Hi Managers,
Thanks for your replies! Specials thanks to Murtaza Talawala, Anthony A. D.

QUESTION :
I need to run the command "xhost +" on the console at each startup of the
system (TRU64 5.0A).
Can you tell me how I can automate this?
ANSWERS :
1) Some of you pointed out that "xhost +" is a very insecure command. In
fact, I discovered that I can limit this to the server itself : I need only
to type "xhost + gnvasofi" (where gnvasofi is the server itself) to be able
to print bitmap reports from Oracle Financials.
2) Put it in /etc/profile : I have tried but it did not work (maybe I did it
wrong)...
You can either put it in /etc/profile file. So that every time the system
comes up the same gets executed globally for all accounts.
3) Create a file in /sbin/rc3.d : it does not seem to work either...
you can go to /sbin/rc3.d/
create file with name <as I suggest> S??hosts ( note ?? should be the
highest no. in side this directory) and put in side it ( xhost + )
then #chmod 744 S??hosts
CONCLUSION :
I think that Jim is right when he wrote:
I don't know how to do what you want since xhost does not obey a '-display'
command-line argument to do it. Maybe that is a good thing.
Maybe it will obey the DISPLAY environment variable?
My conclusion is that it cannot be automated. At each startup of the server,
I need to log in on the console itself as root and issue manually the
command "xhost + gnvasofi". As it is not very convenient, I will look now at
another solution as described in Oracle Metalink note 181244.1 titled
"Configuring an X Display Server for Applications on Unix Platforms" and try
to use the software alternative XVFB (X Virtual Frame Buffer) or XVNC
(X-based VNC) instead.
Thank you and best regards,

PS : For those of you who are interested, this is the Note from Oracle
Support concerning the problem of running bitmap report with Developer 6i
Patchset 5 and above :
* fact: Oracle Application Object Library 11.5
* fact: Sun SPARC Solaris
* symptom: Error when running bitmap report
* symptom: REP-3000: Internal error starting Oracle Toolkit.
* change: Applied Developer 6i Patchset
* cause: The environment variable DISPLAY has not been set correctly
fix:
The DISPLAY variable needs to point to an IP address where an active X Sever
process resides, preferably on the same server where the concurrent manager
reside or an external server or PC; otherwise, bitmap request processing
will encounter a REP-3000 error message.
Set the DISPAY environment variable on the server where the concurrent
manager
resides:
1. Login into Unix as the privileged Oracle Application user, typically
applmgr.
2. Determine the server's IP address, type: cat /etc/hosts
3. Set the DISPLAY environment variable at the command line:
DISPLAY=<IP_Adress>:0.0 ; export DISPLAY
4. Verify that xwindow is installed and/or properly configured on the
server:
a. Change the default directory to the directory where xwindow
executables
resides. For Sun Solaris, typically, its /usr/openwin/bin or
/usr/X11/bin.
b. Execute the xwindow server authentication command: xhost +
c. Execute a simple xwindow program like xclock in the background: xclock
&
d. Verify at the server's console that xclock is displayed.
5. Edit either the adcmctl.sh concurrent manager startup script or the
APPL_TOP environment file referenced by the adcmctl.sh script.
Enter the following two commands:
DISPLAY=<IP_Adress>:0.0 ; export DISPLAY
/usr/openwin/bin/xhost + (or equivalent path)
6. Restart the concurrent manager.
Note: In Developer 6i patch 5, development addressed several bugs regarding
image display and resolution. As a result, the operating system environment
variable DISPLAY is required to be set to a valid X Display on non-Windows
platforms. It provides a fundamental capability that Reports requires for
font
metrics and rasterization, image manipulation and conversion, etc.
