After calling DBCHINI, set the delay options as follows.

 

Delay Option

Setting

Wait‑during‑delay

Y

Tell‑if‑delay

N

Given this combination, the steps if a delay occurs are as follows:

  • The application calls DBCHCL for some function
  • The delay occurs before or after receiving information from DBCHCL
  • The application is not notified of the delay and does not gain control
  • Communication is re-established
  • The application regains control from CLIv2 with a return code of zero
  • When the application calls DBCHCL for the Fetch function, it obtains the following:
  • The Teradata Database does not know anything about a request with that request number (Error parcel with error code 2825)
  • The Teradata Database aborted that request (Failure parcel with failure code 2828)
  • The request completed successfully but the response has been lost (Error parcel with error code 2826)
  • The application takes action appropriate to the application
  • Note: 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.)

    Note: If Wait For Response is set to N, CLIv2 logs the session off when it encounters the delay. CLIv2 sends the logoff request to the Teradata Database when communication is re-established.
