Java Runtime Environment

Default location of the installed JRE folder:

• Windows: install_dir\IBM\Installation Manager\eclipse
• Linux, UNIX, and the OS X operating system: 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.

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

• Verify the jre_version folder exists. If files are missing, you can reinstall Installation Manager, see Reinstalling Installation Manager in wizard mode.
• Check the path to the JRE in the .ini files. For example, the install.ini file contains:

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