- An SAP BTP account
- An SAP HANA Cloud instance
- Step 1
The SAP Automation Pilot is a service within the SAP BTP that can be used to schedule and automate tasks.
Once subscribed to the service, the tool can be opened by clicking on the application link.
It provides a visual tool for constructing commands.
The SAP Automation Pilot provides the following catalogs to aid in managing an SAP HANA Cloud instance:
-
sm-sapcp contains commands to perform tasks within a BTP subaccount.
-
dblm-sapcp contains commands to start, stop, or upgrade an SAP HANA Cloud instance provisioned in Cloud Foundry.
-
cf-sapcp contains commands to perform tasks within Cloud Foundry.
-
sql-sapcp contains a command to execute SQL commands.
SQL commands can also be executed in a Python application running in the SAP Automation Pilot. For additional details, see Execute SQL Commands and Create Custom Notifications with SAP Automation Pilot and SAP Alert Notification Service.
-
http-sapcp contains commands to execute HTTP requests such as REST calls to retrieve metrics or alerts about SAP HANA Cloud instances. Details of the REST APIs relevant to SAP HANA Cloud instances can be seen at the Business Accelerator Hub.
In addition, SAP Automation Pilot provides an option to schedule commands and provides integration with the SAP Alert Notification service which is used to send an email or create an incident in various ticketing systems. If you do not already have the SAP Automation Pilot configured, step 1 of the tutorial Take Action Following a SAP HANA Cloud Database Alert with SAP Automation Pilot and the tutorial Get Started with SAP Automation Pilot demonstrate how to get started.
-
- Step 2
The catalog below contains examples of commands and inputs for those commands that can be used to automate SAP HANA Cloud tasks.
-
Import the catalog below into the SAP Automation Pilot.

Should you wish to delete this catalog, perhaps to import a newer version, press the Edit Multiple button for both commands and inputs as a non empty catalog cannot be deleted.
-
Examine the imported commands and inputs. The list of commands are shown below.
The list of inputs are shown below. Notice that the names that start with CF are for instances that were provisioned to Cloud Foundry.
-
Trigger the ExampleCommand. It provides an array input of [1, 2, 3, 4, 5] and transforms the input using dynamic expression which uses jq. A playground is available for jq at jq play.
Further examples can be found at automation pilot examples.
-
- Step 3
The examples shown include commands to start, stop, update, access instance metrics, and upgrade an SAP HANA Cloud instance. The commands make use of a common input parameter that specifies the instance to target.
-
Modify the input key InstanceDetails to match the SAP HANA Cloud instance that you wish to work with.
-
The instanceBindingKey value is required the by the MetricRequest command and comes from a service binding key created on an SAP HANA Cloud instance.
-
The smBindingKey value is required for the MassUpgradeHC command and comes from a binding on a service manager instance that was created in the previous tutorial.
-
-
The commands StartHC and StopHC can be used to start and stop a SAP HANA Cloud instance.
-
Open the command StartHC.
-
Examine the Additional Values section for the input. Notice that it has as its inputs InstanceDetails which describes which SAP HANA Cloud instance to target and Start which contains the JSON that specifies how to update the serviceStopped state.
-
Examine the executor named update. Notice that it makes use of one of the provided commands
sm-sapcp:UpdateServiceInstanceand that its inputs are taken from inputs just examined.
-
Trigger the command.
No additional inputs are required.
The command will then complete, and its status can be examined.
The status of the SAP HANA Cloud instance will update to Starting.
-
-
Open the command UpdateHC. It can be used to perform an update of an SAP HANA Cloud instance.
-
Examine the Description input parameter. This parameter describes the change that will be made.
In this case the update will be to the description of the instance but other parameters could be updated as described at Parameter Reference.
-
Trigger the command. Once the command has completed, the description will appear as shown below in SAP HANA Cloud Central.
-
-
Open the command CheckMetric. It can be used to access a metric value from an SAP HANA Cloud instance. In this example, the metric HDBConnectionCount will be used which returns the number of open SQL connections and is measured every 60 seconds for the previous hour. The command will request these metrics and then count the number of occurrences where the number of open connections was above a specified threshold. Additional details on accessing database metrics using a REST API can be found at Access SAP HANA Cloud Alerts and Metrics using a REST API. Before proceeding, add a service binding to the SAP HANA Cloud instance that will be used as described in the step 1, substep 1 of the tutorial mentioned above.
-
Examine the InstanceDetails input parameter. This parameter contains an instanceBindingKey which contains the service binding for an SAP HANA Cloud instance. The contained credentials (clientid and clientsecret) will be used to access the metrics API.
-
Examine the getToken executor. It is used to get a bearer token that can be used as authentication when invoking a REST API call against the metrics or alerts APIs. It makes use of the values uaa.url, clientid, and clientsecret from the instanceBindingKey.
-
Examine the metricRequest executor. It is used to get the metric HDBConnectionCount and uses the bearer or access token returned from the previous executor.
The URL used will need to be updated to match your environment. Note the default URL uses prod-us10.
-
Examine the command’s output.
-
Trigger the command and view the output. Notice that in the last hour, the number of open SQL connections exceeded 100 four times.
This example could be further extended by scheduling this check to run on a set schedule and to send an email if the count was above a certain threshold.
It should be noted that connection details are also available in the system view M_CONNECTIONS. The number of currently open connections can be determined by using a SQL query such as the one shown below.
