Preparing for Installation¶
To ensure a rapid and successful installation, your team will need to prepare by gathering key information from internal resources and performing pre-configuration setup tasks.
Examples include procuring a system on which you will install Alation, gathering information on database versions, creating service accounts with the right permissions, and completing the necessary setup for Alation to ingest query logs from your source systems.
For the system you provide, you will need:
System sizing requirements and specifications
Understanding of your network environment
User authentication requirements in your environment
Database Connection Preparation¶
For each Database make sure you have:
Connectivity Verified: Appropriate ports opened on the firewall between Alation and your database servers
Confirmed Version support for all components
Confirmed Authentication Type support for all components
Service Account created
Permissions to run Metadata Extraction
Permissions to run Sampling and Profiling
Query log setup specific to each DB (see Adding Data Sources)
BI Tool and Other System Connection Preparation¶
For each BI Tool or other system, confirm the following:
Service accounts with appropriate permissions
If you are going to use any OCF Connectors
Alation Analytics V2¶
Alation Analytics V2 is a solution which provides a way for Alation Administrators to monitor the usage of the Alation Catalog. Alation Analytics V2 can be installed on a remote host - separately from the Alation Catalog, which is recommended by Alation. For more details, refer to Alation Analytics V2.
Open Connector Framework¶

Open Connector Framework is a solution which provides a way to support external connectors. From release 2020.4, Alation supports OCF for BI sources with a number of out-of-the-box BI connectors. From 2021.3, Alation supports OCF for RDBMS sources and offers a number of out of the box RDBMS connectors. It is recommended to install the OCF components on the same server with the Alation application. For more details, refer to Open Connector Framework.
