  1. Migrating Data to Amazon S3 from Oracle with AWS DMS

  2. Amazon S3 (Simple Storage Service) offers unlimited cost-effective storage service and is at the heart of data lakes in AWS (Amazon Web Service). Amazon RDS (Relational Database Service) for Oracle databases is a popular source for data lakes. • For AWS DMS Oracle to S3migration, certain conditions have to be fulfilled. You must have an AWS account, an Amazon RDS for Oracle database, and the S3 bucket should be in the same region where the AWS DMS replication instance is created for the migration process.

  3. Next, for implementing the AWS DMS Oracle to S3process, the following steps have to be taken. · An AWS Identity and Access Management (IAM) role has to be created to get to the target S3 bucket. · The source Amazon RDS for Oracle database for replication has to be prepared. · AWS DMS instance and endpoints have to be created · A full load task has to be created · A CDC (Change Data Capture) task has to be created. It is essential to use Amazon RDS for Oracle as the source both in the same Region and the target S3 bucket.

  4. Migrating database Oracle to S3 with AWS DMS • There are two systems for AWS DMS Oracle to S3and the one chosen by an organization depends on its specific needs. · Importing data, Oracle Data Pump, and Database Link – Here, the Oracle Data Pump along with the Oracle DBMS_FILE_TRANSFER package are used to connect to a source Oracle instance. It can either be through an Amazon RDS for Oracle database instance or an Amazon EC2 instance. The Oracle data is exported to a dump file with the DBMS_DATAPUMP package. This file is then copied to the Amazon RDS Oracle DB instance through a connected database link. Lastly, the data is imported to S3 through the DBMS_DATAPUMP package. · Importing Data, Oracle Data Pump, and Amazon S3 Bucket – The Oracle source data is exported using the Oracle DBMS_DATAPUMP package and the file is dumped in an Amazon S3 bucket. This file is downloaded to the DATA_PUMP_DIR directory in the RDS Oracle DB instance. Finally, the data in the dump file is imported and copied to the Amazon RDS Oracle DB instance using the DBMS_DATAPUMP package.

  5. The purpose of AWS DMS Oracle to S3is to ensure that oracle databases can be optimized on Amazon S3. There are two ways to do so. • The first is to shift the on-premises database Oracle to Amazon RDS which is the most popular managed database service for the most-used platforms including Oracle. The complexities of database management in Oracle are reduced considerably when it is running on the Amazon infrastructure. • The next is to run EC2 compute instances and Elastic Block Store (EBS) storage in on-premises Oracle databases. However, when this is done the entire infrastructure of servers and storage has to be replaced with that of AWS.
