System Requirements

The system requirements depends on the requirements of your reports, that is to say on the number of concurrently requested reports, the complexity of the reports and also the number of rows fetched from the database. The following requirements are primarily for the i-net Clear Reports server.

Minimum System Requirements

Installed Report Server / i-net Designer

The following 64-bit operating systems are supported:

  • Windows 8 or above
  • Windows Server 2012 or above
  • Ubuntu 18.04
  • RedHat 6.x or 7.x
  • macOS 10.10 or above

A graphical user interface on the server is not required.

Installation on other Operating Systems

Installing the i-net Clear Reports server on other operating system is generally supported when a supported Java VM is available. In that case, please download the respective SDK.

Note: custom startup scripts will have to be created as there is no automatic configuration.


Running i-net Clear Reports in Docker container is supported. Please check the website for technical license requirements.

Remote Designer

The remote Designer requires an installed Java SE 11 or OpenWebStart.

Application Server

Application Server implementing the Servlet Specifications 3.1 including WebSocket 1.1 are supported. They have to be run using at least Java EE 7 (Java 8) or Jakarta EE 8 (Java 11). Jakarta EE 9 with Servlet Specifications 5.0 and WebSockets 2.0 or higher is not supported.

SDK (Java)

Java 11 is required to use the Java API of i-net Clear Reports.


Requires .NET Framework 4.6.1 and Java 11.


The minimum hardware requirements are 1.5 GB hard disk for a full installation. This includes 500 MB installation directory and 1 GB for the Temp directory of the system.


The i-net Clear Reports report server can run with processors starting at 1GHz but will require better processors to decrease executing time.

Supported browser versions

The remote interface and HTML Viewer were tested with the following browsers: (new) Microsoft Edge, Firefox, Safari and Chrome. We recommend the most recent browser versions.

Additional Information

If you use i-net Clear Reports Plus then you can use database cache or hard disk cache instead of memory cache. In this case finished pages are stored in a database or on a hard drive so that less memory is used for caching.

Requirements can be higher if you execute large reports with a lot of pages and/or a lot of users execute the reports.

To see the memory requirements of a single report you can export it into a PDF file. The size of the created PDF file corresponds to the memory requirements of the report.

In addition to the product requirements, please note the System Compatibility list for Java 11 by Oracle: https://www.oracle.com/technetwork/java/javase/documentation/jdk11certconfig-5069638.html
