[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic operation device for a computer system, and in particular, to an automatic operation device for an electronic computer system, and in particular, an automatic operation device that automatically selects optimal operation parameters according to load conditions and automatically issues commands. The present invention relates to a control method and an operating device that always realize proper operation by emitting a signal.

[Prior Art] Conventionally, regarding automatic operation control methods for information processing systems such as electronic computer systems, there is a control method in which two sets of operation schedule files are provided and the operation schedule is changed without stopping the system. -182822
Disclosed in the issue.

Regarding the proper operation of information processing systems, Japanese Patent Laid-Open No. 17486 (1982) proposed a method for controlling the number of user connections ("sessions") in interactive time-sharing information processing systems.
It is disclosed in No. 0.

[Problems to be Solved by the Invention] Regarding the prior art, the technology described in Japanese Patent Application Laid-Open No. 182822/1982 prepares two schedule files consisting of a schedule table for job execution and a job procedure, and - By inputting a switching command that updates the contents of the other schedule file while the file is in use, the job execution schedule is changed based on the contents of the updated schedule file. This is intended to prevent automatic operation from being interrupted due to changes in job execution schedules. The technology disclosed here seems to be intended to realize automatic driving by specifying the execution start time of each job and executing the job at the specified time.

Here, the disclosed technique is a schedule of jobs to start execution, and does not take into account the load status of the entire system. Furthermore, from the viewpoint of automatic operation of computer systems (also referred to as information processing systems), it is important to save the operator's labor and to operate the computer system under an appropriate load.

From this point of view, with the technique disclosed in Japanese Patent Laid-Open No. 182822/1982, the operator must input a switching command, making it difficult to achieve labor savings.

Also, if you control the start of job execution based only on time dependence,
It is also difficult to realize loading operations when irregular-sized jobs are mixed. Additionally, batch processing jobs and time sharing
Time Sharing System
The method for scheduling driving when conversation processing and online processing (TSS) are mixed is not disclosed.

On the other hand, the technology disclosed in JP-A No. 62-174860 sets a permissible number of sessions, prevents the load on the electronic processing system from exceeding the limit, and even if the permissible number of sessions is exceeded, it is processed with priority. However, there is no mention of a means for determining the number of allowed sessions.

By the way, the usage patterns of electronic computer systems are becoming more and more diverse.
As complexity increases, automatic operation that takes advantage of the experiential knowledge of operating operators, appropriate load operation when irregular jobs are mixed, batch processing, TSS processing, and online processing mixed, and labor-saving operation are becoming more important. , and a way to do this automatically remains an issue.

Therefore, one object of the present invention is to provide an operating device equipped with a mechanism that constantly monitors the load status of the system and automatically sends out appropriate operating parameters based on the load status, in order to realize automatic operation of a computer system. Our goal is to provide the following.

Another object of the present invention is to automatically change operating parameters when the computer system is operating, and when the load on the system is obviously different depending on the time of the day, such as during the day, at night, or on holidays. The object of the present invention is to provide an operating device equipped with a mechanism for

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

Another object of the present invention is to provide a control means that can immediately measure the response time of each jib and command such as batch processing and TSS processing, and store the measured data in chronological order.

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 the load situation when selecting appropriate operating parameters based on the load situation. It is an object of the present invention to provide a driving support control means that uses a load condition that matches a person's sense of use as a determination criterion.

Another object of the present invention is to guarantee the response time of TSS processing and online processing when selecting appropriate operating parameters based on load conditions and automatically sending commands to a computer system. The object of the present invention is to provide a means for selecting priority operating parameters.

[Means for Solving the Problems] In order to achieve the above object, the operating device of the present invention is connected to a computer system, and for batch processing jobs, the processing time (turn) of each job is calculated within the computer system.・
around time) and displaying and transmitting the results to the operating device of the present invention, and one unit within the operating device of the present invention for jobs that measure response times such as TSS processing and online processing. The control means automatically generates a reference command string, sends it to the computer system, and then measures its response time. Furthermore, based on these measurement data, the control means selects appropriate parameters from a group of operating parameters stored in advance in the storage means and sends them to the command means.

In addition, during the operation on day -, if the demand for TSS processing or online processing clearly decreases, such as during night hours, the batch processing-based operating parameters will be automatically selected at the specified time. , and control means for sending the command to the command means. As a result, proper load operation and labor-saving operation of the computer system can be achieved.

