Configuring Teradata Database Accounts

On this Page

This account is used by the Snaps in the Teradata Snap Pack.

You can create an account from Designer or Manager. In Designer, when working on pipelines, every Snap that needs an account prompts you to create a new account or use an existing account. The accounts can be created in or used from:

  • Your private project folder: This folder contains the pipelines that will use the account.
  • Your Project Space’s shared folder: This folder is accessible to all the users that belong to the Project Space.
  • The global shared folder: This folder is accessible to all the users within an organization in the SnapLogic instance.


Account Configuration

In Manager, you can navigate to the required folder and create an account in it (see Accounts). To create an account for Teradata: 

  1. Click Create, then select Teradata > Teradata Database Account/Teradata Database Dynamic Account
  2. Supply an account label.
  3. Supply the account properties for your database. 
  4. (Optional) Supply additional information on this account in the Notes field of the Info tab.
  5. Click Apply.

Avoid changing account credentials while pipelines using them are in progress. This may lead to unexpected results, including locking the account.

Account Types

Teradata Database Account

 Account Settings


Label


Required. User provided label for the account instance

Account properties


Required. Enter in the information to create a connection to the database.

Hostname


Required. The server's address to connect to.

Default value: [None] 

Port Number

The database server's port to connect to.

Port can be specified but it often results in the address being parsed as an IPv6 address. Care should be taken.

Default value: [None] 

Database name


Required. The database name to connect to.

Default value: [None] 

Username


Username that is allowed to connect to the database. Username will be used as the default username when retrieving connections. The username must be valid in order to set up the data source.

Default value: [None] 

Password


Password used to connect to the data source. Password wil be used as the default password when retrieving connections. The password must be valid in order to set up the data source.

Default value: [None] 

JDBC jars


List of JDBC JAR files to be loaded. A different driver binary for a driver must have a different name, the same name can not be reused for a different driver. If this property is left blank, a default JDBC driver will be loaded.

Default value: [None] 

JDBC Driver Class


Required. JBDC driver class name to use.

Default value: com.teradata.jdbc.TeraDriver 

Advanced properties

Auto commit


When selected, each of the batches is committed immediately after it is executed. If the Snap fails, only the batch being executed at that moment is rolled back.

When deselected, the Snap execution output is committed only after all the batches are executed. If the Snap fails, the entire transaction is rolled back, unless the Snap finds invalid input data before it sends the insert request to the server, and routes the error documents to the Error view.

Default value: Selected

Batch size


Required. Number of statements to execute at a time.
Note: Select queries are not batched.

Using a large batch size could use up the JDBC placeholder limit of 2100.

Default value: 50 

Fetch size


Required. Number of rows to fetch at a time when executing a query.

Large values could cause the server to run out of memory.

Default value: 100 

Max pool size


Required. Maximum number of connections a pool will maintain at a time.

Default value: 50 

Max life time


Required. Maximum lifetime of a connection in the pool. Ensure that the value you enter is a few seconds shorter than any database or infrastructure-imposed connection time limit. A value of 0 indicates an infinite lifetime, subject to the Idle Timeout value. An in-use connection is never retired. Connections are removed only after they are closed.

Default value: 30

Idle Timeout

Required. The maximum amount of time a connection is allowed to sit idle in the pool. A value of 0 indicates that idle connections are never removed from the pool.

Default value: 5

Checkout timeout


Required. Number of milliseconds to wait for a connection to be available when the pool is exhausted. Zero waits forever. An exception will be thrown after the wait time has expired.

Default value: 10000

Hostname


Required. The server's address to connect to.

Account Encryption

Standard Encryption

If you are using Standard Encryption, the High sensitivity settings under Enhanced Encryption are followed.


Enhanced Encryption

If you have the Enhanced Account Encryption feature, the following describes which fields are encrypted for each sensitivity level selected per each account.

Account:

  • High: Password
  • Medium + High: Password
  • Low + Medium + High: Password

Example

For the pipeline, define the pipeline parameters:

  • Host
  • Username
  • Password
  • Database

Use the values to supply values them in the Dynamic Account.

Back in the Teradata Export to HDFS pipeline, create a Teradata Database Dynamic Account 

  • Set the expression toggle on for the Hostname, Database name, Username and Password
  • Supply the pipeline parameter values manually into the toggled properties
  • Click Apply and fill the Snap Settings for the desired function.

You cannot Validate an account connection when creating a Teradata Database Dynamic Account because the account properties of a dynamic account are provided dynamically as pipeline parameters.

4.24 Patch

424patches8799 Latest
  • Enhanced the Teradata Execute Snap by adding a new field, Advanced options, which extends support with microsecond precision for TIMESTAMP data type.
  • Fixed an issue in the TPT Load Snap where the Snap failed to load data into the table while creating an output.
  • Fixed an issue with the TPT Load Snap wherein now a null value is loaded as null and empty string is loaded as empty string.

    • This fix may cause existing pipelines to fail if empty string values are expected to be loaded as null.

    • Following are the new configurations:

      • VARCHAR QuotedData= Optional

      • VARCHAR OpenQuoteMark= \”

      • VARCHAR NullColumns= Yes

4.24main8556
Stable

Enhanced the Teradata Select Snap to return only the selected output fields or columns in the output schema (second output view) using the Fetch Output Fields In Schema check box. If the Output Fields field is empty all the columns are visible.

4.23main7430
 
Stable

Fixes the multi-line value issue and issue in the TPT Load Snap where the Snap writes null for both an empty string and null values in the input data. The fix for this issue was to add the following three lines in the script and wrap all the values in double quotes unless they are null while writing the input data into a temp CSV file. 
VARCHAR QuotedData = 'Optional',
VARCHAR OpenQuoteMark = '\"'
VARCHAR NullColumns = 'Yes'

This fix may cause existing pipelines to fail if empty string values are expected to be loaded as null.

Fixed the following issues with DB Snaps:

  • The connection thread waits indefinitely causing the subsequent connection requests to become unresponsive.
  • Connection leaks occur during Pipeline execution.
