To access data in a z/OS® file, you must define a connection that specifies the data source
name for the Classic federation server, as well as the data set, user
name, and user password.
Before you begin
Complete these prerequisite tasks:
- Verify that the z/OS File
stage is configured properly.
- Create a job that reads or writes data by adding the z/OS File stage and Complex Flat File stage
to it and creating any required links.
- Verify that the user name that connects to the Classic federation
data server has DBADM authority.
Procedure
- Double-click the z/OS File stage icon to open the stage properties.
- In the Data source name field, enter
the ODBC data source name for the Classic federation driver. On UNIX and Linux, use the name of the data source that
you specified in the DATASOURCE parameter in
the file that is named in the CAC_CONFIG environment variable. On Microsoft Windows, use the name of the data source
that you created by using the Microsoft ODBC Data Source Administrator.
- In the User name field, enter the
name of the user who has authorization to access the z/OS files that you want to read from or write
to. On UNIX and Linux, if you do not enter a user
name, the value of the USERID parameter in the
file that is named in the CAC_CONFIG environment variable is used.
- In the User password field, enter
the password that is used to log into the Classic federation data
server. On UNIX and Linux, if you do not enter a password,
the value of the USERPASSWORD parameter in the
file that is named in the CAC_CONFIG environment variable is used.
- In the Dataset name field, enter
a fully qualified valid data set name.
- If you are defining a connection for a job that reads a z/OS file, you might need to complete
these additional optional fields:
- Volume(s) – Enter a list of one or
more volume names, separated by commas. Specify a volume name if the z/OS data set is not cataloged.
- Allocation type – Choose Shared (default) to specify that the file can be shared
with other jobs, or choose Exclusive to specify
that the file is for use only by this job.
- Missing file – Choose what to do if
the file specified in the Dataset name field
cannot be found. Choose Error (default), and
the job terminates with an error. Choose OK, and the job runs but treats the missing file as an empty file.
