[Problem to be Solved by the Invention] With respect to the conventional technology, the technology described in Japanese Patent Application Laid-Open No. 62-182822 prepares two schedule files including a job execution schedule table and a job procedure. A job execution schedule is changed based on the contents of the updated schedule file by inputting a switching command in which the contents of the other schedule file are updated while the file is being used. Thus, an attempt is made not to interrupt the automatic operation due to a change in the job execution schedule. The technology disclosed here seems to intend to define an execution start time of each job and to execute the job at the defined time to realize automatic operation. Here, the disclosed technology is a schedule of a job to be started to execute, and does not take into account the load status of the entire system. From the viewpoint of automatic operation of an electronic computer system (also referred to as an information processing system), it is important to save labor for the operator and to operate the electronic computer system properly under load. From this viewpoint, in the technique disclosed in Japanese Patent Application Laid-Open No. 62-182822, the driving operator must input a switching command, and it is difficult to achieve labor saving. Further, if the execution start of the job is controlled only depending on the time, it is difficult to realize a proper load operation when irregular jobs are mixed. In addition, batch processing jobs and time sharing systems (Time Sharing Sys
tem: TSS), there is no disclosure of a driving schedule method when conversation processing and online processing are mixed.

On the other hand, the technique disclosed in Japanese Patent Application Laid-Open No. Sho 62-174860 sets an allowable number of sessions so that the load on the computer system is not applied more than the limit, and processing is performed preferentially even if the number of sessions exceeds the allowable number. It attempts to allow sessions of the right nature, but does not mention how to determine the number of sessions allowed.

By the way, with the diversification and complexity of the use of computer systems, automatic operation that makes use of the empirical knowledge of the operator, when irregular jobs are mixed, batch processing, TSS processing, and online processing. There is a further demand for proper load operation and labor-saving operation in a mixed environment, and a method for automatically performing these operations remains as an issue.

Accordingly, an object of the present invention is to provide an operating device having a mechanism for constantly monitoring the load status of the system and automatically sending out appropriate operating parameters based on the load status in order to realize automatic operation of the computer system. Is to provide.

Another object of the present invention is to automatically change operating parameters when the load on the computer system is clearly different depending on the time period, such as during the daytime, at night, or on holidays, during operation of the computer system. It is an object of the present invention to provide an operating device provided with a mechanism for performing the above.

Another object of the present invention is to provide means for measuring a response time that matches a user's sense of use in order to achieve proper load operation of an electronic computer system.

Another object of the present invention is to provide a control means capable of immediately measuring the response time of each job and command such as batch processing and TSS processing, and storing the measured data in time series.

Another object of the present invention is to set the response time and processing time of each job of TSS processing, online processing, and batch processing as load conditions when selecting appropriate operation parameters based on load conditions. It is an object of the present invention to provide a driving support control unit that uses a load condition that matches a user's sense of use as a criterion.

Another object of the present invention is to guarantee the response time of the TSS processing and the online processing when selecting an appropriate operating parameter based on the load condition and automatically sending a command to the computer system. An object of the present invention is to provide means for selecting operation parameters that have priority.

[Means for Solving the Problems] In order to achieve the above object, the operating device of the present invention is connected to an electronic computer system, and for a batch processing job, the processing time (turning time) of each job in the electronic computer system is reduced.・ Around time), the control means for displaying and transferring the result to the driving device of the present invention, and the driving device of the present invention for a job for measuring the response time such as TSS processing or online processing. And a control means for automatically generating a reference command sequence within the computer, sending the command sequence to the computer system, and measuring the response time. Further, a control means is provided for selecting an appropriate parameter from an operation parameter group stored in the storage means in advance based on the measurement data and transmitting the selected parameter to the command means.

Also, if the demand for TSS processing and online processing clearly decreases during the day, such as during the nighttime, the operating parameters mainly for batch processing are automatically selected at the specified time. , Control means for sending to the command means. This achieves proper load operation and labor-saving operation of the computer system.

[Operation] In the operating device of the electronic computer system of the present invention, when the load status of the electronic computer system is displayed on the display unit, the operating parameter corresponding to the load status is stored in the storage unit of the determination rule structure by the analysis processing control unit. And is provided to the computer system via the command processing means. As a result, the operating device of the present invention has input operator commands to the computer system in place of the system operator, that is, the operator, so that labor saving of the operator can be achieved and at the same time, the computer system is used for the operator. It operates as if an operator command has been input from the command means. Therefore, there is no need to modify the conventional operating system and no malfunction occurs.

