Editing attributes of an IMS record segment

Use the Edit Segment Attributes wizard to edit the modifiable attributes of an existing IMS database.

About this task

The segment attributes and the attribute values that you can specify are determined by IMS. For the most complete explanation of the attributes and their possible values, see SEGM statements (IMS System Utilities).

Procedure

To edit the modifiable attributes of a segment complete the following steps.

  1. Open the Edit Segment Attributes wizard by using one of the following methods:
    • In the Project Explorer view, right-click on the segment name and select Edit Segment Attributes
    • In the IMS DBD editor, right-click on the segment that you want to edit and click Edit Segment Attributes.
    The Edit Segment Attributes wizard opens and displays the attributes of the segment that you can modify along with the name, external name, and the name of the parent segment.
  2. Add or modify the attribute values by using the appropriate fields of the wizard. Click OK.
  3. To save the changes to your segment, ensure that the database is selected and click File > Save or press Ctrl+S. The changes are saved as macro instructions for the IMS DBD Generation utility.

What to do next

If your IMS system supports IMS-managed ACBs and DDL, you can submit your updated definitions as DDL statements directly to IMS. The DDL is generated automatically by IMS Explorer. For more information, see Submitting DBD definitions to IMS systems that support DDL.

To use the updated definitions with the IMS generation utilities, you must export the DBD generation utility macro instruction statements to IMS and follow the IMS process for changing resources by using the generation utilities. To export the macro instructions to IMS, see Exporting IMS resources to z/OS.
