You can either use a Handle server running on the same machine as DSpace, or you can install it on a separate machine. Installing it on the same machine is a little bit easier.  If you install it on a separate machine, you can use one Handle server for more than one DSpace installation.

To install your Handle resolver on the host where DSpace runs

...

Note
We recommend configuring your Handle server without a passphrase, as the current DSpace start-handle-server scripts do not yet support startup with a passphrase. If you choose to set a passphrase, you may need to start the Handle Server via: [dspace]\bin\dspace dsrun net.handle.server.Main [dspace]\handle-server

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

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

   1. If you are using Windows, the proper command is:

      Code Block
      [dspace]/bin/dspace dsrun net.handle.server.SimpleSetup [dspace]/handle-server

      Ensure that [dspace]/handle-server matches whatever you have in dspace.cfg for the handle.dir property. You will need to answer a series of qestions to configure the server. For the most part, you can use the default options, except you should choose to not  encrypt your certificates when prompted.

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"

   "enable_txn_queue" = "no"

   This tells the Handle server to get information about individual Handles from the DSpace code and to disable transaction replication. If you used the make-handle-config script, these should already be set in your config.dct file.

3. Once the configuration file has been generated, you will need to go to https://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/123456789". Replace 123456789 with the assigned naming authority prefix sent to you.  Also change the value of handle.prefix in [dspace]/config/local.cfg from "123456789" to your assigned naming authority prefix, so that DSpace will use that prefix in assigning new Handles.

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

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

   1. If you are using Windows, there is a corresponding 'start-handle-server.bat' script:

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

      
      

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.

To install a Handle resolver on a separate machine

...

Warning
title Not yet supported in DSpace 7
The option to run the Handle resolver on a separate machine is not yet available in DSpace 7 codebase.  See this ticket:  Jira server DuraSpace JIRA serverId c815ca92-fd23-34c2-8fe3-956808caf8c5 key DS-4314

...

1. Download the CNRI Handle Software: http:s//www.handle.net/download.html. In the tarball you'll find an README.txt with installation instructions -- follow it.
2. After installing the CNRI Handle Software you should have two directories: once that contains the CNRI software and one that contains the configuration of you local Handle Server. For the rest of this instruction we assume that the directory containing the CNRI Software is /hs/handle-9.1.0 and the directory containing the configuration of your local server is /hs/srv_1.  (We use the same paths here as CNRIs README.txt.)
3. Download the plugin from https://github.com/DSpace/Remote-Handle-Resolver/releases.  Select a release.  You can get the source and build it yourself, or just use the JAR file included in the release.  In either case, once you have a dspace-remote-handle-resolver-VERSION.jar, copy it to the directory containing the CNRI software (/hs/handle-9.1.0/lib). 
4. Create the directory /hs/srv_1/logs.

5. Create the following two files in /hs/srv_1.

   Code Block
   title log4j-handle-plugin.properties
   log4j.rootCategory=INFO, A1

   
   

   log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender

   
   

   log4j.appender.A1.File=/hs/srv_1/logs/handle-plugin.log

   
   

   log4j.appender.A1.DatePattern= '.' yyyy-MM-dd

   
   

   log4j.appender.A1.layout=org.apache.log4j.PatternLayout

   
   

   log4j.appender.A1.layout.ConversionPattern=%d %-5p %c @ %m%n

   
   

   log4j.logger.org.apache.axis.handlers.http.HTTPAuthHandler=INFO

   Change the path in the third line, if necessary.

   Code Block
   title handle-dspace-plugin.cfg
   dspace.handle.endpoint1 = http: //example.org/dspace/handleresolver

   If you are using XMLUI take a look in [dspace-install]/config/dspace.cfg, change the URL above to the value of your dspace.url and add /handleresolver to the end of it. If you are using JSPUI take a look in [dspace-install]/config/dspace.cfg, change the URL above to the value of your dspace.url and add /json/hdlresolver to the end of it.

   If you run more than one DSpace Installation, you may add more DSpace Endpoints.  Just increase the number at the end of the key for each:  endpoint2, endpoint3....

6. Edit the file /hs/srv_1/config.dct to include the following lines in the " server_config" clause:

   Code Block
   "storage_type" = "CUSTOM"

   
   

   "storage_class" = "org.dspace.handle.MultiRemoteDSpaceRepositoryHandlePlugin"

   
   

7. Edit /hs/handle-9.1.0/bin/hdl:
   1. Find a line that contains exec java ... net.handle.server.Main ...
   2. Add "-Dlog4j.configuration=file:///hs/srv_1/log4j-handle-plugin.properties -Ddspace.handle.plugin.configuration=/hs/srv_1/handle-dspace-plugin.cfg" right in front of net.handle.server.Main.
8. If your handle server is running, restart it.

Please note: The Handle Server will only start if it is able to connect to at least one running DSpace Installation. It only resolves the handles of the DSpace Installations that were running when it was started.

To install a Handle resolver on a separate machine using template handles

...

Instead of using the describd described plugin above, you can configure a Handle server (version 8+) to resolve handles based on a template. Template handle require less configuration than the plugin, and do not require an additional download. However, there are two things to keep in mind when using template handles:

...

1. Download the CNRI Handle Software: https://www.handle.net/download.html.
2. In the tarball you'll find an README.txt with installation instructions. Follow the directions to install and configure your Handle server. Importantly, make sure your prefixes are set correctly in the "auto_homed_prefixes" setting.

3. Edit the server's config.dct file to include the following line in the " server_config" clause:

   Code Block
   "namespace" = "<namespace><template delimiter'/'><value type='URL' index='1' data='https://demo.dspace.org/

   jspui/

   handle/${handle}'/></template></

   namespace>

   namespace>"

   
   

   In the "namespace" section, replace "https://demo.dspace.org/jspui/handle/" with the url endpoint for your DSpace server. The "${handle}" part of the template will be replaced with the full handle to be resolved.

4. If your handle server is running, restart it.

This configuration is a minimal example of how to configure template handles for DSpace. For more details about configuing configuring template handles, see the Handle Technical Manual, Chapter 11 (PDF download).
