ログラムを起動する。In the information processing system of the present invention, the active central processing unit and the standby central processing unit are connected by an online adapter, and communication means is provided between the active service processor and the standby service processor. In the standby system, the same online transaction job program as in the active system is placed in a standby state immediately before the start of execution, and the central processing unit in the active system uses the monitoring program means to the central processing unit in the standby system via the online adapter. Communication is performed, and the central processing unit of the standby system monitors the reception of the communication within a fixed time, and if the communication is not received within the fixed time, the active processor of the active system goes through the service processor of the standby system. A system complete stop request is issued, and the service processor of the active system sets the central processing unit of the active system to the clock stop state, Serial spare system central processing unit activates the online transaction job program of the backup system in the standby state.
次に，本発明について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.

を編集して送信する。Using the online transaction job program (OLTP) 11 on the main storage device 1, the CPU 2 receives the electronic message input from the communication processing device 10 via the operating system (hereinafter abbreviated as OS) 13 and the magnetic disk processing device 8 The data of the magnetic disk device 9 read via the data and the data in the electronic message are merged and processed. Then, the processing result is written on the magnetic disk device 9 for updating, and the processing result is edited and transmitted to a terminal (not shown) via the communication processing device 10.

直前の待機状態にしている。In the standby system, the batch job 34 is executed under the control of the operating system OS33. Furthermore, the monitoring program 32 is started under the control of the OS 33, and the monitoring program 32
32 loads the same online transaction job program OLTP31 as the active system, temporarily opens the file name on the magnetic disk unit 9 on OLTP31, temporarily opens the access path to the terminal on OLTP31, and executes OLTP31 It is in the last standby state.

事を監視する。On the other hand, the active OLTP11 notifies that the OLTP11 itself is operating normally at 4-second intervals. Using the monitoring program 12 that received this notification, the CPU 2 sends an “I AM ALIVE” “(I AM ALIVE)” to the standby CPU 4 via the online adapter 5.
A heartbeat message "Alive" is sent. The CPU 4 uses the monitoring program 32 to monitor that it continues to receive heartbeat messages at intervals of 5 seconds or less.

Suppose 13 is stalled. OLTP11 will not be scheduled and heartbeat messages from CPU2 will not be communicated. For this reason, the standby CPU 4 does not receive the heartbeat communication even after 5 seconds elapses, and therefore detects a timeout and detects that an abnormality has occurred in the active system.

ブを停止して，予備系がオンライントランザクション処
理を現用系の処理能力と同じで実行する。Using the monitoring program 32, the CPU 4 issues a complete stop request for the active system to the SVP 7. SVP7 issues a complete stop request for the active system to SVP6, and SVP6 sets CPU2 to the clock stop state. After that, SVP7 notifies the monitoring program 32 that the active system has been completely stopped. The monitoring program 32 issues an execution instruction request to the OLTP 31, and the OLTP 31 in the standby state can re-receive the message from the terminal in a short time. Then, the batch job is stopped, and the standby system executes online transaction processing with the same processing capacity as the active system.
以上説明したように，本発明は現用系のCPU2と予備系

るという効果がある。As described above, according to the present invention, the CPU 2 of the active system and the CPU 4 of the standby system are connected by the online adapter 5, and the SVP6 is used.
By providing the communication means between SVP7 and SVP7, there is an effect that the system construction cost can be reduced, and if the active system goes down, the CPU2 can be completely stopped and the standby system can resume processing reliably and in a short time. .
