This guide uses Deployment Manager to deploy all of the required Google Cloud resources to run SAP NetWeaver on Windows Server, including the Compute Engine virtual machine (VM), the Windows Server operating system, and the persistent disks. You define the values for the installation, such as machine type, resource names, disk sizes, and so forth, in a Deployment Manager configuration file template.
If your SAP NetWeaver installation requires more control over the deployment process than the Deployment Manager template provides, see Manual VM deployment for SAP NetWeaver on Windows.
To deploy a VM that is running Linux, see the Linux Deployment Guide.
VM configuration deployed by these instructions
The VM that is deployed by these instructions is for use in a 3-tier configuration, where SAP NetWeaver runs on one VM and the database server runs on another.
To set up a 2-tier configuration, where SAP NetWeaver runs on the same VM as the database server, you deploy the database server first and create the VM and the required disk drives for both the database server and for SAP NetWeaver at that time. You then install SAP NetWeaver on the same VM as the database server.
For instructions about deploying the VM for a database server, see the database deployment guide for your database server.
Google Cloud resources deployed by these instructions
The Google Cloud resources that are deployed by Deployment Manager include:
- A VM that uses an SAP-certified version of Windows Server.
- A persistent disk for SAP binaries.
- A persistent disk for the pagefile.
- The recommended APIs.
- Google Cloud's Agent for SAP.
The following instructions use Cloud Shell, but if you prefer, you can use the Google Cloud CLI in your local terminal instead.
For more details on planning your implementation, see the Planning Guide. For an overview of IT ops for your system, see the Operations Guide.
Creating a project
If you require your SAP workload to run in compliance with data residency, access control, support personnel, or regulatory requirements, then you must create the required Assured Workloads folder. For more information, see Compliance and sovereign controls for SAP on Google Cloud.
To create a project:
- Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
-
In the Google Cloud console, on the project selector page, select or create a Google Cloud project.
-
Make sure that billing is enabled for your Google Cloud project.

Make sure that billing is enabled for your Google Cloud project.
Configuring the gcloud
command environment
These instructions use
Cloud Shell to enter gcloud
commands that deploy or configure
your Google Cloud resources. Cloud Shell is accessed through the
Google Cloud console in your browser.
Cloud Shell runs on a VM that Google Cloud provisions each time
you start Cloud Shell. The first time you use Cloud Shell,
Google Cloud also creates a persistent $HOME
directory for you,
which is restored each time you open Cloud Shell.
The provisioned VM includes the latest
Google Cloud CLI.
Therefore, the gcloud
commands that you use in Cloud Shell are the same as
those you would use in a locally installed instance of the gcloud CLI.
If you have the gcloud CLI installed, you can issue the gcloud
commands that are used in these instructions from your local machine. However,
with a locally installed gcloud CLI you must always make sure that you
are using the latest version of the gcloud CLI.
Whether you use Cloud Shell or gcloud CLI, you
can set and change the properties of your gcloud
command environment and save
them as a configuration. Configurations are collections of key-value pairs
that influence the behavior of the gcloud
commands.
Some basic actions you can take with a configuration in Cloud Shell include:
Initialize a configuration:
gcloud init
Check the settings of your current gcloud configuration:
gcloud config list
Switch to the required Google Cloud project. Replace
PROJECT_ID
with your Google Cloud project ID.gcloud config set project PROJECT_ID
Set a default region. Replace
REGION
with a Google Cloud region.gcloud config set compute/region REGION
Set a default zone. Replace
ZONE
with a Google Cloud zone.gcloud config set compute/zone ZONE
Create a new configuration. Replace
NAME
with the name for the configuration.gcloud config configurations create NAME
For more information about working with configurations, see Managing gcloud CLI configurations.
Creating a network
For security purposes, create a new network. You can control who has access by adding firewall rules or by using another access control method.
If your project has a default VPC network, don't use it. Instead, create your own VPC network so that the only firewall rules in effect are those that you create explicitly.
During deployment, VM instances typically require access to the internet to download Google Cloud's Agent for SAP. If you are using one of the SAP-certified Linux images that are available from Google Cloud, the VM instance also requires access to the internet in order to register the license and to access OS vendor repositories. A configuration with a NAT gateway and with VM network tags supports this access, even if the target VMs do not have external IPs.
To set up networking:
Console
- In the Google Cloud console, go to the VPC networks page.
- Click Create VPC network.
- Enter a Name for the network.
The name must adhere to the naming convention. VPC networks use the Compute Engine naming convention.
- For Subnet creation mode, choose Custom.
- In the New subnet section, specify the following configuration parameters for a
subnet:
- Enter a Name for the subnet.
