Tell and Logoff - Call-Level Interface Version 2

Tell and Logoff

After calling DBCHINI, set the delay options as follows.

Delay Option	Setting
Wait‑during‑delay	N
Tell‑if‑delay	Y

Given this combination of options, a delay can be handled as follows:

The application calls DBCHCL for some function

The delay occurs before or after receiving information from DBCHCL

CLIv2 returns control to the application, with a return code of 286

The application takes action appropriate to the application

Before submitting a request, save a copy of the request in case it must be resubmitted. If a transaction spans several requests, save a copy of each request in the transaction in case the transaction must be resubmitted.

CLIv2 logs the session off when it encounters the delay. CLIv2 sends the logoff request to the Teradata Database when communication is re-established.
