tPaloDimensionList Standard properties

These properties are used to configure tPaloDimensionList running in the Standard Job framework.

The Standard
tPaloDimensionList component belongs to the Business Intelligence family.

The component in this framework is available in all Talend
products.

Basic settings

Use an existing connection	Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined. Note that when a Job contains the parent Job and the child Job, Component List presents only the connection components in the same Job level.
Host Name	Enter the host name or the IP address of the host server.
Server Port	Type in the listening port number of the Palo server.
Username and Password	Enter the Palo user authentication data. 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.
Database	The name of the database where the dimensions of interest reside.
Retrieve cube dimensions	Select this check box to retrieve dimension information from an existing cube.
Cube Note: Available when you select the Retrieve cube dimensions check box.	Type in the name of the cube from which dimension information is retrieved.
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. 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.
	Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.
	Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see Talend Studio User Guide.

Advanced settings

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

Global Variables

Global Variables	DIMENSIONNAME: the name of the dimension. This is a Flow 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 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.

Retrieving detailed dimension information from a given database

The Job in this scenario retrieves details of all of the dimensions from a given
database.

To replicate this scenario, proceed as follows:

Setting up the Job

Drop tPaloDimensionList and tLogRow from the component Palette onto the design workspace.
Right-click tPaloDimensionList to open
the contextual menu.
From this menu, select Row > Main to link the two components.

Configuring the tPaloDimensionList component

Double-click the tPaloDimensionList
component to open its Component
view.
In the Host name field, type in the host
name or the IP address of the host server, localhost
for this example.
In the Server Port field, type in the
listening port number of the Palo server. In this scenario, it is
7777.
In the Username field and the Password field, type in the authentication
information. In this example, both of them are
admin.
In the Database field, type in the
database name where the dimensions of interest reside,
Biker in this example.

Job execution

Press F6 to run the Job.

Details of all the dimensions in the Biker database are
retrieved and listed in the console of the Run
view.

For further information about the output schema, see Discovering the read-only output schema of tPaloDimensionList.
