Hi i am trying to use DEFINE SCHEMA target_schemaz FROM TABLE in a tbuild script and it is failing with
"Teradata Parallel Transporter Version 14.10.00.01

TPT_INFRA: TPT05004: CLI error 224 in connecting session (function ConnectSession).

MTDP: EM_NOHOST(224): name not in HOSTS file or names database.

TPT_INFRA: TPT04032: Error: Schema generation failed for table 'SONARTEST.EOD_USAGE' in DBS '(null)':
