How to Get Started With Autonomous Data Warehouse
Our previous post Data Warehouse 101: Introduction outlined the benefits of the Autonomous Data Warehouse–it’s simple, fast, elastic, secure, and best of all it’s incredibly easy to spin up an environment and start a new project. If you read through the last post, you already know how to sign up for a data warehouse trial account and download SQL Developer and Data Visualization Desktop, both of which come free with the Autonomous Data Warehouse.
This post will focus on the steps to get started using the Oracle Autonomous Data Warehouse. We will provision a new Autonomous Data Warehouse instance and connect to the database using Oracle SQL Developer.
How to Use Autonomous Data Warehouse with Oracle Cloud Infrastructure
STEP 1: Sign in to Oracle Cloud
Go to cloud.oracle.com. Click Sign In to sign in with your Oracle Cloud account.
Enter your Cloud Account Name and click My Services.
Enter your Oracle Cloud username and password, and click Sign In.
STEP 2: Create an Autonomous Data Warehouse Instance
Once you are logged in, you are taken to the cloud services dashboard where you can see all the services available to you. Click Create Instance.
Note: You may also access your Autonomous Data Warehouse service via the pull out menu on the top left of the page, or by using Customize Dashboard to add the service to your dashboard.
Click Create on the Autonomous Data Warehouse tile. If it does not appear in your Featured Services, click on All Services and find it there.
Select the root compartment, or another compartment of your choice where you will create your new Autonomous Data Warehouse instance. If you want to create a new Compartment or learn more, click here.
Note – Avoid the use of the ManagedCompartmentforPaaS compartment as this is an Oracle default used for Oracle Platform Services.
Click on Create Autonomous Data Warehouse button to start the instance creation process.
This will bring up the Create Autonomous Data Warehouse screen where you will specify the configurations of the instance. Select the root compartment, or another compartment of your choice.
Specify a memorable display name for the instance. Also specify your database's name, for this lab use ADWFINANCE.
Next, select the number of CPUs and storage size. Here, we use 4 CPUs and 1 TB of storage.
Then, specify an ADMIN password for the instance, and a confirmation of it. Make a note of this password.
For this lab, we will select Subscribe To A New Database License. If your organization owns Oracle Database licenses already, you may bring those license to your cloud service.
Make sure everything is filled out correctly, then proceed to click on Create Autonomous Data Warehouse.
Your instance will begin provisioning. Once the state goes from Provisioning to Available, click on your display name to see its details.
You now have created your first Autonomous Data Warehouse instance. Have a look at your instance's details here including its name, database version, CPU count and storage size.
Because Autonomous Data Warehouse only accepts secure connections to the database, you need to download a wallet file containing your credentials first. The wallet can be downloaded either from the instance's details page, or from the Autonomous Data Warehouse service console.
STEP 4: Download the Connection Wallet
In your database's instance details page, click DB Connection.
Under Download a Connection Wallet, click Download.
Specify a password of your choice for the wallet. You will need this password when connecting to the database via SQL Developer later, and is also used as the JKS keystore password for JDBC applications that use JKS for security. Click Download to download the wallet file to your client machine.
Note: If you are prevented from downloading your Connection Wallet, it may be due to your browser's pop-blocker. Please disable it or create an exception for Oracle Cloud domains.
Connecting to the database using SQL Developer
Start SQL Developer and create a connection for your database using the default administrator account 'ADMIN' by following these steps.
STEP 5: Connect to the database using SQL Developer
Click the New Connection icon in the Connections toolbox on the top left of the SQL Developer homepage.
Fill in the connection details as below:
Connection Name: admin_high
Password: The password you specified during provisioning your instance
Connection Type: Cloud Wallet
Configuration File: Enter the full path for the wallet file you downloaded before, or click the Browse button to point to the location of the file.
Service: There are 3 pre-configured database services for each database. Pick <databasename>_high for this lab. For
example, if you the database you created was named adwfinance, select adwfinance_high as the service.
Note : SQL Developer versions prior to 18.3 ask for a Keystore Password. Here, you would enter the password you specified when downloading the wallet from ADW.
Test your connection by clicking the Test button, if it succeeds save your connection information by clicking Save, then connect to your database by clicking the Connect button. An entry for the new connection appears under Connections.
If you are behind a VPN or Firewall and this Test fails, make sure you have SQL Developer 18.3 or higher. This version and above will allow you to select the "Use HTTP Proxy Host" option for a Cloud Wallet type connection. While creating your new ADW connection here, provide your proxy's Host and Port. If you are unsure where to find this, you may look at your computer's connection settings or contact your Network Administrator.

NOTE: The display name for the Autonomous Data Warehouse is ADW Finance Mart and the Database name is ADWFINANCE. This is for representation only and you can choose your name.
In the next post, Data Warehouse 101: Setting up Object Store, we will start exploring a data set, how to load and analyze the data set.