[Operation] In the computer system operating device of the present invention, when displaying the load status of the computer system on the display unit, the analysis processing control unit stores the operating parameters corresponding to the load status in the storage unit of the judgment rule structure. The command is extracted from the command processing means and given to the electronic computer system through the command processing means. As a result, the operating device of the present invention is installed in the electronic computer system in place of the system operator, that is, the operator.
Since the command has been input, the operator's labor can be saved, and at the same time, the electronic computer system operates as if the operator command had been input from the operator command means. Therefore, there is no need to modify the conventional operating system and there is no possibility of malfunction.

Further, a rule structure expressing driving operations according to load conditions and a reference TSS command sequence (benchmark command sequence) for measuring response time of TSS processing etc. are registered by the registration means.

Therefore, it is easy to change the operating policy of the computer system at any time.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a diagram succinctly showing the configuration of an operating device for an electronic computer system according to the present invention. Figure 2 shows the turnaround time table shown in Figure 1.

, analysis%i part 160. A command to send the command string to the computer system main body 200 when the TSS command automatic sending processing section 165 and analysis processing section 160 extract a proper system operation command and command string from the judgment rule structure 155. Message data between the processing unit 170, the registration processing unit 175 for the judgment rule structure 155, and the computer main body 200 and the operating device 100,
It consists of a command data distribution processing section 1801 and a standard registration processing section 140 for the judgment rule file 130 and benchmark command string file 135.

The computer main body 200 includes an operating parameter file group 210 and a measurement data storage file (measurement data
File) 220 is connected 6 Also, 08260 is running inside the computer main body 200, and job 2
65 is submitted, the job becomes batch job 250.
Also, TSS command processing 255 for performing interactive processing from the terminal device is executed. Note that since TSS processing and online processing can be treated in the same way in terms of interactive processing performance and immediate response, the following discussion will be based on TSS processing.6 Regarding the computer system operating device and operation monitoring method of the present invention, ,
Under 08260, each job's turn in batch processing
There are a measurement program 240 that measures around time, a turnaround time table 235 that temporarily stores measured data, a response time table 230 for TSS processing, and a measurement data transfer program 245. Here, the measurement data transfer program 245 is.

(1) Receiving benchmark command response time data measured by the TSS command input processing program 165 in the operating device 100 and storing it in the response time table 230.

(2) Data of the turnaround time table 235 and data of the response time table 230 are transferred to the driving device 100 and the measurement data file 220.

Now, the operation of the operating device for the computer system of the present invention will be explained using FIGS. 1 to 4. Referring to FIG. 1, when a batch processing job 265 is input to 5260, the measurement program 240 starts operating. Measurement program 2
40 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 Figure 2, reference numeral 1 indicates the turnaround time (Turn A) for each job class.
The table TATTAB stores the round time (hereinafter abbreviated as TAT), and for each job class, (1) the number of initiators (code 2), (2) the number of processes (code 3), and (3) the average value of TAT. (Symbol 4) (4) TAT variance and (5) detailed information (Symbol 5) are stored. The detailed information 5 points to a processing status table 6 for each job (hereinafter abbreviated as JOBTABA-0). JOBTAB A-n6 stores the name of the job, reception time 7, execution start time 8, and end time 9, and based on this information, TATTAB
The mean value of TAT in l and the variance of TAT can be calculated immediately.

For information on job classes and initiators in operating systems, please refer to the publications listed below.

3/ES JSS4 Explanation” Hitachi, Ltd. manual;
8091-3-019 Therefore, the measurement program 240 sometimes accepts the job 265 using JOBTABA that responds to the job class.
For reception in -r16, the reception time is stored in the time field. Next, when the 08260 executes the job as the hatch job 250, control is transferred from the 08260 to the optical measurement program 240, JOBTABA-,6
The execution start time is stored in the start time field 8 in .

Thereafter, when the processing of the job 265 in the batch job 250 is completed, control is transferred to the measurement program 240 again, and the end time is stored in the end time field 9. At this time, the number of processed cases 3 in TATTAB l is counted up, and the average value 4 of TAT and the variance of TAT are calculated.

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

Next, a method for measuring response time in TSS processing will be explained. The response time of TSS processing is 20
The feature is that the measurement is not performed within 0, but is performed on the operating device side of the present invention.

This is because the response time of TSS processing consists of the processing time within the computer itself, as well as the data transfer time from the computer body to the terminal device, and it is consistent with the user's sense of use with the terminal device. The goal is to get better response time.

