This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Are you also going to install an SAP R/3 system with ABAP enviroment, MaxDB, application server and the R/3 frontend too? NetWeaver shines best together with SAP's own ERP system. According to my instructor, 5G will do for a personal edition. There's only 4.3G free in my laptop, so I gave up.
