We have some Informatica Mload jobs running daily and weekly
since yesterday we are facing some job fails in production due to the below error
we did not change any thing all of sudden we got this issue.
TPTWR_10562 : [ERROR] Type:(Teradata PT API Error), Error: (UPDATE_OPERATOR: TPT10562: Fatal Error from DBCHQE in determining Logon Mechanism support)
Please share if you have any idea.
I don't know if this will correct your error, but we found that the TPT API will experience issues if it is not uninstalled and reinstalled during a patch. You might want to try uninstalling and reinstalling the API and see if that fixes your issue. I know the documentation says you do not have to uninstall but Teradata did determine that for a specific release (not sure which ones) an uninstall is quite necessary.
Appriciate your reply.
We have eresloved this issue. This is due to there was chage is DNS(Domain Name Server) on network side
this caused fails in teradata connection.
This is not related to Teradatata our server network team cleared it.
