US 2014/0279945 A1 · MATCHING TRANSACTIONS IN MULTI-LEVEL RECORDS

Abstract

Identifying matching transactions. First and second log files contain operation records of transactions in a transaction workload, each file recording a respective execution of the transaction workload, the method comprising. A first record location in the first file and an associated window of a defined number of sequential second record locations in the second file are advanced one record location at a time. Whether each operation record of a complete transaction at a first record location has a matching operation record at one of the record locations in the associated window of second record locations is determined. If so, the complete transaction in the first file and the transaction that includes the matching operation records in the second file are identified as matching transactions.

Dependent claims

A method for identifying matching transactions, first and second log files contain operation records of transactions in a transaction workload, each file recording a respective execution of the transaction workload, the method comprising:

advancing one record location at a time, by a computer, a first record location in the first file and an associated window of a defined number of sequential second record locations in the second file;
determining, by the computer, whether each operation record of a complete transaction at a first record location has a matching operation record at one of the record locations in the associated window of second record locations;
in response to determining that each operation record of a complete transaction at a first record location has a matching operation record in the associated window of second record locations, identifying, by the computer, the complete transaction in the first file and the transaction that includes the matching operation records in the second file as matching transactions.

A computer program product for identifying matching transactions, first and second log files contain operation records of transactions in a transaction workload, each file recording a respective execution of the transaction workload, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

advance, one record location at a time, a first record location in the first file, and a window of a defined number of sequential second record locations in the second file;
determine whether each operation record of a complete transaction at a first record location has a matching operation record at one of the record locations in the associated window of second record locations;
in response to determining that each operation record of a complete transaction at a first record location has a matching operation record in the associated window of second record locations, to identify the complete transaction in the first file and the transaction that includes the matching operation records in the second file as matching transactions.

A computer system for identifying matching transactions, first and second log files contain operation records of transactions in a transaction workload, each file recording a respective execution of the transaction workload, the computer system comprising:

a computer-readable storage medium having computer instructions embodied therewith, and a processor executing the computer instructions to cause the computer system to:
advance, one record location at a time, a first record location in the first file, and a window of a defined number of sequential second record locations in the second file;
determine whether each operation record of a complete transaction at a first record location has a matching operation record at one of the record locations in the associated window of second record locations;
in response to determining that each operation record of a complete transaction at a first record location has a matching operation record in the associated window of second record locations, to identify the complete transaction in the first file and the transaction that includes the matching operation records in the second file as matching transactions.
