Loading Data into Autonomous Database on Dedicated Exadata Infrastructure

You can bulk load data into Autonomous Database on Dedicated Exadata Infrastructure using Oracle Database tools, and Oracle or other 3rd party data integration tools.

Data loading usually refers to loading sample data into Autonomous Database to explore its features or develop proof-of-concept applications.

Data loading is different from data migration. Data migration usually involves large volumes of data and can be a one-time activity or routine activity depending on the requirement. See Migrating Data into Autonomous Database to explore the different data migration options supported by Autonomous Database.

Data Loading Overview

In general you load data from files local to your client computer or from files stored in a cloud-based object store.

For the fastest data loading experience Oracle recommends uploading the source files to a cloud-based object store, such as Oracle Cloud Infrastructure Object Storage, before loading the data into your Autonomous Database. Oracle provides support for loading files that are located locally in your data center, but when using this method of data loading you should factor in the transmission speeds across the Internet which may be significantly slower.

The figure below shows the most common utilities that you can use for loading data into Autonomous Database. You can also see the different file formats and storage options supported by the data loading options.

The table below lists the various data loading tools and utilities for your reference.
Tool/Utility Description Autonomous Database on Public Cloud Autonomous Database on Exadata Cloud@Customer Applicable Use Cases For More Details
DBMS_CLOUD Package

The PL/SQL package DBMS_CLOUD provides support for loading data from files in the cloud to tables created in an Autonomous Database.

You can load data from different file formats using the DBMS_CLOUD.COPY_DATA and the DBMS_CLOUD.COPY_TEXT procedures.

External Network File System (NFS) devices provided by the customer or OCI File System Service (FSS) may be attached using the DBMS_CLOUD_ADMIN procedures.

Applicable Applicable Huge datasets leveraging cloud object store for fast loading.

 Load Data Using SQL*Loader
SQL Developer

Graphical version of SQL*Plus that gives database developers a convenient way to perform basic tasks.

This tool lets you connect to schemas for MySQL and selected third-party (non-Oracle) databases, such as Microsoft SQL Server, Sybase Adaptive Server, and IBM DB2, and view metadata and data in these databases.

You can then move these databases to Autonomous Database using PL/SQL subprograms.
