Why... Why... Why?
This blog is dedicated to documenting error resolution and other tidbits that I discover while working as a Consultant in the Oracle EPM (Hyperion) field. As much of my job revolves around issue resolution, I see an opportunity to supplement the typical troubleshooting avenues such as the Oracle Knowledgebase and Oracle Forums with more pinpointed information about specific errors as they are encountered.

Problem Accessing Windows Share on Node - BackConnectionHostNames

Windows 2008 R2 has some enhanced security which can get in the way of the Hyperion installation process. The problem is that the default settings will not allow network connections back to the node itself. For instance, if you create a windows share on a particular node, and then try to access the share from the same node, the connection fails. However, anywhere else on the network will be able to access the share.

This can come into play for the Windows Shares for FDM, Reporting and Analysis, and the Share for the LCM import_export assuming you are using the Hyperion servers to host the shares, rather than a remote share location. Additionally, you will notice that if you log into a server and try using the client tools to connect to Hyperion it will fail on one node, but work on the others. For instance, if you open FDM Workbench and try to connect to FDM it may show "Backup Load Balance Server is being used!". This is because the server cannot talk back to itself to connect to the primary load balance server.

The Solution:

Error message when you try to access a server locally by using its FQDN or its CNAME alias after you install Windows Server 2003 Service Pack 1: "Access denied" or "No network provider accepted the given network path"

Additional info:

Add the new key "BackConnectionHostNames" as a Multi-String Value in this registry path:

Enter the different names for the node using a newline as a separator:

  1. Thanks, this is useful to know! I nowadays recommend using DFS for making the file shares fault tolerant (the share can be replicated on two or more servers) so that might be why I haven't bumped into this issue yet...
