EDG Server Platform Considerations

These sections describe some aspects of the server platform to consider prior to installing the EDG server.

Application Server and Supported Platforms

The EDG server uses Apache Tomcat running on Java.

For the details of your EDG server version, see the Supported Platforms page for compatible platform components (e.g., Java, database, etc.). This also includes sections with details and suggested configurations for installing on Linux or Windows Server.

Suggested Java Configuration

If you are using both TopBraid EDG and another TopBraid server application such as Explorer on the same machine, we recommend that you run each in a separate JVM by running them with separate instances of Tomcat.

It is necessary to ensure that you have adequate physical memory to run EDG and that you have configured your Web Application Server to use it. During the purchasing process you should have received a guide to Server Sizing Specifications. Please set these appropriate to your data and users. If you did not receive this, please contact TopQuadrant support.

See the installation instructions below for your operating system for more details concerning how to set the parameters.

Operating Systems

Installation on Linux

This section describes details and suggested configurations when using Linux as the base operating system and Tomcat as the Web Application Server.

A suggested configuration for Enterprise Data Governance is as follows:

Operating Systems	Current version of Linux with 2.6 or higher kernel
Java Runtime Environment	Java 11
Web Application Server	Apache Tomcat 9 latest (For Debian based Linux distributions, see the notes for using Tomcat 9: https://salsa.debian.org/java-team/tomcat9/blob/master/debian/README.Debian) Apache Tomcat 8.5 latest: see Supported Platforms for specific versions
Permissions	Full access to the Tomcat configuration area is required.

Enterprise Data Governance also requires that the nofile limit be increased as it opens a large number of JAR files, and each TDB database also has a large number of files. The default is 1024 open files and sockets. Reset this by adding the following two lines to the /etc/security/limits.conf configuration file:

tomcat8         soft    nofile          2048
tomcat8         hard    nofile          8192

Installation on Windows Server

This section describes details and suggested configurations when using Windows Server as the base operating system and Tomcat as the Web Application Server.

A suggested configuration for Enterprise Data Governance is as follows:

Operating Systems	Windows Server, (e.g. 2008, 2012, 2016) Administrator access is required for installation
Java Runtime Environment	Java 11
Web Application Server	Apache Tomcat 9 latest Apache Tomcat 8.5 latest See Supported Platforms for specific versions
