Creating an Oracle DB instance and connecting to a database on an Oracle DB instance - Amazon Relational Database Service

Creating an Oracle DB instance and connecting to a database on an Oracle DB instance

The basic building block of Amazon RDS is the DB instance. Your Amazon RDS DB instance is similar to your on-premises Oracle database.

Important

Before you can create or connect to a DB instance, make sure to complete the tasks in Setting up for Amazon RDS.

There's no charge for creating an AWS account. However, by completing this tutorial, you might incur costs for the AWS resources that you use. You can delete these resources after you complete the tutorial if they are no longer needed.

In this topic, you create a sample Oracle DB instance and connect to it. Finally, you delete the sample DB instance.

Creating a sample Oracle DB instance

The DB instance is where you run your Oracle databases.

Note

RDS for Oracle supports a single-tenant architecture, where a pluggable database (PDB) resides in a multitenant container database (CDB). For more information, see RDS for Oracle architecture.

You can use Easy create to create a DB instance running Oracle with the AWS Management Console. With Easy create, you specify only the DB engine type, DB instance size, and DB instance identifier. Easy create uses the default settings for the other configuration options. When you use Standard create instead of Easy create, you specify more configuration options when you create a database, including ones for availability, security, backups, and maintenance.

In this example, you use Easy create to create a DB instance running the Oracle database engine with a db.m4.large DB instance class.

For information about creating DB instances with Standard create, see Creating an Amazon RDS DB instance. If you want to use free tier, use Standard create.

To create an Oracle DB instance with Easy create enabled

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the upper-right corner of the Amazon RDS console, choose the AWS Region in which you want to create the DB instance.

  3. In the navigation pane, choose Databases.

  4. Choose Create database and ensure that Easy create is chosen.

    
						Easy create option
  5. In Configuration, choose Oracle.

  6. For DB instance size, choose Free tier. If Free tier isn't available, choose Dev/Test.

  7. For DB instance identifier, enter a name for the DB instance, or leave the default name of database-1.

  8. For Master username, enter a name for the master user, or leave the default name.

    The Create database page should look similar to the following image.

    
						Create database page
  9. To use an automatically generated master password for the DB instance, make sure that the Auto generate a password box is selected.

    To enter your master password, clear the Auto generate a password box, and then enter the same password in Master password and Confirm password.

  10. (Optional) Open View default settings for Easy create.

    
						Display Easy create settings for Oracle DB

    You can examine the default settings used with Easy create. The Editable after database is created column shows which options you can change after database creation.

    • To change settings with No in that column, use Standard create.

    • To change settings with Yes in that column, either use Standard create, or modify the DB instance after it is created to change the settings.

    The following are important considerations for changing the default settings:

    • In some cases, you might want your DB instance to use a specific virtual private cloud (VPC) based on the Amazon VPC service. Or you might require a specific subnet group or security group. If so, use Standard create to specify these resources. You might have created these resources when you set up for Amazon RDS. For more information, see Provide access to your DB instance in your VPC by creating a security group.

    • If you want to be able to access the DB instance from a client outside of its VPC, use Standard create to set Public access to Yes.

      If the DB instance should be private, leave Public access set to No.

    • If you want to use free tier, use Standard create to set the Oracle version lower than version 12.2, and then choose Free tier in Templates.

  11. Choose Create database.

    If you used an automatically generated password, the View credential details button appears on the Databases page.

    To view the master user name and password for the DB instance, choose View credential details.

    
						Master user credentials after automatic password generation

    To connect to the DB instance as the master user, use the user name and password that appear.

    Important

    You can't view the master user password again. If you don't record it, you might have to change it.

    If you need to change the master user password after the DB instance is available, you can modify the DB instance to do so. For more information about modifying a DB instance, see Modifying an Amazon RDS DB instance.

  12. For Databases, choose the name of the new Oracle DB instance.

    On the RDS console, the details for new DB instance appear. The DB instance has a status of Creating until the DB instance is ready to use. When the state changes to Available, you can connect to the DB instance. Depending on the DB instance class and the amount of storage, it can take up to 20 minutes before the new instance is available.

Connecting to your sample Oracle DB instance

After Amazon RDS provisions your DB instance, you can use any standard SQL client application to connect to the DB instance. In this procedure, you connect to your sample DB instance by using the Oracle sqlplus command line utility. To download a standalone version of this utility, see SQL*Plus User's Guide and Reference.

To connect to a DB instance using SQL*Plus

  1. Make sure your DB instance is associated with a security group that provides access to it. For more information, see Provide access to your DB instance in your VPC by creating a security group.

    If you didn't specify the appropriate security group when you created the DB instance, you can modify the DB instance to change its security group. For more information, see Modifying an Amazon RDS DB instance.

  2. Find the endpoint (DNS name) and port number for your DB instance.

    1. Open the RDS console and then choose Databases to display a list of your DB instances.

    2. Choose the Oracle DB instance name to display its details.

    3. On the Connectivity & security tab, copy the following pieces of information:

      • Endpoint

      • Port

      You need both the endpoint and the port number to connect to the DB instance.

      
								My DB instances list
    4. On the Configuration tab, copy the following pieces of information:

      • DB name (not the DB instance ID)

      • Master user name

      You need both the DB name and the master user name to connect to the DB instance.

  3. Enter the following command on one line at a command prompt to connect to your DB instance by using the sqlplus utility. Use the following values:

    • For dbuser, enter the name of the master user that you copied in the preceding steps.

    • For HOST=endpoint, enter the endpoint that you copied in the preceding steps.

    • For PORT=portnum, enter the port number that you copied in the preceding steps.

    • For SID=DB_NAME, enter the Oracle database name (not the instance name) that you copied in the preceding steps.

    sqlplus 'dbuser@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=endpoint)(PORT=portnum))(CONNECT_DATA=(SID=DB_NAME)))'

    You should see output similar to the following.

    SQL*Plus: Release 11.1.0.7.0 - Production on Wed May 25 15:13:59 2011 SQL>

For more information about connecting to an Oracle DB instance, see Connecting to your Oracle DB instance. For information on connection issues, see Can't connect to Amazon RDS DB instance.

Deleting your sample DB instance

After you are done exploring the sample DB instance that you created, you should delete the DB instance so that you are no longer charged for it.

To delete a DB instance with no final DB snapshot

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the navigation pane, choose Databases.

  3. Choose the DB instance that you want to delete.

  4. For Actions, choose Delete.

  5. For Create final snapshot?, choose No, and choose the acknowledgment.

  6. Choose Delete.
