IBM Db2 connection | IBM Cloud Pak for Data as a Service

IBM Db2 connection

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

IBM Db2 is a database that contains relational data.

Supported versions

IBM Db2 10.1 and later

Create a connection to Db2

If you have set up an integrated cloud service, select the service instance to automatically fill in the fields in the connection form. Confirm that all the fields are complete.

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

Database
Hostname or IP address
Username and password
Port
Application name (optional): The name of the application that is currently using the connection. For information, see Client info properties support by the IBM Data Server Driver for JDBC and SQLJ.
Client accounting information (optional): The value of the accounting string from the client information that is specified for the connection. For information, see Client info properties support by the IBM Data Server Driver for JDBC and SQLJ.
Client hostname (optional): The hostname of the machine on which the application that is using the connection is running. For information, see Client info properties support by the IBM Data Server Driver for JDBC and SQLJ.
Client user (optional): The name of the user on whose behalf the application that is using the connection is running. For information, see Client info properties support by the IBM Data Server Driver for JDBC and SQLJ.
SSL certificate (if required by your database server)

Credentials

If you select Shared, enter your username and password for the server.

If you select Personal, you have two choices:

Enter your username and password for the server.
Select platform login credentials.
You can use this option only if the Db2 service is hosted on the instance of Cloud Pak for Data that you are connecting to.

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 connections in the following workspaces and tools:

Projects

Cognos Dashboards (Cognos Dashboard Embedded service)
Data quality rules (IBM Knowledge Catalog)
Data Refinery (Watson Studio or IBM Knowledge Catalog)
DataStage (DataStage service). See Connecting to a data source in DataStage. The IBM Db2 for DataStage connection gives you increased performance and more features such as before and after SQL statements and reject links. However, you cannot use the IBM Db2 for DataStage connection outside of the DataStage service.
Decision Optimization (Watson Studio and Watson Machine Learning)
Metadata enrichment (IBM Knowledge Catalog)
Metadata import (IBM Knowledge Catalog)
Notebooks (Watson Studio). Click Read data on the Code snippets pane to get the connection credentials and load the data into a data structure. See Load data from data source connections.
SPSS Modeler (Watson Studio)

Catalogs

Platform assets catalog
Other catalogs (IBM Knowledge Catalog)

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

Running SQL statements

To ensure that your SQL statements run correctly, refer to the Structured Query Language (SQL) topic in the IBM Db2 product documentation for the correct syntax.
