Java: JDK 1.8

Apache Tomcat 8+

MySQL 5.1 - 5.6 or Oracle 11g or 12c for the internal registration database, and theoretically any JDBC-compatible DBMS for the configured upstream connection

Java: JRE 1.6 - 1.8 (needed when using MarvinSketch applet in all browsers, and in Internet Explorer 11 also for the file uploads)

ChemDraw 14 or above has to be installed locally (which installs the browser plugins) if chosen as a structure editor

Depends mainly on the database size

At least 2-4 cores are recommended

4-8 GB RAM or more, at least 3 GB should be provided explicitly for the Tomcat JVM.

Cca 500 MB disk space for the application, additional 1 GB during deployment for temporary files; data storage disk space requirements highly depend on the number of structures, approximately 5 GB / 1 M structures

Standard office hardware that can run Java applets and a modern browser with JavaScript support with a decent performance

At least 4 GB RAM suggested if large (> 10000 structures) SD files are processed during bulk upload

Recommended minimum display resolution 1366x768
