+<h1>Installers Guide<a class="headerlink" href="#installers-guide" title="Permalink to this headline">¶</a></h1>
+<p id="introduction"><strong>Introduction</strong></p>
+<p>This is our &#8220;new and improved&#8221; installation guide, it was first
+released with the Dataverse Network application versions 2.2.4, when we
+introduced the new, automated and much simplified installation process.
+As of February 2012, it has been updated to reflect the changes made in
+the newly released version 3.0 of the software. (Our existing users will
+notice however, that the changes in the installation process have been
+fairly minimal).</p>
+<p>The guide is intended for anyone who needs to install the DVN app,
+developers and Dataverse Network administrators alike.</p>
+<p>The top-down organization of the chapters and sections is that of
+increasing complexity. First a very basic, simple installation scenario
+is presented. The instructions are straightforward and only the required
+components are discussed. This use case will in fact be sufficient for
+most DVN developers and many Dataverse Network administrators. Chances
+are you are one of such users, so if brave by nature, you may stop
+reading this section and go straight to the <a class="reference internal" href="#quick-install"><em>“Quick Install”</em></a>   chapter.</p>
+<p>The “basic” installation process described in the first chapter is
+fully automated, everything is performed by a single interactive script.
+This process has its limitations. It will likely work only on the
+supported platforms. Optional components need to be configured  outside
+of the Installer (these are described in the &#8220;Optional Components&#8221;
+section).</p>
+<p>For an advanced user, we provide the detailed explanations of all the
+steps performed by the Installer. This way he or she can experiment with
+individual configuration options, having maximum flexibility and control
+over the process. Yet we tried to organize the advanced information in
+such a way that those who only need the most basic instructions would
+not have to read through it unnecessarily.  Instead we provide them with
+an easy way to get a bare-bones configuration of the DVN up and running.</p>
+<p>If you are interested in practicing a DVN installation in a Vagrant
+environment you can later throw away, please follow the instructions at
+<a class="reference external" href="https://github.com/dvn/dvn-install-demo">https://github.com/dvn/dvn-install-demo</a> to spin up a Linux virtual
+machine on your laptop with <tt class="docutils literal"><span class="pre">vagrant</span> <span class="pre">up</span></tt>. When you are finished with
+this temporary DVN installation, you can delete the virtual machine with
+<tt class="docutils literal"><span class="pre">vagrant</span> <span class="pre">destroy</span></tt>.</p>
+<p>If you encounter any problems during installation, please contact the
+development team
+at <a class="reference external" href="mailto:support&#37;&#52;&#48;thedata&#46;org">support<span>&#64;</span>thedata<span>&#46;</span>org</a>
+or our <a class="reference external" href="https://groups.google.com/forum/?fromgroups#!forum/dataverse-community">Dataverse Users
+Community</a>.</p>
+<div class="section" id="quick-install">
+<span id="id1"></span><h2>Quick Install<a class="headerlink" href="#quick-install" title="Permalink to this headline">¶</a></h2>
+<p>For an experienced and/or rather bold user, this is a 1
+paragraph version of the installation instructions:</p>
+<p>This should work on RedHat and its derivatives, and MacOS X. If this
+does not describe your case, you will very likely have to install and
+configure at least some of the components manually. Meaning, you may
+consider reading through the chapters that follow! Still here? Great.
+Prerequisites: Sun/Oracle Java JDK 1.6_31+ and a “virgin” installation
+of Glassfish v3.1.2; PostgreSQL v8.3+, configured to listen to network
+connections and support password authentication on the localhost
+interface; you may need R as well. See the corresponding sections under
+“2. Prerequisites”, if necessary. Download the installer package from
+SourceForge:</p>
+<p><a class="reference external" href="http://sourceforge.net/projects/dvn/files/dvn">http://sourceforge.net/projects/dvn/files/dvn</a></p>
+<p>Choose the latest version and download the dvninstall zip file.</p>
+<p>Unzip the package in a temp location of your choice (this will create
+the directory <tt class="docutils literal"><span class="pre">dvninstall</span></tt>). Run the installer, as root:</p>
+<blockquote>
+<div><dl class="docutils">
+<dt><tt class="docutils literal"><span class="pre">cd</span> <span class="pre">dvninstall</span></tt></dt>
+<dd>./ <tt class="docutils literal"><span class="pre">install</span></tt></dd>
+</dl>
+</div></blockquote>
+<p>Follow the installation prompts. If it all works as it should, you
+will have a working DVN instance running in about a minute from now.</p>
+<p>Has it worked? Awesome! Now you may read the rest of the guide
+chapters at your own leisurely pace, to see if you need any of the
+optional components described there. And/or if you want to understand
+what exactly has just been done to your system.</p>
+</div>
+<div class="section" id="system-requirements">
+<h2>SYSTEM REQUIREMENTS<a class="headerlink" href="#system-requirements" title="Permalink to this headline">¶</a></h2>
+<p>Or rather, recommendations. The closer your configuration is to what’s
+outlined below, the easier it will be for the DVN team to provide
+support and answer your questions.</p>
+<ul class="simple">
+<li>Operating system - The production version of the Dataverse Network at
+IQSS (dvn.iq.harvard.edu) runs on RedHat Linux 5. Most of the DVN
+development is currently done on MacOS X. Because of our experience
+with RedHat and MacOS X these  are the recommended platforms. You
+should be able to deploy the application .ear file on any other
+platform that supports Java. However, the automated installer we
+provide will likely work on RedHat and MacOS only. Some information
+provided in this guide is specific to these 2 operating systems. (Any
+OS-specific instructions/examples will be clearly marked, for
+example:<tt class="docutils literal"><span class="pre">[MacOS-specific:]</span></tt>)</li>
+<li>CPU - The production IQSS Dataverse Network runs on generic,
+multi-core 64-bit processors.</li>
+<li>Memory - The application servers currently in production at the IQSS
+have 64 GB of memory each.  Development and testing systems require a
+minimum of 2 gigabyte of memory.</li>
+<li>Disk space - How much disk space is required depends on the amount of
+data that you expect to serve. The IQSS Dataverse Network file system
+is a standalone NetApp with 2 TB volume dedicated to the DVN data.</li>
+<li>Multiple servers – All the DVN components can run on the same server.
+On a busy, hard-working production network the load can be split
+across multiple servers. The 3 main components, the application
+server (Glassfish), the database (Postgres) and R can each run on its
+own host. Furthermore, multiple application servers sharing the same
+database and R server(s)  can be set up behind a load balancer.
+Developers would normally run Glassfish and Postgres on their
+workstations locally and use a shared R server.</li>
+<li>If it actually becomes a practical necessity to bring up more servers
+to handle your production load, there are no universal instructions
+on how to best spread it across extra CPUs. It will depend on the
+specifics of your site, the nature of the data you serve and the
+needs of your users, whether you’ll benefit most from dedicating
+another server to run the database, or to serve R requests. Please
+see the discussion in the corresponding sections of the Prerequisites
+chapter.</li>
+</ul>

