Chapter 8: General Customization Process This chapter explains the general process to customize NEC ExpressCluster SRE to monitor and restart arbitrary application services. Command Reference The following section explains the functionality and usage of the ARMLOAD and ARMKILL commands (used in start.bat and stop.bat scripts respectively) to monitor and restart arbitrary services. ARMLOAD Starts up a service. If a fault occurs in the started service, the service is restarted.
/S Specifies that the entity to be started up is a service. This parameter is mandatory. /A Indicates that ExpressCluster will not identify it as an error if the service has already started and is running. Please specify this parameter in case the start up type of the service is [AUTOMATIC] (in Settings-> Control Panel -> Administrative Tools -> Services) /WAIT time Used to specify the time in seconds required for waiting for the completion of service startup.
ARMKILL Terminates the service that was started up by using the ARMLOAD command. Usage: ARMKILL watchID [/C | /T time] Parameters: watchID This is the monitoring ID of the service to be terminated. For this ID, use the one that was specified when the service was started up by the ARMLOAD command. /C Cancels the monitoring of the service but does not terminate the service. This parameter can be omitted. If it is omitted, the service is terminated.
Sets the wait time for waiting until the service stops completely. The range that can be specified is from 0 to 3600 seconds. If 0 is specified, the wait time is unlimited. This parameter can be omitted. If it is omitted, the wait time is 40 seconds. Also, this parameter cannot be specified at the same time as the /C parameter. As an example, the following section explains the steps required to customize the scripts for monitoring an arbitrary service (e.g. Telnet service).
Step 2: Select the Reference and Change (C) radio button. Also check the Stop the group(S) check box and Click OK.
Step 3: Select the Scripts tab and highlight the start.bat script.
Step 4: Click on the Edit button. This opens the start.bat file in notepad. Edit the start.
Step 5: Save the file and click OK. Step 6: Highlight the stop.bat script similar to Step 3 above. Step 7: Click on the Edit button. This opens the stop.bat file in notepad. Edit the stop.
Step 8: Save the file and click OK.
Step 9: Start the group on the server. Right click on the Failover Group and select Start Group (E) to start the group on the server.
Click OK on the screen below: The Failover Group icon should be Green and all the resources should be Online as below: 119
Please verify that the Telnet service starts successfully on the server. In case the Telnet service terminates, it is automatically restarted after 5 seconds. If it terminates more than 2 times in 1 hour, the server is rebooted automatically.
Appendix A: Modifying IP Addresses You could either change the default IP addresses assigned to the Loopback Adapter of the server. Please ensure that you identify two static IP addresses in different network segments that are unique on the network. This requirement is mandatory. The first IP address is used to register the Cluster Server with the Manager and the second IP address is used as the Primary Interconnect IP address. The steps below change the default IP address 10.123.187.1/255.255.255.0 to 20.
Use Start-> Settings-> Control Panel-> Network and Dial up Connections.
Step 2: Select Internet Protocol (TCP/IP) and click the Properties button: 123
Select Internet Protocol (TCP/IP) and click the Properties button: 124
Step 3: Change the IP Address to it: IP: 20.20.20.
Step 4: Click on the Advanced button, select 192.168.93.
Step 5: Change the second IP Address to IP: 131.241.74.
Step 7: Click OK on the following screen: 128
This completes the steps to change the default IP addresses.
