- Specify the log_directory parameter first
- Use the NPLOGDIR environment variable to specify the log directory
where the following is true:
|block_size=n||Block size, in bytes, of the data transfer operation where acceptable Range of n is 1 byte-16 MB.
The default, if you do not specify the block_size parameter, is 1,048,576 bytes.
Due to the limitations in the Data Connector, the block size must be greater than or equal to the size of the largest record passing through the pipe. When the module is used in a trickle feed environment, as with TPump, the shortest latency occurs when the block size is set to the maximum record size.
|confirm_fallback_deletion=y||Specification to make the Teradata Access Module for Named Pipes present a confirmation prompt before deleting the fallback data file.|
|fallback_directory=directorypath||Path of the fallback data file directory. The default directory, if you do not specify the fallback_directory parameter, is as follows:
|fallback_file=filename||Name of the fallback data file.|
|log_directory=directorypath||Path of the log file directory. If you do not specify the log_directory parameter, the default is:
|log_level=n||Specification that sets the level of detail to be posted to the log file, where the following is true:
|need_full_block=no||Enables buffer flushing within client scripts when set to “no.”
Must be set to “no” when TPump is using the latency option with IMPORT.
Buffer flushing performs check-point restarting differently when not enabled (the default), the fallback recovery data generated is different, and is not interchangeable between flushing and non-flushing modes.
|pipe_wait=n||Holds the sleep interval (in milliseconds) for polling the pipe when need_full_block=no. By default, the pipe_wait is set to 10 milliseconds.|
|signature_check=checklevel||Specification that sets the level of detail to be posted to the log file, where the following is true:
|[no_fallback||[With this parameter presented in the Initialization string, Teradata Access Module for Named Pipes will not create the Fallback file. Also, no checkpoints will be done for the Teradata Access Module for Named Pipes, the utility job couldn't be restart-able. Also, when this parameter is presented, the fallback_file and fallback_directory setting will be ignored.|