+<span id="id2"></span><h2>PREREQUISITES<a class="headerlink" href="#prerequisites" title="Permalink to this headline">¶</a></h2>
+<p>In this chapter, an emphasis is made on clearly identifying those
+components that are absolutely required for  every installation and
+marking any advanced, optional instructions as such.</p>
+<div class="section" id="glassfish">
+<h3>Glassfish<a class="headerlink" href="#glassfish" title="Permalink to this headline">¶</a></h3>
+<p>Version 3.1.2 is required.</p>
+<p>Make sure you have <strong>Sun/Oracle</strong><strong>Java JDK version 1.6, build 31</strong>
+or newer. It is available from
+<a class="reference external" href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">http://www.oracle.com/technetwork/java/javase/downloads/index.html</a>.</p>
+<p><strong>[note for developers:]</strong></p>
+<p>If you are doing this installation as part of your DVN software
+development setup: The version of NetBeans currently in use by the DVN
+team is 7.0.1, and it is recommended that you use this same version if
+you want to participate in the development. As of writing of this
+manual, NetBeans 7.0.1 installer bundle comes with an older version of
+Glassfish. So you will have to install Glassfish version 3.1.2
+separately, and then select it as the default server for your NetBeans
+project.</p>
+<p><strong>[/note for developers]</strong></p>
+<p>We <strong>strongly</strong> recommend that you install GlassFish Server 3.1.2,
+Open Source Edition, <strong>Full Platform</strong>. You are very likely to run into
+installation issues if you attempt to run the installer and get the
+application to work with a different version! Simply transitioning from
+3.1.1 to 3.1.2 turned out to be a surprisingly complex undertaking,
+hence this recommendation to all other installers and developers to stay
+with the same version.</p>
+<p>It can be obtained from</p>
+<p><a class="reference external" href="http://glassfish.java.net/downloads/3.1.2-final.html">http://glassfish.java.net/downloads/3.1.2-final.html</a></p>
+<p>The page contains a link to the installation instructions. However,
+the process is completely straightforward. You are given 2 options for
+the format of the installer package. We recommend that you choose to
+download it as a shell archive; you will need to change its executable
+permission, with <strong>chmod +x</strong>, and then run it, as root:</p>
+<p>./<strong>installer-filename.sh</strong></p>
+<p>[<strong>Important:]</strong></p>
+<p>Leave the admin password fields blank. This is not a security risk,
+since out of the box, Glassfish will only be accepting admin connections
+on the localhost interface. Choosing password at this stage however will
+complicate the installation process unnecessarily<strong>.</strong>If this is a
+developers installation, you can probably keep this configuration
+unchanged (admin on localhost only). If you need to be able to connect
+to the admin console remotely, please see the note in the Appendix
+section of the manual.</p>

