Editing attributes of an IMS database

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

About this task

The database 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 DBD statements (IMS System Utilities).

Procedure

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

  1. Open the Edit Database 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 Database Attributes
    • In the IMS DBD editor, right-click the DBD name of the database that you want to edit and click Edit Database Attributes.
    The Edit Database Attributes wizard opens and displays the attributes of the database that you can modify along with the name and access method of the database.
  2. Add or modify the attribute values by using the appropriate fields of the wizard. Click OK.
  3. To save the changes to your DBD, 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.
