Unable to start the Database Server because the path to the socket file is too long

For help moving a projects_root, see Moving or creating additional projects_root directories.
Unable to start Klocwork Servers following Windows installation
If you see one of the following messages after installing the Klocwork Server package on Windows:
- Error 1920. Service Klocwork 22.4 Server (Klocwork 22.4 Server) failed to start. Verify that you have sufficient privileges to start system services.
- Service Klocwork 22.4 License Server failed to start. See installation log for more details.

Database connection error
Do not locate the projects_root directory on NFS to avoid issues with file locking.
If you see the following error:
Error occurred while connecting to database: Database connection to <database> refused: Communications link failure due to underlying exception
Check the host name in the error message. If the host name is not a fully qualified host name that includes the domain (for example, server1.klocwork.com), you need to set the fully qualified domain name for the Database Server.
To do this:
- Stop the Database Server:
kwservice --projects-root <projects_root> stop database
- Run the following command:
kwservice --projects-root <projects_root> set-service-property database host <fully-qualified-host-name>
- Start the Database Server:
kwservice --projects-root <projects_root> start database