+</div>
+<p>By default, most Postgres distributions are configured to listen to network connections on the localhost interface only; and to only support ident for authentication. (The MacOS installer may ask you if network connections should be allowed - answer &#8220;yes&#8221;). At a minimum, if GlassFish is running on the same host, it will also need to allow password authentication on localhost. So you will need to modify the &#8220;<tt class="docutils literal"><span class="pre">host</span> <span class="pre">all</span> <span class="pre">all</span> <span class="pre">127.0.0.1</span></tt>&#8221; line in your <tt class="docutils literal"><span class="pre">/var/lib/pgsq1/data/pg_hba.conf</span></tt> so that it looks like this:</p>

+<p>Also, the installer script needs to have direct access to the local PostgresQL server via Unix domain sockets. So this needs to be set to either &#8220;trust&#8221; or &#8220;ident&#8221;. I.e., your <strong>pg_hba.conf</strong> must contain either of the 2 lines below:</p>
+<div class="line-block">

+<div class="line">or</div>

+<p>Many modern OS distributions come pre-configured so that all the
+network ports are firewalled off by default.</p>
+<p>Depending on the configuration of your server, you may need to open some
+of the following ports.</p>
+<p>On a developers personal workstation, the user would normally access his

+required unless you want to give access to your DVN to another
+user/developer.</p>
+<p>When running a DVN that is meant to be accessible by network users: At a
+minimum, if all the components are running on the same server, the HTTP
+port 80 needs to be open. You may also want to open TCP 443, to be able
+to access Glassfish admin console remotely.</p>
+<p>If the DVN is running its own HANDLE.NET server (see Chapter 4.
+&#8220;Optional Components&#8221;), the TCP port 8000 and TCP/UDP ports 2641 are
+also needed.</p>
+<p>If the DVN application needs to talk to PostgreSQL and/or Rserve running

