Reports Server: REP-3000

Question

Hi all,
I have the following system setup:
OS: SuSE SLES-7 Linux
Kernel: 2.4.7-64GB-SMP
Memory: 1GB RAM
SWAP: 2GB
When I try to run the test report on the "Getting Started with Oracle9i Reports" I get the following error in a new Browser Window:
- Error
REP-3000: Internal error starting Oracle Toolkit.
REP-3000: Internal error starting Oracle Toolkit.
I don't want to use the standard X server. I decided to use Xvfb.
I performed the following steps:
- Shutdown of Oracle9iASr2, according to metalink note: 200475.1 (oracle)
- $ emctl stop
- $ webcachectl stop
- $ dcmctl shutdown
After that the 9iASr2 instance was sucessfully halted.
- Shutdown the standard X server which was running on display number 0 (root)
- Start Xfvb as root, according metalink note: 208745.1 (root)
- $ nohup /usr/bin/X11/Xvfb :50 -screen 0 1024x800x8 -pn -fp /usr/lib/X11/fonts/misc -sp /etc/X11/xserver/SecurityPolicy &
- $ DISPLAY=$(hostname):50.0; export DISPLAY
- $ /usr/X11R6/bin/xhost +
I also tested to execute the command xclock and I got no error.
- 9iASr2 config changes (oracle)
- Changed DISPLAY variable in .profile to the new value
- $ORACLE_HOME/bin/reports.sh
- DISPLAY=lindi:50; export DISPLAY
- $ORACLE_HOME/opmn/conf/opmn.xml
- <prop name="DISPLAY" value="localhost:50.0"/>
- This entry is in the OC4J_BI_Forms config tag. is that correct?
- Startup 9iASr2 (oracle)
- $ emctl start
- Connect to OEM and started the whole instance. All processed were sucessfull started
- I was able to connect to OEM, this means the Xvfb Frame Buffer is setup correctly otherwise I would not be able to connect to the EnterpriseManager. Is that correct?
- I was able to check the failed jobs in the reports server. That means the report server is running.
- I was able to run my forms application.
- I open the "Getting Started with Oracle9i Reports" page in a browser and got the error decribed above.
To me it seems that there has to be another DISPLAY variable I did not set correctly. Because when I start another X server with the user oracle on display 0 then I'm able to run the report sucessfully. But I don't want to start the standard X server, because then I need access to the console, and I not always have access to it.
Does anybody know what that could be and help me,
thanks
Oliver

Try the solution provided in the Release Notes Addendum section 5.10.15 (Component issues)
Anyway I am providing the notes here.
5.10.15 Reports in-process server gives REP-3000 error when running report
When running a sample report using the report in-process server, an error message
like the following can appear in the browser:
REP-3000: Internal error starting Oracle Toolkit.
REP-3000: Internal error starting Oracle Toolkit.
Use the following sample URL to test for this error message using the appropriate
hostname, domainname, port and two_task entries:
http://hostname.domainname:port/reports/rwservlet?report=test.rdf&userid=scott/t
iger@two_task&destype=cache&desformat=htmlcss
If the REP-3000 error message appears, the display is not set correctly. When
running a report server from the command line, the environment variable DISPLAY
setting is used. However, the reports in-process server uses the following
configuration file for the display setting:
$ORACLE_HOME/j2ee/OC4J_BI_Forms/config/oc4j.properties
The default display entry is as follows:
oracle.display=:0.0
On some servers, there might not be an X server running on :0.0 or this entry
might not be resolved correctly. In such cases, change the display setting to a
machine where an X server is present and can be accessed by this server.
To test whether an X server is running on given machine and you have permissions
to connect to it, you can use the following command:
xterm -display myserver:0.0
If you do not have permissions to access the display or if there is no such display
running on the given machine, an error similar to the following is displayed:
Xlib: connection to "myserver:0.0" refused by server
Xlib: Client is not authorized to connect to Server
xterm Xt error: Can't open display: myserver:0.0
Once you have identified a machine with a valid X server, or started the display on
the server machine being used, you can change the default entry to the new display.
For example to use the X server running on myserver:0.0 we would change the
default entry to:
oracle.display=myserver:0.0
After these changes are completed, it is necessary to restart the Forms/Reports oc4j
instance with the following commands:
$ cd $ORACLE_HOME/opmn/bin
$ ./opmnctl stopproc type=oc4j instancename=oc4j_bi_forms
$ ./opmnctl startproc type=oc4j instancename=oc4j_bi_forms
You can now test the sample URL again to make sure that the in-process server
works correctly. When using the sample URL, the sample test.rdf report should
be displayed in the browser.
