Before you set up ATA, you need to install all the prerequisite software. See "About Unified Inventory and Topology" in Unified Inventory and Topology Deployment Guide for installing the prerequisite software.

From Oracle E-delivery site, download the Common Cloud Native Toolkit (Common CNTK) and create an instance for ATA. See the "Unified Inventory and Topology Toolkit" chapter from Unified Inventory and Topology Deployment Guide for more information.

To set up ATA:

1. Set up Graph DB by following the instructions mentioned in Oracle Database Graph Developer's Guide for Property Graph.
2. Install or upgrade UIM. See "Overview of the UIM Cloud Native Deployment" in UIM Cloud Native Deployment Guide for UIM cloud native deployment or "Unified Inventory Management Installation Overview " in UIM Installation Guide for UIM traditional deployment.
3. Configure the Unified Operations Message Bus microservice. See the "Unified Operations Message Bus" chapter in Unified Inventory and Topology Deployment Guide for more information.
4. Configure the Oracle Access Manager microservice. See the "Common Authentication Service" chapter in Unified Inventory and Topology Deployment Guide for more information.
5. Configure the Active Topology Automator microservice and create an instance. See the "Active Topology Automator Service" chapter in Unified Inventory and Topology Deployment Guide for more information.

   An ATA instance is created and a URL is generated. Use this URL to access the ATA application. Alternatively, you can open the ATA home page from UIM. See "Accessing ATA" for more information.
