Problem in reflection software setup...Need help..
nirav
My pc crashed and the systems guys reinstalled all existing softwares
-including reflection. I am a dba and I used to connect to the oracle
server using reflection.
Earlier I was able to connect to host as a virtual terminal and also
through reflection x manager window (this gives a graphical display
that we need during installation etc -for general work the Virtual
Terminal is enough)
Now after the revised install I only have a virtual terminal and not
the refletion x manager window at all! I tell this to our system people
but they can not seem to figure out what is the probem!
This exact problem had occured a year ago, when I joined this company
and a guy who finally solved this wrote as a note:
"Installing the X server and the appropriate libraries for WRQ
Reflection on your machine allowed us to invoke X without any issues"
This guy has left company and we do not know what to do. Can you pl.
help?? This is urgent.
With thanks,
Nirav

No idea how Reflection works...
The X-client program/process runs on the server. E.g. OEM, dcba,
x-term, x-eyes, etc. It uses the -display setting to stream its graphic
display calls to a X-server. The X-Server runs on the client PC. It
manages one or more displays. It accepts the X data stream from the
X-client and renders it. Any keyboard & mouse interaction is send by
the X-Server to the X-client.
One reason why the X-Server will not accept a connection from a
X-client is when it uses X-authority. The X-Server creates a unique
hash for the display and the X-client is required to send that hash
with its data - else the X-server will not allow it to connect. The
Unix xauth command is used for listing the xuath hash of the server,
and the same command is used to add the hash at the X-client's side.
Another reason is that the X-server is not running - or the display
number used byu the X-client is not a valid display handled by the
X-Server.
Keep in mind though that the X-server runs on the client platform and
the X-client is in fact a server platform process.
X is however slow and clunky. And Y is not really supported... I
suggest that you get VNC instead. Much easier and a lot more
flexibility as the displays are persistant (the display resides
virtually on the server and not on the X-server as is the case with X -
where loosing the client platform means loosing the X-desktop).
VNC Server is available for most platforms (Windows, Solaris, HP-UX,
Linux. OS/X. etc). You install it on the server platform, run the
vncserver Perl script that creates a display for you. Then you use VNC
client (from any platform at any time) to connect to that VNC server
display. E.g. you connect from your office Windows desktop to the
Oracle server's VNC desktop, and start to vi listener.ora. You leave
for home and at home dial into the office network, use VNC client on
your home PC and continue with your vi session.
Even simpler is using Linux. To be honest, any Oracle DBA that has to
support multiple Unix Oracle server and is not using a Unix-based
desktop client (like Linux)... raises a lot of questions in my mind as
to how effectively that DBA can administer those servers.
With Linux it is even simpler as you can use ssh's reverse X-tunnel to
tunnel X-client calls back to your desktop and display it on your
desktop. And VNC is starndard on Linux too.

hpuxrac
unix client and the x server part. Each of these has a separate
install disk.
There are some incompatibilities with the different versions at times.
I have the 11.0 hpux unix client installed along with the 12.0 x server
software.
For this combination I had to have them installed into different
directories. The 11.0 versions of both of these products can
apparently both be installed into the same directory.
There are newer versions of both I am sure.

Nirav did you get your problem fixed?

Since the reflections can either look exactly like .dtprofile _or_ be
locally managed and not be as impactful on the unix host, and I do most
everything on the hosts in X-windows anyways, and OEM runs the same
(now that I'm a big enough W2K box), I don't get this at all. And I
consider myself quite the unix bigot.

Billy apparently doesn't use Reflection and he noted that at the
beginning of his post. Not sure why he answered ( or maybe deflected
)the post originally since his answer did not have any info about the
question posted by the OP.
