When SLES for SAP is not SLES for SAP

Print Friendly and PDF

I recently downloaded and installed "SUSE Enterprise Linux for SAP 12 SP3" into a local virtual machine.
It seemed to contain everything that I thought it would contain with regards to included SAP Linux packages.

Noteable were the following in my local VM:

# which saptune
/usr/sbin/saptune
# rpm -qa | grep sap
cyrus-sasl-gssapi-32bit-2.1.26-7.1.x86_64
sap-netscape-link-0.1-1.2.noarch
sap-installation-wizard-3.1.81-3.1.x86_64
yast2-sap-scp-1.0.3-11.2.noarch
saptune-1.1.3-1.1.x86_64
saprouter-systemd-0.2-1.1.noarch
cyrus-sasl-gssapi-2.1.26-7.1.x86_64
patterns-sles-sap_server-12-77.8.x86_64
patterns-sles-sap_server-32bit-12-77.8.x86_64
yast2-saptune-1.2-1.5.noarch
sap-locale-32bit-1.0-92.4.x86_64
sapconf-4.1.8-1.18.noarch
sap-locale-1.0-92.4.x86_64
yast2-sap-scp-prodlist-1.0.2-4.2.noarch
# cat /etc/os-release
NAME="SLES"
VERSION="12-SP3"
VERSION_ID="12.3"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles_sap:12:sp3"
# uname -a
Linux hana01 4.4.73-7-default #1 SMP Fri Jul 21 13:26:40 UTC 2017 (6beeafd) x86_64 x86_64 x86_64 GNU/Linux


All looks good to me.

I then created an Azure hosted virtual machine using the image "SLES for SAP 12 SP3 (BYOS)":

 

The Azure VM seems to be missing a lot of the packages that I would expect to be in place:

# which saptune
which: no saptune in (/sbin:/usr/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/mit/bin)
# rpm -qa | grep sap
patterns-sles-sap_server-12-77.8.x86_64
yast2-sap-scp-prodlist-1.0.2-4.2.noarch
yast2-sap-scp-1.0.3-11.2.noarch
cyrus-sasl-gssapi-2.1.26-7.1.x86_64
sapconf-4.1.10-40.37.1.noarch
# cat /etc/os-release
NAME="SLES"
VERSION="12-SP3"
VERSION_ID="12.3"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles_sap:12:sp3"
# uname -a
Linux hana01 4.4.82-6.3-default #1 SMP Mon Aug 14 14:14:02 UTC 2017 (4c72484) x86_64 x86_64 x86_64 GNU/Linux


Notice also that the Kernel release is slightly newer on the Azure image, plus the version of the sapconf package is slightly newer.
The most important point is that the Azure image is missing the saptune package.
This is important as it is a method presented in numerous SAP notes for automatically applying the recommended O/S settings (that's right, they don't all get applied out-of-the-box).
