Download the 1.9.x distribution release from the VIVO repository on GitHub. The standard distribution consists of the projects required to create a home directory for VIVO, and to copy the web application and search index. All the compiled code and dependencies are resolved from the Maven central repository at the time you run Maven.

Preparing the Installation Settings

In order to fully To install VIVO, you need to create a settings file that provides some essential information:

app-name

...

Configure and Start Tomcat

Set JVM parameters

VIVO copies small sections of your RDF database into memory in order to serve Web requests quickly (the in-memory copy and the underlying database are kept in synch as edits are performed).

VIVO may require more memory than allocated to Tomcat by default. With most installations of Tomcat, the setenv.sh or setenv.bat file in Tomcat's bin directory is a convenient place to set the memory parameters. If this file does not exist in Tomcat's bin directory, you can create it. 

For example:

export CATALINA_OPTS="-Xms512m -Xmx512m -XX:MaxPermSize=128m"

This tells Tomcat to allocate an initial heap of 512 megabytes, a maximum heap of 512 megabytes, and a PermGen space of 128 megs. Larger values may be required, especially for production installations in large enterprises. In general, VIVO runs more quickly if given more memory.

...

VIVO is a multithreaded web application that may require more threads than are permitted under your operating system's installation's default configuration. Ensure that your installation can support the required number of threads by making for your application.  For a Linux production environment you may wish to make the following edits to /etc/security/limits.conf, replacing apache and tomcat with the appropriate user or group name for your setup:

apache hard nproc 400

tomcat hard nproc 1500

Set URI encoding

In order for VIVO to correctly handle international characters, you must configure Tomcat to conform to the URI standard by accepting percent-encoded UTF-8.

Edit Tomcat's conf/server.xml and add the following attribute to each of the Connector elements: URIEncoding="UTF-8".

<Server ...>

  <Service ...>

    <Connector ... URIEncoding="UTF-8"/>

      ...

    </Connector>

  </Service>

</Server>


Some versions of Tomcat already include this attribute as the default.

Take care when creating Context elements
