SUSE Linux 10 for SAP

PREPRATION OF LINUX FOR SAP INSTALLATION

According to sap note:

During Installation:

SUSE Linux Enterprise Server 10

+ SAP Application Server Base

+ X Window System

+ Print Server

+ C/C++ Compiler and Tools

+ Server Base System

+ "MD5" password encryption

+ 32Bit Runtime Environment

+ swap size should be 40GB

After Installation:

+ glibc-devel-32bit

+ ntp server

+ Activate sysstat (service sysstat)

Activate sysstat using command line

chkconfig sysstat on

/etc/init.d/sysstat start

+ saplocales 2.4-2.x86_64.rpm

+ After making changes to the

"glibc" (e.g. through an update) you must reinstall both, the "sap-locale"

and "saplocales" RPM packages

+ sapinit

+ AUTO_DETECT_UTF8="no" is set in: /etc/sysconfig/language

+ The sapinit script automatically sets the number of open file

descriptors for the groups sapsys, sdba and dba. So all

applications that run under the above groups will already have the

SAP recommended limits.

In this case you can edit the file

/etc/sysconfig/sapinit

and modify the limit for the group to which the application

belongs. E.g. if it belongs to sapsys you can put:

LIMIT_1="@sapsys soft nofile 48000" LIMIT_2="@sapsys hard

nofile 48000"

Afterwards you need to execute

/etc/init.d/boot.sapconf restart

and log off and log in again in order to make the changes take

effect

+ After having installed the Web Service Interface (which uses

"sapstartsrv" and "sapcontrol") the following configuration stepts

are required:

The sapstartsrv file within directory /etc/pam.d has to be created

and has to contain the following lines:

#%PAM-1.0

auth requisite pam_unix_auth.so nullok