- For Region, select the Compute Engine region where you want to create the subnet.
- For IP stack type, select IPv4 (single-stack) and then enter an IP
address range in the
CIDR format,
such as
10.1.0.0/24
.This is the primary IPv4 range for the subnet. If you plan to add more than one subnet, then assign non-overlapping CIDR IP ranges for each subnetwork in the network. Note that each subnetwork and its internal IP ranges are mapped to a single region.
- Click Done.
- To add more subnets, click Add subnet and repeat the preceding steps. You can add more subnets to the network after you have created the network.
- Click Create.
gcloud
- Go to Cloud Shell.
- To create a new network in the custom subnetworks mode, run:
gcloud compute networks create NETWORK_NAME --subnet-mode custom
Replace
NETWORK_NAME
with the name of the new network. The name must adhere to the naming convention. VPC networks use the Compute Engine naming convention.Specify
--subnet-mode custom
to avoid using the default auto mode, which automatically creates a subnet in each Compute Engine region. For more information, see Subnet creation mode. - Create a subnetwork, and specify the region and IP range:
gcloud compute networks subnets create SUBNETWORK_NAME \ --network NETWORK_NAME --region REGION --range RANGE
Replace the following:
SUBNETWORK_NAME
: the name of the new subnetworkNETWORK_NAME
: the name of the network you created in the previous stepREGION
: the region where you want the subnetworkRANGE
: the IP address range, specified in CIDR format, such as10.1.0.0/24
If you plan to add more than one subnetwork, assign non-overlapping CIDR IP ranges for each subnetwork in the network. Note that each subnetwork and its internal IP ranges are mapped to a single region.
- Optionally, repeat the previous step and add additional subnetworks.
Setting up a NAT gateway
If you need to create one or more VMs without public IP addresses, you need to use network address translation (NAT) to enable the VMs to access the internet. Use Cloud NAT, a Google Cloud distributed, software-defined managed service that lets VMs send outbound packets to the internet and receive any corresponding established inbound response packets. Alternatively, you can set up a separate VM as a NAT gateway.
To create a Cloud NAT instance for your project, see Using Cloud NAT.
After you configure Cloud NAT for your project, your VM instances can securely access the internet without a public IP address.
Adding firewall rules
By default, incoming connections from outside your Google Cloud network are blocked. To allow incoming connections, set up a firewall rule for your VM. Firewall rules regulate only new incoming connections to a VM. After a connection is established with a VM, traffic is permitted in both directions over that connection.
You can create a firewall rule to allow access to specified ports, or to allow access between VMs on the same subnetwork.
Create firewall rules to allow access for such things as:
- The default ports used by SAP NetWeaver, as documented in TCP/IP Ports of All SAP Products.
- Connections from your computer or your corporate network environment to your Compute Engine VM instance. If you are unsure of what IP address to use, talk to your company's network admin.
- Communication between VMs in a 3-tier, scaleout, or high-availability configuration. For example, if you are deploying a 3-tier system, you will have at least 2 VMs in your subnetwork: the VM for SAP NetWeaver, and another VM for the database server. To enable communication between the two VMs, you must create a firewall rule to allow traffic that originates from the subnetwork.
- RDP connections to your VM instance through port
3389
. - PowerShell connections to your VM instance through port
5986
.
To create a firewall rule:
In the Google Cloud console, go to the VPC network Firewall page.
At the top of the page, click Create firewall rule.
- In the Network field, select the network where your VM is located.
- In the Targets field, select All instances in the network.
- In the Source filter field, select one of the following:
- IP ranges to allow incoming traffic from specific IP addresses. Specify the range of IP addresses in the Source IP ranges field.
- Subnets to allow incoming traffic from a particular subnetwork. Specify the subnetwork name in the following subnets field. You can use this option to allow access between the VMs in a 3-tier or scaleout configuration.
- In the Protocols and ports section, select Specified protocols and
ports and specify
tcp:PORT_NUMBER;
.
Click Create to create your firewall rule.
Deploying a VM for SAP NetWeaver on Windows with Deployment Manager
The following instructions use Google Cloud console, Cloud Shell, and Deployment Manager to deploy a VM instance with Windows Server and all of the persistent disks that SAP NetWeaver requires.
About Deployment Manager
In these instructions, you define the resource options for your installation in a Deployment Manager configuration file template.
Deployment Manager treats all of the resources that are created for your SAP system as a single entity called a deployment. You can view and work with all of the deployments for your project on the Deployments page in the Google Cloud console.
Be aware of the following behaviors when using Deployment Manager:
- Deleting a deployment deletes all of the resources associated with the deployment, including the VMs, the persistent disks, and any SAP systems that are installed on the VM.