+HANDLE.NET Technical Manual:
+<a class="reference external" href="http://www.handle.net/tech_manual/Handle_Technical_Manual.pdf">http://www.handle.net/tech_manual/Handle_Technical_Manual.pdf</a>.</li>
+<li>Accept the default settings during installation, <strong>with one
+exception:</strong> do not encrypt private keys (this will make it easier to
+manage the service). <strong>Note</strong> that this means answer &#8216;n&#8217; when
+prompted &#8220;Would you like to encrypt your private key?(y/n). [y]:&#8221; If
+you accept the default &#8216;y&#8217; and then hit return when prompted for
+passphrase, this <strong>will</strong> encrypt the key, with a blank pass phrase!</li>
+<li>During the installation you will be issued an &#8220;authority prefix&#8221;.
+This is an equivalent of a domain name. For example, the prefix
+registered to the IQSS DVN is &#8220;1902.1&#8221;. The IDs issued to IQSS
+studies are of a form &#8220;1902.1/XXXX&#8221;, where &#8220;XXXX&#8221; is some unique
+identifier.</li>
+<li>Use <tt class="docutils literal"><span class="pre">psql</span></tt> or <tt class="docutils literal"><span class="pre">pgAdmin</span></tt> to execute the following SQL command:

+<p>This is a more detailed explanation of the statement made earlier in the &#8220;Prerequisites&#8221; section: &#8220;Only the advanced modes of serving quantitative data to the users require R.&#8221; <tt class="docutils literal"><span class="pre">[style?]</span></tt></p>
+<p>In this context, by “quantitative data” we mean data sets for which
+machine-readable, variable-level metadata has been defined in the DVN
+database. “Subsettable data” is another frequently used term, in the
+DVN parlance. The currently supported sources of subsettable data are
+SPSS and STATA files, as well as row tabulated or CSV files, with
+extra control cards defining the data structure and variable
+metadata. (See full documentation in User Guide for <a class="reference internal" href="dataverse-user-main.html#finding-and-using-data"><em>Finding and Using Data</em></a></p>
+<p>Once a “subsettable” data set is create, users can run online statistics and analysis on it. That’s where R is used. In our experience, most of the institutions who have installed the DVN did so primarily in order to share and process quantitative data. When this is the case, R must be considered a required component. But a DVN network built  to serve a collection of strictly human-readable (text, image, etc.) data, R will not be necessary at all.</p>

+<p>The Installer script (chapters Quick Install, Running the Installer.) automates the following tasks:</p>
+<ol class="arabic simple">
+<li>Checks the system for required components;</li>
+<li>Prompts the user for the following information:<ol class="loweralpha">
+<li>Location of the Glassfish directory;</li>
+<li>Access information (host, port, database name, username, password) for PostgresQL;</li>
+<li>Access information (host, port, username, password) for Rserve;</li>
+</ol>
+</li>

+<li>Using the <a class="reference internal" href="#glassfish-configuration-template"><em>Glassfish configuration template (section the Appendix)</em></a> and the information collected in step 2.b. above, creates the config file domain.xml and installs it the Glassfish domain directory.</li>
+<li>Copies additional configuration files (supplied in the dvninstall/config directory of the Installer package) into the config directory of the Glassfish domain.</li>
+<li>Installs Glassfish Postgres driver (supplied in the dvninstall/pgdriver directory of the Installer package) into the lib directory in the Glassfish installation tree.</li>
+<li>Attempts to start Glassfish. The config file at this point contains the configuration settings that the DVN will need to run (see section <a class="reference internal" href="#glassfish-configuration-individual-settings"><em>Glassfish Configuration, individual settings section</em></a> of the Appendix), but otherwise it is a &#8220;virgin&#8221;, fresh config. Glassfish will perform some initialization tasks on this first startup and deploy some internal apps.</li>
+<li>If step 5. succeeds, the Installer attempts to deploy the DVN application (the Java archive DVN-EAR.ear supplied with the installer).</li>
+<li>Stops Glassfish, populates the DVN database with the initial content (section <a class="reference internal" href="#postgresql-setup"><em>&#8220;PostgreSQL configuration&#8221;</em></a>&#8221; of the Appendix), starts Glassfish.</li>
+<li>Attempts to establish connection to Rserve, using the access information obtained during step 2.c. If this fails, prints a warning message and points the user to the Prerequisites section of this guide where R installation is discussed.</li>
+<li>Finally, prints a message informing the user that their new DVN should be up and running, provides them with the server URL and suggests that they visit it, to change the default passwords and perhaps start  setting up their Dataverse Network.</li>

