Oracle On Prem to Azure Sql Database Migration

Question

Hi,

I am performing the migration from oracle on premises to the azure sql database.

Scenario-1

Oracle- Connected to Self Hosted Integration Runtime

Azure sql database-Connected to Azure Managed Virtual Network Integration runtime

Firewall port open from the ADF SHIR virtual machine to the Azure sql server.

Migration happens successfully.

Question-1-Scenario-2

Oracle- Connected to Self Hosted Integration Runtime

Azure sql database-Connected to Azure Managed Virtual Network Integration runtime

Firewall port open NOT OPEN from the ADF SHIR virtual machine to the other Azure sql server.

Migration does not happens.

It is due to firewall request issues or some other issues.

With oracle on prem connected to the ADFSHIR and Azure sql database connected to Azure Managed Virtual Network Integration runtime can i do the data migration or the above firewall request from ADF SHIR VM to the azure sql server database is necessary ?

While individually i am able to connect to the azure sql database and deploy the scripts using the script activity.

Error Message-ErrorCode=SqlFailedToConnect,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Database. Please contact SQL server team for further support. Server: '', Database: '', User: '*'.**

Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.

Answer 1

Hello Kashish,

In your second scenario, you were not able to perform the migration because the firewall port was not open from the ADF SHIR virtual machine to the Azure SQL server. This prevented the integration runtime from accessing the Azure SQL server and performing the migration.

To perform the migration from Oracle on-premises to Azure SQL Database, you need to make sure the integration runtime has access to the Azure SQL server.

To resolve this, you can add the IP address of the ADF SHIR virtual machine to the firewall settings on the Azure SQL Database server.

I hope this helps.
