How to activate if software-only changes are allowed

The following procedure describes how to activate a configuration dynamically if only software changes are allowed. Refer to z/OS HCD Planningz/OS HCD Planning on information when both hardware and software configuration changes are allowed and when only software configuration changes are allowed.

1. On the Primary Task Selection panel, select Activate or process configuration data, and from the resulting panel select Activate configuration dynamically. HCD displays the following panel:

   *------------------- Activate Software Configuration Only -----------------*
   |                                                                           |
   | Specify or revise the values for IODF activation.                         |
   |                                                                           |
   |                                                                           |
   | Hardware changes will be validated, and the activation will be rejected   |
   | in the case of an error.                                                  |
   |                                                                           |

   |                                                                           |
   *--------------------------------------------------------------------------*

   The panel contains information about the currently active IODF.
2. On the Activate Software Configuration Only panel, you can change the fields that relate to the IODF that is to be activated. It is recommended that you first test an activation before you actually dynamically activate a configuration.
3. If the dynamic activation completed successfully, HCD displays a message.

If dynamic activation fails

If the activation is rejected, HCD displays a panel that lists the message(s) and reasons for a failure. From the displayed message list, you can request further information. The message list can also be displayed by using the command SHOWMSG ACTIVATE on any panel that has a command line (except on help panels).
