These are rough notes, do not look at te typos
In short: SAP on 64bit XenoLinux
Purpose: Primarilly for sandboxes and training systems.
Fact: Lots of SAP installations are on Windows because of the cost-factor. But lots of large enterprises often use UNIX* and Oracle for thier SAP systems and have high licence and hosting costs. Even if enterprises are using Windows they tend to use a higher cost windows server version with a high-end SQL-server database.
Costs:
UNIX*/hardware alternatives:
Result: AMD64 or Intel Xeon, XEN, MaxDB Alternative (support needs to be investigated): x86, OpenSolaris, containerization/zones, MaxDB
Distribution:
Platforms described by SAP:
Note: Best supported platform for Linux is x86_64 64bit using SUSE or RED HAT.
References:
SAP statements:
Kernel related support: Therefore the following can't be supported:
If you already are an SAP customer, you can also have a look at SAP note 784391 (login required) for further, more detailed, information.
Make sure that you have installed the required SDK: You have to download the special "JDK 1.4.2 for SAP Customers". Please refer to the new SAP Note 1090932.
Performance should be *really* bad :(
Install notes:
Create disks:
qemu-img create -f raw ../qemu/CentOS64bit/centos.img 2000M qemu-img create -f raw ../qemu/CentOS64bit/centos2.img 2000M qemu-img create -f raw ../qemu/CentOS64bit/centos3.img 2000M (not used for OS install)
Note: We use a USB disk with FAT32 so no disks larger then 2048MiB. For larger filesystems then 2GiB we will use LVM in Linux. But we can only have 4 disks by default, unless you show then as USB dev.
Start installation:
E:\_OSimages\qemu-bin-windows>qemu-system-x86_64.exe -L . -m 512 -boot d -cdrom ../iso/Cen tOS-5.1-x86_64-bin-1of7.iso -hda ../qemu/CentOS64bit/centos.img -hdb ../qemu/CentOS64bit/c entos2.img
Note: Most Linux distributions install SMP kernels by default, so we can switch to -smp 2 later in the process.
Howto switch iso image in Qemu:
ctrl-alt-2 eject cdrom change cdrom ../iso/CentOS-5.1-x86_64-bin-2of7.iso ctrl-alt-1
SAP has made a 32bit version available for vmware player which is only suitable for trial and preview. In theory they still support Netweaver on 32bit Linux but 64bit is recomended.

Apply for an evaluation license key
As soon as you have installed the application server software your hardware key
is reported on the command line. Please follow this link and fill out the form
there using that key and a 90-day license should be emailed to you within
minutes. This license can be renewed 7 days before expiry, just apply again by
using the same form. The license has to be installed via transaction "slicense"
in the ABAP-stack of the system. Therefore upload the license file, which is
attached to the mail, to your Linux system, where it can be accessed by the
SAP-system. Logon as user SAP* and run "slicense" in the GUI. Follow the button
"New Licenses" at the top of the window and press "Install". A file dialog
should open where you can navigate to and select the license file.
