FAQ : How to de-installed License keys in SAP HANA ?

License keys can be de-installed using the following SQL statement:

UNSET SYSTEM LICENSE ALL

This command will delete all existing license keys installed so far in the database instance. Furthermore, it sets the system immediately to lockdown state. A new valid permanent license key needs to be installed in order to unlock the instance. Like installing a license key, your user needs the LICENSE ADMIN system privilege to delete the license keys.
