To change the configuration for data extraction, click Extract Properties tab.

In the canvas, the Extract Type drop-down displays the default extraction type JDBC.

  • The extract properties can be set one time in the Admin module based on the company standards. Refer the page Editing Extract Properties for more details.
  • The changes made to the properties in the data point automatically reflect to all the objects connected to this data point.
  • Any extract properties that have been overridden in the dependent objects will not be affected by this change.
  • During the execution of the job, the load command properties are defined automatically based on the values provided for the extract properties.

Based on the requirements, you can do the following:

  • Change the default Property values, then a button appears beside the changed value and to revert click Reset to Default button.
  • To rest all the values and set to accommodate general industry standards and data formats, click Reset All to Default link.
Note: To view specific property details, you can enter the keyword in the search bar, and the particular property details are displayed.

Extraction type: JDBC

Property

Description

Default value

Other possible values

Extraction Mode

The extraction mode can either be File or Pipe.

Pipe option is used to stream the data directly from Source to Target.

When File option is used then the data extracted from source is staged on the agent server before loading into the target.

File 

Pipe

File Type

Defines the format of extracted data. (Only delimited text format is supported)

Delimiter 


Column Delimiter

Specifies the delimiter on the extracted file data.

ASCII 01 (SOH)

Any ASCII character

Compression

Use this option to specify if the data needs to be compressed before transfer from source agent to Target load agent.

NO 

YES

Compression Type (Displays only when Compression is "Yes")

On choosing a compression format, the user is required to give the corresponding compression codec and compression type (Only default Compression Type is supported).

gzip 


Encryption

Use this option to specify if the data needs to be encrypted before transfer from source agent to Target load agent.

This option is also used when the target is file system and the generated file is required to be encrypted. This encryption is not dependent on source and target systems using same or different agent.

To set up encryption keys, refer Setting up encryption keys at Agents.

NO 

YES

Encryption Type (Displays only when Encryption is "Yes")

When encryption is enabled then, user needs to specify the encryption algorithm to be used.

AES can be used for symmetric key encryption. Choose from 128, 192 and 256 bit key sizes.

PGP encryption can be used for asymmetric key encryption.

AES-128

AES-192

AES-256

PGP

Cipher Operation Mode (Displays only when Encryption is "Yes" and Encryption Type is "AES")

Specify the mode of operation, you can either use CBC (default mode) or GCM. In CBC mode, each block of plaintext is dependent on previous ciphertext block before being encrypted i.e block processing and where as in GCM its parallel processing and independent.

CBCGCM

Encrypted AES SecreteKey (Displays only when Encryption type is "AES")

Specify if the AES key is generated by using secret key or not.

NO 

YES

Text Qualifier

Specify if the text columns in the source data needs to be enclosed in quotes.

Empty

Single

Double

Escape Character

The character immediately following the escape character is escaped.

This needs to be specified if the text qualifier is provided and the text qualifier character can appear in the source data.

Empty

\\ (Recommended)

Any ASCII character

Date StyleSpecifies how to interpret the date format

YMD 

MDY,DMY,DMONY,MONDY,Y2MD, MDY2, DMY2, DMONY2 and MONDY2

Date Delimiter

Specifies the separator used in the date format. (Only default delimiter is supported)


Time Style

Specifies the format of the time portion in the data.

24 HOUR 

12 HOUR

Time Delimiter

Specifies the character used as separate the time components. (Only default delimiter is supported)


Decimal Delimiter

Specify the decimal delimiter for float/double/numeric data types.

EMPTY

Note: JDBC is default extraction type and the default values are set by the Administrator in Admin | Configurations | Extraction Properties.
