If you are getting a segmentation error when trying to launch the Host On-Demand applet using a Netscape 4.x browser on a Linux machine with the 2.4 kernel, upgrade your browser to either Netscape 7.x or Mozilla on Linux with a Java 2 JRE.
If you install and start Host On-Demand and then reboot your machine, Host On-Demand may not automatically start back as expected. This is because the Service Manager may not be running. To verify if the Host On-Demand Service Manager is running on your server, issue the following command:
netstat -na | grep 8999You should see an output as follows:
tcp 0 0 0.0.0.0:8999 0.0.0.0:* LISTEN
If you fail to see port 8999 listening on your server, start the Host On-Demand Service Manager manually by executing the appropriate NCServiceManager script file. For Host On-Demand V8, this file is located in the HostOnDemand/lib/samples/NCServiceManager directory on your Host On-Demand server. For previous versions of Host On-Demand, this file is located in the hostondemand/lib/samples/CommandFiles directory.
You may notice that Host On-Demand dialogs do not display completely when using a Linux client with a KDE (K Desktop Environment) desktop. Try changing to the Gnome desktop or using the IBM Java 2 plug-in.
This problem occurs under Red Hat Linux and Netscape 6 (or later) with the IBM Java runtime environment (JRE) or the IBM JDK for Linux, Service Release 8 and below. When an empty pull-down menu or choice list is clicked (that is, when the leftmost object on the Macro Manager Toolbar has no macros present to choose from), the browser, Host On-Demand session, and the Linux X-windowing system become unresponsive.
You can avoid this problem by not clicking the empty pull-down menu, or clicking the pull-down menu only when there is at least one item to select. However, if the Linux X-window system becomes unresponsive after clicking the empty pull-down menu, restarting the X-window system returns control back to normal (without having to reboot the entire machine).
Try upgrading to the IBM Linux JDK, Service Release 9 or above. You can download this from IBM DeveloperWorks at http://www-106.ibm.com/developerworks/java/jdk/index.html. New users need to register before downloading it.
If DBCS characters become square boxes when using Windows or Red Hat Version 8.0 client operating systems, try using IBM JRE V1.3.1 or later.
