IBM Informix connection

IBM Informix connection

To access your data in an IBM Informix database, create a connection asset for it.

IBM Informix is a database that contains relational, object-relational, or dimensional data. You can use the Informix connection to access data from an on-prem Informix database server or from IBM Informix on Cloud.

Supported Informix versions (on-prem)

  • Informix 14.10 and later. This version does not support the Progress DataDirect JDBC driver, which is used by the Informix connection. The Informix connection supports Informix 14.10 features that are comparable to previous Informix versions, but not the new features. Issues related to DataDirect's JDBC driver are not supported.
  • Informix 12.10 and later
  • Informix 11.0 and later
  • Informix 10.0 and later
  • Informix 9.2 and later

Create a connection to Informix

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

  • Name of the database server
  • Name of the database
  • Hostname or IP address of the database
  • Port number (Default is 1526)
  • Username and password

On-prem Informix database servers: 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
Click New connection. See Adding platform connections.

Next step: Add data assets from the connection

Where you can use this connection

You can use Informix connections in the following workspaces and tools:



  • Platform assets catalog

  • Other catalogs (IBM Knowledge Catalog)
