IBM Db2 for i connection

IBM Db2 for i connection

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

Db2 for i is the relational database manager that is fully integrated on your system. Because it is integrated on the system, Db2 for i is easy to use and manage.

Supported versions

IBM DB2 for i 7.2+


Obtain the certificate file

A certificate file on the Db2 for i server is required to use this connection. To obtain an IBM Db2 Connect Unlimited Edition license certificate file, go to IBM Db2 Connect: Pricing and Installing the IBM Data Server Driver for JDBC and SQLJ. For installation instructions, see Activating the license certificate file for Db2 Connect Unlimited Edition.

Run the bind command

Run the following commands from the Db2 client that is configured to access the Db2 for i server.
You need to run the bind command only once per remote database per Db2 client version.

db2 connect to DBALIAS user USERID using PASSWORD
db2 bind [email protected] blocking all sqlerror continue messages ddcs400.msg grant public
db2 connect reset

For information about bind commands, see Binding applications and utilities.

Run catalog commands

Run the following catalog commands from the Db2 client that is configured to access the Db2 for i server:

  1. db2 catalog tcpip node node_name remote hostname_or_address server port_no_or_service_name

    db2 catalog tcpip node db2i123 remote server 446

  2.  db2 catalog dcs database local_name as real_db_name

    db2 catalog dcs database db2i123 as db2i123

  3. db2 catalog database local_name as alias at node node_name authentication server

    db2 catalog database db2i123 as db2i123 at node db2i123 authentication server

For information about catalog commands, see CATALOG TCPIP NODE and CATALOG DCS DATABASE.

Create a connection to Db2 for i

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

  • Hostname or IP address
  • Port number
  • Location: The unique name of the Db2 location you want to access
  • Username and password
  • SSL certificate (if required by the database server)

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 > Connect to a data source. 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 Import assets > Data access > Connection. See Adding data assets 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 Db2 for i connections in the following workspaces and tools:



  • Platform assets catalog

  • Other catalogs (IBM Knowledge Catalog)

Watson Query service
You can connect to this data source from Watson Query.


For SPSS Modeler, you can use this connection only to import data. You cannot export data to this connection or to a Db2 for i connection connected data asset.
