SAP on Linux

I was at my Chennai office to conduct training and I called it as “SAP on Linux
I started by Thursday for two days training, to meet some of my counterparts and friends out there.

The class was packed with around 20 new joiners, who have just started to venture into SAP Basis. I started my session by keeping in mind: On the long run; if they have to make a choice between Windows and Linux/UNIX on SAP, there wouldn’t be a second thought to have the fun with Linux.

I picked up RedHat Linux for the demo session; since I had deployed FIVE SAP systems at my Bangalore office and they are running well on RedHat AS-4 and CentOS-5 [The number FIVE really matters for me]

I would like to paste the contents of some of the important slides:

Tail:
Closely an year back at the same workplace: My first CRM installation on “ ONE ” server out of 30 other running SAP servers.
I proposed to do it on Linux, but it didn’t happened since the senior was comfortable with Windows-2003. I said to myself “My call is not too far but FAR and the count started from FIVE