An operation parameter file group 210 and a measurement data storage file (measurement data file) 220 are connected to the computer main body 200. Also, the computer main unit 2
The OS 260 is operating in 00, and when a job 265 is input, the job executes a batch job 250 or a TSS command process 255 for performing interactive processing from a terminal device. Since the TSS processing and the online processing can be handled in the same way in terms of the interactive processing and the quick response, the following description will proceed with the TSS processing.

In the operation device and operation monitoring method of the computer system according to the present invention, under the OS 260, a measurement program 240 for measuring the turn around time of each job of the batch processing and a turn for temporarily storing the measured data are provided. There are an around time table 235, a response time table 230 for TSS processing, and a measurement data transfer program 245. Here, the measurement data transfer program 245 includes: (1) a TSS command input processing program in the operating device 100

Now, the operation of the operating device of the computer system according to the present invention will be described with reference to FIGS. Referring to FIG. 1, when a batch processing job 265 is input to the OS 260, the measurement program 240 operates. The measurement program 240 registers the reception time of the job in the turnaround time table 235.

FIG. 2 shows the structure of the turnaround time table 235. In FIG. 2, reference numeral 1 denotes a turn around time (Turn Around time) for each job class.
Time: Hereinafter, abbreviated as TAT) is a table TATTAB that stores (1) the number of initiators (reference numeral 2) (2) the number of processes (reference numeral 3) (3) the average value of the TAT (for each job class) Reference numeral 4) (4) TAT variance and (5) detailed information (reference numeral 5) are stored. The detailed information 5 points to the processing status table 6 for each job (hereinafter abbreviated as JOBTAB _An ). JOBTAB _An 6 stores the name of the job, the reception time 7, the execution start time 8, and the end time 9, and based on these information, the average value 4 of the TAT in TATTAB1 and the TAT
The calculation of the variance of is immediately possible. For the job class and the initiator in the operating system, refer to the following publications.

"VOS3 Explanation" Hitachi Manual; 8091-3-0
01 "VOS3 / ES JSS4 Explanation" Manual for Hitachi, Ltd .; 8091
Therefore, the measurement program 240 stores the reception time in the reception time field in JOBTAB _An 6 that responds to the job class when the job 265 is received. Next, the OS
When the 260 executes the job as a hatch job 250, the control is transferred from the OS 260 to the measurement program 240, and the JO
The execution start time is stored in the start time field 8 in the BTAB _An 6.

After that, when the processing of the job 265 is completed in the batch job 250, the control is transferred again to the measurement program 240,
The end time is stored in the end time field 9. At this time, the number of cases processed in TATTAB1 is counted up and TATAB1 is counted up.
Calculate the average value of 4 and the variance of the TAT.

As described above, the turnaround time of the batch processing is always stored in the turnaround time table 235.

Next, a method of measuring a response time in the TSS processing will be described. The feature is that the response time of the TSS processing is not measured in the computer main body 200 but is measured in the driving device side of the present invention. This is because the response time of the TSS processing consists of the data transfer time from the computer main unit to the terminal device in addition to the processing time in the computer main unit, which matches the user's sense of use at the terminal device. The response time is obtained.

The TSS command input processing / response time measurement program 165 in the driving device 100 is a benchmark / command sequence file 1
Take out the TSS command sequence sequentially from 35 and go to O through line 1.
Transfer to TSS command processing 255 on S260, time at this time
remember the t _1. When the processing of the TSS command ends in the TSS command processing 255, the result is returned via the line l2, and at the same time, it is displayed on the TSS screen 185 in the display device 110 by the display processing 145. At this time, TSS command input process and response time measurement program 165, after remember end time t ₂ of the TSS command, it calculates the response time. This can be done by calculating t ₂ −t ₁ . Next, another TSS command sequence is transmitted via the line 1 so that the corresponding TS
The S command is executed, and the response time of the TSS command is measured on the driving device 100 side. As described above, when the measurement of the TSS response time by the benchmark command sequence including a series of TSS command sequences is completed, the response time data of each TSS command is transferred to the measurement data transfer program 245 operating under the OS 260 via the line l3. And stored in the response time table 230. At this time, the measurement data of the TSS response time is also stored in the measurement data table 150 in the driving device 100. For the format and details of the TSS command, refer to the following publications.

"VOS3 / ES TSS Operation" Hitachi Manual, 8091-9
−034 “VOS3 / ES TSS Command” Hitachi Manual, 8091
-3-037 The TSS command input processing / response time measurement program 165 always measures. Since the contents of the benchmark command string file can be modified by the definition registration means 140, the benchmark command can be changed at any time.

