This chapter provides general information to help you troubleshoot problems with Oracle Fail Safe installations and deinstallations. The following topics are covered in this chapter:
Overview of Problems With the FSCMD Command After an Upgrade
Verifying Whether Oracle Resources are Registered with Microsoft Windows Failover Clusters
Prior to release 3.4.2 the Oracle Fail Safe client directory was included in the system path environment variable, thus a full directory specification was not needed to start the FSCMD command. In 3.4.2 and later, the directory is no longer in the system path environment variable.
The FSCMD executable is located in ORACLE_HOME\FailSafe\Client directory, where ORACLE_HOME is the Oracle Fail Safe home directory. If you have not set your directory to ORACLE_HOME\FailSafe\Client, you must specify the full path when running the FSCMD command.
If you are running Oracle Universal Installer on a system that does not have Microsoft Windows Failover Cluster configured (such as a client system) and you try to install Oracle Fail Safe, then the installer will open an error window to display an error that states that the Oracle Fail Safe must be installed on a system running Microsoft Windows Failover Clusters. You must configure Microsoft Windows Failover Cluster prior to installing Oracle Fail Safe.
If such a message is displayed, do not continue with the installation. Click OK to go back to the installation windows and choose a Client Only installation. See Chapter 2 for more information about Client Only installation.
On successful installation and verification of Oracle Fail Safe, the Services Control Panel on each cluster node must include a new service entry named Oracle Fail Safe.
To verify the Oracle Fail Safe entry in the Services Control Panel:
The Oracle Fail Safe service is maintained by the Microsoft Windows Failover Clusters. On successful installation of Oracle Fail Safe on each cluster node, start Microsoft Windows Failover Cluster Manager and verify that it includes Oracle Fail Safe as a resource in the Cluster Group (the group containing the Microsoft Windows Failover Clusters resources critical to cluster operation).
To verify that Oracle Fail Safe is listed as a resource, use the Microsoft Windows Failover Clusters PowerShell interface as shown below:
PS C:\Users\john> Get-ClusterGroup "Cluster Group" | Get-ClusterResource
The query shows the following result:
Name State Group ResourceType ---- ----- ----- ------------ Cluster Disk 4 Online Cluster Group Physical Disk Cluster IP Address Online Cluster Group IP Address Cluster Name Online Cluster Group Network Name Oracle Fail Safe Server Online Cluster Group Generic Service
After installing Oracle Fail Safe on all cluster nodes and verifying the cluster, start the Microsoft Windows Failover Cluster Manager and verify that it includes the cluster resource types for Oracle Fail Safe.
To verify whether Oracle Database Oracle Resource is registered with Microsoft Windows Failover Clusters, use PowerShell interface as shown below:
PS C:\Users\john> Get-ClusterResourceType "Oracle Database"
Name DisplayName ---- ----------- Oracle Database Oracle Database
To verify whether Oracle TNS Listener Oracle Resource is registered with Microsoft Windows Failover Clusters, use PowerShell interface as shown below:
PS C:\Users\john> Get-ClusterResourceType "Oracle TNS Listener"
Name DisplayName ---- ----------- Oracle TNS Listener Oracle TNS Listener
