To resolve this problem, install the
required 32-bit Linux package from
the Linux install disk or package
repository.
Note: For a partial list of 32-bit Linux packages that are prerequisites for running
Developer for System z® on
a supported 64-bit Linux operating
system, see IBM® Rational® Developer for System z Version 8.0.3: Installation Guide.
- Operating systems:
- Red Hat Enterprise Linux V5 or V6 64-bit
- SUSE Linux Enterprise
V10 or V11 64-bit
- Problem:
- When a perspective is opened for the first
time in a new work area, the Welcome page of the perspective is blank
and an error message is displayed when the Welcome tab is closed.
- Symptoms:
- The Welcome page of the perspective is
blank, as described above.
- When the Welcome tab is closed a Problem Occurred error
window opens with the following error message:
Unhandled event loop exception
No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
- When this window is closed an Internal Error window
opens with the following error message:
An SWT error has occurred.
You are recommended to exit the workbench.
- Analysis:
- The Welcome page requires 32-bit versions
of the Linux operating system
libraries. Some of these libraries are not installed by default when the Linux 64-bit
operating system is installed.
- Resolution:
- To resolve the problem:
- Install the required 32-bit package from
the Linux install disk or package
repository:
Table 1. Required 32-bit package Operating system: |
32-bit package: |
Red Hat Enterprise Linux V5 or V6 64-bit |
xulrunner.i686 |
SUSE Linux Enterprise
V10 64-bit |
mozilla-xulrunner-32bit |
SUSE Linux Enterprise
V11 64-bit |
mozilla-xulrunner190-32bit |
For example:
- For Red Hat Enterprise Linux V5 or V6 64-bit, enter the following
command on the command line of a terminal window:
yum install xulrunner.i686
- For SUSE Linux Enterprise
V10 64-bit, enter:
zypper install mozilla-xulrunner-32bit
- For SUSE Linux Enterprise
V11 64-bit, enter:
zypper install mozilla-xulrunner190-32bit
- Close and reopen Rational Developer
for System z.
The Welcome pages should now work properly.
