Abstract: Utilizing only a single input/output (I/O) session to commit a single message transaction to a non-volatile storage within a message transaction system is disclosed. In one embodiment, a method first determines an error detection value, such as a checksum, for a single transaction. The single transaction and the value are written to the non-volatile storage in only a single I/O session. The single transaction is committed upon the successful writing of the transaction and the error detection value to the storage. Upon recovery from a system failure, the error detection value for the transaction is redetermined; if it does not match the value as has been stored to the storage, then the transaction is aborted. Otherwise, the transaction has been committed.
