Oracle Cloud Graph on ADW

This architecture uses Oracle Autonomous Data Warehouse and creates a database user with the necessary permissions to perform graph operations. The architecture also includes Graph Studio Notebooks for easy graph data preparation and visualization.

The repository contains the Terraform code to create a Resource Manager stack, that creates all the required resources and configures the created resources to add a graph user and the required BANK_ACCOUNTS and BANK_TXNS tables.

Prerequisites

• Permission to manage the following types of resources in your Oracle Cloud Infrastructure tenancy: autonomous-database-family, orm-family, virtual-network-family, network-security-groups, bastion, bastion-session and instance-family,.
• Permission to use the following types of resources in your Oracle Cloud Infrastructure tenancy: tag-namespaces.
• Quota to create one Autonomous Database on Shared Infrastructure instance with at least 1 OCPU and 1 Tb storage.

Components

Component	Description
Autonomous Data Warehouse	Platform for management and analysis of graph data
Identity Policy	Statements to grant the user access to the ADW and tags

Deployment Instructions

Deploy Using Oracle Resource Manager

1. Click Deploy to Oracle Cloud. If you aren't already signed in, when prompted, enter the tenancy and user credentials.
2. Review and accept the terms and conditions
3. Select the region where you want to deploy the stack.
4. Follow the on-screen prompts and instructions to create the stack.
5. Wait for the job to be completed, and review the plan. To make any changes, return to the Stack Details page, click Edit Stack, and make the required changes. Then, run the Plan action again.
6. If no further changes are necessary, return to the Stack Details page, click Terraform Actions, and select Apply.

Local Development

1. Perform pre-deployment setup described here.

2. Clone the Module with the following commands to make a local copy fo the repo:

   git clone https://github.com/oracle-quickstart/oci-arch-graph.git
   cd oci-arch-graph/
   ls

3. To deploy directly with the terraform CLI, rename terraform.tfvars.template to terraform.tfvars and set all the variables. Run terraform init and then terraform apply.

   Note, the instructions below are to build a .zip file from your local copy for use in ORM. If you do not want to use ORM and instead deploy with the terraform CLI, then you need to rename provider.tf.cli -> provider.tf. This is because authentication works slightly differently in ORM vs the CLI. This file is ignored by the build process below. Make sure you have terraform v1.0+ cli installed and accessible from your terminal.

4. In order to build the zip file with the latest changes you made to this code, you can simply go to build-orm folder and use terraform to generate a new zip file:

   On the first run you are required to initialize the terraform modules used by the template with terraform init command:

   terraform init

5. Once terraform is initialized, run terraform apply to generate ORM zip file:

   terraform apply
   data.archive_file.generate_zip: Refreshing state...
   Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

   This command will package the content of terraform folder into a zip and will store it in the build-orm\dist folder. You can check the content of the file by running unzip -l dist/orm-graph-stack.zip

6. Login to Oracle Cloud Infrastructure to import the stack

   Home > Developer Services > Resource Manager > Stacks > Create Stack

7. Upload the orm-graph-stack.zip and provide a name and description for the stack

8. Configure the Stack. The UI will present the variables to the user dynamically, based on their selections.

9. Click Next and Review the configuration.

10. Click Create button to confirm and create your ORM Stack.

11. On Stack Details page, you can now run Terraform commands to manage your infrastructure. You typically start with a plan then run apply to create and make changes to the infrastructure. More details below:

    TERRAFORM ACTIONS	DESCRIPTION
    Plan	terraform plan is used to create an execution plan. This command is a convenient way to check the execution plan prior to make any changes to the infrastructure resources.
    Apply	terraform apply is used to apply the changes required to reach the desired state of the configuration described by the template.
    Destroy	terraform destroy is used to destroy the Terraform-managed infrastructure.
