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

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.
  1. Start the PowerExchange Navigator.
  2. On the
    Resources
    tab in the
    Resource Explorer
    , click
    Add
    Data Map
    .
  3. 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.
  4. 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.
  5. Click
    Next
    , 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.
  6. 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
Display IMS Hierarchy
.
The IMS hierarchy for the IMS data map appears. The following image shows an example IMS hierarchy:
This diagram displays the IMS hierarchy.
