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.
On the client side, iteraplan only requires a web browser. We recommend using the latest version of Mozilla Firefox.

* Oracle 12c is only supported with the bug fix/patch No. 18430870 applied to the database. Without the patch iteraplan will not work correctly.
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.
Please verify that a supported version of 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. Make sure that one of the supported database products is installed. The procedure for creating the database schemas is described on a separate page.
Before installing the application with the iteraplan Installer utility, you must first install a compatible Java runtime environment (JRE). The JRE is also a prerequisite for running the Tomcat servlet engine. The application supports the Java runtime environments by Oracle. JREs from other vendors are not tested and not supported, although they might work.
Please verify 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.
The performance of iteraplan depends on many different parameters. Therefore there are neither general established numbers for precise hardware requirements nor a set of rules for iteraplan configuration.
When considering iteraplan's performance the following hints might be helpful nevertheless:
On the server side more memory is more important than more CPU power in most cases. On the client side more CPU power is more important than more memory in most cases.
