Important: Installation of Oracle databases not possible

The SAP Installation Wizard does not allow installing products together with Oracle databases. To install an Oracle database, install the base product SUSE Linux Enterprise Server first, then install the Oracle database and later convert your installation to SLES for SAP. This is necessary because the Oracle databases installer queries for the existence of certain files, not all of which are included in a SLES for SAP installation.

For more information about converting, see Section 3.4, “Converting a SLES installation to a SLES for SAP installation”.

4.2 First steps #

These first steps are only relevant during the installation workflow.

When the system is booted, it displays the screen Welcome. Proceed with Next.
The screen Network Settings will now open. This gives you an opportunity to change the network settings.
When you are finished configuring networking, proceed with Next.
Important: Configure networking as recommended by SAP
Make sure to configure the network connection according to the documentation of your SAP application.
For information about configuring networking, see Administration Guide, Chapter “Basic Networking”, Section “Configuring a Network Connection with YaST” (https://documentation.suse.com/sles-15).
(While the next screen loads, the Welcome screen may appear again for a few seconds.)
Choose one of the following options:
Create SAP file systems and start SAP product installation
Allows installing an SAP application and setting up the system as a server providing SAP installation routines to other systems.
Continue with Section 4.3, “Using the SAP Installation Wizard”.
Only create SAP HANA file systems, do not install SAP products now
Create an SAP HANA file system on SAP BusinessOne-certified hardware.
Important: Hardware requirements
Make sure your machine fulfills the hardware requirements for SAP HANA detailed in Section 2.1, “Hardware requirements”. Otherwise, this option will not create a new file system and the installation workflow ends at this point.
Finish wizard and proceed to OS login
Do not install an SAP application and continue to the login screen of SUSE Linux Enterprise Server for SAP Applications.
Proceed with Next.

4.3 Using the SAP Installation Wizard #

Use the SAP Installation Wizard to install an SAP NetWeaver system (including database) or an SAP HANA system.

To install other SAP applications or to create a more advanced SAP HANA setup, directly use one of the installation methods provided by SAP instead of this wizard.

Tip: Installing an SAP application in a fully installed system

This process is documented as it appears during the installation workflow. However, it also applies to the YaST module SAP Installation Wizard which is available in the installed system.

To start the SAP Installer, from the desktop, choose Applications › System › YaST, continue in the YaST control center by choosing Miscellaneous › SAP Installation Wizard.

Tip: SAP Installation Wizard configuration

The SAP Installation Wizard configuration is specified and documented in /etc/sysconfig/sap-installation-wizard. You can change it according to your needs.

In the screen SAP Installation Wizard, provide the Location of the SAP Installation Master (Figure 4.1, “Location of SAP installation master”). The location can either be a local, removable, or remote installation source.

Figure 4.1: Location of SAP installation master #

Select the appropriate option from the drop-down list. In the text box, specify the path to your source according to the format given in the following table.

Table 4.1: Media source path #

Option	Description	Format of Path
Local Sources
dir://	a local directory	`/path/to/dir/`
Removable Sources
device://	a locally connected hard disk	`devicename/path/to/dir/on/device`
usb://	a USB mass storage device	`/path/to/dir/on/USB`
cdrom://	a CD or DVD	`//`
Remote Sources
nfs://	an NFS share	`server_name/path/to/dir/on/device`
smb://	an SMB share	`[user_name:password@]server_name//path/to/dir/on/server[?workgroup=workgroup_name]`

Tip: Remote location specification

To install from an NFS source, specify the name of the server and the complete path to the media data. For information about setting up a remote installation server, see Chapter 6, Setting up an installation server for SAP media sets.

If you have installed an SAP application from an installation server before or set up your system to be an installation server, you can also directly choose that server as the provider of the Installation Master. To do so, use the drop-down list below Choose an installation master.

