CTS2-LE Installation and Deployment

This section describes how to install and deploy a CTS2-LE server instance along with the navigator front-end. It has to be ensured that the system fulfils the defined prerequisites. The following steps are aligned to the recommended system environment and hence offer commands on the basis of an Ubuntu-like OS.

Delivered artifacts

You will be receiving 3 artifacts that allow for a fast and clean installation of CTS2-LE.

• WebCts2LE.war
• a start-up directory which holds the licensed terminologies
• a script for loading the store content

General settings

Configure roles and users

Since the web application can be managed by means of the tomcat manager interface, it is useful to configure a role and a user. In /var/lib/tomcat7/conf/tomcat-users.xml add a role manager-gui and assign it to a user in the following manner:

<role rolename="manager-gui"/>
<user username="user" password="password" roles="manager-gui"/>

Increasing Java heap space

Experience has shown that increasing the heap space for tomcat positively influences the servers efficiency. Therefore, it is recommended to permanently set

CATALINA_OPTS="-Xms512m -Xmx900m"

Setting the resource root

Select a directory where the terminology store will be located. The directory has to be specified by setting an environment variable called CTS2LE_RESOURCE_ROOT.

Since the resource root is one of the building blocks of CTS2-LE, no arbitrary manipulation of the files within the directory should be done. Only apply changes to the files which are described in this section.
