This document describes how to install the Search Service software contained in the search-service package. The following topics can be found in this section:
This section details the system requirements for installing and operating the Search Service.
The Search Service was developed using Java and Apache Solr and will run on any platform with a supported Java Runtime Environment (JRE). The software was specifically developed under Java version 1.6 and has only been tested with this version. The following commands test the local Java installation in a UNIX-based environment:
% which java /usr/bin/java % java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
The first command above checks whether the java executable is in the environment's path and the second command reports the version. If Java is not installed or the version is not at least 1.6, Java will need to be downloaded and installed in the current environment. Consult the local system administrator for installation of this software. For the do-it-yourself crowd, the Java software can be downloaded from the Oracle Java Download page. The software package of choice is the Java Standard Edition (SE) 6, either the JDK or the JRE package. The JDK package is not necessary to run the software but could be useful if development and compilation of Java software will also occur in the current environment.
The Registry Service requires a Java application server for hosting the web application. The suggested application server for this release is Apache Tomcat with a minimal version of 6.0.20 through version 7.0.X. Consult the local system administrator for installation of this software. For the do-it-yourself crowd, the Apache Tomcat software can be downloaded from the Apache Tomcat page. Choose the version to download (6.0 or 7.0) from the menu on the left.
Download the search-service package from the PDS FTP site. The binary distribution is available in identical zip or tar/gzip packages. The installation directory may vary from environment to environment but in UNIX-based environments it is typical to install software packages in the /usr/local directory and in Windows-based environments it is typical to install software packages in the C:\Program Files directory. Unpack the selected binary distribution file with one of the following commands:
% unzip search-service-1.1.1-bin.zip or % tar -xzvf search-service-1.1.1-bin.tar.gz
Note: Depending on the platform, the native version of tar may produce an error when attempting to unpack the distribution file because many of the file paths are greater than 100 characters. If available, the GNU version of tar will resolve this problem. If that is not available or cannot be installed, the zipped package will work just fine in a UNIX environment.
The commands above result in the creation of the search-service-1.1.1 directory with the following directory structure:

The Search Service includes the configuration for Solr as well as the Java extensions written to support the PDS Search Protocol and PDAP Handler. In order to deploy Solr with the Search Service configuration, please complete the following procedure:
ln -s /usr/local/search-service /usr/local/search-service-1.1.1
<?xml version="1.0" encoding="utf-8" ?> <Context docBase="/usr/local/search-service/solr.war" debug="0" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/usr/local/search-service" override="true" /> <Parameter name="javax.xml.transform.TransformerFactory" type="java.lang.String" value="net.sf.saxon.TransformerFactoryImpl" override="true"/> <Loader className="org.apache.catalina.loader.VirtualWebappLoader" virtualClasspath="/usr/local/search-service/lib/saxon-9.jar"/> </Context>
CATALINA_OPTS="${CATALINA_OPTS} -Dsolr.pds.home=/usr/local/search-service"
rm /usr/local/search-service ln -s /usr/local/search-service /usr/local/search-service-${project-version}
This error means the application failed to install correctly. The following are potential mitigation strategies:
