HP Caliper Linux Release Notes

2 Known Problems and Workarounds
GUI Limitations
• Using the same HP Caliper GUI project for both HP-UX and Linux sometimes
results in corruption of the project. When this occurs, the GUI will post an error
message at the end of a collection run saying it failed to save the information to
the project. This limitation can be avoided by using separate workspaces for HP-UX
and Linux.
• Running the GUI in native mode (that is, on an Integrity server by means of
caliper -g) can be problematic if the remote system the GUI is displayed on is
not on the same LAN as the server. The most common problems seen are poor
responsiveness and no indication of when a data collection run completes. A
workaround is to run the GUI in client mode (that is, on the remote system). See
/opt/caliper/gui_clients/README for details.
• When you try to bring up the GUI's help, you might get the following error if your
browser configuration is not set correctly:
Network Error (tcp_error)
A communication error occurred: "Connection refused"
The Web Server may be down, too busy, or experiencing other problems
preventing it from responding to requests. You may wish to try again at a
later time.
The problem is due to using a proxy and not excluding the localhost. The solution
is to add 127.0.0.1 to the proxy exclusion list in your browser's preference
settings.
• When you are using an HP Caliper GUI client on a desktop system and the
connection with the Integrity server is severed, the HP Caliper process on the
server might not terminate automatically. If this happens, you need to manually
kill the caliper process.
• Running caliper -g and displaying the GUI remotely over slow network lines
(such as DSL connections) can result in the GUI not receiving notification of the
completion of data collection. This results in the GUI behaving as though it is still
collecting data, even though the measurement has completed. This problem is due
to a bug in the interaction of Eclipse and Xt.
A workaround is to use a GUI client on the desktop system. For details on installing
a client, see the README file in the gui_clients subdirectory of the HP Caliper
home directory. (The default HP Caliper home directory is /opt/caliper.)
Known Problems
• HP Caliper will report an incorrect number of samples (more samples than should
actually occur) on Linux Integrity systems with a common firmware defect. A
