Abstract: Examples of a no rollback threshold for an audit trail are disclosed. In one example implementation according to aspects of the present disclosure, a method may include processing, by a computing system, a database transaction, and determining, by the computing system, whether a transaction span of the transaction exceeds a no rollback threshold for an audit trail. The method may include, in response to determining that the transaction span exceeds the no rollback threshold, converting, by the computing system, the transaction into a no rollback transaction. Additionally, the method may include, in response to determining that the transaction span exceeds the no rollback threshold, abandoning, by the computing system, the transaction if an error is encountered during the processing the transaction.

Abstract: A method for transaction registration is described herein. The method includes sending, for a transaction manager, a registration request for a transaction. The method also performing data accesses on a data server. The registration request is non-blocking to the data accesses. The method further includes performing a two-phase commit process for the data server if the registration request is accepted. Additionally, the method includes handling the rollback if the transaction registration is rejected.

Abstract: A plurality of transaction domains include transaction managers owning respective transactions, where a first of the transactions is uniquely identified by a unique identifier that indicates a first of the transaction managers that owns the first transaction, the unique identifier relating to the transaction domain in which the first transaction manager is included. The first transaction manager receives a request from a requester that initiated the first transaction, the request sent to the first transaction manager based on the unique identifier of the first transaction.

Abstract: One embodiment is a method that reads audit from an audit trail of a source database distributed across multiple storage systems with independent audit trails and then replicates the audit trail to a target database distributed across multiple storage systems with independent audit trails without manual coordination by a database administrator.

Abstract: One embodiment is a method that builds a target database with transaction logs from an online source database. The transaction logs include both existing data in the source database and updates that occur to the source database while the target database is being built.
