Changing the bit mode of Installation Manager

IBM® Installation Manager is available in a 64-bit version for specific platforms.

Before you begin

For installed packages, check the documentation for each package to verify that the bit version of Installation Manager that you are using is supported. Some packages work only with the 32-bit version of Installation Manager. Review the system requirements information to determine the platforms that are supported for 32-bit and 64-bit modes, see System Requirements for IBM Installation Manager.

About this task

You can use the -reinstallIM option to replace the 32-bit version of Installation Manager with the 64-bit version. On Windows, if the 32-bit installation is in the Program Files (x86) default location, the install location changes to Program Files directory.

Procedure

  1. Verify that the bit mode of the installation files is different from the bit mode of the installed instance of Installation Manager.
    1. Open the config.ini file in the configuration directory. The configuration directory is available in both the installation files directory and the installation directory for Installation Manager.
    2. Locate the osgi.arch=architecture entry that provides information about the operating system. The architecture variable indicates the architecture of the operating system.
    Information about the bit mode is available also in Installation Manager log files and in the information about installed packages:
    • The log file for the installation or update of Installation Manager contains an information entry that indicates the bit mode. The message in the entry has this format: osgi.os:operating_system, osgi.arch:architecture, bit_mode. For information about opening the log file, see one of these topics:

      If you do not see information entries, verify that the information option is selected. See Viewing log files by using wizard mode.

    • For 64-bit operating systems only, information about the bit mode is available in the installed.xml file. To open the installed.xml file directly, see Agent data location for the file location.
  2. Use the -reinstallIM option to install Installation Manager for a different bit mode.
