For the Impatient

Since some users might want to get their test version up and running as fast as possible, offered below is an unsupported outline of getting DSpace to run quickly in a Unix-based environment using the DSpace source release.

Warning

Only experienced unix admins should even attempt the following without going to the detailed Installation Instructions

Code Block

useradd -m dspace
gunzip -c dspace-1.x-src-release.tar.gz | tar -xf -
createuser -U postgres -d -A -P dspace
createdb -U dspace -E UNICODE dspace
cd [dspace-source]/dspace/config
vi dspace.cfg
mkdir [dspace]
chown dspace [dspace]
su - dspace
cd [dspace-source]/dspace
mvn package
cd [dspace-source]/dspace/target/dspace-<version>-build
ant fresh_install
cp -r [dspace]/webapps/* [tomcat]/webapps
/etc/init.d/tomcat start
[dspace]/bin/dspace create-administrator

...

  • Apache Tomcat 5.5 or later. Tomcat can be downloaded from the following location: http://tomcat.apache.org.
    • Note that DSpace will need to run as the same user as Tomcat, so you might want to install and run Tomcat as a user called 'dspace'. Set the environment variable TOMCAT_USER appropriately.
    • You need to ensure that Tomcat has a) enough memory to run DSpace and b) uses UTF-8 as its default file encoding for international character support. So ensure in your startup scripts (etc) that the following environment variable is set: JAVA_OPTS="-Xmx512M -Xms64M -Dfile.encoding=UTF-8"

    • Modifications in [tomcat]/conf/server.xml: You also need to alter Tomcat's default configuration to support searching and browsing of multi-byte UTF-8 correctly. You need to add a configuration option to the <Connector> element in [tomcat]/config/server.xml: URIEncoding="UTF-8"e.g. if you're using the default Tomcat config, it should read:

      Code Block
      
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080"
              maxThreads="150"
              minSpareThreads="25"
	      maxSpareThreads="75"
              enableLookups="false"
              redirectPort="8443"
	      acceptCount="100"
              connectionTimeout="20000"
	      disableUploadTimeout="true"
              URIEncoding="UTF-8"/>

      You may change the port from 8080 by editing it in the file above, and by setting the variable CONNECTOR_PORT in server.xml.

  • Jetty or Caucho Resin DSpace will also run on an equivalent servlet Engine, such as Jetty (http://www.mortbay.org/jetty/index.html) or Caucho Resin (http://www.caucho.com/). Jetty and Resin are configured for correct handling of UTF-8 by default.

...

  • Binary Release (dspace-<version>-release.zip)
    • This distribution will be adequate for most cases of running a DSpace instance. It is intended to be the quickest way to get DSpace installed and running while still allowing for customization of the themes and branding of your DSpace instance.
    • This method allows you to customize DSpace configurations (in dspace.cfg) or user interfaces, using basic pre-built interface "overlays".
    • It downloads "precompiled" libraries for the core dspace-api, supporting servlets, taglibraries, aspects and themes for the dspace-xmlui, dspace-xmlui and other webservice/applications.
    • This approach only exposes selected parts of the application for customization. All other modules are downloaded from the 'Maven Central Repository' The directory structure for this release is the following:
      • [dspace-source]
        • dspace/ - DSpace 'build' and configuration module
  • Source Release (dspace-<version>-src-release.zip)
    • This method is recommended for those who wish to develop DSpace further or alter its underlying capabilities to a greater degree.
    • It contains all dspace code for the core dspace-api, supporting servlets, taglibraries, aspects and themes for Manakin (dspace-xmlui), and other webservice/applications.
    • Provides all the same capabilities as the binary release. The directory structure for this release is more detailed:
      • [dspace-source]
        • dspace/ - DSpace 'build' and configuration module
        • dspace-api/ - Java API source module
        • dspace-discovery - Discovery source module
        • dspace-jspui/ - JSP-UI source module
        • dspace-oai - OAI-PMH source module
        • dspace-xmlui - XML-UI (Manakin) source module
        • dspace-lni - Lightweight Network Interface source module
        • dspace-stats - Statistics source module
        • dspace-sword - SWORD (Simple Web-serve Offering Repository Deposit) deposit service source module
        • dspace-swordv2 - SWORDv2 source module
        • dspace-sword-client - XMLUI client for SWORD
        • pom.xml - DSpace Parent Project definition

...

