IBM Db2 Warehouse connection

IBM Db2 Warehouse connection

To access your data in IBM Db2 Warehouse, create a connection asset for it.

IBM Db2 Warehouse is an analytics data warehouse that gives you a high level of control over your data and applications. You can use the IBM Db2 Warehouse connection to connect to a database in these products:

  • IBM Db2 Warehouse in IBM Cloud
  • IBM Db2 Warehouse on-prem

Create a connection to Db2 Warehouse

To create the connection asset, you need these connection details:

  • Database name
  • Hostname or IP address of the database server
  • Port number
  • API key or Username and password
  • SSL certificate (if required by the database server)

Credentials

For Credentials, you can enter either an API key or a username and password

Authenticating with an API Key

You can use an API key to authenticate to Db2 Warehouse in IBM Cloud.

Db2 Warehouse in IBM Cloud
First add the user ID as an IAM user or as a service ID. For instructions, see the Console user experience section of the Identity and access management (IAM) on IBM Cloud topic.

If users want to authenticate with Db2 Warehouse with an IAM API key, the administrator of the Db2 Warehouse instance can add the IAM users by using the User management console, and then the users can each create an API key for themselves by using the IAM access management console.

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Choose the method for creating a connection based on where you are in the platform
