The installer first extracts the bundled JVM into a temporary area and then uses it to launch itself. If for some reason, the JVM crashes, you can still run the installer using another JVM, preferably JVM 1.5.0 or higher. The syntax is:
Product releases that differ in either Major or Minor numbers will be a separate installation, and will not recognize the old installation. In this case, 5.0 is a major release and hence will not recognize either 3.x or 4.x product installations.
The installer on UNIX must open an additional window, generally for graphics. It uses the DISPLAY environment variable to specify on what computer to open the window. If the environment variable is not set, the installer will either wait or abort after displaying:
The DISPLAY variable must be set to the IP address or name of the computer (on which the installer graphics window are to be displayed), followed by a screen address, which can be
:0.0 . For example:
For example, consider a scenario where you need to install the adapter on a remote HPUX machine (named
itaska). Because you have a Solaris 5.6 machine (named
alaska) that has a video card and monitor installed, you can run an X-window application on it. You decide to telnet to
itaska from
alaska.
When you telnet to itaska, you will not have access to
itaska's monitor and will be unable to display an X-window application. That is why you must set the
DISPLAY variable, which instructs the X-server to redirect all windows to the computer set in the variable. Before doing so, the computer (specified in the
DISPLAY variable) must give the permissions to share its monitor.
If the original uninstall directory is in use at uninstall time, it cannot be removed by the installer program. The installer then creates a second uninstall directory for the second installation. To remove the second installation, you must invoke the uninstall program from the second uninstall directory. The original uninstall directory can also be manually removed, if empty.
