5.12.6 Notes about using a cluster system
The following notes apply when a cluster system is used:
-
If acquisition of Dr. Watson's log file has been set in the OS, failover will not occur. To run Asset Console in a cluster system, specify the settings so that Dr. Watson's log file is not acquired.
-
When you install or uninstall Asset Console, use the Cluster Administrator to place the service resources of World Wide Web Publishing Service offline. After that, stop World Wide Web Publishing Service from Services, which is displayed by selecting Administrative Tools from Control Panel. If you start the installer or uninstaller while the service resource is online, failover might occur depending on the resource settings, or the installer or uninstaller might hang up or terminate abnormally.
-
If you change server setup settings, the settings specified at the executing server are not applied to the standby server, regardless of whether the service resource is online or offline. Make sure that each server has the same server settings.
-
If IIS6.0 or later is used, World Wide Web Publishing Service or World Wide Web Publishing on the standby server must be stopped.
-
After you have set up for a cluster system environment, do not change Logical host name and Execution host name. If these settings are changed, the cluster functions will not work normally with Asset Console. To change the logical host name and execution host name, you must re-create the asset management database. For details about how to rename logical hosts, see E.3 Renaming the host. For details about how to rename the executing host, see (1)(b) How to rename the executing host.
-
When a failover occurs, World Wide Web Publishing Service (or World Wide Web Publishing) that has stopped must be started on the standby server. Therefore, World Wide Web Publishing Service on the standby server must be stopped before a failover occurs. For example, you can stop World Wide Web Publishing Service when Microsoft Internet Information Services on the standby server is offline by writing the code shown below for the Offline function in Clusweb.vbs (or Clusweb7.vbs). Using this setting, you can automate stoppage of World Wide Web Publishing Service.
Coding example
... Function Offline( ) Dim objWmiProvider Dim objService set objWmiProvider = GetObject("winmgmts:/root/cimv2") set objService = objWmiProvider.get("win32_service='w3svc'") StopWebSite() Offline = true objService.StopService() End Function ...

(1) How to change the logical host name and execution host name
This subsection describes how to rename the logical host and executing host.
(a) How to rename the logical host
For details about how to rename logical hosts, see E.3 Renaming the host.
(b) How to rename the executing host
Before you rename the executing host, stop all Asset Console services, commands, and tasks on the asset management server.
To stop Asset Console services, stop the following services in the listed order:
-
World Wide Web Publishing Service or World Wide Web Publishing
-
Asset Console commands and tasks
To run Asset Console after having changed the executing host name, start the services in the reverse of the order in which they were stopped.
To rename the executing host:
-
Stop the database.
For details about how to stop the database, see E.4(2) Stopping the database.
-
Use a text editor to open the pdutsys file that is stored in Asset-Console-installation-folder\aimdb\conf.
-
In the pdutsys file, change host-name in set pd_hostname=host-name.
-
Rename the OS host.
-
Restart the OS.
