Java Runtime Environment
Installation Manager installs a Java Runtime Environment (JRE).
Default location of the installed JRE folder:
install_dir/IBM/InstallationManager/eclipse
To identify the version of JRE used by a specific platform, in the installation files 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_5.0.4.sr11\jre\bin\j9vm\jvm.dll
Verify the jre_5.0.4.sr11 folder exists. If files are missing, you can manually reinstall Installation Manager.
Check the path to the JRE in the .ini files. For example, install.ini contains:
-toolId install -accessRights admin -vm jre_5.0.4.sr11_20091106a\jre\bin\j9vm\jvm.dll -input @osgi.install.area\install.xml -vmargs -Xquickstart -Xgcpolicy:gencon
