Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notification message queuing system for processing a notification message generated asynchronously in an online system. [Prior Art] Conventionally, in an online system, a message table is provided in a message processing unit, and a processing timing of a notification message is determined. If the processing timing is not a processing timing, the message is registered in the message table. The table is searched to determine the presence / absence of a waiting message and the timing of processing. If the timing is processing, the waiting message is processed. [Problems to be Solved by the Invention] Usually, a plurality of message processing units exist for each function.
Therefore, in the conventional notification message waiting process described above, a plurality of message tables are required, and a large capacity of the main storage device is required. In addition, the message processing unit requires notification message queuing processing for several message processing units, so that the number of development steps is increased. [Means for Solving the Problem] The notification message queuing processing device of the present invention includes a message processing unit provided for each function of a notification message, a notification message requiring queuing, and a re-notification time of the notification message. A message table stored in association with a message processing unit that refers to the message table at regular time intervals and returns the notification message whose re-notification time has expired to a message processing unit that has registered the notification message. The message processing unit, when receiving a notification message from a peripheral device constituting the online system or the waiting processing unit, if the other notification message is not being processed, processes the received notification message; If a message is being processed, a certain Characterized in that assigned the serial snooze time is intended to be registered in the message table. [Operation] Since the message table and the queuing processing unit are shared with the message processing unit, the capacity of the main storage device can be reduced, and the number of development steps of the message processing unit can be reduced. Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a main configuration of an embodiment of an online system to which a notification message queuing system of the present invention is applied. FIG. 2 is a flowchart showing a processing procedure of message processing units 3, 4, and 5. FIG. 3 is a flowchart showing a processing procedure of the waiting processing unit 7. This online system is a host computer 1
(Central processing unit and main memory), console 8 connected thereto, file 9 storing data required for notification message processing, printer 10 for outputting the result of notification message processing in detail, and communication device 11 of terminal. It is configured. The host computer 1 includes an operation management unit 2, message processing units 3, 4, 5 and a message table 6 queuing processing unit 7. The operation management unit 2 manages the entire system, and sends a request notification message from the console 8, a failure and recovery notification message from the communication device 11, and an online operation start and end notification message to a message provided in advance for each function of the notification message. Output to the corresponding message processing unit among the processing units. Message processing units 3, 4, 5
As shown in FIG. 2, upon receipt of the notification message (step 20), the device determines whether or not it is processing the previously received notification message (step 21). The message is registered in the message table 6 with a fixed re-notification time (step 22), and if not being processed, the received notification message is processed (step 23). In the message table 6, the message processing units 3, 4, 5
However, since a notification message that has occurred previously is being processed, a notification message that cannot be processed and needs to be registered is registered. Table 1 shows an example of the registered contents of the notification message in the message table 6. The column of the message processing unit that registered the notification message in the message table 6 is stored in the column of the registration source message processing unit. In the message re-notification time column, the time from registration of a certain message to re-notification is stored in seconds. As the message re-notification time, a certain time may be set or a time considering the priority of the notification message may be set. The valid display field shows the valid / invalid status of the message.
Indicates invalid, "1" is displayed at the time of registration, and "0" is displayed after re-notification. The message contents column stores all the contents of the message. For example, in Table 1, the content is "ABC ..."
The message is registered by the message processing unit 4 and re-notification is 5 seconds, indicating that the message is valid. Also,
Since the message with the content "ZYX ..." has a message re-notification time of 0 and a valid display of "0", it indicates that the re-notification has been completed. The queuing processing unit 7, as shown in FIG.
The message table 6 is searched at regular intervals (step
30), refer to the valid / invalid display of the message (step 31), and if invalid, proceed to the search for the next waiting message; if valid, check the re-notification time (step 31).
32). Here, if the re-notification time is not 0, 1 is subtracted from the re-notification time (step 35), and the process proceeds to the search for the next waiting message. If the re-notification time is 0, the message content is transmitted to the registration source message processing unit (step 33), the valid / invalid display is set to "0" (invalid) (step 34), and the message is deleted from the message table 6. I do. [Effects of the Invention] As described above, the present invention can save the main storage device by sharing the message table between the message processing units, and also share the queuing processing unit between the message processing units. This has the effect of reducing the number of development steps for the message processing unit.