FIG. 3 shows details of the response time table 230 shown in FIG. The format of the response time table 230 and the format of the measurement data table 150 are the same. The measurement data table 150 has, in addition to the measurement data of the TSS response time, measurement data of the turnaround time of the batch processing, which has the same format as TATTAB1 in FIG.

Referring again to FIG. 3, the response time table 230
Numeral 11 denotes the number N of entries in the table, numeral 12 denotes the total response time of the benchmark command group, numeral 13 denotes the TSS command name, and numeral 14 denotes the response time of the TSS command indicated by numeral 13. Note that there are pairs of the command name 13 and the command response time 14 as many as the number of entries 11 in the table.

The measurement data transfer program 245 stores the contents of the response time table 230 and the turnaround time table 235 in the measurement data file 220 together with time stamp data (output time data) at regular intervals.
As described above, by storing the time-series information in the measurement data file 220, the analysis can be performed at a later date. It should be noted that the fixed time value may be set to about 15 minutes as a guide. Normally, the operation may be performed when the TSS benchmark command group completes one cycle. The measurement data transfer program 245 stores a response time table 230 and a turn around time table 235 in the measurement data file 220.
Output the contents of TATTAB1 at the same time
4 to the driving device 100. As a result, the measurement data of the turn around time of the batch processing is also stored in the measurement data table 150, and further, the batch processing screen 186 on the display device 110 is displayed by the display processing program 145 on the batch processing screen 186. The turnaround time for each job class is displayed.

This allows the computer system administrator and the system operator to visually check the load status displayed on the display screen of the display device 110, and to constantly grasp the behavior of the computer system. Becomes

Next, the operation of the automatic selection of the appropriate operating parameters and the operation of the automatic transmission control method based on the load condition, which are the main functions of the present invention, will be described. The measured data table 150 in the driving device 100 includes TATTAB1 in FIG. 2 and TS in FIG.
The S response time table 230 is stored.

The analysis processing unit in the driving device 100 receives the load condition data of the measurement data table 150 as input, and
Based on the determination conditions described in the above, an appropriate operation parameter is selected.

FIG. 4 shows the structure of the decision rule structure 155, which is a set of control table groups. That is, the judgment rule structure 155 includes the judgment level table 21, the driving guideline table 2
2. Consists of a decision criterion table 23, a time zone schedule table 24, and an operation command table 25.

The judgment level table 21 stores threshold _{values 1} to _n and detailed information, and a target TSS response time value and a turnaround time value of batch processing are set in the threshold value. The detailed information indicates which criterion of the decision criterion table 23 is to be used, and specifically points to the entry of the decision criterion table 23.

The operation guide table 22 stores detailed information corresponding to the operation guide of the computer system. The operating guidelines include guidelines such as (1) securing TSS proper response time for demonstration of TSS processing when important customers are scheduled to visit, etc. (2) securing batch processing jobs of a specific job class. It is shown.

The determination criterion table 23 is used to determine whether to increase or decrease the number of initiators of a specific class of a batch processing job, to determine whether to increase or decrease the number of allowable sessions in TSS processing, and to determine the performance management parameter (In
Determination criteria, such as determination of a change in stallation Performance Specification (IPS), are stored, and point from the detailed information area 26 to the corresponding command identification name in the operation command table 25. For performance management parameters, refer to the following publications.

"VOSS3 / ES Center Operation" Hitachi, 8093-3-011 The operation command table 25 stores operator operation commands corresponding to the criteria selected from the determination criteria table 23 described above. For details of the operation commands, refer to the following publications.

"VOS3 / ES System Operation" Hitachi Manual; 80
91-9-012 For example, when changing the number of initiators for a batch processing job, the $ F command stores the data stream of the system operation command of \ FG, processor name, G, group name, INIT, nnn. Have been. Here, the symbol “△” indicates a space, and nnn indicates the number of initiators. Similarly, regarding the change of the performance management parameter, the data stream of the system operation command of SET IPS = mm is stored. Here, mm represents an identifier of a file of a performance management parameter in the operation parameter file group 210 shown in FIG. Therefore, it is possible to prepare a plurality of performance management parameter files, and the operation command for setting the value of the maximum allowable number of sessions of the TSS processing according to the load on the system and the operation command Since it is stored in the table 25, if the increase or decrease in the number of TSS sessions is determined by the determination criterion 23, the corresponding operation command is selected.

