Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system that executes data processing while outputting a message to a terminal.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system capable of outputting a message to a terminal at a high speed by reducing the number of times of access.

In a data processing system that executes predetermined data processing while interacting with the user, for example, performing a failure judgment according to an AI tool, a process of sequentially displaying messages and responding to the user via a display screen Will be executed. In such a message output process, it is necessary to take measures to output the message at high speed in response to an increase in the number of messages to be output.

[Conventional technology]

Conventionally, a message is directly embedded in a program for executing data processing. However, in such a conventional technique, as shown in FIG. 5 (a), there is a problem that the program size becomes large and the virtual storage area is squeezed, and even when only the message is corrected, There is a problem that the program must be corrected and a program correction step as shown in FIG. 5 (b) must be executed.

In order to solve such a problem, messages are separated from a program, stored in a data set on an external storage device, necessary messages are read from this data set via a message access program, and output to a terminal. A method of adopting a configuration of doing so was conceived.
FIG. 6 shows the configuration of this prior art. According to this conventional technique, it is possible to solve the problem that the program size is increased, and it is also possible to correct only the message without correcting the program.

[Problems to be solved by the invention]

However, in the latter prior art, there is a problem that the time until the message is output is lengthened by the time since the data set needs to be accessed each time the message needs to be output. . Therefore, there has been a problem that efficient data processing cannot be executed due to a delay in response from the terminal.

The present invention has been made in view of such circumstances,
An object of the present invention is to provide a new data processing system capable of outputting a message to a terminal at a high speed by reducing the number of I / O accesses.

[Means for solving the problem]

 FIG. 1 is a diagram illustrating the principle of the present invention.

In the figure, reference numeral 1 denotes a data processing apparatus main body equipped with the present invention;
Is an external storage device, 3 is a terminal, 4 is a data set stored in the external storage device 2, which is managed by a member unit in which messages are grouped, and 5 is a data processing execution unit. , A predetermined data processing is executed by outputting a message, a data set access unit 6 accesses the data set 4, and a message member expansion unit 7 in the main memory. To expand the message of dataset 4,
Reference numeral 61 denotes a member name specifying unit that specifies a member name to which the message requested to be output by the data processing execution unit 5 belongs. Reference numeral 62 denotes a read completion determining unit, which is a member name specified by the member name specifying unit 61. The message member reading unit 63 determines whether or not the message has been read by the message member expanding unit 7 based on the fact that the message has already been read. Reference numeral 63 denotes a message member reading unit. A message retrieving unit 64 for reading messages collectively from the data set 4 in accordance with the member unit and developing the messages in the message member expanding unit 7. 65 is a message output unit for retrieving a message with a message 3 is output.

[Action]

In the present invention, when there is a message output request from the data processing execution unit 5 according to the message identifier, the member name specifying unit 61 specifies the member name to which the message for which the output request belongs belongs from the message identifier. Upon receiving this member name, the read completion determining section 62 determines whether or not the message with this member name has been expanded in the message member expanding section 7. When it is determined that the message has been expanded in the message member expanding unit 7, the message member reading unit 63 does not perform any processing. On the other hand, when it is determined that the message has not been expanded, the message member reading unit 63 Instead, the message with the member name specified by the member name specifying unit 61 is expanded in the message member expanding unit 7.

In this way, when the member including the message whose output is requested is expanded in the message member expansion unit 7, the message search unit 64 extracts the message whose output is requested from the messages of the expanded members. The message output unit 65 searches and outputs the searched message to the terminal 3.

As described above, according to the present invention, a message that is likely to be output continuously is collectively expanded as a member in the main memory, and a message requested to be output is searched for and output therefrom. This means that the number of I / O accesses can be reduced, and messages can be output at high speed.

〔Example〕

 Hereinafter, the present invention will be described in detail with reference to examples.

