Oracle OLAP - Amazon Relational Database Service

Oracle OLAP

Amazon RDS supports Oracle OLAP through the use of the OLAP option. This option provides On-line Analytical Processing (OLAP) for Oracle DB instances. You can use Oracle OLAP to analyze large amounts of data by creating dimensional objects and cubes in accordance with the OLAP standard. For more information, see the Oracle documentation.

Important

If you use Oracle OLAP, Amazon RDS automatically updates your DB instance to the latest Oracle PSU if there are security vulnerabilities with a Common Vulnerability Scoring System (CVSS) score of 9+ or other announced security vulnerabilities.

Amazon RDS supports Oracle OLAP for the following editions and versions of Oracle:

  • Oracle Enterprise Edition, version 19.0.0.0, all versions

  • Oracle Enterprise Edition, version 18.0.0.0, all versions

  • Oracle Enterprise Edition, version 12.2.0.1, all versions

  • Oracle Enterprise Edition, version 12.1.0.2.v13 or later

Prerequisites for Oracle OLAP

The following are prerequisites for using Oracle OLAP:

  • You must have an Oracle OLAP license from Oracle. For more information, see Licensing Information in the Oracle documentation.

  • Your DB instance must be inside a virtual private cloud (VPC). For more information, see Determining whether you are using the EC2-VPC or EC2-Classic platform.

  • Your DB instance must be of a sufficient instance class. Oracle OLAP isn't supported for the db.t3.micro or db.t3.small DB instance classes. For more information, see DB instance class support for Oracle.

  • Your DB instance must have Auto Minor Version Upgrade enabled. This option enables your DB instance to receive minor DB engine version upgrades automatically when they become available and is required for any options that install the Oracle Java Virtual Machine (JVM). Amazon RDS uses this option to update your DB instance to the latest Oracle Patch Set Update (PSU) or Release Update (RU). For more information, see Modifying an Amazon RDS DB instance.

  • Your DB instance must not have a user named OLAPSYS. If it does, the OLAP option installation fails.

Best practices for Oracle OLAP

The following are best practices for using Oracle OLAP:

Adding the Oracle OLAP option

The following is the general process for adding the OLAP option to a DB instance:

  1. Create a new option group, or copy or modify an existing option group.

  2. Add the option to the option group.

  3. Associate the option group with the DB instance.

If Oracle Java Virtual Machine (JVM) is not installed on the DB instance, there is a brief outage while the OLAP option is added. There is no outage if Oracle Java Virtual Machine (JVM) is already installed on the DB instance. After you add the option, you don't need to restart your DB instance. As soon as the option group is active, Oracle OLAP is available.

To add the OLAP option to a DB instance

  1. Determine the option group that you want to use. You can create a new option group or use an existing option group. If you want to use an existing option group, skip to the next step. Otherwise, create a custom DB option group with the following settings:

    • For Engine, choose the Oracle edition for your DB instance.

    • For Major engine version, choose the version of your DB instance.

    For more information, see Creating an option group.

  2. Add the OLAP option to the option group. For more information about adding options, see Adding an option to an option group.

  3. Apply the option group to a new or existing DB instance:

Using Oracle OLAP

After you enable the Oracle OLAP option, you can begin using it. For a list of features that are supported for Oracle OLAP, see the Oracle documentation.

Removing the Oracle OLAP option

After you drop all objects that use data types provided by the OLAP option, you can remove the option from a DB instance. If Oracle Java Virtual Machine (JVM) is not installed on the DB instance, there is a brief outage while the OLAP option is removed. There is no outage if Oracle Java Virtual Machine (JVM) is already installed on the DB instance. After you remove the OLAP option, you don't need to restart your DB instance.

To drop the OLAP option

  1. Back up your data.

    Warning

    If the instance uses data types that were enabled as part of the option, and if you remove the OLAP option, you can lose data. For more information, see Backing up and restoring an Amazon RDS DB instance.

  2. Check whether any existing objects reference data types or features of the OLAP option.

  3. Drop any objects that reference data types or features of the OLAP option.

  4. Do one of the following:

    • Remove the OLAP option from the option group it belongs to. This change affects all DB instances that use the option group. For more information, see Removing an option from an option group.

    • Modify the DB instance and specify a different option group that doesn't include the OLAP option. This change affects a single DB instance. You can specify the default (empty) option group, or a different custom option group. For more information, see Modifying an Amazon RDS DB instance.
