This document covers the step by step procedure to set up and configure SAP on Oracle ASM (Oracle Linux 8.2 /Oracle 19c) on Azure . As this setup involves a large number of steps, it is very easy to miss or misconfigure ,that may result in errors/issues ,which could be very cumbersome to resolve. Hence these steps are covered here in detail. Since we are talking about the Oracle ASM install, scope of this document is restricted to SAP DB instance install.

 High Level Process Flow :

  1. Create VMs

  2. Patch OS and pre-install

  3. Create disks

  4. Setup ASM

  5. DB Install with SWPM

  6. Oracle software installation

  7. SBP Oracle DB instance

  8. SBP Oracle Grid

  9. Confirm patching successful + run Oracle Enterprise Manager

Deploy Linux VMs

via Azure portal

  1. Create a Resource Group

  2. Create a Virtual network

  3. Use the Virtual Network create above

  4. Create Virtual Machine 1 for App server . Virtual Machine 2 for ASCS server, Virtual Machine 3 for DB server .Use at least Oracle Linux 8.0 image from azure marketplace image gallery. In this example Oracle Linux 8.2 image is used.

via Azure CLI

     1. Login to Azure

        az login

  1. Create a resource group

         az group create –name oraasmtestrg   –location <location>

3. Create a virtual machinesaz group create


App server

az vm create –resource-group oraasmtestrg  –name oraapp1 –image Oracle:Oracle-Linux:ol8_2-gen2:8.2.01 –size Standard_E4s_v3 –admin-username sapadmin –admin-password <password>  –location southeastasia –vnet-name oraasmtestvnet –subnet default


az vm create –resource-group oraasmtestrg  –name oraascs1 –image Oracle:Oracle-Linux:ol8_2-gen2:8.2.01 –size Standard_E4s_v3 –admin-username sapadmin –admin-password <password>  –location southeastasia –vnet-name oraasmtestvnet –subnet default

Database server:

az vm create –resource-group oraasmtestrg –name oradb7 –image Oracle:Oracle-Linux:ol8_2-gen2:8.2.01 –size Standard_E8s_v3 –admin-username sapadmin –admin-password <password> –data-disk-sizes-gb 512 512 512 512 –location southeastasia –os-disk-size-gb 128 –vnet-name oraasmtestvnet –subnet default

Jump server

az vm create –resource-group oradgsap-rg –name oradgjmp-vm –image win2016datacenter–size Standard_E2s_v3 –admin-username sapadmin –admin-password <password> –location < location> –vnet-name oraasmtestvnet –subnet default

It is a good practice to disable the public Ip Addresses of SAP VMs. You can access these VMs from Jump box via private Ip Addresses


OS configuration and pre-install

Resize OS disk 

The default provisioned size of OS disk on Linux Vm on azure is 30GB which is not sufficient for the Oracle install. As the OS selected is Oracle Linux 8.2 which has GPT partition in OS disk, follow the steps here  to resize the OS Disk with GPT partition

Install ASM libraries 

 Refer Oracle ASMLib Downloads for Oracle Linux 8  For more information about installing Oracle ASM libraries.

    • Login as root for install

sudo su –

    •  Update the OS

 sudo yum update

    • Download and install the Oracle Preinstallation RPM:

# yum -y install oracle-database-preinstall-19c

# rm oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

    • Install Oracle ASM libraries

yum list | grep oracleasm


    • Verify that Oracle ASM is installed:

rpm -qa |grep oracleasm

    • This should result in following output



    • Verify users and groups were created correctly:

id oracle

    • This should result in following output similar to the following:

id=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54334(asmdba),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba),54331(sapinst),54332(asmoper),54333(asmadmin)


Setup Oracle ASM

  • Create a folder for user oracle and change the owner:

mkdir /oracle

chown oracle:oinstall /oracle

  • Setting up the Oracle ASM library driver involves defining the default user (oracle) and default group (oinstall) as well as configuring the drive to start on boot (choose y) and to scan for disks on boot (choose y). You need to answer the prompts from the following command:

# oracleasm configure -i

  • The output of this command should look similar to the following, with prompts to be answered:oracleasm.jpg




  • View the disk configuration:

cat /proc/partitions


  • Enter the following command to load the oracleasm kernel module

# oracleasm init


  • Verify the Oracle ASM status:

