How to change the JRE of a node?

The Axway Decision Insight (DI) installer is delivered with an embedded JRE. When DI is installed on a node, the JRE is automatically updated along with the DI updates.

How to use your own JRE?

If you would like to use your own JRE, make sure it matches the following requirements:

  • OpenJDK 11 64-bit
    • Tip: You can download and then install from jdk.java.net.

On a clustered deployment, follow these steps for all the nodes in your deployment:

  1. To set your JRE, update:
    • The <install directory>/conf/path.conf file.
    • The JRE_DIR to your own JRE directory.
  2. Ensure than both the  <Decision Insight administration account> and  the  <Decision Insight execution account>  accounts are authorized to run a java program using your JRE.

Example:

conf/path.conf
JRE_DIR=/opt/jdk-11.0.1

How to use the embedded JRE?

For Windows installation

Update the file <install directory>\conf\path.conf and set JRE_DIR like this:

conf/path.conf
JRE_DIR=!PRODUCT_DIR!\lib\jre

If the node was installed as a service, the configuration must be updated for the changes to the JRE to be taken into account. The procedure is described in Install a node on Windows as a service


For Linux installation

Update the file <install directory>/conf/path.conf and set JRE_DIR like this:

conf/path.conf
JRE_DIR="$PRODUCT_DIR/lib/jre"
