  Until now, large computers such as mainframes have been used in large-scale job execution systems for a long time. However, in recent years, replacement with an open system such as a UNIX (registered trademark) server has been actively performed in order to age the mainframe and reduce maintenance costs. At this time, centralized processing by a single mainframe type machine with one ordinary UNIX (registered trademark) server is impossible, and a load distribution system to a large number of machines connected to the network is constructed.

  When constructing such a system, a control server used for load distribution executes control of transfer / execution / result acquisition of a large number of jobs, so that signals and data associated with these processes are collected on the control server. For this reason, it is difficult for one control server to perform control processing for load distribution. Even if processing can be performed, the cost of monitoring the execution status, execution results, and execution history of a large number of jobs is enormous.

  A disclosure example regarding load distribution related to a job execution system is shown below.

In the job network control system of Patent Document 2, a system that handles a job that does not wait for a preceding job is selected by a job network control apparatus that centrally manages a plurality of systems that execute jobs, and starts a job for each system. Each system notifies the job network control apparatus of the job processing result for job activation. However, each system must hold a job network and all jobs included in the job network. Further, when the job network control apparatus creates a new job network, it is necessary to transmit the job network to each system.

Japanese Patent Application Laid-Open No. 08-095916 discloses a business job monitoring method for executing a business job on a computer having a business job schedule and execution means and monitoring the execution status (see Patent Document 3). The business job monitoring method disclosed in Patent Document 3 summarizes business jobs for each business group according to instructions from the supervisor, sets an allowable delay time for each business group, and delays the end of execution of the business group beyond this allowable time. Or issue a warning when it ends abnormally.

(Operation)
The operation in the embodiment of the job execution monitoring system according to the present invention will be described with reference to FIGS.

  With reference to FIG. 4, the operation of the job network execution control process of the job control apparatus 1 will be described in detail.

  When executing the job network 51, the schedule control unit 14 of the job control apparatus 1 refers to the time output from the timer 17, and the job network corresponding to the start condition 511 that matches this time from the job network definition D / B 100. 51 is extracted (step S102). Next, the job network control unit 15 is notified that the job network 51 has been prepared for execution, and the extracted job network 51 is transferred to the job network control unit 15.

  The job network control unit 15 disassembles the transferred job network 51 for each job 52 (step S104). Referring to FIG. 6, a conceptual diagram of job network 51 and job 52 is shown. The job network 51 shown in FIG. 6A includes a job A 52-1, a job B 52-2, a job C 52-3, and a job D 52-4. The job network control unit 15 includes the job network 51 shown in FIG. Disassembled into job 52 as shown in b). FIG. 6C is an example of a job parameter 59 that is a job execution condition that associates each element of the job network 51 shown in FIG. 3 for each job. Job parameters 59 correspond to job A52-1, job B52-2, job C52-3, and job D52-4, which are jobs 513 constituting the job network 51, respectively, and jobs A to D as job IDs 512, execution terminals The job execution apparatus, which is the apparatus 514, a spare job execution apparatus, an execution order, and a linkage relationship 515 are provided. In the case of the present embodiment, the job execution apparatus 2-1 initially executes job A, and then causes job execution apparatus 2-2 and job execution apparatus 2-3 to execute job B and job C in parallel. When both the jobs 52 are completed, the job execution apparatus 2-5 is caused to execute the job D. If an error occurs when job A is executed and cannot be terminated, the job execution device 2-2 is caused to execute job A as a spare job execution device.

  After disassembling the job, the job network control unit 15 selects the job 52 (here, job A 52-1) based on the execution order, stores it in the job D / B 101, and transfers it to the job control unit 16 (step S1). S106). At this time, job A 52-1 is stored as job ID 521 in association with job A. Until the execution of the job A 52-1 is completed and acquisition of the execution result is completed, the transfer of the job B 52-2, the job C 52-3, and the job D 52-4 to the job execution unit 21 is awaited.

  The job control unit 16 transfers the job A 52-1 received from the job network control unit 15 to a predetermined job execution device (in this case, the job execution device 2-1) according to the job parameter 59. The job A 52-1 is temporarily stored in the job D / B 22 of the transfer destination job execution apparatus 2-1 and executed by the job execution unit 21. The job execution unit 21 starts execution of the job A 52-1, and transmits an event 53 indicating that the job A 52-1 has a status of “executing” to the job control unit 16.

