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 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.
Troubleshooting
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 -Xgcpolicy:gencon