  • oracleasm status

  • Format disk /dev/sda, /dev/sdb, /dev/sdc, /dev/sdd  by running the following commands      

   fdisk /dev/sda

   fdisk /dev/sdb

   fdisk /dev/sdc

   fdisk /dev/sdd

  • Answer the prompts from the above fdisk commands with:

n for new partition

p for primary partition

1 to select the first partition

press enter for the default first cylinder

press enter for the default last cylinder

press w to write the changes to the partition table


  • Create Oracle ASM disks:

oracleasm createdisk DATA_DISK_01 /dev/sda1

oracleasm createdisk DATA_DISK_02 /dev/sdb1

oracleasm createdisk ARCH_DISK_01 /dev/sdc1

oracleasm createdisk RECO_DISK_01 /dev/sdd1


  • List Oracle ASM disks:

oracleasm listdisks

  • Change the passwords for the root and oracle users:

passwd oracle

passwd root

  • Change the directory permissions:

chmod -R 775 /oracle

chown grid:oinstall /oracle

chown oracle:oinstall /dev/sda1

chown oracle:oinstall /dev/sdb1

chown oracle:oinstall /dev/sdc1

chown oracle:oinstall /dev/sdd1

chmod 600 /dev/sda1

chmod 600 /dev/sdb1

chmod 600 /dev/sdc1

chmod 600 /dev/sdf1


DB Instance Install(SWPM)

Before we begin the DB instance install , mount the sapmnt (NFS share) directory which must have been created during the ASCS instance setup.


  • Install NFS libraries
               sudo yum -y install nfs-utils

  • Create sapmnt directory and mount remote NFS file system
                mkdir /sapmnt
                mount <<ip of NFS server>>:/sapmnt  /sapmnt

  • Every host running the SAP installer requires the presence of the C shell command language interpreter as documented a. here. Verify the existence of the /bin/csh script file. When not existing install using following command:
                yum install csh

  • Verify that the /bin/csh script file exists using the following command:
                ls -al /bin/csh

  • Start the SAP SWPM installer and select the appropriate options:
    Software Provisioning Manager 1.0 SP 29 –> SAP NetWeaver 7.5 –> Oracle à Application Server ABAP–> Distributed System –> Database Instance

  • Specify the profile directory


  •  Specify the DBSID and select the ‘Single Instance on Oracle ASM 




  • You may see this error – “Supported Linux distributions for SAP Products…” .This can be safely ignoredasm-OSerror1.jpg

  • Select 19 as Oracle server and client versions.


  • Select ‘Remove database and recreate’ 



  • Enter ORACLE_HOME and ORACLE_SID  for GRID and select “Oracle Grid Software not installed”


  • Select the Number of parallel jobs based on the CPU cores. The default number is 3               


  •  SWPM stops for the installation of Oracle software




 Oracle Grid Install 

  • Download the following from SAP portal as documented in SAP Note 509314

An empty folder /oracle/stage/19 is created by SWPM installer. We downloaded the grid and oracle rdbms installer into this folder

  • Run the grid installer setup .Login as oracle and unzip the grid installer:
          cd /oracle/stage/19/grid_home
          unzip -q

  • Run the grid installer setup .This would launch Oracle Grid Infrastructure Setup Wizard
          ./gridSetup.shCurrently we have a known issue with Oracle 8.2 install.The Oracle Installer fails with error INS-08101:

  • Currently we have a known issue with Oracle 8.2 install.The Oracle Installer fails with error INS-08101:


The work around to resolve this is:
⦁ Set the OS parameter in your terminal to a previous version and re-start the Oracle Universal Installer.

  • Enter the Disk group name for DATA, select the disk path of Data disks and set the discovery path (e.g. ‘dev/oracleasm/disks/):

  • Specify the password for ASM user accounts (SYS and SNMP)




  • Select name of operating system group,which you want to use for system authentication to Oracle ASM


  • Select the path for Oracle base


  • Select Oracle inventory directory path


  • If you choose to run the configuration scripts automatically , specify the ‘root’ user credentials


  • Verify the settings and click Next to finish




We have just configured/created  data group named ‘DATA’  .. To configure other disk groups (ARCH and RECO) , we use ASM Configuration Assistant tool.

  • To start ASMCA, enter asmca at a command prompt inside the Oracle Grid Infrastructure home.
           cd $ORACLE_HOME/bin
