How to install HANA license by OS commands

Symptom

You need to use OS commands to access the HANA Database and manage the license.

Because there's no HANA Studio or HANA Cockpit available to manage the license for some reason.

Environment

    HANA Platform 1.0
    HANA Platform 2.0

Resolution

1. Logon as sidadm user, connect to the Database via hdbsql.

    If it is a single container system, please try below command:

> hdbsql -n :315 -i -u -p

    If it is a MDC system, please try connecting to the system DB by below command:

> hdbsql -n :313 -i -u -p

2. Enable multiline mode in hdbsql

hdbsql => \mu

3. You need a new license key, which you can download from Support Portal.

4. Enter statement  SET SYSTEM LICENSE ''.

Please note to add quotation mark outside the content of the license file you just downloaded.

5. Execute the statement by command: \g

hdbsql => \g

Remarks:
Install the new license via hdbsql cannot replace the old license. Please consider to delete the old license key before installing the new one.

You can also delete license keys by executing the SQL statement UNSET SYSTEM LICENSE ALL.
