tSPSSStructure – Docs for ESB 5.x

Component family

Business Intelligence

Function

tSPSSStructure retrieves information about the
variables inside .sav files.

Purpose

tSPSSStructure addresses variables inside .sav
files. You can use this component in combination with tFileList to gather information about existing *.sav files to further
analyze or check the findings.

Basic settings

Schema and Edit Schema

A schema is a row description. It defines the number of fields to be processed and passed on
to the next component. The schema is either Built-In or
stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

The schema metadata in this component is predefined and thus read-only. It is
based on the internal SPSS convention. You can click Edit
schema to view the predefined metadata.

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.

Filename

Name or path of the .sav file to be processed.

Advanced settings

tStatCatcher Statistics

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

Global Variables

NB_LINE: the number of rows read by an input component or
transferred to an output component. 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

Use this component as a start component. It needs an output flow.

Log4j

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

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

Limitation

Oracle provides two kinds of JVM platforms (32-bit and 64-bit). By default, the
JVM used in a 64-bit operating system is the 64-bit version of the JVM. Since the
JSPSS.dll file used by this component is compiled in the 32-bit JVM, it is needed to
configure the 32-bit JVM for Job execution in Talend Studio
installed on a 64-bit operating system.

To do so, perform the following:
