In the case of restart, Teradata ARC uses the SESSIONS parameter that is specified the first time the utility is run. Do not change the input file between the initial execution and restart.
Specify NORESTART to disable the RESTART parameter.
The RESTART runtime parameter only applies to Mainframe systems (z/OS). Restart of Teradata ARC is no longer supported on network-attached systems.
