Installing License using the Command Line (CLI)

If you have the repl subdirectory of your Datical installation on your path, you can run these hammer commands from any directory. 

...

Or if you don't have it in your path, then you need to be in your "<Datical Installation>/repl" directory to run these commands from the command line:

Just before installing your new license, you can run an uninstall command to uninstall all older licenses:

hammer uninstallLicense

The uninstall command will uninstall all of your Liquibase Enterprise/Datical DB licenses.

Then copy the new license file to the location where you keep your license files.  

Run the following command to install your new license:

hammer installLicense <path_to_license_file>

For example:

hammer installLicense /opt/datical/license/<CompanyName>-<ExpirationDate>.lic

To check what license is currently installed run the following command:

hammer show license
