Use the Enterprise Data Manager (EDM) to import metadata for each z/OS data source.
To launch the Enterprise Data Manager, log in to Data Archive and select
Accelerators > Enterprise Data Manager
.
To create an application version for the data source, right-click
Custom Apps Only
in the navigator pane, select
New Application Version
, and enter an application name and description.
To import PowerExchange metadata for the application version that you created, complete the following tasks:
Highlight the object and click
File > Import Metadata from Database
. The
Connect to Import Metadata from Database
dialog box appears.
If you defined a connection, select it and enter your z/OS user name and password.
If you are defining a conection, enter the data source name and the z/OS user name and password.
The
Database Mining
wizard appears.
Select the schema and list of tables for the data source.
At the prompt to mine child tables of the selected tables, click
No
.
Because the PowerExchange NRDB2 access method does not support foreign key relationships, you cannot mine child tables. By clicking
No
, you ensure that the PowerExchange Listener on z/OS does not spawn multiple subtasks that would return empty result sets. If you enabled the ILMBRIDGE or NOFKEYS Compatibility option for the PowerExchange ODBC connection, the PowerExchange Listener does not spawn multiple empty subtasks, regardless of what you select for this option.