By default, Deployment Manager uses the
ACQUIRE
resource creation policy. If you specify a VM name that is already in use by another VM in your project, Deployment Manager doesn't create a new VM, but instead adds the existing VM to your new deployment. If your original VM was created by a previous run of Deployment Manager, the VM is associated with two deployments.If you then delete the new deployment, the acquired VM is deleted from the deployment that originally created it. To avoid such a scenario, either set the Deployment Manager resource policy to
CREATE
, or make sure that you use unique resource names in your new deployment.For information about the policies you can use while creating resources with Deployment Manager and how to specify them, see the Deployment Manager documentation.
Deployment procedure
Open Cloud Shell.
Download the
template.yaml
configuration file template to your working directory:wget https://storage.googleapis.com/cloudsapdeploy/deploymentmanager/latest/dm-templates/sap_nw-win/template.yaml
Optionally, rename the
template.yaml
file to identify the configuration it defines. For example,nw-windows-2016.yaml
.Open the
template.yaml
file in Cloud Shell code editor.To open Cloud Shell code editor, click the pencil (edit) icon in the upper right corner of Cloud Shell terminal window.
In the
template.yaml
file, update the following property values by replacing the brackets and their contents with the values for your installation.Property Data type Description type String Specifies the location, type, and version of the Deployment Manager template to use during deployment.
The YAML file includes two
type
specifications, one of which is commented out. Thetype
specification that is active by default specifies the template version aslatest
. Thetype
specification that is commented out specifies a specific template version with a timestamp.If you need all of your deployments to use the same template version, use the
type
specification that includes the timestamp.instanceName

Integer The size of the pagefile volume. The minimum size is 1 GB. In the deployed VM, this volume is labeled Pagefile (P:). networkTag
String Optional. A network tag that represents your VM instance for firewall or routing purposes. If you specify publicIP: No
and do not specify a network tag, be sure to provide another means of access to the internet.publicIP
Boolean Optional. Determines whether a public IP address is added to your VM instance. The default is Yes
.The following configuration file creates a VM that is configured to run SAP NetWeaver. The configuration file directs Deployment Manager to deploy the
n1-standard-16
VM that is running a Windows Server 2016 operating system. The VM includes all of the directories that are required in order to run SAP NetWeaver.resources: - name: sap-nw-win type: https://storage.googleapis.com/cloudsapdeploy/deploymentmanager/latest/dm-templates/sap_nw-win/sap_nw-win.py # # By default, this configuration file uses the latest release of the deployment # scripts for SAP on Google Cloud. To fix your deployments to a specific release # of the scripts, comment out the type property above and uncomment the type property below. # # type: https://storage.googleapis.com/cloudsapdeploy/deploymentmanager/202103310846/dm-templates/sap_nw-win/sap_nw-win.py properties: instanceName: ex-vm-nw-win instanceType: n1-standard-16 zone: us-central1-f subnetwork: example-sub-network-sap windowsImage: family/windows-2016 windowsImageProject: windows-cloud usrsapSize: 15 swapSize: 24
Deploy the VM:
gcloud deployment-manager deployments create [DEPLOYMENT-NAME] --config [TEMPLATE-NAME].yaml
The above command invokes Deployment Manager, which deploys the VM, all according to the specifications in your
template.yaml
file. The process may take a few minutes. To check the progress of your deployment, follow the steps in the next section.After the VM instance deploys, if you need Compute Engine to save the boot disk in the event the VM instance is deleted:
- Go to VM instances in the Google Cloud console.
- Open VM instance details for your VM instance by clicking the name of the VM instance.
- Under Boot disk and local disks, clear Delete boot disk when instance is deleted.
Verifying deployment
To verify deployment, you check the deployment logs in Cloud Logging.
Check the logs
In the Google Cloud console, open Cloud Logging to monitor installation progress and check for errors.
Filter the logs:
Logs Explorer
In the Logs Explorer page, go to the Query pane.
From the Resource drop-down menu, select Global, and then click Add.
If you don't see the Global option, then in the query editor, enter the following query:
resource.type="global" "Deployment"
Click Run query.
Legacy Logs Viewer
- In the Legacy Logs Viewer page, from the basic selector menu, select Global as your logging resource.
Analyze the filtered logs:
- If
"--- Finished"
is displayed, then the deployment processing is complete and you can proceed to the next step. If you see a quota error:
On the IAM & Admin Quotas page, increase any of your quotas that do not meet the SAP NetWeaver requirements that are listed in the SAP NetWeaver planning guide.
On the Deployment Manager Deployments page, delete the deployment to clean up the VMs and persistent disks from the failed installation.
