摘要:
In a data processing environment, data is replicated to a remote or secondary storage device in a manner which reduces the adverse performance effects and inefficient bandwidth usage imposed by the conventional one-transaction-at-a-time process. Transactions to be transferred are grouped by a replication manager by selecting transactions having start times earlier than the completion time of a first transaction. Thus, no transaction in a group will be dependent upon any other transaction in the group. Once selected, all transactions in the group may then be transferred to the secondary storage device.