SQLCopySELECT * FROM PUBLIC.M_CONNECTIONS WHERE END_TIME is NULL; -
-
Open the command UpgradeHC. This command takes an input parameter to specify the instance to target. It can be used to perform an upgrade of an SAP HANA Cloud instance and selects the instance to upgrade to from a value returned by a call to GetInstanceParameters. This command could then be scheduled to run nightly or weekly which would then keep the SAP HANA Cloud instance running using the latest available patch or update.
-
Prior to triggering the command, examine the instance in SAP HANA Cloud Central.
-
Trigger the command and examine the output.
-
Once the command completes, the notification that there is a new version available will disappear and the new version will be shown in SAP HANA Cloud Central.
-
If there is not an available version to update to, an error message is shown.
This check is performed in the validation step of the command getParams.
This is performed using a dynamic expression which uses jq. A playground is available for jq at jq play.
-
Additional customization can be performed in the generateJSON command.
If no further customization is needed, the JSON could instead be specified directly in the parameter parameters in the upgrade executor using the below JSON.
JSONCopy{ "data": { "productVersion": { "releaseCycle": "generally-available-quarterly", "track": "$(.getParams.output.CommandOutput.availableUpgradeVersions[0].track)", "id": "$(.getParams.output.CommandOutput.availableUpgradeVersions[0].id)" } } }
-
-
Open the command MassUpgradeHC. This command takes two input parameters. The parameter InstanceDetails includes the smBindingKey which is used for authentication and the servicePlanId is used as a filter to return only SAP HANA Cloud instances in the getInstances executor. The parameter Upgrade specifies the product version that should be used when upgrading the list of SAP HANA Cloud instances.
-
Prior to triggering the command, examine the instances in SAP HANA Cloud Central and note any instances that have an upgrade available to them.
-
The getInstances executor returns the list of SAP HANA Cloud instances that have been deployed to the subaccount. It does not include instances deployed to a Cloud Foundry space.
-
The upgrade executor loops through the list of instances returned by getInstances and attempts to upgrade each instance.
-
After triggering the command, examine the instances in SAP HANA Cloud Central and note that they now have been upgraded to the specified version.
-
The output of the command also indicates the list of instances found.
-
-
- Step 4
The examples shown include commands to start, stop, update, and upgrade an SAP HANA Cloud instance. The commands make use of two common input parameters that specify the instance to target and the credentials to use.
-
Modify the input keys to match the SAP HANA Cloud instances that you wish to work with.
-
Open CFInstanceDetails.
The values can be found on the Overview page of the subaccount page. Note that guid values can also be used for the Cloud Foundry Org name and space name. Ensure that there is not a new line character following the values to ensure that an error message about the URL being malformed does not occur.
-
Open CFTechnicalUser.
Enter your Cloud Foundry user and password. The user must not have two factor authentication enabled.
-
-
The commands CFStartHC and CFStopHC can be used to start and stop a SAP HANA Cloud instance.
-
Open the command CFStartHC.
Notice that it has as its inputs CFUser which provides the technical user details and CFInstanceDetails which describes which SAP HANA Cloud instance to target.
Notice that the executor named CFStartHC makes use of one of the provided commands
dblm-sapcp:StartHanaCloudInstanceand that its inputs are taken from inputs just examined.
-
Trigger the command.
No additional inputs are required.
The command will then complete, and its status can be examined.
The status of the SAP HANA Cloud instance will update to Starting.
-
An addition example that demonstrates how to perform start and stop operations on multiple instances at once is available at Mass Stop/Start HANA Cloud Databases.
-
-
Open the command CFUpdateHC. The command can be used to perform an update of an SAP HANA Cloud instance.
-
Examine the Description input parameter. This parameter describes the change that will be made.
In this case the update will be to the description of the instance but other parameters could be updated as described at Parameter Reference.
-
Trigger the command and notice that the description will appear as shown below in SAP HANA Cloud Central after the command has finished executing.
-
-
Open the command CFUpgradeHC. It can be used to perform an upgrade of an SAP HANA Cloud instance. This command takes two input parameters; one to specify the instance to target and another for the credentials to use. The command can be used to perform an upgrade of an SAP HANA Cloud instance and selects the instance to upgrade to from a value returned by a call to GetCfServiceInstance. This command could then be scheduled to run nightly or weekly which would then keep the SAP HANA Cloud instance running using the latest available patch or update.
-
Prior to triggering the command, examine the instance to be upgraded in SAP HANA Cloud Central.
-
Trigger the command and examine the output once it completes.
-
In SAP HANA Cloud Central, the notification that there is a new version available will disappear and the new version will be shown.
-
If there is not an available version to update to, an error message is shown.
This check is performed in the validation step of the command getParams.
This is performed using a dynamic expression which uses jq. A playground is available for jq at jq play.
-
Additional customization can be performed in the generateJSON command.
If no further customization is needed, the JSON could instead be specified directly in the parameter parameters in the upgrade executor using the below JSON.
JSONCopy{ "data": { "productVersion": { "releaseCycle": "generally-available-quarterly", "track": "$(.getParams.output.parameters.availableUpgradeVersions[0].track)", "id": "$(.getParams.output.parameters.availableUpgradeVersions[0].id)" } } }An additional upgrade example is available at Patch Update of HANA Cloud Database.
