摘要： An automatic initial data load to a new table copy concurrently with active replication to existing table copies in an asynchronous replication group includes: initiating a data load of the new table copy; creating spill queue(s) at the new table copy; loading the data from a source table copy to the new table copy, where changes for the active table copies are applied during the loading, but changes to the new table copy are stored in a spill storage area; applying the changes in the spill storage area to the new table copy after the loading of the data is done; and removing the spill storage area after the changes have been applied to the new table copy. Thus, a new table copy is initialized into the replication group without requiring that replication be suspended at the source or any of the existing table copies during the initializing process.

摘要： A mechanism for handling transaction messages in asynchronous data replication in a database system, in which the database system includes a source node and a target node, and each transaction message has information concerning a row change to a table copy at the source node. The mechanism determines whether a first transaction message has a dependency on a preceding non-completed transaction message. Responsive to the first transaction message having a dependency on the preceding non-completed transaction, the mechanism holds the first transaction message, completes the preceding non-completed transaction message including applying the row change associated with the preceding non-completed transaction message to the table copy at the target node, and responsive to completing the preceding non-completed transaction message, releases the first transaction message and applying the row change associated with the first transaction message to the table copy at the target node.

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： An improved method for providing parallel apply in asynchronous data replication in a database system is disclosed. The improved method and system 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 method and system 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 method and system requires significantly less overhead than conventional approaches.

摘要： Techniques for initializing a connection in a peer-to-peer database replication environment. A message is received from an initiator node, indicating that the initiator node will begin replicating changes made to a particular data entity. One or more replicated changes relating to the database entity are received from the initiator node. If an updated instance of the data entity does not currently exist on a target node then one or more load operations are performed to create the updated instance. The stored replicated changes may then be processed against the updated instance of the database entity.

摘要： Provided are a method, system and program for batching transactions to apply to a database. A transaction manager receives a plurality of transactions to apply to a database and adds the transactions to a work queue. One of a plurality of agents processes a batch of transactions from the work queue. Each agent executes a batch of transactions from the work queue against the database independent of the operations of other of the agents executing batches of transactions. The agent applies the transactions in the batch against the database and commits the transactions in the batch to the database in response to completing all of the transactions.
