You will learn to configure a server with an installed SAP environment and write your first program. It will export a listing of existing system users in tabular format.

To create an SAP program in Yandex Cloud:

  1. Prepare your cloud.
  2. Create a VM for SAP.
  3. Set up the VM file system.
  4. Set up an install configuration.
  5. Install SAP.
  6. Configure SAP.
  7. Check that the program runs as expected.

If you no longer need the resources you created, delete them.

Getting started

Sign up for Yandex Cloud and create a billing account:

  1. Go to the management console and log in to Yandex Cloud or create an account if you do not have one yet.
  2. On the Yandex Cloud Billing page, make sure you have a billing account linked and it has the ACTIVE or TRIAL_ACTIVE status. If you do not have a billing account, create one.

If you have an active billing account, you can go to the cloud page to create or select a folder for your infrastructure to operate in.

The cost of an SAP installation includes:

Create a VM for SAP

Create a VM with a public IP address:

  1. On the folder page in the management console, click Create resource and select Virtual machine.
  2. In the Name field, enter the VM name: vhcalnplci. This host name is used in the install script.
  3. Select an availability zone ru-central1-a.
  4. Under Image/boot disk selection, click the Cloud Marketplace tab and then Show more. In the window that opens, select the SLES for SAP 15 SP2 image.
  5. Under Disks select SSD as your boot disk type and specify 40 GB of disk size.
  6. Click Add disk to add another disk.
    1. Enter a name for the disk.
    2. Select HDD as type.
    3. Specify a size of 90 GB.
    4. Click Add.
  7. Under Computing resources:
    • Select the platform: Intel Ice Lake.
    • Specify the number of vCPUs and the amount of RAM:
      • vCPU: 2.
      • Guaranteed vCPU share: 100%
      • RAM: 8 GB.
  8. Under Network settings:

    • Enter a subnet ID or select a cloud network from the list.

      If you don't have a network, click Create network to create one:

      • In the window that opens, enter the network name and specify the folder to host the network.
      • You can select Create subnets to create subnets automatically.
      • Click Create.

      Each network must have at least one subnet. If there is no subnet, create one by selecting Add subnet.

    • In the Public IP field, select the Auto method for assigning an IP address.

  9. Under Access, specify the information required to access the instance:
    • Enter the username in the Login field.
    • In the SSH key field, enter the public part of your SSH key. You can create an SSH key pair to connect to the VM by following this guide.
  10. Click Create VM.

Set up the VM file system

Set up the created VM's file structure for the SAP install.

  1. Use SSH to connect to the created VM via PuTTY.

  2. Switch to root to get superuser privileges:

    sudo su

  3. Review a list of all the disks:

    lsblk

    Result:

    vda    254:0    0  40G  0 disk
├─vda1 254:1    0   4M  0 part
└─vda2 254:2    0  40G  0 part /
vdb    254:16   0  90G  0 disk

    Where:

    • vda: Boot disk.
    • vdb: Data disk.

  4. Create two partitions on the data disk (vdb): 20 GB for the distribution and 70 GB for SAP.

    1. To manage hard drive partitions, run the fdisk utility:

      fdisk /dev/vdb

      If launching fdisk returns the command not found error, add fdisk to Path:

      PATH=/sbin:$PATH

    2. To add your first partition, press n followed by Enter.

    3. To select primary, which is the default type, press Enter.

    4. To select default number 1, press Enter.

    5. To select first default sector 2048, press Enter.

    6. Specify size as +20G and press Enter.

    7. Repeat these steps to add another partition. Do not specify partition size in the last step. It will use the remaining 70 GB of disk space by default.

    8. To save the partitions you created, press w followed by Enter.

      Result:

      Welcome to fdisk (util-linux 2.33.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

    9. Check the disk structure:

      lsblk

      Result:

      NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda    254:0    0  40G  0 disk
├─vda1 254:1    0   4M  0 part
└─vda2 254:2    0  40G  0 part /
vdb    254:16   0  90G  0 disk
├─vdb1 254:17   0  20G  0 part
└─vdb2 254:18   0  70G  0 part

  5. Configure your vdb1 and vdb2 partitions with the ext4 file system:

    mkfs.ext4 /dev/vdb1
mkfs.ext4 /dev/vdb2

    Result:

    mke2fs 1.43.8 (1-Jan-2018)

  6. Create directories for the distribution and the SAP application server. Mount these to partitions vdb1 and vdb2:

    mkdir /usr/sap
mkdir /distr
mount /dev/vdb1 /distr
mount /dev/vdb2 /usr/sap

  7. For automatic remounting after reboot, edit /etc/fstab:

    vi /etc/fstab

    Make it look like this:

    LABEL=ROOT  /  xfs  defaults  0  1
/dev/vdb1 /distr ext4 defaults 1 1
/dev/vdb2 /usr/sap ext4 defaults 1 1

Configure install

Add the SAP installation files to your VM and configure the upcoming installation.

  1. Download the 11 archives with the SAP NetWeaver AS ABAP Developer Edition 7.52 SP04 installation files and unpack their contents to a local folder.