Under Advanced Options, choose from the following options:
Collect installation profiles for SAP products but do not execute installation
Use this option to set the installation parameters, but not perform the actual installation. With this option, the SAP Installer (SAPinst) will stop without performing the actual SAP product installation. However, the steps that follow fully apply.
For more information, see Section 4.4, “Continuing an installation using an installation profile”.
Serve all installation media (including master) to local network via NFS
Set up this system as an installation server for other SUSE Linux Enterprise Server for SAP Applications systems. The media copied to this installation server will be offered through NFS and can be discovered via Service Location Protocol (SLP).
Proceed with Next.
The SAP Installation Wizard will now copy the Installation Master to your local disk. Depending on the type of Installation Master you selected, the installation will continue differently:
- If you are installing an SAP HANA database, skip ahead to Step 8.
- If you are installing an SAP NetWeaver application, continue with the next step.
On the screen SAP Installation Wizard, provide the location of additional Installation Media you want to install. This can include an SAP kernel, a database and database exports.
Copy a medium
Specify a path to additional Installation Media. For more information about specifying the path, see Table 4.1, “Media source path”.
Skip copying of medium
Do not copy additional Installation Media. Choose this option if you do not need additional Installation Media or to install additional Installation Media directly from their source, for example, CDs/DVDs or flash disks.
When choosing this option despite your SAP product requiring additional Installation Media, you will later need to provide the SAP Installer (SAPinst) with the relevant paths.
Proceed with Next.
If you chose to copy Installation Media, the SAP Installation Wizard will copy the relevant files to your local hard disk.
Figure 4.2: SAP Installation Wizard: additional Installation Media #
After copying the Installation Media, you will be asked whether you want to prepare additional Installation Media. To do so, click Yes. Then follow the instructions in Step 3.
Otherwise, click No.
In the screen What Would You Like to Install, under The SAP product is, choose how you want to install the product:
SAP standard system
Install an SAP application including its database.
SAP standalone engines
Engines that add functionality to a standard product: SAP TREX, SAP Gateway and Web Dispatcher.
Distributed system
An SAP application that is separated onto multiple servers.
SAP high-availability system
Installation of SAP NetWeaver in a high-availability setup.
System rename
Allows changing the various system properties such as the SAP system ID, database ID, instance number or host name. This can be used to install the same product in a very similar configuration on different systems.
Figure 4.3: SAP Installation Wizard: installation type and database #
If you selected SAP Standard System, Distributed System or SAP High-Availability System, additionally choose a back-end database under Back-end Databases.
Proceed with Next.
You will now see the screen Choose a Product. The products shown depend on the Media Set and Installation Master you received from SAP. From the list, select the product you want to install.
Proceed with Next.
Figure 4.4: SAP Installation Wizard: choose a product #
You will be asked whether to copy Supplementary Media or Third-Party Media. To do so, click Yes and then follow the instructions in Step 3.
Otherwise, click No.
Note: Difference between Supplementary Media/Third-Party Media and additional software repositories
Both types of delivery mechanisms allow installing software that is neither part of the SUSE Linux Enterprise Server for SAP Applications media nor part of your Media Set from SAP. However, the delivery mechanism is different:
- Supplementary Media/Third-Party Media is installed using an AutoYaST file which allows creating an installation wizard and custom installation scripts.
- Additional software repositories are RPM package repositories that you will remain subscribed to. This means you receive updates for Third-Party Media along with your regular system updates.
For information on creating Supplementary Media, see Appendix C, Supplementary Media.
On the screen Additional software repositories for your SAP installation, you can add further software repositories. For example, for add-ons that are packaged as RPM. To do so, click Add new software repositories. For more information about adding repositories, see Deployment Guide, Chapter “Installing and Removing Software”, Section “Adding Software Repositories” (https://documentation.suse.com/sles-15).
Proceed with Next.
Note: Location of copied SAP media
At this point, all data required for the SAP installation has been copied to /data/SAP_CDs (unless you chose to skip the process of copying). Each Installation Medium is copied to a separate directory. You might find the following directory structure, for example:
```
> ls /data/SAP_CDs
742-KERNEL-SAP-Kernel-742
742-UKERNEL-SAP-Unicode-Kernel-742
RDBMS-MAX-DB-LINUX_X86_64
SAP-NetWeaver-740-SR2-Installation-Export-CD-1-3
SAP-NetWeaver-740-SR2-Installation-Export-CD-2-3
SAP-NetWeaver-740-SR2-Installation-Export-CD-3-3
```
/data/SAP_CDs is the default directory as specified in the /etc/sysconfig/sap-installation-wizard configuration file.
Depending on the product you are installing, one or more dialogs will prompt you to supply values for several configuration parameters for the SAP application you are installing.
Supply the values as described in the documentation provided to you by SAP. Help for the configuration parameters is also available on the left side of the dialog. For more information, see Section 2.6, “Required data for installing”.
Fill out the form (or forms), then proceed with OK.
Figure 4.5: Product parameters #

