Purpose

Allows only local DBC users to log on to the system.

Syntax

ENABLE LOCAL DBC LOGONS

Usage Notes

To use this command, the current logon state must be one of the following:
  • Logons are enabled - The system is quiescent.
  • Logons are disabled - The system is quiescent.
To see the current logon state, use one of the following commands:
  • from DBW: QUERY STATE
  • from a Teradata Command Prompt: pdestate -a

Teradata Database must be running for the change to be applied. A database restart is not required for the new setting to take effect.

New non-DBC users and non-local DBC users cannot log on to the system after the ENABLE LOCAL DBC LOGONS command is executed.

Users, other than the DBC, logged on to the system before the ENABLE LOCAL DBC LOGONS command is executed remain logged on, and their jobs continue to run. All sessions are reconnected if the system is restarted.

The ENABLE LOCAL DBC LOGONS command updates the Start With Logons value in the PDE Control GDO, which is viewable using the Control GDO Editor (ctl) utility. For more information, see Control GDO Editor (ctl).