  The job control unit 16 updates the status of the event 522 corresponding to the job A 52-1 of the job D / B 101 to “in execution” based on the event 53 received from the job execution apparatus 2, and notifies the job network control unit 15 of the event. 53 is transferred. The job network control unit 15 transfers the event 53 to the differential event management unit 12 via the event transmission unit 11. The differential event management unit 12 extracts the transmitted event 553 that matches the job network ID of the transferred event 53 from the differential event D / B 103, compares it with the event 53, and determines an event that has not been transmitted to the job monitoring terminal 3. Created as a differential event 56. The difference event management unit 12 stores the created difference event 56 in the difference event D / B 103, and updates the difference event 552 (step S110).

  The job network control unit 15 refers to the event type of the event 53 received from the job execution device 2 to determine whether the event is an abnormal event 54 indicating an execution error (step S116). Then, it is determined whether or not it is the end event 55 (step S112). When the event 53 is not an end event 55 but an event indicating the status of the job execution status, the event 53 from the job execution apparatus 2 is awaited. If the received event 53 is the end event 55, the job network control unit 15 transfers the end event 55 to the integrated monitoring terminal 4 via the event transmission unit (step 113). Also, a job execution result (end code, standard output, standard error output) corresponding to the job ID of the end job 55 is extracted from the job D / B 101, the information is written in the job network D / B 102, and the job history 58 is stored. Create and update (step S114).

  If the end event 55 received by the job network control unit 15 is not the end job of the final job of the job network 51, the job parameter 59 is referred to, and the next is determined based on the execution order or linkage relationship that is the job start condition. The job 52 to be executed is selected (step S106), and the job 52 is transferred to the predetermined job execution apparatus 2 and executed (step S108). When the received end event 55 is an event indicating the end of the final job of the job network 51, the job execution apparatus 1 ends the execution process of the batch network 51.

  In step S110, if the event 53 received by the job network control unit 15 is an abnormal event 54, that is, indicates an abnormal end of the execution result of the job 52, or a predetermined time set in the job network 51. When exceeding (not shown), the job network control unit 15 transmits the abnormal event 54 to the integrated monitoring terminal 4 via the event transmission unit 11 (step 118). The abnormal event 54 includes a related job network ID 441 and job ID 442, an event 443 including the content of the abnormal status, an event type 444 indicating alarm information, and an event occurrence time 445.

  The job network control unit 15 refers to the job parameter 59, and when the spare job execution device 2 for executing the job is designated, the job network control unit 15 changes the job execution device 2 and changes the job 52 to the job execution device 2. Transfer and execute (step S122). When the spare job execution device 2 is not designated or when the abnormal event 54 is received from the spare job execution device 2, the process proceeds to step S114 as an abnormal end event.

  As described above, the job execution monitoring system according to the present invention is divided into the job network control unit 15 and the job execution control unit 16, and processes the job network in cooperation with the two controls. Enables centralized control of network distributed job execution systems.

  Further, the job control apparatus 1 is notified of the execution status of the job 52 in the form of an event 53, and the job control apparatus 1 can immediately grasp the execution status of the job 52 on the job execution apparatus 2. At this time, the job execution status or the status of the execution result is notified to the job control apparatus 1 in the format of event 53, and the job execution result 57 is separately acquired, and even if a large number of execution results of the job 52 are output, the job The update of the status of the control device 1 is not delayed.

  With reference to FIGS. 2 and 5, the operation of job execution processing in the job execution monitoring system according to the present invention will be described.

  The job control apparatus 1 extracts the job network 51 that matches the activation condition 511 from the job network definition D / B 100 (step S2). Next, the job network 51 is disassembled for each job 52 (step S4), and the job 513 is selected based on the execution order 515 included in the job network 51 (step S6). The selected job 513 (for example, job A 52-1) is transferred to a predetermined execution terminal device 514 (for example, job execution device 2-1) and an execution command is issued (step S8).

  When job execution apparatus 2-1 receives job A 52-1 and receives an execution instruction, job execution unit 21 executes job A 52-2 (step S 10). When the job execution apparatus 2-1 starts the job A 52-2, the job execution apparatus 2-1 transmits an event 53 indicating that the job A 52-2 is being executed to the job control apparatus 1 (step S12).

  The job control device 1 stores the event 53 received from the job execution device 2-1, and creates and stores the event history 58 (step S14). When the job execution apparatus 2-1 ends the job A 52-1, the job execution apparatus 2-1 transmits an end event 55 and a job execution result 57 to the job control apparatus 1 (step S16). The job execution apparatus 1 stores the received end event 55 and updates the event history 58 (step S18). The received job execution result 57 is stored (step S20).

