Introducing SAP NetWeaver BW powered by SAP HANA
In this section of the book, we will see how SAP HANA acts as a database for SAP BW.
Getting ready
With SAP HANA being an in-memory database, it works in a similar way to other traditional databases with regards to administration, and from a technical point of view.
How to do it…
SAP HANA acts as a database in the case of BW on HANA. There are three options to deploy SAP BW on HANA:
- Fresh installation of BW on HANA: In this option, we create a new BW instance and connect to the SAP HANA database. This is the easiest option of the three.
- Upgrade the existing BW system: In this option, we first upgrade the existing BW system to a minimum 7.3 SPS5. Then we change the underlying traditional disk-based relational database to the new in-memory database, the SAP HANA system.
- System copy with BW on HANA: In this method, we copy the running production BW system to a new system while keeping the production system running on existing traditional databases...