This method gets you up and running with DSpace quickly and easily. It is identical in both the Default Release and Source Release distributions.

  1. Create the DSpace user. This needs to be the same user that Tomcat (or Jetty etc.) will run as. e.g. as rootrun:

    Code Block
    useradd -m dspace
  2. Download the latest DSpace release There are two version available with each release of DSpace: (dspace-1.x-release. and dspace-1.x-src-release.xxx); you only need to choose one. If you want a copy of all underlying Java source code, you should download the dspace-1.x-src-release.xxx Within each version, you have a choice of compressed file format. Choose the one that best fits your environment.
  3. Unpack the DSpace software. After downloading the software, based on the compression file format, choose one of the following methods to unpack your software:

    1. Zip file. If you downloaded dspace-1.8-release.zipdo the following:

      Code Block
      unzip dspace-1.8-release.zip

    2. .gz file. If you downloaded dspace-1.8-release.tar.gzdo the following:

      Code Block
      gunzip -c dspace-1.8-release.tar.gz | tar -xf -

    3. .bz2 file. If you downloaded _dspace-1.8-release.tar.bz2_do the following:

      Code Block
      bunzip2 dspace-1.8-release.tar.bz | tar -xf -

      For ease of reference, we will refer to the location of this unzipped version of the DSpace release as [dspace-source] in the remainder of these instructions. After unpacking the file, the user may which to change the ownership of the dspace-1.6-release to the 'dspace' user. (And you may need to change the group).

  4. Database Setup
    • Also see notes above
    • PostgreSQL:
      • A PostgreSQL JDBC driver is configured as part of the default DSpace build. You no longer need to copy any PostgreSQL jars to get PostgreSQL installed.

      • Create a dspace database user. This is entirely separate from the dspaceoperating-system user created above.

        Code Block
        createuser -U postgres -d -A -P dspace

        You will be prompted for the password of the PostgreSQL superuser (postgres). Then you'll be prompted (twice) for a password for the new dspace user.

      • Create a dspace database, owned by the dspace PostgreSQL user (you are still logged in at 'root'):

        Code Block
        createdb -U dspace -E UNICODE dspace

        You will be prompted for the password of the DSpace database user. (This isn't the same as the dspace user's UNIX password.)

    • Oracle:

      • Setting up DSpace to use Oracle is a bit different now. You will need still need to get a copy of the Oracle JDBC driver, but instead of copying it into the lib directory you will need to install it into your local Maven repository. (You'll need to download it first from this location: http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html.) Run the following command (all on one line):

        Code Block
        
mvn install:install-file
    -Dfile=ojdbc6.jar
    -DgroupId=com.oracle
    -DartifactId=ojdbc6
    -Dversion=11.2.0.3
    -Dpackaging=jar
    -DgeneratePom=true

      • You need to compile DSpace with an Oracle driver (ojdbc6.jar) corresponding to your Oracle version - update the version in [dspace-source]/pom.xmlE.g.:

        Code Block
        
<dependency>
  <groupId>com.oracle</groupId>
  <artifactId>ojdbc6</artifactId>
  <version>11.2.0.3</version>
</dependency>
      • Create a database for DSpace. Make sure that the character set is one of the Unicode character sets. DSpace uses UTF-8 natively, and it is required that the Oracle database use the same character set. Create a user account for DSpace (e.g. dspace,) and ensure that it has permissions to add and remove tables in the database.