When you are done, the SAP Installation Wizard will download additional software packages.
You will be asked whether to continue the installation or prepare another SAP product for installation. If you choose to prepare another SAP product, start from the beginning of this procedure.
(Optional) When installing SAP HANA on a system that is not certified for SAP HANA and does not meet the minimum hardware requirements for SAP HANA TDI (Tailored Datacenter Integration), you will be asked whether to continue. If you receive this message unexpectedly, check Section 2.1, “Hardware requirements” and the sizing guidelines from SAP at https://service.sap.com/sizing (you need your SAP ID to access the information).
Otherwise, continue with Yes.
The following steps differ depending on the type of SAP application you are installing:
- When installing an SAP HANA database, SAP HANA will now be installed without further question.
- When installing an SAP NetWeaver application, the actual installation will be performed using the SAP Installer (SAPinst). After a few seconds, SAP Installer will open automatically.
  Follow the SAP Installer as described in the documentation provided by SAP. Most configuration parameters are correctly filled already.
Figure 4.6: SAP Installer: defining parameters #

Tip: Installation log files
If the installation of the SAP application fails, refer to the installation log files. They are located in /var/adm/autoinstall. Failed installations are recorded in files with names ending in .err.
For more information about log files, see Chapter 14, Important log files.
The final screen is Installation Completed.
To create an AutoYaST file for this installation, activate Clone This System for AutoYaST. The AutoYaST file will be placed in /root/autoinst.xml.
Click Finish.

4.4 Continuing an installation using an installation profile #

If you chose Collect installation profiles but do not execute installation during the previous run of the SAP Installation Wizard, this section will show you how to continue the installation of the selected SAP applications.

When collecting an installation profile, the SAP Installation Wizard copies product images to /data/SAP_CDs. It also prepares an installation environment for every product under the path /data/SAP_INST:

/data/SAP_INST/0/Instmaster
/data/SAP_INST/1/Instmaster
/data/SAP_INST/2/Instmaster
[...]

These files are re-used in the following. To continue the installation, follow these steps:

In /etc/sysconfig/sap-installation-wizard, set the following:
```
SAP_AUTO_INSTALL="yes"
```
In the case of an SAP HANA/SAP BusinessOne installation, the SAP Installation Wizard will later use the parameters documented in the AutoYaST files in /data/SAP_INST/number.
If you need to change any parameters, make sure to adapt the AutoYaST files at this point.
Open the YaST control center and start SAP Installation Wizard.
You will be asked whether to continue the pending installation. Select Install.
All further interactions happen within the SAP Installer. Follow the steps of SAP Installer as described in the documentation provided to you by SAP.
- In the case of an SAP NetWeaver installation, all parameters of the SAP Installer will be offered again for fine-tuning.
- In the case of an SAP HANA/SAP BusinessOne installation, the installer will not be offer to make any changes to parameters.

4.5 Partitioning for an SAP application without the SAP Installation Wizard #

If you do not want to use the SAP Installation Wizard, you can also create the partitioning for SAP applications directly from the command line. First, find the correct partitioning file in the directory /usr/share/YaST2/data/y2sap/ or create your own partitioning file. For more information, see Section 2.7.2, “Partitioning for the SAP system (stage 2)”.

When you have determined the correct partitioning XML file, run:

# yast2 sap_create_storage_ng ABSOLUTE_PATH_TO_PARTITIONING_FILE

4.6 Automated installation of SAP applications with AutoYaST #

The SAP Installation Wizard can be used from AutoYaST to automate the installation of SAP Applications.

4.6.1 SAP HANA installation #

The following AutoYaST snippet shows how an SAP HANA or SAP TREX installation can be automated:

<sap-inst>
  <products config:type="list">
    <product>
      <media config:type="list">
        <medium>
          <url>nfs://server/path1</url>
          <type>sap</type>
        </medium>
        <medium>
          <url>nfs://server/path3</url>
          <type>supplement</type>
        </medium>
      </media>
      <sapMasterPW>PASSWORD</sapMasterPW>
      <sid>SID</sid>
      <sapInstNr>INSTANCE_NUMBER</sapInstNr>
    </product>
  </products>
</sap-inst>

The sapVirtHostname element must be specified for distributed or highly available installations.

For a full SAP HANA example, including partitioning, see /usr/share/doc/packages/sap-installation-wizard/hana-autoyast.xml.

4.6.2 SAP NetWeaver installation #

For SAP NetWeaver, the following example shows how the installation can be automated. Specifically, this example is tailored to installing ASCS Instance of an SAP NetWeaver 7.5 ABAP Server distributed system with MaxDB (product ID NW_ABAP_ASCS:NW750.ADA.ABAP). When installing other products based on SAP NetWeaver, not all of the following variables may be necessary or these variables might need to be replaced by others:

The master password for the SAP NetWeaver instance: MASTER_PASSWORD
The SAP Identifier (SID): SID
The SAP kernel: KERNEL
The SAP instance number: INSTANCE_NUMBER
The ASCS virtual host name: ASCS_VIRTUAL_HOSTNAME
The SCS virtual host name: SCS_VIRTUAL_HOSTNAME