+<p><a class="reference external" href="http://lockss.hmdc.harvard.edu/lockss/plugin/DVNOAIPlugin.jar">http://lockss.hmdc.harvard.edu/lockss/plugin/DVNOAIPlugin.jar</a></p>
+<p>As of January 2013 and DVN version 3.3, the plugin is compatible with the  LOCKSS daemon version 1.55. The plugin sources can be found in the main DVN source tree in <a class="reference external" href="https://dvn.svn.sourceforge.net/svnroot/dvn/dvn-app/trunk/src/DVN-lockss">https://dvn.svn.sourceforge.net/svnroot/dvn/dvn-app/trunk/src/DVN-lockss</a> (please note that the DVN project is currently <strong>in the process of moving to gitHub!</strong> The preserved copy of the 3.3 source will be left at the URL above, together with the information on the current location of the source repository).</p>
+<p>In order to crawl a DVN, the following steps need to be performed:</p>
+<ol class="arabic">
+<li><p class="first">Point your LOCKSS daemon to the plugin repository above. (Refer to the LOCKSS documentation for details);</p>
+</li>
+<li><p class="first">Create a LOCKSS Archival Unit for your target DVN:</p>
+<p>In the LOCKSS Admin Console, go to <strong>Journal Configuration</strong> -&gt; <strong>Manual Add/Edit</strong> and click on <strong>Add Archival Unit</strong>.</p>
+<p>On the next form, select <strong>DVNOAI</strong> in the pull down menu under <strong>Choose a publisher plugin</strong> and click <strong>Continue</strong>.</p>
+<p>Next configure the parameters that define your DVN Archival Unit. LOCKSS daemon can be configured to crawl either the entire holdings of a DVN (no OAI set specified), or a select Dataverse.</p>
+</li>
+</ol>
+<p>Note that LOCKSS crawling must be authorized on the DVN side. Refer to
+the <a class="reference internal" href="dataverse-user-main.html#edit-lockss-harvest-settings"><em>&#8220;Edit LOCKSS Settings&#8221;</em></a>
+section of the DVN Network Administrator Guide for the instructions on
+enabling LOCKSS crawling on the network level, and/or to the
+<a class="reference internal" href="dataverse-user-main.html#enabling-lockss-access-to-the-dataverse"><em>Enabling LOCKSS access to the Dataverse</em></a>
+of the Dataverse Administration Guide. Once you allow LOCKSS crawling of
+your Dataverse(s), you will need to enter the URL of the &#8220;LOCKSS
+Manifest&#8221; page provided by the DVN in the configuration above. For the
+network-wide archival unit this URL will be
+<tt class="docutils literal"><span class="pre">http</span></tt><tt class="docutils literal"><span class="pre">://&lt;YOUR</span> <span class="pre">SERVER&gt;/dvn/faces/ManifestPage.xhtml</span></tt>; for an

+<p>A Read Only Mode has been established in DVN to allow the application to remain available while deploying new versions or patches.  Users will be able to view data and metadata, but will not be able to add or edit anything.  Currently there is no way to switch to Read Only Mode through the application.
+In order to change the application mode you must apply the following queries through <tt class="docutils literal"><span class="pre">psql</span></tt> or <tt class="docutils literal"><span class="pre">pgAdmin</span></tt>:</p>
