  1. Transferring Data from Oracle Database to Amazon S3 Amazon S3 or Simple Storage Service is fundamentally an object storage service offering stringent data security, availability, and performance. Though these features are near similar to those of conventional databases like Oracle, S3 is not a suitable option for a database. Instead, the common use of S3 is to store backed-up data and to transfer data from one database to another. When transferring databases, the target database has to be one that is hosted by Amazon such as RSD

  2. Migrating data from Oracle to S3transfers data from on-premise to the cloud.

  3. There are primarily two methods for this: Importing Data - Oracle Data Pump and Amazon S3 Bucket In this method, data from the source Oracle database has to be exported using the Oracle DBMS_DATAPUMP package and then dumping the file in an Amazon S3 bucket. The dump file is then downloaded from the Amazon S3 bucket to the DATA_PUMP_DIR directory on the RDS Oracle DB instance. Finally, the data is imported from the dump file and copied into the Amazon RDS Oracle DB instance using the DBMS_DATAPUMP package.

  4. Importing Data – Oracle Data Pump and a Database Link This method uses the Oracle Data Pump and the Oracle DBMS_FILE_TRANSFER package. The process links to a source Oracle instance and this is either an Amazon EC2 instance or an Amazon RDS for Oracle DB instance. Data is then exported through the DBMS_DATAPUMP package. Next, the dump file from the Oracle instance is copied to the Amazon RDS Oracle DB instance which is connected using a database link. Finally, the data is imported from using the DBMS_DATAPUMP package. It is always preferable to transfer data from Oracle to S3.
