Graphic card required to generate oracle PDF report.

Hi there,

We have the Oracle E-business Suite 11.5.9 running the HPUX box for the customer. When the customer need to generate the application PDF report, there will be an error message until they put one additional graphic card to the server. There is another develpement server without the graphic card. Therefore, it can't generatethe PDF report.

Anyone had encountered this before? Any special display settings need to be configured without installing the additional graphic card?

Thanks in advance,
kenken

Re: Graphic card required to generate oracle PDF report.

Do you need a graphics card or just xwindows DISPLAY set?

If it's not Top Secret, what is this error
message?

> Anyone had encountered this before?

It might be easier to say, if you also
disclosed exactly how "the customer" tries to
"generate the application PDF report".

Showing actual commands and their actual
output is often more helpful than vague
descriptions of both.

It's hard (for me) to imagine why you would
need _any_ graphics card to produce a PDF
report, let alone two of them.

Re: Graphic card required to generate oracle PDF report.

You need to have exceed or reflection X installed on the PC and then need to export the display from server to this PC's IP.

export DISPLAY=IP of PC:0.0

Thanks

Re: Graphic card required to generate oracle PDF report.

hi Kenken,

X Virtual Frame Buffer should solve the problem. Search for XVFB.

if you need any further assistance, please let us know.

We use it here for Oracle Reports and it works fine.

Use the following command to check if it is already installed on your system:
swlist -l file |grep -i Xvfb

kind regards

Re: Graphic card required to generate oracle PDF report.

Hi Guys,

Thanks for all the information and help.

The current system is managed by the customer and we are going to help out on the migration. I have to ask the customer to provide me all the details every time.

I had asked the exact error message they got when they tried to generate the PDF report from the oracle application. It just a simple error message like the report can't be generated. However, when they installed a graphic card, the problem was just gone.

That is why I am asking what is the possibility and whether there is any alternative.

thanks.

Re: Graphic card required to generate oracle PDF report.

hi Kenken,

xvfb is a software alternative to the graphics card.

You can either install this on the server which does not have the graphics card.

Alternative, you can export the DISPLAY environment variable on the server which does not have the graphics card to the server which has the graphics card.

e.g.

[on Server 1 which does not have a graphics card]
export DISPLAY=server2:0

There might be some specific configuration files that need to be modified at the Oracle E-business Suite level. For more assistance, I would suggest that you create a Service Request with Oracle Support.

good luck!

kind regards
yogeeraj

Re: Graphic card required to generate oracle PDF report.

I think we are using Xvfb for something similar with Oracle Financials.

Note that to save memory you can normally drop the virtual desktops dimensions and colour depth.

We use the following, (run by the oracle Unix user):

nohup Xvfb :53 -screen 0 6x6x8 -pn -fp /usr/lib/X11/fonts/misc -sp $HOME/SecurityPolicy >> Xsession.log 2>&1 &

(all as one command without the line break)

Re: Graphic card required to generate oracle PDF report.

Thanks Yogeeraj,

I have instaleld the patch PHSS_34392 for the HP-UX 11.11 box, but I think there are additional steps need to configure before it can be used.

May I know how to configure it or where is the doc? I can't find it from the itrc.

Re: Graphic card required to generate oracle PDF report.

Anyone can help? I have installed patch PHSS_34392 one more time, but couldn't find the /etc/rc.config.d/xvfb.conf file and /sbin/init.d/xvfb this time?

any additional patch need to be installed?

thanks

Re: Graphic card required to generate oracle PDF report.

Does your app really need a running X session to generate reports, or is it just some silly Java app that needs you to set java.awt.headless=true on the JVM?

Re: Graphic card required to generate oracle PDF report.

I think the startup scripts may not have been included with the patch, later versions of X included xvfb support as an xserver extension.

I suggest you either create your own, email me or the other poster (see my profile) or contact HP support for a copy.

Alternatives : use an X emulation package eg Reflections X and set the DISPLAY variable accordingly prior to running the oracle report, ensuring the Xsession is running.

Re: Graphic card required to generate oracle PDF report.

Hi Heironimus,

The oracle application need the physcial graphic card or the XVFB Xserver running. Both are working well for the application.

However, my current problem is I can't see the /sbin/init.d/xvfb file and /etc/rc.config.d/xvfb.conf after I installed the latest patch PHSS_34392, but I can't see those files.

Hi There,

I really need to solve this problem. Anyone knows any additional patch I need to apply so that I can see those xvfb related files.

Thanks a lot,

Re: Graphic card required to generate oracle PDF report.

Kenken. You do not need those two files you refer to. We have neither of them and are using Xvfb in what looks to be the same way as you want to as referenced in my post further up your thread.

I've attached the SecurityPolicy file the command I gave earlier refers too, copy it into the directory as indicated by the command as SecurityPolicy. Then change the :53 in the command to whatever screen number your application is configured to use and execute the command as the user who will be using the Xvfb instance (i.e. the Oracle Application user) not root.

I installed VNC server instead of xvfb and it works fine.

Thank you very much for your inputs.