      • Edit the [dspace-source]/dspace/config/dspace.cfgdatabase settings:

        Code Block
        
db.name   = oracle
db.driver = oracle.jdbc.OracleDriver
db.url = jdbc:oracle:thin:@host:port/SID

        Where SID is the SID of your database defined in tnsnames.ora, default Oracle port is 1521.
        Alternatively, you can use a full SID definition, e.g.:

        Code Block
        
db.url = jdbc:oracle:thin:@(description=(address_list=(address=(protocol=TCP)(host=localhost)(port=1521)))(connect_data=(service_name=DSPACE)))

        Also set the username and password of the database you created in step 3:

        Code Block
        
db.username = your_oracle_username
db.password = your_oracle_password
  5. Initial Configuration: Edit [dspace-source]/dspace/config/dspace.cfg, in particular you'll need to set these properties:
    • dspace.dir - must be set to the [dspace] (installation) directory.
    • dspace.url - complete URL of this server's DSpace home page.
    • dspace.hostname - fully-qualified domain name of web server.
    • dspace.name - "Proper" name of your server, e.g. "My Digital Library".
    • db.password - the database password you entered in the previous step.
    • mail.server - fully-qualified domain name of your outgoing mail server.
    • mail.from.address - the "From:" address to put on email sent by DSpace.
    • feedback.recipient - mailbox for feedback mail.
    • mail.admin - mailbox for DSpace site administrator.
    • alert.recipient - mailbox for server errors/alerts (not essential but very useful!)

    • registration.notify- mailbox for emails when new users register (optional)

      Info

      You can interpolate the value of one configuration variable in the value of another one. For example, to set feedback.recipient to the same value as mail.admin, the line would look like:
      feedback.recipient = ${mail.admin}
      Refer to the General Configuration section for details and examples of the above.

  6. DSpace Directory: Create the directory for the DSpace installation (i.e. [dspace]). As root(or a user with appropriate permissions), run:

    Code Block
    mkdir [dspace]
chown dspace [dspace]

    (Assuming the dspace UNIX username.)

  7. Installation Package: As the dspaceUNIX user, generate the DSpace installation package.

    Code Block
    
cd [dspace-source]/dspace/
mvn package
    Info
    titleDefaults to PostgreSQL settings

    Without any extra arguments, the DSpace installation package is initialized for PostgreSQL. If you want to use Oracle instead, you should build the DSpace installation package as follows:
    mvn -Ddb.name=oracle package

  8. Build DSpace and Initialize Database: As the dspace UNIX user, initialize the DSpace database and install DSpace to [dspace]_:

    Code Block
    cd [dspace-source]/dspace/target/dspace-[version]-build
ant fresh_install
    Info

    To see a complete list of build targets, run: ant help The most likely thing to go wrong here is the database connection. See the Common Problems Section.

  9. Deploy Web Applications:
    Anchor
    deployment
    deployment
    You have two choices or techniques for having Tomcat/Jetty/Resin serve up your web applications:
    • Technique A. Simple and complete. You copy only (or all) of the DSpace Web application(s) you wish to use from the [dspace]/webapps directory to the appropriate directory in your Tomcat/Jetty/Resin installation. For example:
      cp -R [dspace]/webapps/* [tomcat]/webapps* (This will copy all the web applications to Tomcat).
      cp -R [dspace]/webapps/jspui [tomcat]/webapps* (This will copy only the jspui web application to Tomcat.)

    • Technique B. Tell your Tomcat/Jetty/Resin installation where to find your DSpace web application(s). As an example, in the <Host> section of your [tomcat]/conf/server.xml you could add lines similar to the following (but replace [dspace]with your installation location):

      Code Block
      <!-- Define the default virtual host
	Note:  XML Schema validation will not work with Xerces 2.2.
	-->
	<Host name="localhost"  appBase="[dspace]/webapps"
	....

