The stored procedures that change the table-to-map assignments run in SQL command-line tools, such as Teradata Studio or BTEQ. You will need to open these BTEQ or Teradata Studio sessions before changing the maps that tables use:
  • One session for the managing process
  • One session for each of the worker processes
For example, if you want 4 worker sessions, open 1 BTEQ window for the manager and another to create all the worker sessions. You could achieve that like this:
.SET SESSIONS 3
.LOGON machine/user,passwd
.REPEAT 3
Teradata recommends using 3 worker sessions for the Mover procedure.