The TSS command input processing/response time key program 165 in the operating device 100 sequentially extracts TSS command strings from the benchmark command string file 135,
TSS command processing 255 on 08260 via line Q1
The time t□ at this time is stored. When the processing of the TSS command is completed in the TSS command processing 255, the result is returned via the line Q2, and at the same time, the display processing 14
5 on the TSS screen 185 in the display device 110. At this time, the TSS command input processing/response time measurement program 165 determines the end time t of the TSS command.
After memorizing step 2, calculate the response time. This is 12-14
All you have to do is calculate. Next, by sending another TSS command sequence via line Q1, the corresponding TSS command is executed in TSS command processing 255, 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 using the benchmark command string consisting of a series of TSS command strings is completed, the response time data of each TSS command is transferred to the measurement data transfer program 245 operating under ○5260 via the line Q3. The data is transferred and stored in the response time table 230. Also, at this time, the measurement data of the TSS response time is
It is also stored in the measurement data table 150 within the driving device 100. For the format and details of the TSS command, please refer to the following publications.

Can be changed.

FIG. 3 shows details of the response time table 230 shown in FIG. 1. The format of this response time table 230 and the format of the measurement data table 150 are the same. In addition,
In addition to the measurement data of the TSS response time, the measurement data table 150 also includes measurement data of the turnaround time of batch processing.
It has the same format as AB1.

Referring again to FIG. 3, response time table 230
The code 11 inside is the number N of entries in the table.

Reference numeral 12 is the total response time of the benchmark command group, reference numeral 13 is the TSS command name, and reference numeral 14 is the response time of the TSS command indicated by reference numeral 13. Note that there are as many pairs of command names 13 and command response times 14 as indicated by 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. In this way, by storing it as time series information in the measurement data file 220, it is also possible to analyze it at a later date. Note that the fixed time value may be approximately 15 minutes, and normally, it is sufficient to operate when one cycle of the TSS benchmark command group is completed. When the measurement data transfer program 245 outputs the contents of the response time table 230 and turnaround time table 235 to the measurement data file 220, it simultaneously sends the contents of TATTABl to the driving device 100 via the line Q4. do. As a result, the measurement data of the batch processing turnaround time is also stored in the measurement data table 150, and the batch processing data is also displayed on the batch processing screen 186 on the display device 110 by the 1 display processing program 145. The turnaround time for each job class is displayed.

This makes it possible for the administrator and system operator of the computer system to visually check the load status displayed on the display screen of the display device 110, and to understand the behavior of the computer system at all times. becomes.

Next, the automatic selection of appropriate operating parameters based on the load situation and the operation of the automatic delivery control system, which are the main functions of the present invention, will be explained. The measurement data table 150 in the operating device 100 stores TATTABl in FIG. 2 and the TSS response time table 230 in FIG. 3.

The analysis processing unit in the operating device 100 receives the load status data from the measurement data table 150 and selects appropriate operating parameters based on the judgment conditions written in the judgment rule structure 155.

FIG. 4 shows the configuration of the judgment rule structure 155, which is a set of control tables. That is, the judgment rule structure 155 is made up of a 1 judgment level table 21, an operation guide table 22, a decision criteria table 23, a time period schedule table 24, and an operation command table 25.

The judgment level table 21 has threshold values, .about.threshold values. and detailed information are stored, and the target TSS response time value and batch processing turnaround time value are set as the threshold values. The detailed information indicates which criterion in the decision criteria table 23 is to be used, and specifically points to the corresponding entry in the decision criteria table 23.

The driving guidelines table 22 stores detailed information corresponding to the driving guidelines of the electronic computer system.

The operating guidelines include: (1) TSS when important customers are scheduled to visit.
It provides guidelines such as securing an appropriate TSS response time for processing demonstrations (2) securing batch processing jigobs for specific job classes.

The decision criteria table 23 determines whether to increase or decrease the number of initiators for a specific class of batch processing jobs, determines whether to increase or decrease the number of permissible sessions in TSS processing, and determines performance management parameters (
Installation Performance
The detailed information area 26 points to the corresponding command identification name in the operation command table 25.

Regarding performance management parameters, please refer to the following publications.

"rVO8s3/ES Center Management" Hitachi Urasakusho: The operation command table 25 is based on the decision criteria table 2 shown earlier.
Operator operation commands corresponding to the criteria selected from 3 are stored.

For details of the operation commands, please refer to the following publications.

rVO83/ES System Operation" Hitachi, Ltd. Manual; 8091-9-01 For example, to change the number of initiators for a batch processing job, use the \F command, \FG, processor name, G, group name + I' A data stream of system operation commands for NIT and nnn is stored. Here, the Δ mark means a blank.

nnn represents the number of initiators. Similarly, for changing performance management parameters, SET IPS=m
A data stream of m system operation commands is stored. Here, mm represents the identifier of the performance management parameter file in the operating parameter file group 210 shown in FIG. Therefore, it is possible to prepare multiple files for performance management parameters, and depending on the load on the system, the operation command for setting the maximum allowable number of sessions for TSS processing can also be changed. Since it is stored in the table 25, if an increase or decrease in the number of TSS sessions is determined based on the decision criterion 23, the corresponding operation command is selected.

