摘要： Database operation records are sequentially read from two or more log files. If the transaction identifier is new and the record is not an end-of-transaction record, an open transactions list entry is created. If the transaction identifier is new and the record is an end-of-transaction record, a transaction type list entry is created or updated. If the transaction identifier is not new and is not an end-of-transaction record, an open transactions list entry is updated. If the transaction identifier is not new and the record is an end-of-transaction record, a transaction type list entry is created or updated. When all log file records are read, analytical comparison between the information associated with two or more of the log files in data fields in the transaction type list entries is performed.

摘要： 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.

摘要： A log file contains operation records, each operation record is of a certain type, and each operation record is associated with a transaction. A plurality of operation records is read from the log file into a record store. Records of the plurality of operation records of each operation record type are sampled at a predefined sampling rate. Operation records in the plurality of operations records are identified that are associated with completed transactions of which the sampled operation records are associated. The identified operation records are then extracted from the record store into a data store.

摘要： A method for identifying matching transactions between two log files where each transaction includes one or more statements. Each log file record records the execution of a statement and includes a transaction identifier. Each record in turn in one log file is compared to an advancing window of records in the other log file. A first table contains associations of statements to transactions and transactions to statements for records in the window. If a match is found between a record in the one file and a record in the window, information associating partial transactions in the one file to potential transactions of the records in the window is added to a second table. If an end-of-transaction record is read from the one file, a best match is found between the ended transaction and the potential transactions based on information in the first and second tables.

摘要： A predefined number of matches is identified between records in a first file and records in a second file. For the matches, determine the span of the actual range of record positions in the second file relative to the positions of the operation records in the first file within which all matches were found. If the actual span is smaller than the span of a current defined range of record positions by at least a first threshold value, decrease the span of the current defined range. If the actual span is within a second threshold value of the span of the current defined range, increase the span of the current defined range. If an amount above a third threshold value of operation records in the first file are not matched to operation records in the second file, increasing the span of the current defined range.
摘要翻译：在第一个文件中的记录之间识别预定义数量的匹配，并记录在第二个文件中。对于匹配，确定第二个文件中相对于找到所有匹配的第一个文件中的操作记录的位置的实际记录位置范围的跨度。如果实际跨度小于当前定义的记录位置范围至少第一阈值的跨度，则减小当前限定范围的跨度。如果实际跨度在当前限定范围的跨度的第二个阈值内，则增加当前定义范围的跨度。如果第一文件中的操作记录的第三阈值以上的量与第二文件中的操作记录不匹配，则增加当前定义范围的跨度。
