Hi Teradata Experts,
I'm new to Teradata. I'm basically an Oracle DB Architect. I got a nice opportunity to work on one of an existing Teradata DW Application in our Organization.
I would like to ask a question.
In Oracle, when a user wants to establish a session with the Server, the Oracle Listener will receive the request and push that request to any one of the Oracle Instance either based on Round Robin/Based on the Instances Work Load. From there on, the Instance handles the session and if something happens to that Instance and it crashed, the session will be moved to another instance and that is transparent to the user.
In Teradata i see each and every node has some PE and AMPS and Each AMP manages its own data and data is not shared between other AMPS.
When a user tries to establish a connection to Teradata, will Teradata Gateway receive and send that request to any 1 NODE?(if yes, on what basis)
Thanks
Prakash
