Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control system in which supervisory control of a plurality of online systems using a plurality of CPUs is performed by a single surveillance terminal.

[0002]

2. Description of the Related Art In a conventional supervisory control method for a plurality of online systems using a plurality of CPUs, when displaying a message output from each online system on a screen,
One online system corresponds to one screen. Also each C
In the connection method between the PU and the monitoring terminal, the number of sessions from the monitoring terminal is one, and one CPU is used for the active online system and one CPU is used for the standby online system. It is common to provide a monitoring terminal for each CPU. Commands are input to each online system from a terminal connected to the CPU on which the online system is operating.

As a known document for monitoring a plurality of online systems using a plurality of CPUs with a single monitoring terminal, for example, there is a system using a common bus as disclosed in Japanese Patent Laid-Open No. 55-3018.

[0004]

In the above prior art, it is necessary to set a monitoring terminal for each CPU, and the monitoring of messages output from each online system and the input of commands are performed for each monitoring terminal. I had to do it. When the current online system fails, when switching to the standby online system, the message display screen output from each online system or the monitoring terminal also switches, and the operator's correspondence is difficult, and the command input terminal has also switched. However, there is a possibility that an operation mistake may occur. Further, session switching between each CPU and the monitoring terminal occurred.

In the connection method using the common bus, the session switching does not occur even when the online system is switched, but there is a problem that even if the bus fails in one place, the monitoring processing of all online systems cannot be performed in some cases. there were.

According to the present invention, a plurality of online systems can be monitored on one display screen of one monitoring terminal, and it is possible to simplify the operation such that a command can be input to each online system only once. It is also an object of the present invention to provide an online system with a simple operation in which the display screen of the message or the terminal is not switched even when the online system fails.

[0007]

In order to solve the above problems, in a supervisory control system for a plurality of online systems using a plurality of CPUs, each CPU adds an identifier of each online system to a message transmitted to a monitoring terminal. The monitoring terminal is divided into a plurality of screens of the display device to be connected, the divided screens are associated with the respective online systems, the online system name is determined based on the identifier of the message received from the CPU, and the corresponding unit is provided. It is provided with a means for displaying a message on a split screen. Also, each CP
The connection between U and the monitoring terminal is based on a system using multi-session, which enables simultaneous transmission to each online system with one input.

[0008]

By using the above means, it is sufficient to monitor the messages output from each online system by looking at the predetermined split screen of one screen, and when the current online system fails, the standby online system can be used. Even if the message is switched, the message display screen and the monitoring terminal are not switched, and the message is output to the same split screen as before the failure. Further, the command input to each online system may be performed from the same monitoring terminal, and therefore the operation can be simplified.

Further, when the online system switching occurs, the switching of the session between each CPU and the monitoring terminal does not occur, so that the reliability is improved.

Current online system A on the CPU X1 side
When the message A18 is output from 11, the CPUX side analysis program 15 receives the message (50
1). The CPUX side analysis program 15 judges which job is output from the online system A or the online system B based on the job name added to the message A18 (502), and the conversion table According to 17, it is converted into an identifier corresponding to each online system (503). The job name of message A18 is J
Since it is OBA and corresponds to the online system A, it is converted into the identifier a. Next, the identifier a converted from the job name
The message B19 added with is sent to the monitoring terminal 5 via the line 3 connected by multisession (50
4). The message transmitted to the monitoring terminal 5 is, for example, system startup, external service start, failure status report, or the like. When the monitoring terminal 5 receives the message by the transmission / reception program 22 (505), the control is passed to the monitoring terminal side analysis program 6. The monitoring terminal side analysis program 6 is
The identifier added to the message is analyzed to determine whether the message is output from the online system A or the online system B,
It is output to the corresponding display screen area (506). The display screen is divided into a plurality of areas and is associated with each online system. Here, it is output to the display screen area 7 for online A.

Similarly, for the message output from the active online system B13 on the CPUY2 side, an identifier corresponding to the online system B is added to the message by the CPUY side analysis program 16, and the message is sent via the line 4 connected by the multi session. And transmitted to the monitoring terminal 5. The monitoring terminal side analysis program 6 analyzes that the identifier corresponds to the online system B and outputs it to the online system B display screen area 8.

A case where a command is transmitted from the monitoring terminal 5 to each online system will be described with reference to FIGS.
Input device 1 when inputting commands to each online system
When a command is input from 0, control is passed to the monitoring terminal side analysis program 6 and the input command is output to the command input display screen area 9. The monitoring terminal side analysis program 6 determines the job name in the message details of the message 20 output at the start of each online system and which CPU the message is output from the line to which the message is transmitted, and the operating status Management table 2

The data transmission / reception program 22 establishes a session with each CPU by transmitting a session start command to each CPU via an input / output port dedicated to each CPU.

When the active online system A11 and the active online system B13 are operating normally,
Since the active online system A11 is operating under the CPUX1 and the active online system B13 is operating under the CPUY2, the input command is output to the command input display screen area 9 by the monitoring terminal side analysis program 6,
A command to the online system A is transmitted to the CPU X1 and a command to the online system B is transmitted to the CPU Y2 based on the operation status management table 21.

Next, the monitoring method will be described by taking as an example the case where the active online system A11 becomes a failure and is switched to the standby online system A14. At this time, the message output from the standby online system A14 is C
Although it is output from PUY2, even at this time, the CPUY-side analysis program 16 determines from the job name that the online system name is online system A, and the identifier a corresponding to online system A is added to the message. It is transmitted to the monitoring terminal 5 via the line 4 connected by. Since the identifier a in the monitoring terminal side analysis program 6 corresponds to the online system A,
Output to the display screen area 7 for the online system A.

In the monitoring terminal side analysis program 6, as in the case described above, the job name in the message details of the message 20 output at the start of each online system, and which CPU is output from the line to which the message is transmitted. It is determined that the message is a valid message and the job name and CP in which the online system is operating in the operation status management table
The information of U is set, and which CPU and which online system is currently operating are managed. Since the standby online system A14 is operating under CPUY2 and there is no online system operating under CPUX1, in the operating status management table, JOBA is CP
Corresponds to UY.

When a command is sent from the monitoring terminal side to the online system A, the command input from the input device 10 is output to the command input display screen area 9 by the monitoring terminal side analysis program 6, and the operating condition management table is referred to. It analyzes that the online system A is currently operating on CPUY2 and sends it to CPUY2.

Next, the active online systems A11 and B
13 both become obstacles, standby online system A1
The monitoring method will be described by taking as an example the case of switching to 4 and B12. At this time, the online system A message is CP
Although the message output from UY2 and the message from the online system B is output from CPUX1, the analysis program of each CPU analyzes the output source job name and adds the corresponding identifier, so that the monitoring terminal side analysis program 6 uses the identifier. Is analyzed, the online system A display screen area 7 is displayed if the online system A is supported, and the online system B is displayed if the online system B is supported.
