Multiload Plugin - Parallel or Sequential execution mode?
Posted: Thu Jul 13, 2006 12:52 pm
Hello Forum,
Can Teradata Multiload Plugin run in Parallel execution mode?
I don't think it can, although I've heard rumors that it can.
I believe this because of the following:
1. Nothing in the Plugin documentation seems to suggest that any parallel execution functionality. Then again, the plugin documentation doesn't look like it was updated since 7.5 Server.
2. Nothing on the Stage suggests any changed interface since server edition, except for the advanced tab, which sets default execution to sequential.
3. Executing this module by selecting execution mode of parallel causes errors during execution. The errors seem to be caused by several processes to attempt to lock the Teradata Report File and Teradata Control File, resulting in an abort.
4. There does not seem to be any mechanism to control distinct ER table, UV table, WT table, LOG table, a distinct named pipe, control file, or report file.
Can anybody confirm whether parallel execution mode can work?
Your free wisdom is appreciated.
