SAP HANA License Management

This Blog’s here to cover little bits of information that SAP HANA License Management.

About Managing SAP HANA Licenses

     License keys are required to use SAP HANA Database. We can install and delete the license keys using the SAP HANA Studio, SAP HANA HDBSQL command line tool and HANA SQL Query Editor.

HANA License Key Types

     The SAP HANA database supports two kinds of license key.

                    I. Temporary License Key

                    II. Permanent License Key

Temporary License Key:

            The temporary license keys are automatically installed with a new SAP HANA database installation. It is valid for 90 days from installation date. During this period we should request in service market place and apply permanent license key.

Permanent License Key:

The permanent license keys are valid until the predefined expiration date. It has to be requested on the SAP Service Marketplace under Keys & Requests and applied to the individual SAP HANA database. Furthermore they specify the amount of memory licensed to the target SAP HANA installation.

Note: Before a permanent license key expires, we should request and apply a new permanent license key. If it is expires, a temporary license key valid for 28 days is automatically installed. During this time, we can request and install a new permanent license key again.

There are two types of permanent license key available for SAP HANA

                    I.  Unenforced (SWPRODUCTNAME=SAP-HANA)

                    II. Enforced (SWPRODUCTNAME=SAP-HANA-ENF)

Unenforced License:

If an unenforced license key is installed, the operation of SAP HANA is not affected if its memory consumption exceeds the licensed amount of memory.

Enforced License:

If enforced license key is installed the system will be locked if memory consumption of HANA exceeds the license amount of memory plus some tolerance. If this happens HANA has to be restarted or a new license key should be requested, or a new license key that covers the amount of memory in use needs to be installed.

Authorization for Licensing Management

            The user required authorization of LICENSE ADMIN system privilege.

Important Points

There are a few different license models for SAP HANA depending on the business scenario (SAP HANA Stand-alone, SAP HANA Cloud, SAP Business Suite, SAP NetWeaver Business Warehouse or another Application on top of SAP HANA, etc.) and not all of them are based on memory.

If anyone have license related any questions, Please Contact with your SAP Account Executive who will gladly provide details.

Delete an Existing Permanent License Key

     We can delete all existing license keys in an SAP HANA database, for example, if permanent license keys with an incorrect installation number or incorrect system number were installed on the database.

Prerequisites

You have the system privilege LICENSE ADMIN.

Uninstall the license key using one of the following options:

SAP Hana Studio

     In the Systems view, right-click the system and choose Properties – License.

Choose Delete License Key.

Hana SQL Console

     Execute the SQL command UNSET SYSTEM LICENSE ALL

Hana HDBSQL

     Execute the SQL command UNSET SYSTEM LICENSE ALL

     All permanent license keys are deleted. This results in the lockdown of the database. The installation of a new, valid permanent license key is required to unlock the database.

System Lockdown

The system goes into lockdown mode in the following situations:

     1.     The temporary license key has expired.

     2.     You were using a temporary license key and the hardware key has changed.

     3.     The permanent license key has expired and you did not renew it within 28 days.

     4.     The installed license key is an enforced license key and the current memory consumption exceeds the licensed amount plus the tolerance.

     5.     You deleted all license keys installed in your database.

In lockdown mode, no queries are possible. Only a user with the system privilege LICENSE ADMIN can connect to the database and execute license-related queries, such as, obtain previous license data, install a new license key, and delete installed license keys. In addition, the database cannot be backed up in lockdown mode.