Rerun your deployment.
- If
After the VM instance deploys, connect to your VM as described in
Connecting to your VM to confirm that all of the
required data volumes exist and that they have the expected capacities. The
Pagefile
drive should be almost full.
If any of the validation steps show that the installation failed:
- Correct the error.
- On the Deployments page, delete the deployment to clean up the VMs and persistent disks from the failed installation.
- Rerun your deployment.
Connecting to your VM
To connect to a Windows-based VM, you must first generate a password for the VM. You can then connect to the VM using RDP or PowerShell.
Generating passwords
In the Google Cloud console, go to the Compute Engine VM instances page.
Click the name of the VM instance for which you need a new password.
On the instance details page, click the Set Windows Password button. A password is generated for you. Copy the password and store it in a secure place.
Using RDP
If your firewall rule allows access
on port 3389
, you can use RDP to connect to a Windows instance and start a
Remote Desktop session. Alternatively, you can
connect to Windows instances using the PowerShell terminal.
Connect to the remote desktop on Windows instances by manually connecting through the Windows Remote Desktop Connection client or a third-party client:
- If you don't already have an RDP client, install one now. For information from Microsoft about available RDP clients, see Remote Desktop clients.
- Get your Windows VM's external IP address. To find the VM IP address, you
can use either of the following methods:
- In the Google Cloud console, go to the VM Instances page.
- Use the gcloud CLI to run
gcloud compute instances list
to list your VM instances with their external IP addresses.
- In your RDP client, provide your VM's external IP address as the IP address to connect to.
- Enter your sign-in information and leave the Domain field blank. If this is your first time connecting to this VM, or if you have forgotten your password, create or reset your Windows password.
Using PowerShell
If you have not created a username and password on the Windows VM yet, create your Windows password.
Add a firewall rule or edit your existing firewall rule to open port 5986 on the VPC network where your Windows Server VM is located.
On your local workstation, open the PowerShell terminal.
Optionally, initialize a variable to hold your user credentials so you do not need to enter them each time you connect to the instance. If you skip this step, you receive a prompt for your username and password later.
$credentials = Get-Credential
Use the Enter-PSSession command to start a remote PowerShell session and include the flags to use SSL and skip credentials checks.
Enter-PSSession -ComputerName [IP_ADDRESS] -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) -Credential $credentials
Setting up the database
If you haven't yet deployed your database on Google Cloud, follow the instructions for setting up your database in both the Google Cloud deployment guide for your database, and in the database documentation that is provided by your database vendor.
Google Cloud provides deployment guides for the following SAP-certified databases:
- SAP HANA guides: when SAP NetWeaver is running on Windows, SAP HANA is supported only in 3-tier architectures.
- SAP ASE guides
- SAP MaxDB guides
- IBM Db2 guides
- Windows SQL Server guide
When SAP NetWeaver and the database server are running on different VMs in a 3-tier architecture, make sure that your firewall rules are defined to allow communication between the VMs.
If you used the Google Cloud-provided Windows image that contains SQL Server, you must change the collation to use the SAP collation.Configuring the Google Cloud Microsoft SQL Server image
If you selected the Google-provided SQL Server Enterprise operating system image
when you created your VM, you must configure SQL Server to use the SAP
collation
(SQL_Latin1_General_CP850_BIN2
) so that SQL Server is compatible with SAP
systems. The default collation in the Google Cloud-provided SQL Server
image is (SQL_Latin1_General_CP1_CI_AS
).
To change the collation after the VM is deployed:
- Connect to your Windows instance by using either RDP or remote PowerShell.
- Sign in to Windows as an admin and stop the
MSSQLSERVER
service. - Go to the directory that contains the binaries for your SQL Server
instance, for example,
C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn
. From an elevated command prompt, change the collation by running:
sqlservr -m -T4022 -T3659 -s"[SQL_SERVER_INSTANCE_NAME]" -q"SQL_Latin1_General_CP850_BIN2"
where:
- The parameter
-m
starts the SQL Server instance in single-user mode. - The trace flag
4022
forces SQL Server to skip any stored startup procedures. - The trace flag
3659
allows all errors to be logged to the SQL Server logs. - The parameter
-s
specifies the name of the SQL Server instance to start. Replace[SQL_SERVER_INSTANCE_NAME]
with your SQL Server instance name. - The parameter
-q
rebuilds all databases and objects to the specified SAP collation, without reinstalling the instance or rebuilding system databases.
- The parameter
Restart the SQL Server Service
MSSQLSERVER
after the collation is changed.Confirm your change in the most recent SQL Server
ERRORLOG
or the server's collation properties.
