DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file utilization output / monitoring device, and more particularly, to a file utilization output / monitoring device for outputting an actual utilization value which is used as a reference when estimating a file capacity.

[0002]

2. Description of the Related Art Conventionally, a person uses a utility or the like at an arbitrary timing to check the usage rate at that time.

[0003]

In the conventional method, the usage rate must be periodically checked manually.

In order to estimate the file capacity more accurately, it is very effective to measure the maximum value of the actual usage. However, the usage rate of the file changes every moment due to the movement of the job, the degree of multiplicity, and the like. In addition, unusual days (eg:
It is anticipated that the usage rate of the file will greatly change, for example, the interest settlement date in the banking business) as compared to general days. Since the maximum value of the file usage varies depending on the time or the day, the file usage measurer needs to measure the frequency frequently and manually over several days or on special days, which is very inefficient. It is troublesome work.

[0005]

According to the present invention, there is provided a file utilization output / monitoring device comprising: an interval time (21) for designating a file utilization monitoring interval; a reference utilization (22) for designating a file utilization monitoring standard; A data input means (11) for inputting a file name (23) for designating a file usage monitoring target file; and a target file (24)
File information obtaining means (12) for obtaining information on the space use status of the above, and a file usage rate is calculated from the information obtained by the file information obtaining means, and the information is edited and output to an output area (25). If the file usage rate at the time is greater than the reference usage rate, a message to that effect is output to the console, and the previous usage rate is calculated according to the calculated usage rate.
Data output means (1) for changing the interval time
3), a timer means (14) for holding the time specified by the interval time, a file use list and a maximum file capacity (maximum sub-capacity at a certain time interval) from the file information stored in the output area. Book table output means (15) for outputting a total value of file capacity).

[0006]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The data input means 11 receives as input data
An interval time 21 indicating a time interval for monitoring a file usage rate, a reference usage rate 22 indicating a reference value of a notification message output, and a file name 23 indicating a file usage rate output / monitoring target file name are obtained.

[0008] The file information obtaining means 12 includes a file space amount, a directory area amount, a logical track size, a data area amount, a used area amount, and directory overflow information as information on the space status of the target file 24 designated by the file name 23. , The number of blocks per track, the block size, and the return code are obtained using a system macro.

The data output means 13 calculates a file usage rate from the data area and the busy area obtained by the file information obtaining means 12, edits the information, and outputs the information to the output area 25.

If the file usage rate at this time is larger than the reference usage rate 22,
This is output to the console 26 to alert the user.

The timer means 14 has an interval time 2
Hold for the time specified in 1.

After the waiting in the timer means 14, the processing shifts to the file information obtaining means 12 again, and a series of these processing is repeated.

The book table output means 15 outputs a file usage status list from the file information stored in the output area 25. Further, the book table output unit 15 outputs the maximum file capacity, which is the sum of the maximum sub-file capacities at the specified fixed time interval.

Next, the operation of the embodiment shown in FIG. 1 will be specifically described using an example of processing data.

Input data is interval time = 600
(Unit: seconds), reference material rate = 70 (%), file name =
FILE. ABC. In this case, the data output means 13
Is the target file FILE. Obtained by the file information obtaining means 12. The file usage rate is calculated from the information on the space usage status of ABC, and the file information is output to the output area 2
5 is output. If the file usage rate at this time is smaller than the reference usage rate of 70% (in the case of A in FIG. 2), the processing shifts to the timer means 14 and waits for 10 minutes (= 600 seconds). When the file usage rate at this time is 70% or more, which is the reference usage rate, (B, FIG.
(C, D) outputs a notification message to the console. When the file usage rate is 80% or more (C in FIG. 2), the monitoring interval is shortened to 5 minutes and the file capacity is monitored. When the file usage rate is 90% or more (D in FIG. 2), the monitoring interval is reduced to 3 minutes and the file capacity monitoring is continued.

When the file usage rate becomes smaller than 80%, the monitoring interval returns to the value specified by the in-interval time (= 10 minutes).

After monitoring, the book table output means 15 outputs the output area 2
5 to edit the file information and output a file usage status list. In addition, the maximum value of the sub-file at a specified fixed time interval (for example, 30 minutes) is searched, and the total value is obtained. Explaining with the example of FIG.
At 0:10, the file usage is 35, which is the maximum. However, from 10:10 to 10:30, 3
Looking at the maximum value of each subfile in 0 minutes, a1: 20,
a2: 5, b1: 20, c2: 5, which is 50 in total. In other words, the maximum usage of the file may be 50 depending on the movement of the job. If the file capacity is estimated based on the total value 50, the operation conditions such as the job operation conditions and the multiplicity can be obtained. Even if the maximum file capacity changes depending on the environment, a sufficient capacity can be secured.

[0018]

As described above, according to the present invention, the usage rate of a specified file is measured and monitored at regular time intervals, and the information is output.

The file usage monitoring mechanism (notification message output from the data output means 13) allows the operator to know in advance the files at risk of overflow. Therefore, it is possible to stop the start of a job that uses the file and take measures such as file expansion.

When the usage rate of the file is high, the monitoring time is shortened, and a more accurate file capacity estimation can be performed.

From the file usage status table, the operator can know the file usage rate that changes every moment with little trouble for the operator, and can estimate the capacity more accurately. .

Further, in the present invention, since the maximum subfile capacity in the peak time period of the file usage rate is totaled and the information is provided, it is necessary to take measures such as securing a sufficient capacity in advance based on the information. , Job operating conditions,
Even when the maximum file capacity changes due to the operating environment such as the degree of multiplicity, stable operation of the system can be ensured without abnormal termination of the job due to file overflow.
