Hardware Recommendations

You can install and run VIVO on most modern PC, laptop, or server hardware. Whilst the application layer needs a reasonable amount of memory, the majority of the workload is placed on the storage layers, which as a semantic web application means the triple store. As VIVO aims to be agnostic to the triple store, the precise requirements will depend on your choice of triple store. However, the default configuration is to use Jena SDB backed by MySQL - in this setup, it is recommended that you have very high IO bandwidth for the file system used by MySQL, and significant memory for caching layers of the database engine.

Minimum Specification

2 core x64 processor, 2GB RAM, 100GB HDD

Recommended Specification

4 core x64 processor, 16GB RAM, 500GB SSD

Note: I/O performance for MySQL is critical to the responsiveness of the application. The fastest SSD you can specify will help, as will having direct (e.g. not virtualised) access to it.

However, most sites will run their installations on a Linux server, and you may find that it is easier to follow the installation instructions on a Linux / UNIX variant. Notably, if you are running Windows, you may need to stop running processes (e.g. Tomcat) in order to complete some of the instructions, due to file locking semantics on Windows.

8

The minimum requirement is Java 7, however 8 is preferred for performance. Both OpenJDK and Oracle JVMs are compatible. Other JVMs that meet the JDK 7 specification may work, but have not been tested.

...

Note that you need to have the full Java Development Kit installed in order for Tomcat to operate correctly - the runtime alone is not sufficient.

Maven Maven

Maven 3.0.3 or later

Maven can be downloaded from the following location: http://maven.apache.org/download.html, although you may use a version supplied by your operating system / package manager, providing it meets the minimum requirements.

Configuring a Proxy

You can configure a proxy to use for some or all of your HTTP requests in Maven. The username and password are only required if your proxy requires basic authentication (note that later releases may support storing your passwords in a secured keystore‚ in the mean time, please ensure your settings.xml file (usually ${user.home}/.m2/settings.xml) is secured with permissions appropriate for your operating system).

Example:

...

<settings>
  .
  .
  <proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy.somewhere.com</host>
      <port>8080</port>
      <username>proxyuser</username>
      <password>somepassword</password>
      <nonProxyHosts>www.google.com|*.somewhere.com</nonProxyHosts>
    </proxy>
  </proxies>
