Java Runtime Environment

Installation Manager installs a Java™ Runtime Environment (JRE).Default location of the installed JRE folder:

• Windows: install_dir\IBM\Installation Manager\eclipse
• Linux, UNIX, and OS X: install_dir/IBM/InstallationManager/eclipse

To identify the version of the JRE used by a specific platform:

• In the installation kit for Installation Manager, open the install.ini file. The path for the JRE contains the JRE version.

Troubleshoot

You receive an error when the JRE cannot be found:

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Launcher. No Java virtual machine was found after searching the following locations:
install_dir/eclipse/jre_version/jre/bin/j9vm/jvm.dll

To fix:

• Verify the jre_version folder exists. If files are missing, we can reinstall Installation Manager,

• Check the location path to the JRE in the .ini files. To find files...
  find . -name \*.ini -exec grep -il jre {} \;

  For example, set jre_version path:

  -toolId
  install
  -accessRights
  admin
  -vm
  jre_version\jre\bin\j9vm\jvm.dll
  input @osgi.install.area\install.xml
  -vmargs
  -Xquickstart
  -Xgcpolicy:gencon
