tTeradataTPTExec Standard properties

Property Type

Either Built-In or Repository.

Built-In: No property data stored centrally.

Repository: Select the repository file in which the properties are stored. The database connection related fields that follow are completed automatically using the data retrieved.

Execution platform

Select the Operating System that will be used to run the Job, either Windows or Unix.

TDPID

Specify the Teradata director program identifier. It can be either the name or the IP address of the Teradata database system being accessed.

Database name

Specify the name of the Teradata database.

Username and Password

Specify the username and the password for the Teradata database authentication.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Built-In: You create and store the schema locally for this component only.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Consumer Operator

Select a consumer operator from the drop-down list.

• Load: writes data into an empty Teradata table using the Teradata FastLoad utility protocol.

• Inserter: inserts data into Teradata tables with SQL sessions.

• Update: performs Insert, Update, or Delete operations using the Teradata MultiLoad utility protocol.

• Stream: loads data continuously into Teradata tables using the Teradata TPump utility.

For more information about Teradata consumer operators, see Teradata consumer operators.

Action On Data

This list field appears only when the Update or Stream operator is selected from the Consumer Operator drop-down list.

Producer Operator

Select a producer operator from the drop-down list. Currently, only the DataConnector operator is supported.

DataConnector: accesses files either directly or through an access module, and then writes it to the data stream.

For more information about Teradata producer operators, see Teradata producer operators.

Table

Specify the name of the table to be written into the Teradata database. Note that only one table can be written at a time.

Script generated folder

Specify the directory under which the Teradata Parallel Transporter script file will be created during the Job execution. This script file will be deleted at the end of the Job execution.

Load file

Specify the file holding the data to be loaded into the Teradata database.

Error file

Specify the file in which log messages will be recorded.

Make sure that the path to the file exists and is accessible to TPT tools.

Custom script

Field separator

Character, string or regular expression to separate fields.

Define Log table

Select this check box to specify a log table so that log messages recorded in the log file will also be written into the log table.

This option is available when Inserter is not selected from the Consumer Operator drop-down list in the Basic settings view.

Set Script Parameters

Select this check box to define script parameters, which will be used when generating a script during the Job execution. If you do not specify them manually, the system will use their default values.

This field is not available when Custom script is selected.

Enforce database name on Log, Work, and Error tables

Select this option to use a database other than the default database for the work table, log table, and the error table.

With this option selected, provide the new database name for the work table, log table, and the error table in the Option attributes table under the Apply TPT consumer operator optional attributes option.

This option is available when Inserter is not selected from the Consumer Operator drop-down list in the Basic settings view.

Load Operator

Specify the load operator.

This field appears only when the Set Script Parameters check box is selected.

Data Connector

Specify the data connector.

This field appears only when the Set Script Parameters check box is selected.

Job Name

Specify the name of a Teradata Parallel Transporter Job which is defined using the Teradata tbuild command.

For further information about the tbuild command, see tbuild.

This field appears only when the Set Script Parameters check box is selected.

Layout Name (schema)

Specify a schema for the data to be loaded.

This field appears only when the Set Script Parameters check box is selected.

Return mload error

Select this check box to specify the exit code number to indicate the point at which an error message should display in the console.

Character set encoding of the script

This check box is selected by default, allowing you to specify the encoding to be used in the Teradata TPT script.

Character set encoding of the data

This field is not available when Custom script is selected.

Apply TPT consumer operator optional attributes

Select this check box to define optional attribute(s) for the consumer operator that you have selected.

For more information about optional attributes of each consumer operator, see Teradata Parallel Transporter Reference.

Optional attributes

Click the [+] button below the table to add as many rows as needed, each row for an optional attribute, and set the following two parameters for each attribute:

• Name: click the cell and select an optional attribute from the drop-down list. The list of optional attributes may vary depending on the consumer operator you have selected. For details about supported optional attributes for each consumer operator, see Supported optional attributes for each consumer operator.

• Value: enter the value for the corresponding optional attribute.

For more information about the attribute value definition, see Teradata Parallel Transporter Reference.

This table appears only when the Apply TPT consumer operator optional attributes check box is selected.

tStatCatcher Statistics

Select this check box to collect the log data at the component level.

Global Variables

EXIT_VALUE: the process exit code. This is an After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage rule

Used as a single-component Job or subJob, this component offers high performance in inserting data from an existing file to a table in the Teradata database. For further information about the usage of this component, see tbuild.

Limitation

The Teradata client tool with the Teradata Parallel Transporter Base and Teradata Parallel Transporter Stream features needs to be installed on the machine where Jobs using this component are executed.
