When installing eHealth 6.3.2.x on a Windows 2008 R2 or Windows 2012 server the Oracle application installs successfully, but then it cannot create the database and the installation fails.


When reviewing the installation logs in %NH_HOME%/log/install, the CreateDb_v.log file contains the following error:

nhCreateDb FAILED: log file is FAR TOO SMALL (297 vs 15000+ lines)

The numbers in parenthesis may vary but the error is otherwise identical.


  1. Completely uninstall eHealth and Oracle, as per the instructions in the Appendix of the eHealth Installation Guide.
  2. Remove any Powershell path entries in the PATH environment variable.
  3. Install the root certificate UTN-USERFirst-Object.p7b on the server. The certificate and installation instructions are provided in the attachments at the end of this document.
  4. Reboot the server, then start the fresh installation again.


The root certificate is a third party object not created by CA Technologies that we provide here for your convenience. It resolves a problem found with MKS Nutcracker on Windows servers. Encountering this problem usually indicates the the Windows operating system missed one or more security updates in the past.