In general, the number of TSS sessions is distinctly different between daytime and nighttime periods, and the number of TSS sessions during nighttime periods is significantly reduced compared to daytime. If the load on the system is clearly different,
The start time 27 and the end time 28 are used in the time zone schedule table 24. That is, if the operation guideline table 22 indicates that the time zone schedule is to be performed and the number of initiators of the batch processing job is increased, or the performance management parameter indicates that the batch processing is to be prioritized, the start criterion 27 indicates that the start time is 27 A corresponding criterion is selected, a corresponding operation command is extracted from the operation command table 25, and transmitted to the OS 260 via a line 15 in FIG. Similarly, at the end time 28, an operation command for returning to the original state is sent to the OS 260 via the line l5. in this way,
The process of transmitting the data stream of the operation command to the OS 260 is performed by the command process 170 of FIG.

Referring again to FIG. 1, the analysis processing 160 receives the performance data of the measurement data table 150 as an input, and determines the threshold value and the operation guideline table 22 of the judgment level table 21 (FIG. 4) in the judgment rule structure 155. Determine operating conditions more. Next, the determination criterion table 23 is searched to determine whether to decrease or increase the number of initiators of the batch processing job and to change the maximum allowable number of sessions of the TSS processing.

In the determination level 21 in the overload state,
A criterion that guarantees the response time of the TSS process and the online process as the highest priority is set, and the determination criterion is to first try to reduce the number of initiators of the batch processing job.

When the change of the operation state is determined, the analysis processing 160 extracts the data stream of the corresponding operation command from the operation command table 25 and passes it to the command processing 170. Note that if the analysis process 160 specifies a time zone schedule in the driving guideline table 22 in the rule structure 155, as described above, the information in the time zone schedule table 24 is also taken into account as a determination criterion. Is done.

Command processing 170 starts from the analysis processing
When the stream is passed, the data stream is sent to the OS 260. In addition, the operation command
Even when only the entry number in the table 25 is passed, the command processing 170 searches the operation command table 25, extracts the data stream corresponding to the entry number, and qualifies the data stream with the detailed information in the entry. Later, make a complete form of operation command, OS26 via line l5
Send to 0.

The OS 260 treats the data stream of the operation command as the same as that input from the conventional command means, processes the operation command, and returns the command and the processing result via the line l6. The data stream is displayed on the console screen 187 via the display processing 145 via the line l6.

In the embodiment of the present invention, the lines l5 and l6, the lines 1 and l2, and the lines l3 and l4 are shown separately from each other. One signal line is sufficient. Further, the signal lines of the three function units may be used, or the three functions may be controlled by one signal line 17. In any case, in such a case,
What is necessary is just to provide the data transmission / reception processing part in the driving device 100, and the realization method can be easily analogized.

The distribution processing 180 is performed by the command means 120 added to the driving device 100.
Therefore, even when the operator of the computer system urgently inputs a command manually, a process for transmitting the input data stream to the OS 260 is performed. This allows
Conventional operability is not impaired.

The contents of the determination rule and the benchmark command sequence can be changed by the definition registration process 140. To register or modify the benchmark command sequence, the contents of the benchmark command sequence file 135 may be modified.

When registering / correcting the contents of the judgment rule structure 155, the contents of the judgment rule file 130 are corrected by the definition registration process 140. When this correction is completed, the registration process 175 reads the judgment rule file 130 and stores the information in each table group of the judgment rule structure 155 shown in FIG.

[Effects of the Invention] According to the present invention, the operating device constantly monitors the load state of the computer system, automatically selects an appropriate operating parameter according to the load condition, and issues a command to the computer system. Since it is possible, the automatic operation of the computer system becomes possible, and there is an effect that the proper load operation can always be realized.

Furthermore, since priority is given to jobs requiring responsiveness such as TSS processing and online processing, the response time is assured, so that there is an effect that a terminal device user can use a computer system with high responsiveness. .

In addition, the operation parameters for performance management are automatically changed during the daytime and nighttime hours, so that operation prioritizing TSS processing during the daytime and operation prioritizing batch processing at nighttime can be performed automatically. Has an effect.

Furthermore, in the measurement of the load status of the electronic computer system, the response time of each command of the TSS processing is measured on the driving device side for jobs where response time is important such as TSS processing. Thus, there is an effect that a response time that matches the usage sensation of the terminal user can be obtained.

Further, since the load state measurement data can be stored as time-series data in the auxiliary storage device, there is an effect that detailed analysis can be performed at a later date.
