Overview

Alation Cloud Service Applies to Alation Cloud Service instances of Alation

Customer Managed Applies to customer-managed instances of Alation

Core Connector Core connectors are included with all Alation platform tiers (subject to each tier’s connector limits) and are fully supported by Alation.

Overview

You can install and upgrade the connector using one of the following methods, depending on your Alation deployment type:

  • On-premise instances: Download the latest connector package from the Alation Customer Portal (Customer Portal > Connectors), then upload and install it in Alation.

  • Alation Cloud Service: Install and upgrade the connector directly from your instance without downloading the package. Any connector available on the Alation Customer Portal (Customer Portal > Connectors) can be installed and upgraded this way. See Install Connectors (Cloud-Native Architecture). You can also download the connector package from the Alation Customer Portal and install or upgrade it manually by uploading the Zip file.

Use this connector to catalog self-managed SQL Server deployments. It supports on-premises deployments and SQL Server instances running on customer-managed virtual machines, such as Azure VMs or Amazon EC2. For Azure SQL Database and Azure SQL Managed Instance, we recommend using the Azure SQL DB OCF Connector. The SQL Server OCF connector catalogs SQL Server objects such as tables, columns, views, primary keys, foreign keys, functions, and function definitions. It enables end-users to search and find SQL Server objects from the Alation user interface.

Use the instructions given in this guide to install and manage the connector.
