Installing on Linux (Sun Java System Message Queue 4.2 Release Notes)

Sun Java System Message Queue 4.2 Release Notes

The following issues affect installation on the Linux Platform

On the JDK Selection panel, the scroll list displays only one item. This makes it difficult to select other JDK's in the list. (Bug 6584735)
If the JDK is current and the user selects “Install default JDK” on the JDK Selection Screen, the installer still tries to install it and reports that it cannot install the package. Installation completes successfully despite this issue. (Bug 6581310)
If the currently installed JDK is a later version than JDK 1.5.0_15 (the version normally installed by the Message Queue installer), then the Message Queue uninstaller cannot find the default IMQ_JAVAHOME directory and returns an error. (Bug 6673415)

Workaround: Install JDK 1.5 manually as follows before running the Message Queue uninstaller.

# cd installImage/Product/UNIX/LINUX/X86/2.4/Packages

# rpm -i --force jdk-1.5.0_15–linux-arch.rpm

where arch is either i586 or amd64.
When the installer is run in dry run mode (installer –n), the Summary Screen shows some error messages and also displays an install status of “Incomplete”. This is incorrect and misleading; a dry run does not install anything on the system; it only creates the answer file that can be subsequently used to perform a silent install. (Bug 6594351)
