Chapter 1: Installation Prerequisites

This chapter describes the hardware and software prerequisites that must be satisfied before installing NEC ExpressCluster SRE.

Hardware Prerequisites

Server Model

The NEC Express5800/320Lb or NEC Express5800/320Lc server

Minimum Hard disk and Memory Capacity

Hard Disk: 77MB, Memory: 512 MB.

Software Prerequisites

Operating System

Windows 2000 Advanced Server with Service Pack 4 or Windows 2003

Enterprise Edition

SNMP

Please ensure that SNMP is installed on the server where NEC ExpressCluster

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.

The monitoring of the occurrence of fault continues until the application or service is terminated by the ARMKILL command. A fault means that the service is abnormally terminated.

Usage:

ARMLOAD watchID /S [/A] <mode> service-name

You can specify the followings as <mode>:

/R retry [/H hour] [/SCR] [/WAIT time] [/INT time]

Parameters: watchID

This is the ID used for monitoring. This ID is used for terminating the service by the ARMKILL command. The ID must be unique name within a cluster. IDs that begin with "NEC_" are reserved. They cannot be used by users. Set the ID using at most 255 single-byte alphanumeric characters. (It is case insensitive).

/R retry

Causes the application or service to be monitored and specifies the threshold value for the number of restart attempts at that time. The specification range is from 1 to 9.

/H hour

This is the time until the restart count is returned to zero for the service. The time can be specified in units of one hour. This parameter can be omitted. The specification range is from 1 to 24. If this parameter is omitted when the /R parameter is specified, the restart count is not reset.

/SCR

Indicates that when the monitoring service is restarted, it is restarted from a script.

This parameter can be omitted. If this parameter is omitted when the /R parameter is specified, the service is restarted.

109

Specifies that the entity to be started up is a service. This parameter is mandatory.

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. If this parameter is specified, the control is not returned until service startup is completed or until time does not exceed the specified waiting time. This parameter can be omitted. If the parameter is omitted, waiting for startup completion will not be executed. The specified range is from 0 to 3600. If

0 is specified, waiting time becomes infinity.

/INT time

Used to specify the time in seconds for re-starting a single service or a restart interval of the script. This parameter can be omitted. If the parameter is omitted, the re-start interval is 0 seconds. This parameter becomes effective when /R or/R,

/SCR option is specified. Specified range is from 0 to 3600. service-name

This is the name of the service that you would like to monitor. This is case

in-sensitive. e.g. If you would like to monitor the Telnet service, use Start-

>Settings-> Control Panel -> Administrative Tools -> Services and double click on Telnet service. Use the service name as tlntsvr as shown below:

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.

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. Also, this parameter cannot be specified at the same time as the /T parameter.

/T time

111

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).

Prerequisites

Please verify that the service you would like to monitor (in this case Telnet service) starts and stops normally using Control Panel -> Administrative tools ->

Services. If the Telnet service has started, please stop it using Control Panel ->

Administrative tools -> Services

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

20.20.20.1/255.255.255.0 and 192.168.93.1/255.255.255.0 to

131.241.74.17/255.255.255.0.
