10.2.1 Before installation and setup

(a) Cluster system

Make sure that the following conditions are satisfied:

• The cluster system is controlled by cluster software.

• Settings are made so that the starting and stopping of Performance Management used on a logical host are controlled by cluster software.

Also, disable the following forms of error reporting:

Error reporting by Dr. Watson in Windows Server 2003 (on the executing and standby nodes)

The system might be unable to fail over if an application error message box is displayed in Dr. Watson. For this reason, you need to prevent Windows from reporting errors in message boxes.

Note that suppressing error notification might hinder attempts to acquire information when an application error occurs.

1. To enable Dr. Watson, enter drwtsn32 -i at the command prompt.

2. Dr. Watson is installed as the default application debugger.

3. From the Start menu, choose Run.

4. Enter drwtsn32 in the text box, and then click OK.

5. In the Dr. Watson dialog box, clear the Visual Notification check box.

6. Click OK.

Reporting errors to Microsoft (on the active and standby nodes)

If an application error occurs in Windows, a dialog box for reporting the error to Microsoft sometimes appears. If this dialog box is displayed, a failover might not be performed, therefore, you need to suppress such error notification.

In Windows Server 2003:

1. In the Control Panel, choose System.

2. On the Advanced page of the System Properties dialog box, click Error Reporting.

3. In the Error Reporting dialog box, select the Disable error reporting radio button, and then clear the But notify me when critical error occur check box.

4. Click OK.

In Windows Server 2008:

1. In the Control Panel, choose System and Security, Action Center, and then Maintenance.

2. Under Check for solutions to problem reports, click Settings.

3. In the Choose when to check for solutions to problem reports dialog box, select Never check for solutions.

4. Click OK.

In Windows Server 2012:

1. In the Control Panel, choose System and Security, Action Center, and then Maintenance.

2. Under Check for solutions to problem reports, click Settings.

3. In the Windows Error Reporting Configuration dialog box, select I don't want to participate, and don't ask me again.

4. Click OK.

(b) Shared disks

Make sure that the following conditions are satisfied:

• Each logical host has a shared disk, and the disk can be taken over by from the executing node by the standby node.

• Shared disks are physically connected to each node via Fibre Channel or SCSI. Configurations in which the shared disk is a network drive or disk replicated over a network are not supported.

• When a failover occurs, if some processes are still using the shared disks, make sure it is still possible to force shared disks offline via cluster software or by other means and perform a failover.

• If multiple Performance Management programs are executed on a single logical host, make sure the directory names for the shared disks are the same. For Store databases, make sure the storage destination can be changed to allow storage in a different directory on the same shared disk.

(c) Logical host name and logical IP address

Make sure that the following conditions are satisfied:

• There is a logical host name and corresponding logical IP address for each logical host, and switching from the executing node to the standby node can be performed.

• The logical host and logical IP address are set in the hosts file and on the name server.

• If using a DNS a logical host name is specified without a domain name, instead of by using a FQDN.

• Each physical host name and logical host name is unique within the system.

  Important note

  Regarding logical host names:

  • Do not use a physical host name (a host name displayed using the hostname command) for a logical host name. Otherwise, normal communication processing might be prevented.

  • Logical host names must consist of from 1 to 32 bytes alphanumeric characters.

  • localhost, an IP addresses, or a hyphen (-) cannot be used for a logical host name.