  10. Administrator Account:Create an initial administrator account:

    Code Block
    [dspace]/bin/dspace create-administrator
  11. Initial Startup!Now the moment of truth! Start up (or restart) Tomcat/Jetty/Resin. Visit the base URL(s) of your server, depending on which DSpace web applications you want to use. You should see the DSpace home page. Congratulations! Base URLs of DSpace Web Applications:

...

  1. For Production use: Follow this procedure to set up SSL on your server. Using a "real" server certificate ensures your users' browsers will accept it without complaints. In the examples below, $CATALINA_BASEis the directory under which your Tomcat is installed.

    1. Create a Java keystore for your server with the password changeit, and install your server certificate under the alias "tomcat". This assumes the certificate was put in the file server.pem:

      Code Block
      $JAVA_HOME/bin/keytool -import -noprompt -v -storepass changeit
	-keystore $CATALINA_BASE/conf/keystore -alias tomcat -file
	myserver.pem

    2. Install the CA (Certifying Authority) certificate for the CA that granted your server cert, if necessary. This assumes the server CA certificate is in ca.pem:

      Code Block
      $JAVA_HOME/bin/keytool -import -noprompt -storepass changeit
	-trustcacerts -keystore $CATALINA_BASE/conf/keystore -alias ServerCA
	-file ca.pem

    3. Optional – ONLY if you need to accept client certificates for the X.509 certificate stackable authentication module See the configuration section for instructions on enabling the X.509 authentication method. Load the keystore with the CA (certifying authority) certificates for the authorities of any clients whose certificates you wish to accept. For example, assuming the client CA certificate is in client1.pem:

      Code Block
      $JAVA_HOME/bin/keytool -import -noprompt -storepass changeit
	-trustcacerts -keystore $CATALINA_BASE/conf/keystore  -alias client1
	-file client1.pem

    4. Now add another Connector tag to your server.xmlTomcat configuration file, like the example below. The parts affecting or specific to SSL are shown in bold. (You may wish to change some details such as the port, pathnames, and keystore password)

      Code Block
      <Connector port="8443"
               maxThreads="150" minSpareThreads="25"
	           maxSpareThreads="75"
               enableLookups="false"
	           disableUploadTimeout="true"
               acceptCount="100" debug="0"
              scheme="https" secure="true" sslProtocol="TLS"
	keystoreFile="conf/keystore" keystorePass="changeit" clientAuth="true" - ONLY if using client X.509 certs for authentication!
	truststoreFile="conf/keystore" trustedstorePass="changeit" />

      Also, check that the default Connector is set up to redirect "secure" requests to the same port as your SSL connector, e.g.:

      Code Block
      <Connector port="8080"
                 maxThreads="150" minSpareThreads="25"
	             maxSpareThreads="75"
                 enableLookups="false"
	             redirectPort="8443"
                 acceptCount="100" debug="0"  	/>
  2. Quick-and-dirty Procedure for Testing: If you are just setting up a DSpace server for testing, or to experiment with HTTPS, then you don't need to get a real server certificate. You can create a "self-signed" certificate for testing; web browsers will issue warnings before accepting it but they will function exactly the same after that as with a "real" certificate. In the examples below, $CATALINA_BASEis the directory under which your Tomcat is installed.
    1. Optional – ONLY if you don't already have a server certificate. Follow this sub-procedure to request a new, signed server certificate from your Certifying Authority (CA):

      • Create a new key pair under the alias name "tomcat". When generating your key, give the Distinguished Name fields the appropriate values for your server and institution. CN should be the fully-qualified domain name of your server host. Here is an example:

        Code Block
        
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keysize
	1024 \
  -keystore $CATALINA_BASE/conf/keystore -storepass changeit
	-validity 365 \
  -dname 'CN=dspace.myuni.edu, OU=MIT Libraries, O=Massachusetts
	Institute of Technology, L=Cambridge, S=MA, C=US'

