After this, primary processor 11 is set as new journal file Fn (step S55) with the current journal file that is stored in the auxiliary storage device 13.For example, may be deposited storer 12 temporarily or be stored into certain title is in the auxiliary storage device 13 about the information of new journal file Fn, such as be " temporary ", catalogue under.
The former days daily record data of will file Fo and the daily record data of the new journal file Fn that in step S55, is provided with that primary processor 11 relatively is provided with in step S45 subsequently, thereby the daily record data of determining the journal file that is compared whether different (step S60).When former days will file Fo and new journal file Fn when having no difference, check up to current gate time T (step S70), then with preset time T s, for example 5 seconds, relatively (step S80).
When determining that in step S80 T does not surpass preset time T s between institute's timing, the control program execution in step S100 of primary processor 11.Otherwise, when T between institute's timing surpasses preset time T s, T be reset (step S90) between institute's timing.After the time was reset, primary processor 11 checked whether the keeper wants closing server computing machine 10 (step 100).When the result who checks determined that server computer 10 is not selected to shut down, control program was got back to step S40 T computing time.
When will file Fo and new journal file Fn daily record data were different on the former days determining in step S60, primary processor 11 was checked up to current gate time T (step S110), compares supervision time T of institute and preset time T s (step S120) then.
When determining that in step S120 T does not surpass preset time T s between institute's timing, the control program execution in step S100 of primary processor 11.Otherwise when T between institute's timing surpassed preset time T s, primary processor 11 was created journal file Fm, was stored in only to allow by daily record data memory device 30 and write down therein in the recording medium of a secondary data (step S130).
When former days will file and new journal file daily record data when different, newly create a daily record data that had both comprised precedence record, comprise and the previous file of the different daily record data of daily record data will file on the former days of covering again.Final journal file is stored in auxiliary storage device 13.Otherwise, but the journal file Fm that is stored in the single write record medium only writes down the daily record data of change.
For example, when former days the will file comprise the data of creating during this period of time from certain time point to 2000 13:20:00 in 9, on Mays, and the new daily record data that changes comprises that from May 9,13:20:05 to 2000 year on the 9th May in 2000 during data that 13:20:50 creates during this period of time, all are all deposited in the journal file of auxiliary storage device 13 from daily record datas that this time point to 2000 13:20:50 in 9, on Mays creates.But, in this case, the daily record data that has only new change, i.e. the daily record data that 13:20:05 to 2000 year on the 9th May, May, 13:20:50 on the 9th was created when daily record data changes to some extent during this period of time in 2000, but be stored in single write record medium.
Therefore, auxiliary storage device 13 has only 1 journal file, but and has a plurality of journal file Fm, each file to set up when daily record data changes to some extent in the described single write record medium.In order to distinguish journal file Fm mutually, distributed sequence number separately for those journal files.
For example, in the time of each daily record data of record, but the filename that is stored in the journal file Fm in the single write record medium has added that respectively time point is as sequence number, adopt such form, for instance: " log-nov2-12-50-23.txt... "; " log-nov2-13-52-11.txt... ", " log-nov2-13-53-15.txt... " and " log-nov2-14-01-55.txt... ".Rely on such sequence number, not only can realize the simple identification of each journal file Fm, easily the time point of each daily record data of identification record.
After this, primary processor 11 will be sent to daily record data memory device 30 at the journal file Fm that step S130 creates by daily record data storage device access unit 15.But the journal file Fm that is sent to daily record data memory device 30 from daily record data storage device access unit 15 is deposited in single write record medium (step S140) by daily record data memory device 30.
