The software DSpace relies on does not come out of the box optimized for large repositories. Here are some tips to make it all run faster. |
Review the number of DSpace webapps you have installed in Tomcat
By default, DSpace includes a number of web applications which all interact with the underlying DSpace data model. The DSpace web applications include: XMLUI, JSPUI, OAI, RDF, REST, SOLR, SWORD, and SWORDv2. The only required web application is SOLR as it is utilized by several of the other web applications (XMLUI, JSPUI and OAI). See the Installing DSpace documentation for more information about each of these web applications.
Any of the other web applications can be removed from your Tomcat, if you have no plans to utilize that functionality. The fewer web applications you are running, the less memory you will require, as each of these applications will be allocated memory when started up by Tomcat.
Give Tomcat (DSpace UIs) More Memory

- Download the latest version of psi-probe from from https://code.googlegithub.com/ppsi-probe/psi-probe/
Unzip probe.war into [dspace]/webapps/
Code Block cd [dspace]/webapps/ wgetunzip https:~//psi-probe.googlecode.com/files/probe-2.3.3.zip unzip probe-2.3.31.0.zip unzip probe.war -d probe
Add a Context element in Tomcat's configuration ( in or in ) , and make it privileged (so that it can monitor the other webapps):
EITHER in$CATALINA_HOME/conf/server.xml
Code Block language xml <Context docBase="[dspace]/webapps/probe" privileged="true" path="/probe" />
OR in
$CATALINA_HOME
/conf/Catalina/localhost/probe.xml
Code Block language xml <Context docBase="[dspace]/webapps/probe" privileged="true" />
Edit
$CATALINA_HOME/conf/tomcat-users.xml
to add a user for loggin logging into psi-probe (see more in in https://code.googlegithub.com/ppsi-probe/psi-probe/wiki/InstallationApacheTomcat#SecurityInstallationApacheTomcat)Code Block <?xml version='1.0' encoding='utf-8'?> <tomcat-users> <user username="admin" password="t0psecret" roles="manager" /> </tomcat-users>
- Restart Tomcat
- Open http://yourdspace.com:8080/probe/ (edit domain and port number as necessary) in your browser and use the username and password from tomcat-users.xml to log in.
