Java Runtime Environment

Installation Manager installs a Java™ Runtime Environment (JRE).
Starting in version 1.4.1, a later version of the Java Runtime Environment (JRE) is installed for improved compatibility with Microsoft® Windows® 7.
Table 1.
Installation Manager version JRE version
1.4.1 and later jre_5.0.4.sr11_20091106a
1.4 jre_5.0.3.sr8a_20080811b
JRE default directory location:
  • Windows: <install_dir>\IBM\Installation Manager\eclipse\jre_5.0.4.sr11_20091106a
  • Linux® or UNIX®: <install_dir>/IBM/InstallationManager/eclipse/jre_5.0.4.sr11_20091106a

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_5.0.4.sr11_20091106a\jre\bin\j9vm\jvm.dll
  • Verify the jre_5.0.4.sr11_20091106a folder exists. If files are missing, you can reinstall Installation Manager. See Manually reinstalling 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
