deployment.xml reference

FAST Search Server 2010

Published: May 12, 2010

Use the deployment.xml file to outline the topology of your Microsoft FAST Search Server 2010 for SharePoint installation. The file describes all the servers in your FAST Search Server 2010 for SharePoint deployment and the distribution of services. Single server installations have a default deployment.xml file which may be modified.

This section specifies the deployment.xml file format. This file contains detailed structure information that specifies how FAST Search Server 2010 for SharePoint is distributed over multiple servers. One or more services will run on each node in the FAST Search Server 2010 for SharePoint application.

You can find example deployment.xml templates under <FASTSearchFolder>\etc\, where <FASTSearchFolder> is the path of the folder where you have installed FAST Search Server 2010 for SharePoint, for example C:\FASTSearch.

The purpose of deployment.xml is to enable central control over FAST Search Server 2010 for SharePoint servers and services in an installation. You can reconfigure FAST Search Server 2010 for SharePoint by adding or removing servers or services in the deployment.xml file. See Reconfigure the farm deployment (FAST Search Server 2010 for SharePoint).

The deployment.xml file must be created and modified on the FAST Search Server 2010 for SharePoint administration server only.

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.

Element quick reference

The following table lists the elements in deployment.xml. These elements can appear in any order.

Element Description

<deployment>

Top level element describing the complete installation

<instanceid>

The unique name of the FAST Search Server 2010 for SharePoint instance. Used by SCOM.

<connector-databaseconnectionstring>

The JDBC URL used by indexing connectors for configuration data. Used by the FAST Search database connector and the FAST Search Lotus Notes connector.

<host>

Each server in the FAST Search Server 2010 for SharePoint deployment is defined within the host tag. Each host (server) holds a set of elements determining the components that will run on the server.

<searchcluster>

Defines the multiple server configuration for query matching and indexer nodes (search cluster). Describes which parts of the installation will serve queries and perform indexing. It also specifies if fault tolerance is enabled.

<admin>

Part of the host element. Specifies if a host (server) will have the administration component.

<document-processor>

Part of the host element. Specifies if a host (server) will have item processing components.

<content-distributor>

Part of the host element. Specifies if a host (server) will have the content distributor component.

<indexing-dispatcher>

Part of the host element. Specifies if a host (server) will have the indexing dispatcher component.

<crawler>

Part of the host element. Specifies if a host (server) will have a Web crawler component.

<webanalyzer>

Part of the host element. Specifies if a host (server) will have a Web analyzer component.

<searchengine>

Part of the host element. Specifies if a host (server) will have a search cluster component (indexing or query matching or both).

<query>

Part of the host element. Specifies if a host (server) will have the query processing component.

<row>

Part of the searchcluster element. Specifies the features of a single search row or indexer row in the search cluster (deployment).

How it works

The post-setup configuration wizard uses the deployment.xml file to configure the local server. On the administration server, the wizard retrieves a local copy, and on non-administration servers, the wizard gets a copy from the administration server.

Information in deployment.xml is used to generate the local configuration files that are needed to configure the instance of FAST Search Server 2010 for SharePoint.

The local configuration files are updated during post-setup configuration and when you call the cmdlet Set-FastSearchConfiguration.

deployment.xml file format

The deployment.xml file uses XML syntax. The XML schema section contains a formal specification of the file syntax.

The basic element format is as follows:

<element_name [attribute_name="value"] [attribute_name="value"] ... />

For example:

<document-processor processes="4" />

Elements and attributes are case-sensitive. Attribute values must be enclosed in quotation marks (" ") and are not case-sensitive.

Comments can be added anywhere and are delimited by <!-- and -->.

For example:

<!-- Add a useful comment here-->
