Implementing Data Masking and Data Subset with IMS Unload File Sources

Back Next

Step 4. Define PowerExchange Data Maps for z/OS Sources and Targets

Create a PowerExchange data map for each IMS unload file source.

Each data map must be available to the source and corresponding target. If a target is on the same z/OS system as the source, you can use the same data map for the source and target. Otherwise, send the data map to both the source and target systems.

Start the PowerExchange Navigator.

On the

Resources

tab in the

Resource Explorer

, click

Add

Data Map

In the

Name

dialog box, enter the following information:

Option	Description
Schema Name	Enter a user-defined schema name. PowerExchange uses this name as the first part of the data map name, as follows: `schema_name`.`data_map_name` The name must consist of alphanumeric characters and begin with a letter. Maximum length is 10 characters.
Data Map Name	Enter a user-defined map name. PowerExchange uses this name as the second part of the data map name, as follows: `schema_name`.`data_map_name` The name must consist of alphanumeric characters and begin with a letter. Maximum length is 10 characters.
Access Method	Select one of the following access methods: DL/1 BATCH . IMS database on z/OS. IMS ODBA . IMS database accessed through a PowerExchange Listener on z/OS.
Import Record Definitions	Select this option to import DBD and copybook metadata into the data map. Clear this option to add only the data map. By default, this option is selected. For IMS sources, accept the default.

In the

Data Map Properties

dialog box for the DL/1 Batch or ODBA access method, enter the IMS SSID, DBD Name, and any additional information that is required for the access method.

Click

, and provide the required information in the dialog boxes to import DBD metadata and then copybook metadata for each segment that is defined in the DBD.

For each data map, click

File > Send to Remote Node

, and complete the

Data Map Remote Node

dialog box to send the data map to the PowerExchange Listener on the source system.

If different Listeners will write to the source and target, also send each data map to the Listener on the target system.

After you define a data map, you can view the hierarchy. On the

Data Map

tab in the

Resource Explorer

, right-click a data map and click
