sap-hana-cloud-trial

Management script for experimenting with SAP HANA Cloud DB Trial using Eclipse via Tunnels with the goal of using the Eclipse-based modelling tools for cloud based HANA DBs.

Overview

SAP offers trial versions of their cloud based HANA DB which will automatically stop running after 12 Hours and are deleted after a week, but they come free of charge and are therefore very useful for experiments or in teaching settings.

Configuration

Prerequesits

• Eclipse 2018-12 R from https://www.eclipse.org/downloads/packages/release/2018-12/r
• Modelling tools for Eclipse from https://tools.hana.ondemand.com/2018-12/
• /tools directory from the SAP Cloud Platform Neo Environment SDK Version Java Web Tomcat 8 from https://tools.hana.ondemand.com/#cloud containing the neo command line tool
