PROBLEM TO BE SOLVED: To prevent a system from stopping due to the shortage of a log recording region due to logging that is generated during data loading. SOLUTION: The amount of log that is generated during the execution of a data load program 24 is estimated from an input data file 42 for recording added data, and the processing of the data load program 24 is completed when there is not any sufficient free space after comparing with the free space of a log file 32. The free space of the log file 32 is monitored during the addition of data, and transaction for adding data is settled when there are no sufficient regions for recording a log, thus suspending processing for loading data. After the supervisor of a database management apparatus secures the free space of the log file 32, the data load program 24 is executed again, and data addition processing is resumed.
