Two types of restarts exist:

  • Automatic
  • User-initiated
  • Automatic Restarts

    When a software or hardware failure occurs, the Teradata Database system automatically attempts to bring itself back up into an operational state. This type of restart results in an automatic execution of a Teradata Database system-recovery operation. As part of the restart processing, the Teradata Database system saves the error codes that were generated, reloads Teradata Database system software, and enables logons.

    User-Initiated Restarts

    Manual restarts are activated by the user. Users can initiate a restart from any of the hardware switches or by one of the following methods:

  • Issue the RESTART command. For information on the RESTART command, see Chapter 33: “Vproc Manager (vprocmanager).”
  • At the system command line, type the following command:
  • tpareset comment-string

    where comment-string briefly describes the reason for the restart.
