not compromise the integrity of the data. The computer program detects, tracks, and handles dependencies between transaction messages to be applied to the target node. If a transaction message has a dependency on one or more preceding transaction messages whose applications have not yet completed, that transaction message is held until the application completes. In addition, the computer program requires significantly less overhead than conventional approaches.

    摘要: Methods and apparatus for performing a data migration in a clustered computer system. In one aspect, the availability of the data being migrated is maintained during the migration. In another aspect, a data set is migrated by a transfer utility in one of the hosts in the cluster, and in response to a failure of the host, the migration is resumed without restarting from the beginning point of the data set. In a further embodiment, the hosts in the cluster have agents associated therewith to manage the data migration, and prior to taking at least one action associated with the data migration, the agents coordinate to ensure that the hosts in the cluster are prepared to have the at least one action taken.
