Migrating On-Premises Oracle Database to Azure Cosmos DB

Migrating an on-premises Oracle Database to Azure Cosmos DB can be challenging, but it can also be incredibly beneficial in the long run. In this section, we’ll explore the popular “Lift and Shift” migration method and the steps involved in connecting to Azure Cosmos DB, creating a new database, migrating data, and re-pointing DNS. We’ll also touch on the importance of a successful migration outcome and how it can streamline and optimize your database navigation with Azure Cosmos DB.

“Lift and Shift” Migration Method

Migrating an Oracle Database to Azure Cosmos DB can be easy with “Lift and Shift”. This method uses the existing database without any changes and deploys it in the cloud.

To start, connect to Azure Cosmos DB and create a new database.

No complex code rewriting or changes to the database schema are needed with “Lift and Shift”. This makes the migration faster. But, following best practices is essential for successful deployment.

Azure Data Factory or Azure Synapse Analytics are recommended for moving the data, depending on the requirements. Working with a knowledgeable network partner can further improve the timeline.

Creating a new database on Azure Cosmos DB makes the migration from Oracle simpler and more cost-effective.

Connecting to Azure Cosmos DB and Creating a New Database

1. To link to Azure Cosmos DB and build a new database, take these steps.
2. Log in to the Azure portal using your credentials.
3. Create a Resource Group for Azure Cosmos DB customers.
4. Select ‘For Data Storage’ and locate ‘Azure Cosmos DB‘ in the category.
5. Fill out the info, choose the location, API type, consistency level, pricing tier, and apply tags.
6. Tap ‘OK‘ to create the resource.
7. It’ll take some time before it appears in the resource groups.

Be sure to choose the correct pricing tier for data size and usage limits. Think about projections like number of collections, throughput consumption values for optimal performance.

Remember this when making new resources through Azure Cosmos DB: On free subscription tiers or pay-as-you-go models, you can provision up to four databases. After you reach that sum, if you try to make more, you’ll have to pay for more databases.

Developers: CData Software provides ODBC Drivers/Connectors for over 180+ SaaS/cloud services including Cosmos DB. These drivers speed up SQL access to NoSQL platforms like Cassandra, HBase, MongoDB, Elasticsearch, and more. They can reduce integration costs during software development projects.

Migrating Data and Re-Pointing DNS to Azure Cosmos DB

Migrating data and re-pointing DNS to Azure Cosmos DB is complex. The 1st step is to prepare the source Oracle database with RMAN or other backup tools. Make an instance of Azure Cosmos DB with an appropriate API for Oracle data. Through either the Azure portal or the Azure CLI.

Security checks come next. Configure firewall rules to allow traffic from the source Oracle database to the new Azure Cosmos DB one. This helps the migration process to be successful and secure.

Migrate the data from on-premises Oracle to Azure Cosmos DB with a tool that supports both databases, like Azure Database Migration Service. This ensures all data is transferred accurately.

Configure apps so they point to the new location of the database on Azure Cosmos DB instead of the old one. Apps may need configuration changes so they can connect.

Update DNS records to point users and clients to the newly migrated Azure Cosmos DB database instance. This helps them access the data.

Throughout the migration process, make sure you have easy access to information about your Cosmos DB or Oracle database. Export files or manuals, they can be used in each task.

However, keep in mind factors like network bandwidth, source platform limits, infra constraints, etc. can affect these features. The Oracle Connector still provides great capabilities for data migration.

Note on Oracle Proxy Server

Migrating to Azure Cosmos DB requires the Oracle Proxy Server. It ensures secure communication with on-premises clients and the cloud database. To do this, users need SSL certificates from the Azure Portal. Additionally, they need a Direct Internet connection to access the cloud database or other AWS public services.

The Oracle Proxy Server requires Oracle Integration Runtime (IR) V2 or above, which needs to be set up before migration. There are multiple versions of the software, including some with minor bugs and undocumented server parameters. These could affect HTTPS connections.

Note on Self-Hosted Integration Runtime

Want to connect to Oracle and transfer data through Azure Data Factory or Synapse? Consider the Self-Hosted Integration Runtime. It’s complex, but this section will help you understand how it works.

Windows, Linux, and Docker containers are supported. You’ll need JDK 8+, Python 2.7/3.6/3.7/3.8, and .NET Core Runtime 2.1+. You’ll also need to configure settings like port number, runtime proxy, etc.

Most importantly, it provides secure communication between on-premises and cloud-based services like Cosmos DB. So, you can migrate data safely.

In summary, this section gives a comprehensive guide to using the Self-Hosted Integration Runtime for Oracle-related tasks in Azure. Don’t forget to explore the Managed Virtual Network Integration Runtime for more networking fun!

Using Managed Virtual Network Integration Runtime

MVNIR: Managed Virtual Network Integration Runtime provides a secure and reliable way to copy data from Oracle to Azure Cosmos DB. With MVNIR, traffic is encapsulated into a VNet tunnel for extra security. Setting it up requires creating an integration runtime and associating it with a VNet. Then, install it on a VM in the target VNet which meets the required standards.

Once configured, MVNIR can copy data from Oracle databases to both single and multi-master Cosmos DB accounts. It uses the Oracle database connector via ODBC to read from tables and write data to collections.

Prior to setting up MVNIR, ensure you have the right permissions and credentials for accessing the source and target resources. Microsoft documentation has detailed instructions for configuring MVNIR integration runtime.

In conclusion, MVNIR offers a secure and efficient way to connect to remote Oracle databases using ODBC for Azure-based services.
