This guide covers the installation and configuration of the Google Cloud Connector for SAP Landscape Management (Connector for LaMa), as well as operational tasks after the connector is installed.

To install and configure the Connector for LaMa, you perform the following high-level steps:

  • Configure authentication and authorization to the Google Cloud APIs.
  • Download the installation archive from Google Cloud.
  • Install the Connector for LaMa on the same host as SAP Landscape Management. The host can be either a Compute Engine virtual machine (VM) or a virtual or physical machine that is not on Google Cloud.
  • Configure the Cloud Manager for Google Cloud functionality in SAP Landscape Management.
  • Install storage library and operations files on each VM that hosts an SAP system to be managed by SAP Landscape Management.


Before you can install the Connector for LaMa, you need to install and configure a supported version of SAP Landscape Management. For the supported versions, see Software requirements.

Install SAP Landscape Management according to the SAP Landscape Management installation guides and the SAP Landscape Management Adaptive Design principles.

For more information, see:

Configure authentication and authorization to the Google Cloud APIs

You need to configure CA certificates and, if you need tighter access control, an IAM service account.

Upload CA Certificate for Google API communication

The Connector for LaMa requires a CA certificate to communicate with the Google Cloud APIs. Make sure the following certificates are available in the Trusted CAs view of the SAP NetWeaver Java KeyStore Storage view.

  1. Go to the Google Trust Services repository at

  2. In the Download CA certificates section under Subordinate CAs, download CA certificate GTS CA 1C3.

  3. Import the certificate by following the instructions in the SAP NetWeaver documentation: Using the AS Java Key Storage.

Create an IAM service account

Unless you intend to use the service account of the hosting VM instance as the default service account, you need to create an IAM service account for the Connector for LaMa.

To create a service account for the Connector for LaMa:

  1. In the Google Cloud console, go to the Service accounts page:

    Go to Service Accounts

  2. Select your Google Cloud project.

  3. Click Create Service Account.

  4. Specify a name for the service account and, optionally, a description.

  5. Click Create and Continue.

  6. On the Grant this service account access to project step, grant the service account a role that contains all of the permissions that SAP Landscape Management requires. A role can be a predefined role, like Compute Admin, or a custom role that you create that contains the permissions that are listed in Required IAM resource permissions for the Connector for LaMa.

  7. Click Done.

  8. On the Service accounts page in the Google Cloud console, click on the service account that you just created.

  9. Under the service account name, click the Keys tab.

  10. Click the Add Key menu, and then select Create new key to create a service account key.

  11. Accept JSON as the key type and click Create. A private key is saved to your computer. Store the JSON key file in a safe place. Later, when you configure the Cloud Manager function SAP Landscape Management, you copy and paste the contents of the key file into SAP Landscape Management.

Set the JVM to use Internet Protocol version 4

To use fully-qualified host names, in SAP Landscape Management monitoring settings, select the Use FQDN Hostnames Only checkbox. For more information, see Configuring Monitoring Settings.

Install Google Cloud's Agent for SAP

For support and monitoring, Google Cloud provides the Agent for SAP, for SAP workloads running on Compute Engine VM instances and Bare Metal Solution servers.

As mandated by SAP, to get support from SAP and to enable SAP to meet its service-level agreements (SLAs), you must install Google Cloud's Agent for SAP on all Compute Engine VM instances and Bare Metal Solution servers with any SAP system. For more information on the support prerequisites, see SAP Note 2456406 - SAP on Google Cloud Platform: Support Prerequisites .

Google Cloud's Agent for SAP version 1 is the successor of Google Cloud's monitoring agent for SAP NetWeaver version 2. In addition to the mandatory collection of SAP Host Agent metrics, the new version of the agent includes optional functionalities such as collection of Process Monitoring metrics and Workload Manager validation metrics. You can opt in to these functionalities that enable products and features such as workload management for your SAP workloads.

You install Google Cloud's Agent for SAP on the host alongside the SAP system. For the instructions about how to install and configure the agent, validate your installation, and verify that the agent is running properly, see Install and configure Google Cloud's Agent for SAP on a Compute Engine VM instance.

Install the OS storage library and operation definitions on the managed VMs

The gcp-connectorversion.tar file includes an OS storage library and operation definitions with their corresponding scripts.

You need to install the OS storage library and operation files on each VM instance that is managed by SAP Landscape Management.

To install an OS storage library and operation definitions on a VM that is managed by SAP Landscape Management:

  1. Download or copy the gcp-connectorversion.tar file to the target VM.
  2. Extract the files in the gcp-connectorversion.tar file into a temporary directory.
  3. Run the installation script:

    • On Linux, enter:
      sudo bash
    • On Windows, with administrative privileges enter:

    The install script copies the OS storage library to the directory of the active SAP Host Agent, /usr/sap/hostctrl/exe and the operations files to a subdirectory, /operations.d. The script sets file ownership to root:sapsys and sets appropriate access rights for each file type.

    file ./storage/ copied to /usr/sap/hostctrl/exe/
    file ./storage/Operations/AcActivateIP copied to /usr/sap/hostctrl/exe/operations.d/sapacosprep/AcActivateIP
    file ./storage/Operations/AcDeactivateIP copied to /usr/sap/hostctrl/exe/operations.d/sapacosprep/AcDeactivateIP
    file ./storage/Operations/ copied to /usr/sap/hostctrl/exe/operations.d/sapacosprep/
    file ./storage/Operations/ copied to /usr/sap/hostctrl/exe/operations.d/sapacosprep/

  4. After deployment, restart SAP Landscape Management.


By default the SAP Landscape Management system operates on Google Cloud by using the identity of an IAM service account. If you experience authorization errors, first try using gcloud commands to perform the same action that is receiving the error from within the guest operating system. For example:

SAP Landscape Management action Equivalent gcloud command
Stop/start gcloud compute instances stop/start
Clone gcloud compute disks snapshot
gcloud compute disks create
Relocate gcloud compute instances attach-disk
gcloud compute instances detach-disk

The gcloud command output provides you with an indication of whether you are missing authorizations to execute a particular action. If this is successful, but your error persists, contact Support as described in the following section.


If you come across issues with the operation of your SAP Landscape Management system that you need help to resolve, please log a support message via the SAP Support Portal under component BC-VCM-LVM.

If you determine that the root cause of the issue is in the Connector for LaMa, select sub-component BC-VCM-LVM-GOOGLE; however, if you are unsure of the cause of a problem, choose component BC-VCM-LVM, so that SAP support can analyse the issue first.

Information to include:

  • The SAP Landscape Management version
  • The Connector for LaMa version
  • The SAP NetWeaver kernel version
  • The version of the managed SAP system, including the version of the host agent
