hi,

You have to follow the suggestion given by our gurus and while installing linux create all the directories required by sap. You may have to use VG for creating extended partitions as linux supports only limited partitions.

Main problem with come with java and xlib dependencies for the installation.

Dear Ahamed,

you should at least follow the following:

  • Read installation guide SAP on Unix which are availabe via [SAP Service Marketplace - Instguides|https://service.sap.com/instguides]

  • Read important notes, e.g. [171356|https://service.sap.com/sap/support/notes/171356], [1048303|https://service.sap.com/sap/support/notes/1048303] and their references

  • Check if you have supported hardware for Linux via [SAP on Linux Homepage|] -> Supported Platforms -> Hardware

Hi,

you can either let sapinst create them, or you can create them yourself.

I strongly recommend, that you perform some test installations yourself before you are going to install your productive system. During this process you'll get familiar with the handling and all the necessary steps. If you don't have time for such a self education (no offense meant), you should get professional support (either SAP consulting or 3rd party SAP consulting companies).

Thanks,

Hi,

Following are the steps for ECC6 setup in RHEL5 (64Bit)

Red Hat Enterprise Linux 5: Installation

When asked about the desired timezone, choose "System clock uses

UTC" in order to automatically switch between normal and daylight

savings time.

When offered to customize the software selection, choose

"Customize now".

keep the packages selected by default and add packages

eventually listed with the group:

- Development/Development Libraries (for Oracle databases)

- Development/Development Tools (for Oracle databases)

- Servers/Printing Support

- Base System/Base

- Base System/Legacy Software Support (add the compat-openldap

package)

- Base System/X Window System

The following packages can't be chosen during installation and have

to be installed afterwards:

- libXp

- libunwind (on ia64)

Hostname

Both commands "hostname" and "hostname -s" must return the

hostname without domain, "hostname -f" must return the fully qualified

hostname and domain.

HOSTNAME is set to the short name without domain in /etc/sysconfig/network and set up /etc/hosts so

that it is configured like this

127.0.0.1 localhost.localdomain localhost

192.168.0.1 sap.ggn.com sap

Updating the Glibc package

We may use any glibc package for your OS version provided by Red Hat.

After updating the glibc package we need to (re-) install the saplocales

package:

rpm -Uvh --force <saplocales.rpm>

Linux kernel parameters

To do this append the following lines to /etc/sysctl.conf

kernel.msgmni=1024

kernel.sem=1250 256000 100 1024

vm.max_map_count=300000

Activate these settings with the command "sysctl -p".

Process resource limits

Some components (e.g. the SAP J2EE engine, Oracle RDBMS software, ...) need to keep a large number of file handles opened simultaneously. You need to increase the limit of files one process can open at a time by extending /etc/security/limits.conf with lines similar to these:

@sapsys hard nofile 32800

@sapsys soft nofile 32800

@dba hard nofile 32800

@dba soft nofile 32800
