Creating, updating, deleting, and querying resource definitions dynamically

If dynamic resource definition (DRD) is enabled in your IMS system, you can create, update, delete, and query certain IMS resources online through several type-2 commands. You can also create runtime descriptor definitions to use as templates for creating additional resources.

You can use the following type-2 commands:

You can also create runtime descriptor definitions, which are a set of resource definitions that you can use as templates to create additional resources.

The following IMS resources and resource descriptors can be dynamically defined:

You can use Fast Path routing codes and transactions as soon as they are correctly defined by the CREATE command.

After creating an application program or database by using the CREATE command, you must further define the application program or database, as well as its relationships to other resources, by running the appropriate generation utility, such as the Database Description Generation (DBDGEN) utility or the Program Specification Block Generation (PSBGEN) utility.

You can also create and modify these resources by using the Managing Resources series of ISPF panels which are invoked through the IMS applications menu.
