When the value for Tell-if-delay is not appropriate for the application, perform the following procedure before calling DBCHCL.
- Set Change-options to 'Y'.
- Change the value for Tell-if-delay as follows.
If CLIv2 is to... Then change the value for Tell-if-delay to... inform the application of a delay Y not inform the application of a delay N
If a restart occurs during a logoff request, CLIv2 reconnects the session and resubmits the logoff request.
Use mnemonics for the codes. Mnemonics are provided in the language definition file for the DBCAREA.
The Tell-if-delay and Wait-during-delay DBCAREA options interact as described in the following table.
Wait-during-delayWait-during-delay | |||
---|---|---|---|
N | Y | ||
Tell-if-delay | N | Invalid | The application is not informed of the delay and waits for the delay to end. |
Tell-if-delay | Y | For delays due to loss of communication with or a database restart, the application is informed that Tell-if-delay was honored with a final return code 286, and the session will be logged off when the database becomes available (the request may or may not have executed). For delays by Teradata Workload Management, the application receives a response indicating the request was not executed rather than be delayed. | The application is informed that Tell-if-delay was honored with a preliminary return code 286, and subsequently receives the response when the delay ends and the request is executed. |
