uCosminexus Application Server, Operation, Monitoring, and Linkage Guide
You execute the following settings for a cluster:
Code a script file for starting and stopping Application Server in the executing node using VBScript. Use the same script file in each node of the executing node, and allocate the script file to the same path.
The script file uses the general-purpose script as it is. For an example of the general-purpose script file, see (2) Example of a general-purpose script file of the executing node.
This subsection describes the monitoring targets and the monitoring methods for N-to-1 recovery systems.
The monitoring target for 1-to-1 node switching systems of Application Server is as follows:
The node switching is executed when Administration Agent ends.
You monitor the availability of processes of Administration Agent. You monitor the following process:
The following example describes a general-purpose script file used in the executing node of an N-to-1 recovery system:

With the general-purpose script file of the executing node, you change variable values as and when required. For details on the variables defined in the general-purpose script file, see (a) Variables of the general-purpose script file.
Also, with the general-purpose script file of the N-to-1 recovery system, one script file is referenced from multiple virtual servers. Because of this, use a private property so that the general-purpose script file can reference the settings of each server. For details on the private property specified for each virtual server, see (3) Settings of private property.
With the general-purpose script file of the executing node, change variable values as and when required. Change the values of the variables described in the following table.
Table 19-2 Variables of the general-purpose script file of the executing node (In N-to-1 recovery system)
Variable name | Contents |
---|---|
oMngHost | Host being operated by Management Server |
oUser | Login ID for logging to Management Server |
oPass | Password for logging to Management Server |
Set up a private property for each virtual server. The following table describes the private properties required for the general-purpose script file.
Table 19-3 Private properties required for the general-purpose script file
Private property | Contents (Example) |
---|---|
ServerName | J2EE server name Specification example: MyServer |
StatusPath | Status path of the in-process OTS Specification example: I:\otsstatus |
IPAddress | IP address of the virtual server Specification example: 172.16.12.31 |
HostName | Virtual server name Specification example: Server1 |
The private properties are set up in the cluster command. For details on the cluster command, see the documentation of the OS that is being used. The following example describes the settings of a private property that uses the cluster command:
cluster res Script1 /priv ServerName=MyServer cluster res Script1 /priv StatusPath="I:\otsstatus" cluster res Script1 /priv IPAddress=172.16.12.31 cluster res Script1 /priv HostName=Server1 cluster res Script2 /priv ServerName=MyServer cluster res Script2 /priv StatusPath="J:\otsstatus" cluster res Script2 /priv IPAddress=172.16.12.32 cluster res Script2 /priv HostName=Server2 cluster res Script3 /priv ServerName=MyServer cluster res Script3 /priv StatusPath="K:\otsstatus" cluster res Script3 /priv IPAddress=172.16.12.33 cluster res Script3 /priv HostName=Server3 cluster res Script4 /priv ServerName=MyServer2 cluster res Script4 /priv StatusPath="L:\otsstatus" cluster res Script4 /priv IPAddress=172.16.12.34 cluster res Script4 /priv HostName=Server4 |
