IBM Db2 for z/OS connection
To access your data in IBM Db2 for z/OS, create a connection asset for it.
Db2 for z/OS is an enterprise data server for IBM Z. It manages core business data across an enterprise and supports key business applications.
IBM Db2 for z/OS version 11 and later
Obtain the certificate file
A certificate file on the Db2 for z/OS server is required to use this connection.These steps must be done on the Db2 for z/OS server: Obtain an IBM Db2 Connect Unlimited Edition license certificate file from 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 z/OS 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 ddcsmvs.msg grant public
db2 connect reset
For information about bind commands, see Binding applications and utilities (Db2 Connect Server).
Run catalog commands
Run the following catalog commands from the Db2 client that is configured to access the Db2 for z/OS server:
db2 catalog tcpip node node_name remote hostname_or_address server port_no_or_service_name
db2 catalog tcpip node db2z123 remote 192.0.2.0 server 446
db2 catalog dcs database local_name as real_db_name
db2 catalog dcs database db2z123 as db2z123
db2 catalog database local_name as alias at node node_name authentication server
db2 catalog database db2z123 as db2z123 at node db2z123 authentication server
Create a connection to Db2 for z/OS
To create the connection asset, you need these connection details:
- Hostname or IP address
- Port number
- Collection ID: The ID of the collections of packages to use
- Location: The unique name of the Db2 location you want to access
- Username and password
- 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 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 > 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 Db2 for z/OS connections in the following workspaces and tools:
- DataStage (DataStage service). See Connecting to a data source in DataStage.
- Decision Optimization (Watson Studio and Watson Machine Learning)
- 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)
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 z/OS connected data asset.
Running SQL statements
To ensure that your SQL statements run correctly, refer to the Db2 for z/OS and SQL concepts for the correct syntax.
