Claim:
A method of processing a transaction in a system wherein at least first and second information processing devices are linked to perform transaction processings and utilize standard identifiers (IDs) for identifying related transaction processings, the method comprising steps of: generating a standard ID for processing of the transaction in the first information processing device; storing in a mapping table in each of the first and second information processing devices to be involved in the processing of the transaction, each of the mapping tables holding a record for the processing of the transaction for a predetermined period of time and a local ID for processing the transaction in each of the first and second information processing devices, each of the local IDs corresponding to the standard ID for processing the transaction; sending an inquiry from the first information processing device to the second information processing device, the inquiry using the standard ID to identify the processing of the transaction; receiving from the second information processing device, the local ID for processing the transaction of the second information processing device; and relating the received local ID for processing the transaction of the second information processing device with a respective local ID for processing the transaction of the first information processing device which has sent the inquiry, wherein a value of the predetermined period of time for holding said record is modified depending upon whether the information processing device which makes a transaction processing request is the first information processing device which has sent the inquiry.
