iteraplan is a client/server application. This chapter describes the requirements on both the client and the server side.

Overview of Required Infrastructure

iteraplan is a web application which runs on a central server. On the client side, the application requires a web browser; on the server side, it requires a Java servlet engine, which provides the runtime environment for the application, plus a relational database in which the application data can be stored.

Client Requirements

On the client side, iteraplan only needs a standard web browser. We recommend an up-to-date Mozilla Firefox or Microsoft Internet Explorer 9, 10 or 11.

The browser's data privacy settings must be configured to accept cookies and JavaScript.

Please note that Internet Explorer 8 and older are no longer supported. Please note that Chrome is not supported.

iteraplan is an application based on Java server pages/ Java servlets and therefore requires a servlet engine. The server with this engine must be connected to the local network and be able to respond to requests submitted with HTTP/HTTPS.

At present, Apache Tomcat 6.0 and Apache Tomcat 7.0 are supported as the servlet engine. Please bear in mind that iteraplan is unable to run on earlier Tomcat versions. If you need support for more recent versions or for other servlet engines and application servers, please consult iteraplan support first to learn about known or potential issues.

Please verify that Apache Tomcat is installed, and that the CATALINA_HOME environment variable references the Tomcat installation folder. CATALINA_HOME must be created as a system wide environment variable. Please refer to your operating system manual for instructions on creating system wide environment variables. For Windows systems, Microsoft provides information in knowledge base entry KB310519.
Some Tomcat configuration options must be changed in order to run iteraplan successfully. Please follow these instructions.

Also make sure that you have write access to the subfolder webapps of the Tomcat installation folder, as the iteraplan installer will write to this folder later on.

A relational database is required for storing the application data. The application officially supports the database systems Oracle 10g/11g/12c and MySQL Versions 5.0.x, 5.1.x and 5.5.x. Make sure that one of these two database products is installed. The procedure for creating the database schemas is described on a separate page. If you are planning on using other database systems, you should first discuss this with iteratec.

Before installing the application with the iteraplan Installer utility, you must first install Java runtime environment (JRE) Version 6 or 7 (64bit). The JRE is also a prerequisite for running the Tomcat servlet engine. The application officially supports the Java runtime environments by Oracle. JREs from other vendors are not tested and not supported, although they might work.

Verify that you have the correct version of Java installed and that the Java /bin folder is included in the PATH environment variable (or Path - environment variables are not case sensitive in Windows). In addition, the environment variable JRE_HOME (alternatively: JAVA_HOME) must be set to the installation folder of the Java runtime or development environment. You can check the current environment variable values by running set in a command line window.