  Upon receiving the end event 55, the job control apparatus 1 transfers the next job 52, for example, job B 52-2, to the job execution apparatus 2-2 based on the job start conditions (order and linkage relationship) of the job network 51. An execution instruction is issued (step S24). At this time, when the job B 52-2 and the job C 52-3 are processed in parallel, the job C 52-3 is transferred to the job execution apparatus 2-3 and an execution command is issued simultaneously with the transfer of the job B 52-2 (step S28). The job execution device 2-2 and the job execution device 2-3 execute the received job 52 (steps S26 and S30). As described above, the job execution monitoring system executes the transfer and execution of the job 52, the transfer of the event 53, and the job switching. Upon receiving the end event 55 and the execution result of the final job 52 of the job network 51 (step S32), the job control apparatus 1 stores the end event 55, updates the event history 58, stores the execution result, and saves the job. The execution process of the network 51 is terminated.

  As described above, in the job execution monitoring system according to the present invention, the job control apparatus 1 disassembles a job network including a large-scale job for each job, and transfers and executes only the jobs in charge to the job execution apparatuses 2-1 to n. Therefore, the communication load at the time of job network execution control can be suppressed. Further, each job execution device 2 only needs to execute a given job, so there is no need to know the execution status and execution results with other job execution devices 2. For this reason, there is no need to exchange a synchronization signal for transferring information such as the job execution status and execution result, and it is possible to eliminate a delay for the synchronization and a load on the network. Furthermore, since the job execution apparatus 2 issues the job execution status to the job control apparatus 1 as an event 53 with a small amount of information, centralized control and management of the job can be executed while reducing the communication load on the job control apparatus 1. .

  2 and 9, the operation of the job execution status monitoring process of the job execution monitoring system according to the present invention will be described. The job monitoring unit 31 of the job monitoring terminal 3 issues an event request to the differential event management unit 12 of the job control device 1 (step S42). At this time, the job monitoring unit 31 may issue an event request periodically or arbitrarily issue an event request according to a command from an input device (not shown) operated by a monitor. Upon receiving the event request, the differential event management unit 12 extracts the differential event 56 (for example, the differential event 56 corresponding to the job network ID included in the event request) from the differential event D / B 103 based on the event request, and monitors the job. It transmits to the job monitoring part 31 of the terminal 3 (step S44). The job monitoring unit 31 transfers the difference event 56 received by the job monitoring information output device 31 to the job monitoring information output device 34 and displays the status display of the execution status of the job network 51 displayed on the job monitoring information output device 34. Update.

  With reference to FIGS. 2 and 10, the operation of the job execution history acquisition and display processing of the job execution monitoring system according to the present invention will be described. The history management unit 32 of the job monitoring terminal 3 issues a history information request to the job network history search unit 13 of the job control device 1 (step S52). At this time, the history management unit 32 may issue a history information request periodically, or may arbitrarily issue a history information request according to a command from an input device (not shown) operated by a supervisor. Upon receiving the history information request, the job network history search unit 12 receives a job history 58 from the job network D / B 102 (for example, an end code that is detailed information other than the job status event, standard output, standard error output, job execution start) Time, execution end time, job execution device name, etc.) are extracted and transmitted to the history management unit 32 (step S56). The history management unit 32 transfers the received job history 58 to the job monitoring information output device 34, and updates the history display of the job network 51 displayed on the job monitoring information output device 34 (step S58).

  Referring to FIG. 12, a conceptual diagram of a display screen of the job monitoring information output device 34 according to the present invention is shown. The display screen of the job information output device 34 is preferably a monitoring window 341 that displays the execution status, execution status of the job network 51 being executed, execution start time and end time of the job, and the like. And a monitoring window 342 that graphically displays the execution status of the job network 51 such as a flow. The monitoring window 341 displays a job network ID for identifying the job network 51, a job execution status, and job execution start and end times in association with each other. The status is preferably displayed in different colors, such as normal end green, abnormal end red, and running yellow. In the monitoring window 342, the currently executing job network 341 is displayed as a flow, a square frame indicating each job is assigned a job ID for identifying the job, and the square frame indicates normal end, abnormal end, and executing. The execution status is displayed. This display may also be color-coded in the same manner as the monitoring window 341. The monitoring window 342 may display a job network that has already been executed or a job network that is scheduled to be executed, in addition to the job network that is being executed, by a signal from an input device (not shown) that is operated by the monitor.

  As described above, since the job monitoring terminal 3 acquires the differential event 56 and the event history 58 periodically or when necessary by the monitor, the number of accesses to the job control apparatus 1 and the amount of transfer information can be limited. Therefore, it is possible to reduce the load on the job control device 1 and the network connecting the devices.

