Global Variables

CUBENAME: the name of the cube. This is an After variable
and it returns a string.

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

Can be used as a standalone component for dynamic cube creation
with a defined dimension list.


The activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User

For more information on the log4j logging levels, see the Apache documentation at


The cube creation process does not create dimensions from scratch,
so the dimensions to be used in the cube must be created

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on
the Modules tab in the Integration perspective
of your studio. For details, see

Scenario: Creating a cube in an existing database

The Job in this scenario creates a new two dimensional cube in the Palo demo database


To replicate this scenario, proceed as follows:

Configuring the tPaloCube component

  1. Drop tPaloCube from the Palette onto the design workspace.

  2. Double-click tPaloCube to open its
    Component view.

  3. In the Host name field, type in the host
    name or the IP address of the host server, localhost
    for this example.

  4. In the Server Port field, type in the
    listening port number of the Palo server. In this scenario, it is

  5. In the Username field and the Password field, type in the authentication
    information. In this example, both of them are

  6. In the Database field, type in the
    database name in which you want to create the cube,
    Biker in this example.

  7. In the Cube field, type in the name you
    want to use for the cube to be created, for example, bikerTalend.

  8. In the Cube type field, select the
    Normal type from the drop-down list for
    the cube to be created, meaning this cube will be normal and default.

  9. In the Action on cube field, select the
    action to be performed. In this scenario, select Create cube.

  10. Under the Dimension list table, click the
    plus button twice to add two rows into the table.

  11. In the Dimension list table, type in the
    name for each newly added row to replace the default row name. In this
    scenario, type in Months for the first row and
    Products for the second. These two dimensions exist
    already in the Biker database where the new cube will be created.

Job execution

Press F6 to run the Job.

A new cube has been created in the Biker database and the two
dimensions are added into this cube.