      • Then, create a CSR (Certificate Signing Request) and send it to your Certifying Authority. They will send you back a signed Server Certificate. This example command creates a CSR in the file tomcat.csr

        Code Block
        
$JAVA_HOME/bin/keytool -keystore $CATALINA_BASE/conf/keystore
	-storepass changeit \
   -certreq -alias tomcat -v -file tomcat.csr

      • Before importing the signed certificate, you must have the CA's certificate in your keystore as a trusted certificate. Get their certificate, and import it with a command like this (for the example mitCA.pem):

        Code Block
        
$JAVA_HOME/bin/keytool -keystore $CATALINA_BASE/conf/keystore
	-storepass changeit \
     -import -alias mitCA -trustcacerts -file mitCA.pem

      • Finally, when you get the signed certificate from your CA, import it into the keystore with a command like the following example: (cert is in the file signed-cert.pem)

        Code Block
        
$JAVA_HOME/bin/keytool -keystore $CATALINA_BASE/conf/keystore
	-storepass changeit \
     -import -alias tomcat -trustcacerts -file signed-cert.pem

        Since you now have a signed server certificate in your keystore, you can, obviously, skip the next steps of installing a signed server certificate and the server CA's certificate.

    2. Create a Java keystore for your server with the password changeit, and install your server certificate under the alias "tomcat". This assumes the certificate was put in the file server.pem:

      Code Block
      
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore
	$CATALINA_BASE/conf/keystore -storepass changeit

      When answering the questions to identify the certificate, be sure to respond to "First and last name" with the fully-qualified domain name of your server (e.g. test-dspace.myuni.edu). The other questions are not important.

    3. Optional – ONLY if you need to accept client certificates for the X.509 certificate stackable authentication module See the configuration section for instructions on enabling the X.509 authentication method. Load the keystore with the CA (certifying authority) certificates for the authorities of any clients whose certificates you wish to accept. For example, assuming the client CA certificate is in client1.pem:

      Code Block
      
$JAVA_HOME/bin/keytool -import -noprompt -storepass changeit
	-trustcacerts -keystore $CATALINA_BASE/conf/keystore  -alias client1
	-file client1.pem
    4. Follow the procedure in the section above to add another Connector tag, for the HTTPS port, to your server.xml file.

...

If you are using X.509 Client Certificates for authentication: add these configuration options to the appropriate httpd configuration file, e.g. ssl.conf, and be sure they are in force for the virtual host and namespace locations dedicated to DSpace:

Code Block

##  SSLVerifyClient can be "optional" or
	"require"
        SSLVerifyClient optional
        SSLVerifyDepth  10
        SSLCACertificateFile
	path-to-your-client-CA-certificate
        SSLOptions StdEnvVars ExportCertData

...

A Handle server runs as a separate process that receives TCP requests from other Handle servers, and issues resolution requests to a global server or servers if a Handle entered locally does not correspond to some local content. The Handle protocol is based on TCP, so it will need to be installed on a server that can broadcast and receive TCP on port 2641.

  1. To configure your DSpace installation to run the handle server, run the following command:

    Code Block
    [dspace]/bin/dspace make-handle-config [dspace]/handle-server

    Ensure that [dspace]/handle-server matches whatever you have in dspace.cfg for the handle.dir property.

  2. Edit the resulting [dspace]/handle-server/config.dct file to include the following lines in the "server_config"clause:

    Code Block
    "storage_type" = "CUSTOM"
"storage_class" = "org.dspace.handle.HandlePlugin"

    This tells the Handle server to get information about individual Handles from the DSpace code.

