Manual changes after installation

1. Changing the machine name after installation

If a full SSL certificate is not used, the machine name should be avoided from being changed under any circumstances once the Vienna Test System has been installed. The supplied self-signed SSL certificate is linked to the original machine name. If the machine name is changed, communication between the VTS components will no longer be correctly configured.

If this does happen, the following steps should be taken:

1. Uninstall the Vienna Test System (the database will not be deleted)

2. Make sure that the certificate “SchuhfriedSelfSignedCertificate” is deleted:

   1. Open the Certificate Management, run certlm.msc on the local computer.

   2. Go to Personal → Certificates.

   3. Right-click on SchuhfriedSelfSignedCertificate and select Delete.

3. Reinstall the Vienna Test System (the existing database will be recognized and used).

4. Make adjustments to the VTS database using an SQL script to apply the new computer names:

   1. Run the SQL script: update_identityserverconfiguration.sql. The script is located in the installation files in the Scripts\Help folder.

   2. It is important that the same version of the Vienna Test System is used when uninstalling and reinstalling the software.

2. Change the Bit.ly configuration

The VTS uses the external tool “Bitly” to send invitation links via email to the test takers. The following changes can be made to the configuration:

1. IsBitlyEnabled

This key can be used to enable or disable the Bitly service. Valid values are ‘true’ and “false.” Here is an example:

<add key="IsBitlyEnabled" value="false"></add>

 2. BitlyAccessToken

This key can be used to overwrite the system's default token. For example, you can use your own Bitly account. Here is an example:

<add key="BitlyAccessToken" value="123456789abcdefghijk"></add>
