Setting up Java

Java Runtime Environment (JRE) is essential for the proper functioning of the Fiorano Platform. For operating systems and environments with high activity, follow the procedure below to setup the JRE.

Requirements

Though JRE is sufficient for general use, a Java Development Kit (JDK) is required to build custom Java components.

Download and Install JDK

For the servers to run, JAVA1.8 Java Development Kit needs to be configured. Download and install from any of the following download links which include Oracle Java and some open JDK builds:

Set Java Home

Choose the 32-bit version or the 64-bit version depending on the architecture of the machine on which the server is located.

A 32-bit JDK can be used with 64-bit architecture, while a 64-bit JVM is highly recommended in production environments where the servers require more memory.

Configuration

Once the installation is complete, the changes below need to be executed in the Fiorano Environment to use the installed JDK.

Servers

Open the fiorano_vars.bat(sh) file from FIORANO_HOME.
Point the variable JAVA_HOME and JDK_HOME to the location where Java is installed.

Example

SET JAVA_HOME=C:\Fiorano\12.2.0\jre1.8.0_231_64

eStudio

Open the file FIORANO_HOME/eStudio/eStudio.ini
Specify the location of JAVA_HOME/bin after the line -vm

The settings present in the fiorano_vars.bat/sh file are used for servers and components as default settings. To use a separate JDK for components, change the JVM_PARAMS value present in Runtime Arguments tab under Properties.

32-bit or 64-bit eStudio launchers may be used depending on the JVM used in the system.