  2. Save the current VM connection session in PuTTY. You can use any name.

  3. Install and run WinSCP.

  4. Import the saved PuTTY session settings into WinSCP.

    1. In the Login window, click Tools.
    2. Select Import Sites.
    3. In the Import from field, select PuTTY and highlight the previously saved session.

  5. Connect to the VM via WinSCP.

    1. Select the session imported from PuTTY.
    2. Click Login.
    3. Enter the VM username.

  6. Import the SAP installation files that you unpacked from the previously downloaded archives into the /distr folder on the VM.

    1. In the left-hand window, open the folder with the unpacked SAP files.
    2. Highlight the files and click Upload.
    3. Set /distr/*.* as the import location on the VM.

    To be able to import the files, you have to be the owner of the /distr folder. The other option is to connect via WinSCP as a user with root access or configure the use of sudo when logging onto the system.

  7. On the VM, install and run UUIDD. This is the UUIDD (universally unique identifiers) daemon. It is required for SAP to run:

    zypper install uuidd
service uuidd start

  8. Check for the libaio and libaio1 libraries:

    rpm -qa | grep libaio
rpm -qa | grep libaio1

    The response will display the library versions built into the distribution.

  9. Find out the VM's private IP:

    ip addr show

    Result:

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
  link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
  inet 127.0.0.1/8 scope host lo
  valid_lft forever preferred_lft forever
  inet6 ::1/128 scope host
  valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
  link/ether d0:0d:11:31:ee:a6 brd ff:ff:ff:ff:ff:ff
  inet 10.0.0.29/24 brd 10.0.0.255 scope global eth0
  valid_lft forever preferred_lft forever
  inet6 fe80::d20d:11ff:fe31:eea6/64 scope link
  valid_lft forever preferred_lft forever

  10. Add the private IP to /etc/hosts.

    1. Open the file:

      vi /etc/hosts

    2. Add a line to it as below:

      <inet> vhcalnplci vhcalnplci.ru-central1.internal.

      Use an inet value from the eth0 block.

      Result:

      127.0.0.1 localhost
10.0.0.29 vhcalnplci vhcalnplci.ru-central1.internal

  11. Check the host name:

    hostname

    Result:

    vhcalnplci

Install SAP

  1. Modify the permissions to the folder containing the SAP install files.

    chmod -R 777 /distr

  2. Change to /distr:

    cd /distr

  3. Run the SAP install script:

    ./install.sh

  4. Accept the terms of the license agreement.

  5. Set a master password for the users to be created during the SAP install.

    Password requirements:

    • At least 7 English characters.
    • Contains capital letters and numbers.
    • No special characters.

  6. Wait for the installation to complete.

    The install may produce the following error message:

    Abort execution because of Step returns modlib.jslib.caughtException
Error: sapinst has finished with an error code, please find logs in /tmp/sapinst_instdir
Error code: 20

    The error is related to an expired license. To resolve:

    1. Download SAP ABAP AS Part License for SAP NetWeaver AS ABAP Developer Edition 7.52 SP04 from the official website.
    2. Unpack and copy it to the server/TAR/x86_64/ directory on the VM. You can do this using WinSCP.
    3. Run ./install.sh again to install SAP.

Run and configure SAP

  1. Install the SAP Logon front-end client on your computer.

  2. Run SAP Logon and configure a connection to the VM:

    • Application Server: Public IPv4 address.
    • Instance number: 00.
    • System ID: NPL.

    Once you log on to SAP, you will see the SAP Easy Access user menu on the left-hand side of your screen. This is a user-specific entry point. The user menu only contains those elements that you require for daily tasks.

    You perform SAP configuration via transaction codes. These are related to SAP system functionality. Transaction codes must be input through the SAP command line. For quick access, you can add these to your bookmarks.

  3. Change the default passwords for security:

    1. Using the SAP Easy Access interface, run transaction SU01.
    2. Go to the Logon Data section.
    3. Select the user you would like to edit.
    4. Enter a new password.

Update license

To continue using SAP, you need to update your license:

  1. Using the SAP Easy Access interface, run transaction SLICENSE.
  2. Copy the value in the Active Hardware Key field.
  3. Open the SAP license key page.
  4. Select NPL — SAP NetWeaver 7.x (Sybase ASE).
  5. Specify the form of address. Enter your name, last name, email, and the previously copied Active Hardware Key value.
  6. Accept the terms of the license agreement and download the license file called NPL.tx.
  7. Move the downloaded license file to the VM and add it to the SLICENSE transaction.

Create your first program

To verify system functionality, create a simple program to export the user list.

  1. Log in as DEVELOPER.

  2. Run the SE38 transaction. It is the ABAP Editor.

  3. Call your program ZTEST.

  4. Add a code:

    TYPE-POOLS: slis.

*&---------------------------------------------------------------------*

*& Data Declaration

*&---------------------------------------------------------------------*

DATA: it_usr01     TYPE TABLE OF USR01.
DATA: it_fieldcat  TYPE slis_t_fieldcat_alv,
  wa_fieldcat  TYPE slis_fieldcat_alv.`

*&---------------------------------------------------------------------*

*& START-OF-SELECTION`

*&---------------------------------------------------------------------*
