Changing the JDK for a Grid Node

If a grid is installed using a particular JDK version (see the Infor ION Grid Installation Guide) and you later want to change to another JDK version, you may do that by configuring a grid property. As always with grid properties, they may be configured and overridden in different contexts (see Grid properties). Typically a change of JDK version will be done on all hosts in a grid or on individual hosts of a grid. This documentation describes how to change the JDK version for all nodes running in one host. If you want to change the JDK version for all hosts, you repeat the procedure for each host.

To change the JDK for a grid node

  1. Navigate to the Configuration Manager.
  2. On the Configuration Manager page, click Grid Configuration.
  3. Click Grid Properties.
  4. In the Property column list, click Java Executable in the Misc. Node Properties section.
  5. In the matrix, locate the column for the host whose JDK you want to change and click on the property value link for that column in the Grid-Wide row (first row).
  6. Log in if necessary.
  7. In the dialog box, enter the absolute path to the Java executable of the new JDK version (for example, C:/JDK1.7/bin/java.exe).
  8. Click the Save button to close the dialog box and save your changes.
  9. Persist the configuration changes by clicking the Save button in the upper left corner of the Configuration Manager.
  10. Repeat this procedure for other hosts whose JDK you want to change.
  11. For any nodes currently running, you will need to restart them to apply the changes. Any new nodes will use the new JDK when they are started.
