SYSTEM AND METHOD FOR LOGGING TRANSACTION RECORDS IN A COMPUTER SYSTEM

摘要

An improved method and system for logging transaction records in a computer system. The method may include writing a confirmation log record to the log file for a transaction that completes normally, and not writing a confirmation log record for transactions that are aborted. The log file may be unloaded periodically by an unload program. The unload program may write transaction log records accompanied by a confirmation log record to a good output file and transaction log records not accompanied by a confirmation log record to a suspended output file. On a subsequent execution, the unload program may combine the log records in the log file and the suspended file. The unload program may write transaction log records accompanied by a confirmation log record to a good output file. The unload program may write transaction log records not accompanied by a confirmation log record and which have not exceeded a transaction time limit to a suspended output file. The unload program may write transaction log records not accompanied by a confirmation log record and which have exceeded a transaction time limit to a disposal output file. The transaction log records in the good output file may then be processed normally by log processing programs.
