Storage management supports Synapse Dedicated SQL Pools in Azure. Storage Management automatically creates Synapse tables with round-robin distribution and can load them with data when used in combination with ADLS Gen2. It can also be used to query data back to SAP.
General Prerequisites
SAP NetWeaver release
Storage management requires SAP NW 7.01 SP15 or higher.
Open Ports
In a controlled network environment, it is common to have firewall rules in place. To enable communication between SAP systems and Azure, outbound communication from the SAP system to the following ports on the Azure side needs to be allowed:
Port | Type | AWS service |
---|---|---|
1433 | TCP | Synapse Dedicated SQL pool endpoint |
80/443 | HTTP/HTTPS | ADLS Gen2 endpoint |
Storage Management allows encrypted communication through the public internet with Azure services, but for production deployment, it is recommended to have some kind of secure connectivity in place (VPN, Private Link, Private endpoints).
Java connector
Java connector is a critical middle-ware component used for processing SQL statements as well as facilitating communication with selected file storage services. Follow the steps described in the article Java Connector Setup to set it up before you continue.
The minimum required Java connector version is 222.
and library version supporting the msal4j library (optional for OAuth 2.0 Authentication).
ADLS Gen 2 storage
ADLS storage is required as storage for temporary data. Follow this guide to create the storage Azure Data Lake Gen2.
When you use OAuth2 authentication for ADLS, it can be reused also for Synapse.
Synapse storage
You need to create resources on Azure and set up authentication and authorizations. After that, you need to set connection details in Storage Management.
Create a Dedicated SQL pool
To get connectivity details for your SQL pool, enter your SQL pool Azure resource and go to Connection Strings.
Write down the above-highlighted information from the JDBC connection string: server hostname, database, and the user which will be used in the SM storage definition.
Create Schema (optional)
You can create a custom schema, otherwise, DBO is used.
Create DB user
a) OAuth 2.0 authentication
To use OAuth authentication using the same user that is set in the ADLS Gen2 storage, you need to add the user to Synapse and give him privileges for the database.
CREATE USER [app-glue-synapse-connector] FROM EXTERNAL PROVIDER; // app-glue-synapse-connector is an example Azure AD app. registration EXEC sp_addrolemember 'db_owner', 'app-glue-synapse-connector'; |
b) Database user authentication
The other option is to use authentication using standard database users. You can use the built-in admin created during pool creation, or a dedicated technical user created later on.
// switch to Master database CREATE LOGIN "app-datavard-connector" WITH PASSWORD = 'FovAy>pCYW%%WX'; // create your technical user and password //switch to the working database CREATE USER "app-datavard-connector" FOR LOGIN "app-datavard-connector"; EXEC sp_addrolemember 'db_owner', 'app-datavard-connector'; |
Download the JDBC driver for the SQL server
Download the JDBC driver from the MS JDBC Download site. Upload the .jar file to the SAP application server at /sapmnt/<SID>/global/security/dvd_conn/mssql/
The file needs to be owned by <sid>adm:sapsys
$ ls -ld /sapmnt/DVQ/global/security/dvd_conn/* drwxr-xr-x 2 dvqadm sapsys 4096 --- /sapmnt/DVQ/global/security/dvd_conn/mssql $ ls -l /sapmnt/DVQ/global/security/dvd_conn/mssql drwxr-xr-x 2 dvqadm sapsys 4096 --- /sapmnt/DVQ/global/security/dvd_conn/mssql/mssql-jdbc-9.2.1.jre15.jar
Create Synapse storage in Storage Management
You can choose between two authentication methods: database user/password, and oAuth2.0 credentials. For production environments, it is recommended to use oAuth.
Go to transaction /DVD/SM_SETUP
