Chapter 3: <strong>Teradata</strong> T<strong>Pump</strong> Commands<br />
BEGIN LOAD<br />
Syntax Element<br />
frequency<br />
DATAENCRYPTION<br />
ON/OFF<br />
Description<br />
The interval in minutes between check pointing operations. Specify an<br />
unsigned integer from 0 through 60, inclusive.<br />
To specify a CHECKPOINT frequency of less than or equal to 60, a<br />
checkpoint is recorded at the specified frequency, in minutes.<br />
To specify a CHECKPOINT frequency of more than 60, <strong>Teradata</strong> T<strong>Pump</strong><br />
terminates the job.<br />
Specifying a CHECKPOINT frequency of zero bypasses all checkpoint<br />
functions. <strong>Teradata</strong> T<strong>Pump</strong> does not do checkpoint operations at all,<br />
which is different from <strong>Teradata</strong> Tools and Utilities 07.00 and earlier.<br />
The <strong>Teradata</strong> T<strong>Pump</strong> job will not be re-startable once data loading has<br />
begun.<br />
If a CHECKPOINT frequency is not specified, check pointing occurs<br />
every 15 minutes by default.<br />
Whether specified or not, checkpoints are written at the end of each<br />
data input source.<br />
Note: Checkpoints should not be set for an FDL-compatible INMOD<br />
routine with the FOR, FROM, or THRU options. When an<br />
FDL-compatible INMOD routine is used with the FOR, FROM, or<br />
THRU options, <strong>Teradata</strong> T<strong>Pump</strong> terminates and an error message<br />
appears if the checkpoint frequency is other than zero.<br />
Keyword to encrypt import data and the request text during the<br />
communication between <strong>Teradata</strong> T<strong>Pump</strong> and <strong>Teradata</strong> <strong>Data</strong>base.<br />
If ON, the encryption will be performed. If DATAENCRYPTION is not<br />
specified, the default is OFF.<br />
The "-y" runtime parameter applies the encryption to all connected<br />
sessions, which include the control session and the load sessions. This<br />
option only applies the encryption to the load sessions, which are the<br />
sessions specified by the SESSIONS keyword in the BEGIN LOAD<br />
command, and overrides the "-y" runtime parameter when OFF is<br />
explicitly specified. For example, assuming the PARTITION command<br />
is not used in the job, when "-y" runtime parameter is specified with the<br />
job and DATAENCRYPTION OFF is specified in the script, the<br />
encryption will only apply to the control session. Similarly, assuming<br />
the PARTITION command is not used in the job when "-y" runtime<br />
parameter is not specified with the job, and DATAENCRYPTION ON is<br />
specified in the script, the encryption will apply to all load sessions but<br />
not the control session.<br />
When the PARTITION command is used, the encryption setting<br />
explicitly specified in the PARTITION command will override the<br />
setting of this option over the sessions defined by the PARTITION<br />
command.<br />
