Applying the Hotfix to TDV Server, Studio, and Business Directory
Hot fixes include bug fixes to any TDV major, minor or service pack version.
The latest hotfix, must be applied to the same TDV major, minor and service pack level. For example,
hotfix TDV 8.3.0.005 can only be applied to TDV 8.3.0
hotfix TDV 8.3.1.002 can only be applied to TDV 8.3.1
The latest hotfix, requires a clean update of your TDV Server and Business Directory environment. The optimal way to achieve the clean environment is to apply the hotfix as if it was a Service Pack.
To apply a hotfix
1. Optionally, perform a full TDV and Business Directory backup. For details about backup export, see the TDV Administration Guide or the Business Directory Guide.
2. If installing on Windows, be sure to use Run as Administrator.
3. For Windows, make sure to close any open windows to the repository/jdk folder.
4. Stop the TDV Server.
5. Copy the hotfix zip file to <TDV_install_dir>.
6. Unzip the file.
