jdbctemplate.xml reference

FAST Search Server 2010

Published: May 12, 2010

Use a copy of jdbctemplate.xml to configure the settings for the FAST Search database connector.

The FAST Search database connector uses the configuration settings to control content extraction. You can run multiple instances of the database connector at the same time by using different configuration files for each instance.

Customizing jdbctemplate.xml

note Note:

To modify a configuration file, verify that you meet the following minimum requirements: You are a member of the FASTSearchAdministrators local group on the computer where FAST Search Server 2010 for SharePoint is installed.

To extract content from a JDBC database and feed it to a FAST Search Server 2010 for SharePoint installation, first create a copy of the jdbctemplate.xml file. Edit the copy in a text or XML editor of your choice (except Notepad) to include the elements and settings for your environment.

To test your settings, run:

%FASTSEARCH%\bin\JDBCConnector.bat testconnections -f <configuration file>

where <configuration file> is the path and file name of your configuration, and %FASTSEARCH% is the FAST Search Server 2010 for SharePoint installation folder.

To run the connector and feed content to FAST Search Server 2010 for SharePoint, run:

%FASTSEARCH%\bin\JDBConnector.bat start -f <configuration file>

Parameter groups quick reference

The following table contains a list of the parameter groups in jdbctemplate.xml. These groups can appear in any order.

Parameter group Description

Parameter group: Input

Defines the properties of the content sources.

Parameter group: Transformation

Describes which content is transformed into the FAST Search Server 2010 for SharePoint item model, and how it occurs.

Parameter group: FASTSearchSubmit

Describes the communication properties when submitting content to FAST Search Server 2010 for SharePoint.

Parameter group: XMLExport

Specifies the values for exporting to XML formatted file(s).

Parameter group: ChangeDetection

Specifies how to detect changes in the database since the last database feed by using row checksums.

Parameter group: ConnectorExecution

Specifies general values that are used when you run the connector.

Parameter group: General

Specifies the configuration name.

JDBC template file format

XML elements in jdbctemplate.xml begin with < and end with />. The XML is defined in FastConnectorConfig-1.0.dtd.

The basic format is as follows:

<group name=" group_name ">

    <parameter name="parameter_name" type="parameter_type">

        <value>value</value>

    </parameter>

</group>

Parameter names are case-sensitive, types are not. Parameter names and types must be enclosed in quotation marks (" ").

A parameter definition can span multiple lines. Spaces, carriage returns, line feeds, and tab characters are ignored in an element definition.

For example:

<group name="ConnectorExecution">
    <parameter name="QueueSize" type="integer">
         <value>200</value>
    </parameter>
    <parameter name="WorkFolder" type="string">
         <value>../var/jdbcconnector</value>
    </parameter>
</group>
Tip Tip:

For long parameter definitions, position values on separate lines and use indentation to make the file easier to read.

The FastConfig element is a special case and is required. All other elements are contained within the FastConfig element.

Here is a sample snippet from a configuration file:

<!DOCTYPE FastConfig SYSTEM "dtd/FastConnectorConfig-1.0.dtd">
<FastConfig>
    <group name="ConnectorExecution">
       <parameter name="QueueSize" type="integer">
             <value>200</value>
        </parameter>
       <parameter name="WorkFolder" type="string">
             <value>../var/jdbcconnector</value>
       </parameter>
    </group>
</FastConfig>

You can add comments anywhere, delimited by <!-- and -->.

For example:

<!DOCTYPE FastConfig SYSTEM "dtd/FastConnectorConfig-1.0.dtd"><FastConfig>
    <!-- The parameter group ConnectorExecution specifies general values
          used when running a connector. -->
    <group name="ConnectorExecution">
       <parameter name="QueueSize" type="integer">
             <value>200</value>
       </parameter>
       <parameter name="WorkFolder" type="string">
             <value>../var/jdbcconnector</value>
       </parameter>
    </group>
</FastConfig>