  3. Once the configuration file has been generated, you will need to go to http://hdl.handle.net/4263537/5014 to upload the generated sitebndl.zip file. The upload page will ask you for your contact information. An administrator will then create the naming authority/prefix on the root service (known as the Global Handle Registry), and notify you when this has been completed. You will not be able to continue the handle server installation until you receive further information concerning your naming authority.
  4. When CNRI has sent you your naming authority prefix, you will need to edit the config.dct file. The file will be found in /[dspace]/handle-server. Look for "300:0.NA/YOUR_NAMING_AUTHORITY". Replace YOUR_NAMING_AUTHORITY with the assigned naming authority prefix sent to you.

  5. Now start your handle server (as the dspace user):

    Code Block
    [dspace]/bin/start-handle-server

    Note that since the DSpace code manages individual Handles, administrative operations such as Handle creation and modification aren't supported by DSpace's Handle server.

Updating Existing Handle Prefixes

...

The URL for pinging Google, and in future, other search engines, is configured in [dspace-space]/config/dspace.cfg using the sitemap.engineurls setting where you can provide a comma-separated list of URLs to 'ping'.

You can generate the sitemaps automatically every day using an additional cron job:

Code Block

# Generate sitemaps


0 6 * * * [dspace]/bin/dspace generate-sitemaps

...

DSpace uses the Apache Solr application underlaying the statistics. There is no need to download any separate software. All the necessary software is included. To understand all of the configuration property keys, the user should refer to DSpace Statistic Configuration for Statistics for detailed configuration information.

  1. DSpace Configuration for Accessing Solr. In the dspace.cfgfile review the following fields to make sure they are uncommented:

    Code Block
    solr.log.server = ${dspace.baseUrl}/solr/statistics
solr.dbfile = ${dspace.dir}/config/GeoLiteCity.dat
solr.spiderips.urls = http://iplists.com/google.txt, \
                      http://iplists.com/inktomi.txt, \
                      http://iplists.com/lycos.txt, \
                      http://iplists.com/infoseek.txt, \
                      http://iplists.com/altavista.txt, \
                      http://iplists.com/excite.txt, \
                      http://iplists.com/misc.txt, \
                      http://iplists.com/non_engines.txt

  2. DSpace logging configuration for Solr. If your DSpace instance is protected by a proxy server, in order for Solr to log the correct IP address of the user rather than of the proxy, it must be configured to look for the X-Forwarded-For header.  This feature can be enabled by ensuring the following setting is uncommented in the logging section of dspace.cfg:

    Code Block
    useProxies = true
  3. Configuration Control. In the [dspace]/config/modules/solr-statistics.cfg set file set the following property key: _statistics.item.authorization.admin=true_. This will require the user to sign on in to see that statistics. Setting the statistics to "false" will make them publicly available.
  4. Final steps.

    • Perform the following step:

      Code Block
      
cd [dspace-source]/dspace
mvn package
cd [dspace-source]/dspace/target/dspace-<version>-build
ant -Dconfig=[dspace]/config/dspace.cfg update
cp -R [dspace]/webapps/* [TOMCAT]/webapps

      If you only need to build the statistics, and don't make any changes to other web applications, you can replace the copy step above with: cp -R [dspace]/webapps/solr [TOMCAT]/webapps

    • Restart your webapps (Tomcat/Jetty/Resin)

...

You have two options to install/update this file:

  1. Attempt to re-run the automatic installer from your DSpace Source Directory ([dspace-source]). This will attempt to automatically download the database file, unzip it and install it into the proper location:

    Code Block
    ant update_geolite
    • NOTE: If the location of the GeoLite Database file is known to have changed, you can also run this auto-installer by passing it the new URL of the GeoLite Database File: ant -Dgeolite=[full-URL-of-geolite] update_geolite
  2. OR, you can manually install the file by performing these steps yourself:

...