FIG. 2 shows a system configuration of the data processing system according to the present invention. In the figure, 1 is the data processing device main body, 2a is DA
SD, 3a is a man-machine interface, 4a is a message data set, 20 is a CPU, 21 is a memory, 5a is a data processing program corresponding to the data processing execution unit 5 in FIG. 1, 6a
Is a message access program corresponding to the data set access section 6 in FIG. 1, and 7a is a message member expansion area corresponding to the message member expansion section 7 in FIG.

As in the prior art, the message data set 4a according to the present invention stores a message to be displayed on the display screen of the man-machine interface 3a in a data processing program.
Although it is managed separately from 5a, unlike the prior art, messages are managed in group members.

FIG. 3 shows the data structure of the message data set 4a. As shown in this figure, the message data set 4a groups “message A1” having the message identifier “MSGA001” and “message A2” having the message identifier “MSGA002” as messages belonging to “member A”, "Message B1" having the message identifier "MSGB001" and "Message B2" having the message identifier "MSGB002" are managed in a member unit in which messages are grouped, such as grouping as messages belonging to "member B". Each message is configured to display which member the message belongs to according to the code included in the message identifier.

How to combine a plurality of messages to be output is determined by the data processing of the data processing program 5a, for example, when the data processing is such as to execute a failure diagnosis of a computer system For example, it is conceivable to adopt a method in which messages presented for execution of a failure diagnosis are grouped as a member for each hardware resource type of a computer. In other words, if the hardware resources of a computer are classified into CPU, real memory, and I / O resources, one method is to manage the messages related to the production rules for each of these resources as one member. Is the way.

Next, the processing of the present invention will be described in detail with reference to the flowchart of FIG. 4 executed by the message access program 6a. Here, this flowchart shows that the message access program 6a has the data processing program 5a
It is called and executed when there is a message output request from.

Upon receiving a message output request from the data processing program 5a in accordance with the message identifier, the message access program 6a first converts the received message identifier into a member name in step 1 so that the message to which the output request belongs belongs. Find the member name. Specifically, the member name is specified from the symbol included in the message identifier. In the example of FIG. 3, when the message identifier “MSGA002” is received, the output request of the symbol “A” is output. The member to which a certain message belongs is specified as "member A".

Subsequently, in step 2, it is determined whether or not the message group having the obtained member name has already been read and has been expanded in the message member expansion area 7a. By the judgment of this step 2, the message member expansion area is already
If it is determined that the message data is expanded in the message member expansion area 7a, the process immediately proceeds to step 3 to search the received message data from the message group expanded in the message member expansion area 7a.

On the other hand, if it is determined in step 2 that the member name is different from that expanded in the message member expansion area 7a, the process proceeds to step 4 and the message group having the member name obtained from the message data set 4a is processed. Is read, and the message group with the read member name is expanded in the message member expansion area 7a in place of the message group with the member name that has been expanded so far. Then, the process proceeds to step 3, where the message member expansion area 7a
A process is performed to search the received message data from the message group expanded in. Here, the reason why the message group developed in the message member area 7a pertains to one member is to prevent the virtual storage area from being squeezed and to speed up the message data search processing.

By executing the processing in step 3 in this manner, the message access program 6a can search for the message data specified by the received message identifier. That is, in the example of FIG. 3, it is possible to obtain "message A2" specified by the received message identifier "MSGA002". The processing is terminated by outputting to the display screen of the machine interface 3a.

In this way, when there is a request to output a message included in the message group expanded in the message member expansion area 7a, the I / O access to the message data set 4a is not performed and the man-machine interface 3a is executed. Message can be output to

Although the illustrated embodiment has been described, the present invention is not limited to this. For example, the message identifier is not limited to directly describing the member name.

〔The invention's effect〕

As described above, according to the present invention, in a data processing system that outputs a message to a terminal according to a configuration that separates a program and a message, a message can be output with a small number of I / O accesses. Therefore, a message can be output to a terminal at a high speed.
