SAP Basis Howto Blog about SAP ERP especially on technical field such as SAP Basis/NetWeaver concepts, monitoring, administration, performance tuning, SAP Implementations, ABAP, Data Migration, OS, Database server, and FAQsFriday, June 10, 2011Installing SAP R/3 Application server on Linux In this article, I will give you step by step for installation of application server system SAP R / 3 using the Linux OS.Why use Linux?Instead better use Windows?There are some things that a consideration to me why using Linux include:

1. Database Instance that will be used is Oracle with a platform AIX (IBM's proprietary UNIX).Between AIX and Linux, UNIX machines are equally so compatibility will be more awake than using Windows.2. Linux is free and open source.By nature, I was much easier to perform tuning and search for references on the Internet.3. Communication between Linux and AIX will use NFS, while Windows and AIX will use SAMBA.4. Linux machine is more stable, reliable, and most importantly the virus-immune.5. Linux is also less expensive in terms of maintenance, hardware requirements, compared to using Windows (must have a license) and AIX (in terms of licensing and hardware).Selection of Linux distributions that will be used freely.I prefer the distro that can use the concept of LVM (Logical Volume Management) so I can make a logical volume space maintenance easier.I will try to explain using Redhat machine.I personally have tried to use SuSE as well.The main difference between them is the problem of the default file system used.Redhat uses ext3, while SuSE using reiserfs.

Excellence ext3 and reiserfs is the ability to manage the logical volume size online.So we can easily increase the size of logical volumes without having to unmount the logical volume.We start, yes ...

1.OS InstallationWhen the OS installation, prepare a sufficient partition for the installation of SAP.The table on the following attachment (Disk) The following will give an explanation setting partitions using LVM.

2.Installing the Central InstanceSince we will use an existing Database Instance on AIX 64 bit machine, then we have to install the Central Instance.Installing the Central Instance package in Linux is to get the executable files from the SAP kernel for Linux.Set environment needed to run sapinst among others:LD_LIBRARY_PATH = / sapmnt / [SID] / exeSAPINST_JRE_HOME = / opt / [location of java runtime environment]DISPLAY = [IP_Address of Windows Client]: 0.0umask = 22

To test, run the xclock command on the console.If an analog clock image, it means that environment is set correctly.If not appear, review the value of each environment variable you.

Go tothedirectorysapinst.SapinstRuncommandonthe console.

Choose Install Central Instance.
