Editing attributes of a data set

Use the Edit Data Set Attributes wizard to edit the modifiable attributes of one or more existing full-function database data sets or Fast Path DEDB area data sets.

About this task

The data set or area attributes and the attribute values that you can specify are determined by IMS. For the most complete explanation of the attributes, their possible values, and the rules governing their specification see the IMS documentation:

Procedure

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

  1. Open the Edit Data Set Attributes wizard by using one of the following methods:
    • In the Project Explorer view, right-click on the dbname.dbd node of the database and select Edit Data Set Attributes
    • In the IMS DBD editor, right-click the DBD name of the database that you want to edit and click Edit Data Set Attributes.
    The Edit Data Set Attributes wizard opens and displays the attributes of the data set that is defined first in the definition of the database.
  2. Select the data set that you need to modify from the drop-down list. If the database contains multiple data sets, you can change which data set is displayed by selecting a different data set name from the drop-down list. The wizard preserves any changed attribute values as you switch between the data sets.
  3. Add or modify the attribute values by using the appropriate fields of the wizard. Click OK.
  4. To save the changes to your data set attributes, ensure that the database is selected and click File > Save or press Ctrl+S.

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.
