Migrating from Oracle to Amazon S3 Key Steps and Best Practices

Migrating data from Oracle to Amazon S3 can significantly improve data storage scalability and accessibility, leveraging the benefits of cloud infrastructure.

 Assessing Your Oracle Data

 Begin by assessing your Oracle database to determine the size and complexity of the data you need to migrate. Identify critical data, including tables, schemas, and large objects, and plan the migration accordingly.

 Choosing the Right Tools

 Several tools and services can facilitate the migration from Oracle to S3. AWS offers services like AWS Database Migration Service (DMS) and AWS Schema Conversion Tool (SCT) that can automate much of the process. These tools help convert your Oracle schema to a format compatible with S3 and migrate the data efficiently.

 Data Extraction

 Start by extracting data from your Oracle database. Use SQL queries or Oracle’s export utilities (such as Data Pump) to export data into flat files. Ensure that these files are formatted correctly for ingestion into S3.


 Data Transfer to S3

 Once the data is extracted, use AWS tools like AWS S3 Transfer Acceleration, AWS Direct Connect, or AWS Snowball for large-scale data transfers. These tools ensure secure and efficient data transfer, even for extensive datasets.

 Data Validation and Verification

 After transferring the data to S3, it’s crucial to validate and verify the integrity of the data. Compare the data in S3 with the source data in Oracle to ensure that no data is lost or corrupted during the transfer.

 Setting Up Data Access and Management

 Organize your data in S3 using a logical folder structure to facilitate easy access and management. Implement S3’s lifecycle policies to manage data storage costs by automatically transitioning data to lower-cost storage classes or deleting it when no longer needed.

 Integrating with Other AWS Services

One of the key benefits of storing data in S3 is its seamless integration with other AWS services. You can use AWS Glue for ETL processes, Amazon Athena for querying data, and Amazon Redshift for data warehousing. These integrations allow you to build a robust data analytics infrastructure on AWS.

The Functioning of SQL Server Change Data Capture

Image
The SQL Server Change Data Capture feature was first launched by Microsoft in 2005 and had advanced “after update”, “after insert”, and “after delete” capabilities. However, due to its invasive and complex nature, it did not find much favor with the DBAs. Consequently, another version was launched in 2008 that enabled DBAs to directly capture changes made to historical data. This technology is still in use today. The Functioning of the SQL Server Change Data Capture SQL Server CDC captures insert, update, and delete changes made to the SQL Server. The details are then stored in an easy-to-understand relational format. All information about changes made to a target database like columns and metadata are available in the CDC. These changes are stored in tables that replicate the structure of the columns of the tracked tables at the source. Access to the changed data in tables is strictly controlled.  The ETL (Extract, Transform, and Load) application is the best example of the...

An Overview of the SAP BW Extractor

Image
A SAP BW Extractor, also known simply as the SAP Extractor is an optimized data management tool of SAP. Its main function is to extract SAP data from a source system and move it to a downstream data warehouse or store it in a business intelligence system. The SAP BW Extractor feeds SAP BW applications with data extracted from SAP. Functioning of the SAP BW Extractor The SAP BW Extractor integrates SAP data even if the SAP user is not on the Business Warehouse (BW). Hence, this tool can seamlessly populate the delta queue with changed records of the new delta type.    Before using a SAP BW Extractor, it must be hard-coded to ensure that the application-specific Extractor delivers BI Content of the Business Warehouse. The functioning of the Extractor is fully automated. It can identify both the data that is extracted and the tables where it is stored in a read-only format after the Extractor is named in the Data Source. Additionally, a SAP BW Extractor has master da...
