To license your product, register the appropriate license key with your DB2® database product.
If you want the license key added automatically during product installation, copy the license key to the /db2/license directory of the installation image before launching the DB2 Setup wizard.
For example, ensure you add the db2ese_c.lic or db2ese_u.lic license files to the /db2/license directory of the installation image before installing DB2 Enterprise Server Edition. If you do not add any license files to the /db2/license directory, you will see a "License not registered" message in the output from the db2licm -l command or in the License Center. You can apply the licenses manually after the installation by running the db2licm -a command.
If you register a valid license key, the db2licm -l command will successfully list all the products with available license information.