  With reference to FIG. 13, the operation at the time of job execution error in the job execution monitoring system according to the present invention will be described. In the job execution device 2, when the job 52 cannot be executed, or when a predetermined time (not shown) set in the job network 51 is exceeded, the job execution device 2 An abnormal event 54 is transmitted (step S62). The job network control unit 15 transfers an abnormal event to the job integrated monitoring terminal 4 (step S64). The abnormality information control unit 41 of the integrated monitoring terminal 4 that has received the abnormal event 54 transmits the abnormal event to the integrated monitoring information output device 42 and the warning device 43. Referring to FIG. 15, the integrated monitoring information output device 42 displays the integrated monitoring information based on the received abnormal event. The integrated monitoring information includes the event type, job ID, and event content of the received abnormal event 54. The warning device 43 generates an alarm by sounding a siren and turning on a red light. For example, when job C ends abnormally, the siren of the warning device 43 sounds, and the event “alarm”, job ID “job C”, and event “abnormal end” are displayed on the integrated monitoring information output device 42. The abnormality information control unit 41 of the integrated monitoring terminal 4 transmits an end event 55 received from the job control apparatus 1 to the integrated monitoring information output apparatus 42 and displays the end information. At this time, in the case of normal end, the event type is displayed as “information”, the job ID is displayed as “job A”, for example, and the event is displayed as “normal end”.

  In this way, it is possible to easily and timely grasp a job in which an error has occurred during execution and its contents. Further, since the monitor does not always need to visually check and confirm the integrated monitoring information output device 42 and can check the abnormality only when there is an abnormality, the burden and cost of the monitoring person can be reduced.

  Further, since only important events among the events 53 of the execution status of the job 52 are transferred to the integrated monitoring terminal 4, the monitor need only monitor the integrated monitoring terminal 4.

  Referring to FIG. 16, in the job execution monitoring system according to the present invention, an operation of changing the job execution apparatus 2 when a job execution error occurs is shown.

  As shown in FIG. 6C, when job A53-1 is executed, "job execution device 2-1" is assigned as the job execution device, and "job execution device 2-2" is assigned as the spare job execution device. ing. When an error occurs in the job execution device 2-1 that has been executing the job A53-1, the job execution device 2-1 transmits an abnormal event 54 to the job control device 1 (step S72). The job control apparatus 1 transfers the job A53-1 to the job execution apparatus 2-2, which is a backup job execution apparatus, as the execution destination of the job A53-1 (step S76). The job execution device 2-2 executes the received job A53-1 (step S78). If an error occurs during execution of job A53-1 in the job execution device 2-2, an abnormal event 54 is transmitted to the job control device 1 (step S80). Upon receiving the abnormal event 54, the job control apparatus 1 searches for a spare job execution apparatus. If there is no spare job execution apparatus assigned, the job control apparatus 1 abnormally terminates the next job, for example, job B52-2 and job C52-3. Are transmitted to the job execution device 2-2 and the job execution device 2-3 assigned to each of them (steps S82 and S84). The job execution apparatus 2-2 that has received the job B 52-2 executes the received job B 52-2, and the execution apparatus 2-3 that has received the job C 52-3 executes the received job C 52-3 ( Step S86).

  In this way, by defining a spare job execution device in the job network and switching the execution destination of the job 52 using the abnormal event 54 as a trigger, job execution errors can be immediately and centrally remedied.

  As described above, the job execution monitoring system according to the present invention can be constructed with an open system such as a UNIX (registered trademark) server instead of a large-sized computer such as a mainframe. Further, since only the important warning is notified to the integrated monitoring terminal 4 and is notified by the warning sound or the rotation of the warning lamp, it is only necessary to be near the integrated monitoring terminal 4 and execute a large number of jobs. Eliminates the need to monitor all results visually. For this reason, the cost of the supervisor can be reduced. Further, the job 52 and the job network 51 are aggregated in one job control apparatus 1 and distributed to a plurality of job execution apparatuses 2-1 to n connected to the network and executed. For this reason, all job execution statuses and execution results can be consolidated, controlled, and managed in one job control apparatus 1, and system management becomes easy.

  The embodiment of the present invention has been described in detail above, but the specific configuration is not limited to the above-described embodiment, and changes within a scope not departing from the gist of the present invention are included in the present invention. . In the present embodiment, the job network control unit 15 transfers the abnormal event 54 to the integrated monitoring terminal 4 via the event transmission unit 11 when the job 52 execution error occurs. You can send it. At this time, the abnormality information control unit 41 that has received the alarm event causes the alarm device 43 to generate an alarm based on the alarm event. Thereby, the amount of information between the job control device 1 and the integrated monitoring terminal 4 can be further reduced.
