of the filed signal will be identical with its content when it was created and this does not include any information about the current transaction b failure in order to provoke work that depends upon this transaction b failure the memory signal is modified to record the failure and start a u2018 failure transaction u2019 c 302 to perform work that records the failure in the present embodiment the memory signal also records further information about the failure such as error codes and messages the failure transaction c is started synchronously with the backout processing 303 of the work transaction the memory signal is not discarded but passed 304 to the failure transaction c for further processing the work transaction is suspended 305 after the recoverable file backout processing is finished and before backout processing is finished when the work transaction is resumed 307 by the failure transaction it can terminate 308 and conclude the syncpoint processing in the normal way while the work transaction is suspended failure transaction c starts by logging 306 the modified memory signal that is creating a logged signal which is a copy of the memory signal in the transaction recovery log so that it can survive system failures this behaviour is similar to that of the consume processing.
