Hardware requirements

The minimum hardware requirement for LuciadFusion is any system that is capable of meeting the software requirements listed in this article.

You do not need a high-end graphics card to run any of the LuciadFusion components mentioned on this page. None of them require the hardware acceleration provided by such a GPU.

  • SSD or HDD: at least 7.2k RPM SATA 3.0 (6 Gbps). Optionally, for heavy usage due to a large number of clients, 10k or 15k SAS-3 (12 Gbps) or SATA 3.2 (16 Gbps).

  • CPU: 8-core

The usage of additional cores will result in better performance for importing data sources.

  • RAM: 16GB

  • Gigabit Ethernet

  • CPU: 8-core

  • RAM: 16GB

Supported platforms

You can develop and deploy LuciadFusion applications on the following platforms:

8.1 and above

64-bit

Windows Server

2012 and above

Linux support

LuciadLightspeed requires a minimum glibc (GNU C Library) version of 2.27 and the C++ ABI introduced in GCC 5.1.

This means that, among others, the following OS distributions are supported:

  • Red Hat Enterprise Linux 8 or newer

  • OpenSUSE Leap 15.3 or newer

  • Ubuntu 18.04 or newer

  • Debian 10 or newer

Linux distributions using old ABI

LuciadLightspeed does not support Linux distributions using the old ABI. This means that you cannot develop and deploy LuciadLightspeed on RHEL 7 or CentOS 7.

Supported browsers for LuciadFusion Studio

To use the LuciadFusion Studio frontend application on a client machine, you need to run it in one of the supported browsers:

  • Chrome (latest version)

  • Firefox (latest version)

  • Edge (latest version)

  • Safari (latest version)

Supported databases

LuciadFusion can use several types of databases to hold configuration and data catalog information. The following databases are supported:

  • PostgreSQL versions 9.4, 9.5, 9.6, 10, 11, 12, 13, 14, 15 and 16, with the PostGIS and pgcrypto extensions

  • Oracle versions 11g, 12c, 18c and 19c

  • SQL Server versions 2012, 2014, 2016, 2017, 2019 and 2022

  • H2 version 1.4 (not suitable for production environments)

Java

As a Java API, LuciadLightspeed requires a JDK for development and a JRE for deployment.

Table 1, “Supported Java versions” gives an overview of the supported Java versions.

Luciad aims to support the latest Java LTS version in its latest releases. The minimum JDK/JRE requirements never change with a minor upgrade (an upgrade from 2022.0 to 2022.1, for instance) or a patch release of LuciadLightspeed.

For users of Mac computers with Apple silicon

Even though you’re using an ARM-based processor, download and install a JDK for an x86 64-bit architecture instead of an ARM-based JDK.

We recommend using the latest version of any long-term support (LTS) release. At the time of writing, the LTS releases are Java 8, Java 11, and Java 17.

We haven’t encountered any provider-specific issues. LuciadLightspeed is regularly tested using OracleJDK, Adoptium Temurin, Liberica, and several other Java providers.

OpenJDK 8 considerations

LuciadLightspeed doesn’t officially support OpenJDK 8. The minimum supported version is OpenJDK 11 at the time of writing. We don’t test LuciadLightspeed on OpenJDK 8, but in practice, recent LuciadLightspeed versions seem to work fine on it.

JDK 11 and JDK 17 considerations

LuciadLightspeed supports JDK 11 and JDK 17 in compatibility mode. If you want to get rid of illegal access warnings or errors, use the --add-opens <module_name>/<package_name>=<reflectingmodule> flags. If you set the reflectingmodule value to ALL-UNNAMED, you allow all classes from the classpath to access the package.

In practice, any illegal access violation will come from these third-party libraries:

  • JIDE, used by Lucy’s tabbed interface front-end. This does not affect Lucy Map Centric.

  • JAI, used to:

    • Save models to GeoTIFF

    • Enable non-hardware-accelerated imaging operations

Supported JVM implementations

We support the HotSpot JVM.

Deployment

To deploy the LuciadFusion Platform, a Java servlet container / application server is necessary: Apache Tomcat, Oracle WebLogic, Glassfish, IBM WebSphere, JBoss, Jetty, and so on. For your convenience, the product is shipped with the Jetty 9.4.50 servlet container, so that the server can be used out-of-the-box. The supported versions of each servlet container / application server depend on the minimum supported Java Servlet and EE version:

For example, Java Servlet 3.1 / EE 7 is compatible with Apache Tomcat 8 or higher, while Jakarta Servlet 5.0 / EE 9 requires Tomcat 10 or higher.
