VTAM Considerations › Runtime Considerations

Runtime Considerations

If VTAM fails or is taken down during DC/UCF system execution, you do not have to take the system down. To resume processing, the VTAM ACB must be closed, then reopened after VTAM has been restarted.

The following example illustrates the above procedure:

• The VTAM line XYZ is varied offline after failure with the following command:

  DCMT VARY LINE XYZ OFFLINE
  

• VTAM is started up (if not done previously).
• The VTAM line XYZ is varied online with the following command:

  DCMT VARY LINE XYZ ONLINE
  

DCMT commands are described in the CA IDMS System Tasks and Operator Commands Guide.
