If the emulator client applet loads but the emulator session does not connect, try the following:
ping 255.123.123.3
. myclient
,
type ping myclient
. nslookup w.x.y.z
, where w.x.y.z
is the dotted decimal address of the host. If the client is given a numeric address, it
contacts the local DNS to get the host name. Sometimes the DNS is not set up properly for
this reverse look-up. If the DNS is not setup properly, add the host name and address to
the HOSTS
file on the client.
Did the Alternate Terminal interface fail to work with the emulator client?
If you are using an old HTML file from a previous release, the Alternate Terminal interface may not come up or a Null Pointer exception message may be displayed when starting a session. If this happens, you may need to edit the HTML file, and replace any occurences of scbase.jar or scbase.cab and scfull.jar or scfull.cab with sccbase.jar or sccbase.cab.
Are you having trouble connecting to the host when using file transfer on a 5250 emulator session, using the HODCached applet, or loading the Database On-Demand applet?If you are using file transfer on a 5250 emulator session, using the HODCached applet, or loading the Database On-Demand applet and having host connection problems, check to see if you have a classes.zip entry in your CLASSPATH. If so, remove it but be aware that other programs may require this classpath entry.
Are the remapped Alt-key combinations not working as expected?The JVM in Internet Explorer handles key events differently according to its level. Remapped Alt-key combination key events are sometimes sent to the menu even after the action for the remapped key is taken. The result is that focus is put onto the menu and remains there. To regain focus, click on the active screen.
To avoid this, try using JVM levels 3167 and later.
On a Linux or AIX machine, is the Meta modifier being processed with the Alt modifier when remapping key combinations?On AIX and Linux, depending on the keyboard assignments for the machine and the level of Java installed on the machine, the Meta modifier might be processed with the Alt key. Thus, if you press the Alt key on these systems, you receive Meta-Alt key events. This causes problems if your Host On-Demand session is defined on Windows, a key remap assignment is done using the Alt key, and you start the session on a Linux or AIX client.
For example, the administrator defines a session using the Deployment Wizard on Windows. In this session, the administrator maps the Reset key function to the Alt-R key combination. If a user starts the Host On-Demand client on a Linux or AIX machine that processes Meta-Alt for the Alt key, they will not be able to process the Reset key function correctly. Every time that they enter the Alt-R key combination, Host On-Demand receives a Meta-Alt-R key event, which will not process the Reset function.
To fix this, the administrator of the AIX or Linux machine must use the xmodmap
command to change
the keyboard assignments so that Alt is processed without the Meta modifier. Note that the
xmodmap
command affects the current X window session, so logging out restores the key
assignments to their original values.
A specific example for AIX follows:
The 1.1.5 JDK shipped under Netscape processes Meta-Alt for the left Alt key if the keysym for the right Alt Key is not assigned to mod1.
When using a non en_US.8859-1 keyboard, the Xserver may have the right Alt key, Alt_R, mapped to Mode_switch (or a key besides Alt_R). Additionally, mod1 may have the left Alt key, Alt_L, solely assigned. When mod1 only has Alt_L assigned, and this key is pressed, Meta+Alt is generated. To avoid the Meta modifier from being added to the key event, the Alt_R key must be added to mod1. To accomplish this, do the following (written in pseudocode):
xmodmap if ((mod1 = Alt_L) and (mod2 = Mode_switch, Mode_switch)) xmodmap -pke if (keycode 70 = Mode_switch) xmodmap -e "add mod1=Mode_switch"Are the browser, Host On-Demand session, and the Linux X-window system unresponsive?
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.
Did the URL display errors under Netscape 4.x on Chinese-Traditional Windows platforms?If you are using Netscape 4.x on a Chinese-Traditional (Taiwan) Windows platform, URLs that are displayed on 3270 and 5250 session screens may be truncated and overlap with text on the same row. Try upgrading to Netcape Version 6 or later.
Did the F10 key fail to function in Host On-Demand with Netscape on the UNIX platform?The Unix version of Netscape is built on the Motif toolkit, which binds the F10 key to a command that activates the menu bar by default. As a result, the terminal emulation screen of Host On-Demand running on Unix versions of Netscape cannot handle the F10 keystroke.
There are two workarounds:
While using Netscape 4.x, transferring large UNICODE UTF-8 files to a host may cause the emulation session to hang. Try upgrading to Netscape Version 6 or later.
Are Database On-Demand and the 5250 File Transfer functions not able to connect to a V5R1 iSeries host?If the Database On-Demand and the 5250 File Transfer functions of Host On-Demand are not able to connect to a V5R1 iSeries host that has long password support enabled in a Netscape 4.x browser, try upgrading your browser.
Did Simplified Chinese characters display incorrectly when using Red Flag Linux 3.0?If Simplified Chinese characters do not display correctly, your Java plug-in may not support the correct font properties file (font.properties.zh). Try installing a different Java 2 plug-in.
Did Simplified Chinese characters display as square symbols?On the Windows 2000 Simplified Chinese platform, double-byte characters are displayed as square symbols in Netscape 6 and Internet Explorer 6. To display these characters correctly, try installing the Sun 1.4 Java plug-in or the IBM 1.3.1 Java plug-in.
Are you having trouble typing in text fields?When using Host On-Demand with Java 1.4.0, you may lose focus when making a selection in a choice box, and you will not be able to type in text fields. To regain focus, you may either click off of Host On-Demand into another application, your desktop, or another location, and click back, or you can minimize and then maximize the Host On-Demand panel. Try using Java Version 1.4.1.