Generally, the number of TSS sessions is clearly different between daytime hours and nighttime hours, and the number of TSS sessions during nighttime hours is significantly lower than during the daytime. In this way, when the load on the system is clearly different,
Start time 27 is shown in this time period schedule table 24.
and end time 28 are used. In other words, if the operation guideline table 22 indicates that a time period schedule is to be performed and the number of initiators for a batch processing job is increased, or that the performance management parameter is set to give priority to batch processing, then at start time 27, the decision criteria table Select the applicable criteria, extract the corresponding operation command from the operation command table 25, and send it to 0326 via line Q5 in FIG.
Send to 0. Similarly, at end time 28, an operation command to return to the original state is sent via line 25 to ○526.
Send to 0. In this way, the process of sending the data stream of the operation command to 08260 is performed by the command processing 170 in FIG.

Referring again to FIG. 1, the analysis process 160 takes as input the performance data of the so-called data table 150 and analyzes the judgment level table 21 (FIG. 4) in the judgment rule structure 155.
The operating conditions are determined based on the threshold value and the operating guideline table 22.

Next, the decision criteria table 23 is searched to determine whether to decrease or increase the number of initiators for the batch processing job, and whether to change the maximum allowable number of TSS processing sessions.

In addition, at determination level 21 in the overload state,
Standards are set to guarantee the response time of TSS processing and online processing as the top priority, and the first step in the decision criteria is to try to reduce the number of initiators for batch processing jobs.

When a change in the operating state is determined, the analysis process 160 extracts the data stream of the corresponding operation command from the operation command table 25 and passes it to the command process 170. Note that if the time period schedule is specified in the operating guideline table 22 in the rule structure 155, the analysis processing 160 also takes into account the information in the time period schedule table 24 in the decision criteria, as described above. be done.

The command processing 170 includes analysis processing and operation command data.
When passed the stream, it sends the data stream to 08260. Note that even when only the entry number in the operation command table 25 is passed from the analysis processing 160, the command processing 170 searches the operation command table 25 and retrieves the data corresponding to the entry number.
After extracting the stream and qualifying it with the details in its entry, we create a fully-formed operation command and write it on line Q5.
Send to 05260 via.

○5260, the data stream of the operation command is treated as if it were input from a conventional command means, and the operation command is processed.

The command and processing results are returned via line Q6. The data stream via line Q6 is sent to display processing 145.
It is then displayed on the console screen 187.

In the embodiment of the present invention, lines Q5 and Q6, lines Q1 and Q2, and lines Q3 and Q4 are shown separately from each other, but this is for ease of explanation, and each One signal line is sufficient. Further, signal lines may be provided for each of the three functions, or the three functions may be unified by one signal line ρ7. In any case, in such a case, a data transmission/reception processing section may be provided in the operating device 100, and the method for realizing this can be easily deduced by analogy.

The distribution processing 180 is for sending the input data stream to the ○5260 even when the operator of the electronic computer system manually inputs an urgent command from the command means 120 added to the operating device 100. Process. This does not impair conventional operability.

The content of the determination rule and the benchmark command string can be changed by the definition registration process 140. The benchmark command string can be registered or modified by modifying the contents of the benchmark command string file 135.

When registering or modifying the contents of the judgment rule structure 155, the judgment rule file 130 is
Modify the contents of. Once this modification is completed, registration process 1
75 reads the judgment rule file 130 and stores 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 can constantly monitor the load condition of the computer system, automatically select appropriate operating parameters according to the load condition, and issue commands to the computer system. Therefore, automatic operation of the electronic computer system becomes possible, and there is an effect that proper load operation can be realized at all times.

Furthermore, since the response time is guaranteed by giving priority to jobs that require responsiveness such as TSS processing and online processing, the user of the terminal device has the effect of being able to use a computer system with high responsiveness. .

In addition, performance management operating parameters are automatically changed during daytime and nighttime hours, so operations that prioritize TSS processing during the day and batch processing at night can be automatically performed. It has the effect of

Furthermore, when measuring the load status of a computer system, for jobs where response time is important, such as TSS processing, the response time of each command for TSS processing is measured on the operating device side. This has the effect of providing a response time that matches the terminal user's sense of use.

Furthermore, since the measurement data of the load status can be stored as time-series data in the auxiliary storage device, detailed analysis can be performed at a later date.
