19.7.1 Starting the N-to-1 recovery system
This subsection describes the points to be considered during system startup when you are using the N-to-1 recovery system based on the HA monitor, and also describes the procedure for starting the system.
- Organization of this subsection
(1) Points to consider when starting the system
The points to be considered during system startup when you are using the N-to-1 recovery system based on the HA monitor are as follows:
-
The HA monitor deployed on the executing node and standby node host starts simultaneously with the OS.
-
Start Management Server if you have not yet started. For details on how to start Management Server, see 4.1.1 Procedure for starting a system and 4.1.2 Methods of starting a system in the uCosminexus Application Server Management Portal User Guide.
(2) Procedure for starting the system
The following is the procedure to start the system when you are using the N-to-1 recovery system based on the HA monitor:
-
In the standby node host, execute the monbegin command corresponding to each executing node N number of times.
# monbegin server-identification-name
In the underlined part, specify the identification name of the executing node server specified in the operand alias in the servers file.
By doing this, the standby node recovery server starts monitoring the executing nodes.
-
In each of the N number of executing node hosts, execute the monbegin command, and start the Administration Agent of each executing node host.
# monbegin server-identification-name
In the underlined part, specify the identification name of the server specified in the operand alias in the servers file.
By doing this, the Administration Agent of each executing node host starts.
- Important note
-
When you have not specified the settings for batch start of the logical servers in the management domain during startup of Management Server, start the logical server of each executing node host. When you have specified the settings for batch start of the logical servers in the management domain during startup of Management Server, you need not start the logical servers manually. For starting the logical servers, see 4.1.2 Methods of starting a system in the uCosminexus Application Server Management Portal User Guide.
- Reference note
-
For details on defining the servers file (setting the server environment with the HA monitor), see 19.5.6 Setting the server-compliant environment.