  1. Download the DSpace source from SourceForge and unzip it (WinZip will do this)
  2. Ensure the PostgreSQL service is running, and then run pgAdmin III (Start -> PostgreSQL 8.0 -> pgAdmin III). Connect to the local database as the postgres user and:
    • Create a 'Login Role' (user) called dspace with the password dspace
    • Create a database called dspace owned by the user dspace, with UTF-8 encoding
  3. Update paths in [dspace-source]\dspace\config\dspace.cfg

    • Note: Use forward slashes / for path separators, though you can still use drive letters, e.g.: dspace.dir = C:/DSpaceAlso, make sure you change all of the parameters with file paths to suit, specifically:

      Code Block
      dspace.dir
config.template.log4j.properties
config.template.log4j-handle-plugin.properties
config.template.oaicat.properties
assetstore.dir
log.dir
upload.temp.dir
report.dir
handle.dir
  4. Create the directory for the DSpace installation (e.g. C:/DSpace)

  5. Generate the DSpace installation package by running the following from command line (cmd) :

    Code Block
    
cd [dspace-source]/dspace/
mvn package
    • Note #1: This will generate the DSpace installation package in your [dspace-source]/dspace/target/dspace-[version]-build/ directory.

    • Note #2:Without any extra arguments, the DSpace installation package is initialized for PostgreSQL. If you want to use Oracle instead, you should build the DSpace installation package as follows:

      Code Block
      mvn -Ddb.name=oracle package

  6. Initialize the DSpace database and install DSpace to [dspace] (e.g. C:\DSpace) by running the following from command line from your [dspace-source]/dspace/target/dspace-[version]-build/directory:

    Code Block
    ant fresh_install
    • Note: to see a complete list of build targets, run: ant help

  7. Create an administrator account, by running the following from your [dspace] (e.g. C:\DSpace) directory:

    Code Block
    [dspace]\bin\dspace create-administrator
  8. Copy the Web application directories from [dspace]\webapps to Tomcat's webapps dir, which should be somewhere like C:\Program Files\Apache Software Foundation\Tomcat\webapps

    • Alternatively, Tell your Tomcat installation where to find your DSpace web application(s). As an example, in the <Host> section of your [tomcat]/conf/server.xml you could add lines similar to the following (but replace [dspace]with your installation location):

      Code Block
      
<!-- DEFINE A CONTEXT PATH FOR DSpace XML User Interface  -->
<Context path="/xmlui" docBase="[dspace]/webapps/xmlui" debug="0"
	reloadable="true" cachingAllowed="false"
	allowLinking="true"/>

<!-- DEFINE A CONTEXT PATH FOR DSpace JSP User Interface  -->
<Context path="/jspui" docBase="[dspace]/webapps/jspui" debug="0"
	reloadable="true" cachingAllowed="false"
	allowLinking="true"/>

<!-- DEFINE A CONTEXT PATH FOR DSpace OAI User Interface  -->
<Context path="/oai" docBase="[dspace]/webapps/oai" debug="0"
	reloadable="true" cachingAllowed="false"
	allowLinking="true"/>

<!-- DEFINE ADDITIONAL CONTEXT PATHS FOR OTHER DSPACE WEB APPLICATIONS (SOLR, SWORD, LNI, etc.).
     CHANGE THE VALUE OF "[app]" FOR EACH APPLICATION YOU WISH TO ADD -->
<Context path="/[app]" docbase="[dspace]/webapps/[app]" debug="0"
	reloadable="true" cachingAllowed="false"
	allowLinking="true"/>
  9. Start the Tomcat service
  10. Browse to either http://localhost:8080/jspui or http://localhost:8080/xmlui. You should see the DSpace home page for either the JSPUI or XMLUI, respectively.

  • Database errors occur when you run ant fresh_install: There are two common errors that occur.

