IBM Db2 on Cloud connection

IBM Db2 on Cloud connection

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

Db2 on Cloud is an SQL database that is managed by IBM Cloud and is provisioned for you in the cloud.

Create a connection to Db2 on Cloud

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

  • Database name
  • Hostname or IP address
  • Port number
  • Username and password

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

In a project
Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.
In a catalog
Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space
Click Add to space > Connection. See Adding connections to a deployment space.
In the Platform assets catalog