    • If your error looks like this:

      Code Block
      [java] 2004-03-25 15:17:07,730 INFO
	    org.dspace.storage.rdbms.InitializeDatabase @ Initializing Database
[java] 2004-03-25 15:17:08,816 FATAL
	    org.dspace.storage.rdbms.InitializeDatabase @ Caught exception:
[java] org.postgresql.util.PSQLException: Connection refused. Check
	    that the hostname and port are correct and that the postmaster is
	    accepting TCP/IP connections.
[java]     at
	    org.postgresql.jdbc1.AbstractJdbc1Connection.openConnection(AbstractJd
bc1Connection.java:204)
[java]     at org.postgresql.Driver.connect(Driver.java:139)

      it usually means you haven't yet added the relevant configuration parameter to your PostgreSQL configuration (see above), or perhaps you haven't restarted PostgreSQL after making the change. Also, make sure that the db.username and db.password properties are correctly set in [dspace]/config/dspace.cfg. An easy way to check that your DB is working OK over TCP/IP is to try this on the command line:

      Code Block
      
psql -U dspace -W -h localhost

      Enter the dspace database password, and you should be dropped into the psql tool with a dspace=> prompt.

    • Another common error looks like this:

      Code Block
      [java] 2004-03-25 16:37:16,757 INFO
	    org.dspace.storage.rdbms.InitializeDatabase @ Initializing Database

[java]     at java.security.AccessController.doPrivileged(Native
	   Method)
[java]     at
	   java.net.URLClassLoader.findClass(URLClassLoader.java:186)

      This means that the PostgreSQL JDBC driver is not present in [dspace]/lib. See above.

  • GeoLiteCity Database file fails to download or install, when you run ant fresh_install: There are two common errors that may occur:

    • If your error looks like this:

      Code Block
      [get] Error getting http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz to /usr/local/dspace/config/GeoLiteCity.dat.gz

BUILD FAILED
/dspace-release/dspace/target/dspace-1.8.0-build/build.xml:931: java.net.ConnectException: Connection timed out

      it means that you likely either (a) don't have an internet connection to download the necessary GeoLite Database file (used for DSpace Statistics), or (b) the GeoLite Database file's URL is no longer valid. You should be able to resolve this issue by following the "Manually Installing/Updating GeoLite Database File" instructions above.

    • Another common message looks like this:

      Code Block
      [echo] WARNING : FAILED TO DOWNLOAD GEOLITE DATABASE FILE
[echo]          (Used for DSpace Solr Usage Statistics)

      Again, this means the GeoLite Database file cannot be downloaded or is unavailable for some reason. You should be able to resolve this issue by following the "Manually Installing/Updating GeoLite Database File" instructions above.

General DSpace Issues

  • Tomcat doesn't shut down: If you're trying to tweak Tomcat's configuration but nothing seems to make a difference to the error you're seeing, you might find that Tomcat hasn't been shutting down properly, perhaps because it's waiting for a stale connection to close gracefully which won't happen.
    • To see if this is the case, try running: ps -ef | grep java and look for Tomcat's Java processes. If they stay around after running Tomcat's shutdown.sh script, trying running kill on them (or kill -9 if necessary), then starting Tomcat again.
  • Database connections don't work, or accessing DSpace takes forever: If you find that when you try to access a DSpace Web page and your browser sits there connecting, or if the database connections fail, you might find that a 'zombie' database connection is hanging around preventing normal operation.
    • To see if this is the case, try running: ps -ef | grep postgres

    • You might see some processes like this:

      Code Block
      dspace 16325  1997  0  Feb 14  ?         0:00 postgres: dspace dspace    127.0.0.1 idle in transaction

      This is normal. DSpace maintains a 'pool' of open database connections, which are re-used to avoid the overhead of constantly opening and closing connections. If they're 'idle' it's OK; they're waiting to be used.

    • However sometimes, if something went wrong, they might be stuck in the middle of a query, which seems to prevent other connections from operating, e.g.:

      Code Block
      dspace 16325  1997  0  Feb 14  ?         0:00 postgres: dspace dspace    127.0.0.1 SELECT

      This means the connection is in the middle of a SELECT operation, and if you're not using DSpace right that instant, it's probably a 'zombie' connection. If this is the case, try running kill on the process, and stopping and restarting Tomcat.
