Are you using loadbalancing or SSL ? Did this ever work before ? If so, what has changed ? How are you determining you are on the second apps node ? What are the client and browser versions ?

Unable to launch forms after fresh installation of 12.1.1

Hi,
I have installed fresh production installation of Oracle Applications 12.1.1 on my laptop using oracle virtual box. Everything is working fine, i am able to connect to the URL from my host machine i.e Windows 7 with IE 8 browser. Able to login and navigate through HTML pages. However, when i try to launch forms , it has downloaded the java plug in and then IE crashes saying Internet explorer has stopped working. I could not find any error messages. It also says that "Applet oracle/apps/fnd/formsClient/FormsLauncher inited".
Need help to resolve this.
Thanks .

Hi Hussein,
Are you using any VPN/Proxy?
-- No , I have configured my windows 7 (Host Machine) to connect to oracle by adding the ip address and host.domain details in c:/windows/system32/drivers/etc/hosts file.
-- Made the ip address of the linux machine in virtual box as static
-- Disabled the firewalll in the linux machine.
Can you reproduce the issue with any other browser (Firefox) and see if it works?
-- I have tried to open the forms in mozilla firefox. However, it always prompts me to download the sun java plug in and never launches the forms.
Can you find any errors in the application.log file?

Unable to run forms in oracle forms developer 10g

I am using oracle forms developer 10g on oracle application Release 12.
When i run form i am getting error that weblistener is not running on default port 8888. Then i changed it to 8000. But still i am not able to run the forms.

Nivas,
In addition to running OC4J, you must also have your browser configured to use a Java Runtime Environment. The easiest - and preferred - method is to install the Oracle JInitiator as there is not configuration needed other than the installation. You can also use Sun's JRE, but you would have to research how to configure your PC correctly. The other option is to change your FormsWeb.cfg file to use the Browser Native JRE. Edit the formsweb.cfg file and find the IE= directive. The Default is IE=jinitiator. Change this to IE=Native, save your changes and you are done. This is not the preferred solution, but it does work.

Unable to launch any of Oracle apps!

I installed Oracle 8.1.7 on Red Hat Linux 7.2.
But I can't launch neither oemapp dbastudio nor dbassist.
But before install I've replaced Oracle jre in oracle.swd.jre
with BlackDown jre 1.1.8 because of some problems.
Help me please with this problem. Thank You.
"From Russia with love" 007

Hi
Please post this question in [The specified item was not found.|Portal Implementation] section.
Any how it seems to be the issue with the JAVA version compatibility. You must had installed new components which were build on higher version of java where as your JRE (java run time environment) is at lower version.

Unable to open forms when Launching another application on same browser.

Hi,
I have a server with configuration Oracle EBS 12.1.1 on RHEL 5.5, Database 11.1.0.7. On client machine we use Internet explorer, Firefox and Chrome to access the EBS and forms.
We are able to open the forms from all browsers, but problem arise when we access another application on same browser, resulting in not opening of oracle forms.
This is a java application using the same database on the server. This application works fine but Our Oracle Forms has to face the problems.
When we try to launch the forms, it results in FRM-92101 error. I read the MOS documents for
R12: "FRM-92101:There was a failure in the Forms Server during startup" Error When Attempting to Launch Forms [ID 454427.1]
Then I checked the application log file, it says that:
13/08/12 18:47:41.891 formsweb: Forms session <207> failed during startup: no response from runtime process
13/08/12 18:50:43.704 formsweb: Forms session <209> aborted: runtime process failed during startup with errors
Unable to switch to Working Directory: /oracle/TEST/apps/tech_st/10.1.3/forms
When I further investigate I found there is no such "forms" directory under "/oracle/TEST/apps/tech_st/10.1.3".
Then I read Oracle Notes:
FRM-92101 : Unable To Switch To Working Directory. (Doc ID 1434888.1)
FRM-92101 Error in Application.log: Unable to Switch to Working Directory (Doc ID 432708.1)
But no luck with all these. Please suggest something. Can't open both application simultaneously on same browser.
Regards,
Prashant Namdeo

Hi,
Please state whether the application was working fine before.
Please provide log file of:
--$LOG_HOMEora/10.1.3/j2ee/forms/forms_default_group_1/application.log
--DB alert logfile --check whether you can find any valuable information.
Please have a look at the following MOS notes:

Frm-40505:ORACLE error: unable to perform query in oracle forms 10g

Hi,
I get error frm-40505:ORACLE error: unable to perform query on oracle form in 10g environment, but the same form works properly in 6i.
Please let me know what do i need to do to correct this problem.
Regards,
Priya

Hi everyone,
I have block created on view V_LE_USID_1L (which gives the error frm-40505) . We don't need any updation on this block, so the property 'updateallowed' is set to 'NO'.
To fix this error I modified 'Keymode' property, set it to 'updatable' from 'automatic'. This change solved the problem with frm-40505 but it leads one more problem.
The datablock v_le_usid_1l allows user to enter the text (i.e. updated the field), when the data is saved, no message is shown. When the data is refreshed on the screen, the change done previously on the block will not be seen (this is because the block updateallowed is set to NO), how do we stop the fields of the block being editable?
We don't want to go ahead with this solution as, we might find several similar screens nad its diff to modify each one of them individually. When they work properly in 6i, what it doesn't in 10g? does it require any registry setting?
Regards,
Priya

Unable to launch oracle applications after installing 10g Express

I installed 10g express to be able to access the database using a client (TOAD). Now I am unable to launch the oracle applications. I am able to login but once I select a responsibilty and function java never launches. Any suggestions?

Hi,
could you please let us know more about where you installed express database and why your applicatin is not working?
But lets say if you have installed express database on your laptop and on your application is not launching, then problem could be with your application and browser. There is no connection between client and oracle application client.

Option -splash and -Xmx result in "Unable to launch JVM" error

Hello everybody,
we have a severe problem with launching our Java application using the "-splash:" and "-Xmx" command line options for which we cannot find any solution in the web. Our application needs a lot of heap space, so we usually set "-Xmx=920M". Usually, we are working with Java 6 and use the "-splash:" option to show a splash screen while the application is loading. In some cases, we get an "Unable to launch JVM" error now. This happens only on particular customer systems (servers as well as desktop machines) and the only solution is to decrease the maximum heap size for a couple hundred megabytes. The latter is usually unacceptable since our application requires a lot of heap memory and the machines do have more than sufficient memory. The other option is to completely remove the "-splash:" option, but then there is of course no splash screen anymore.
Unfortunately, we are unable to track the error back and to figure what exactly is going wrong. Does anyone of you have any hints how to debug or analyze the error? Our assumption is that something is wrong due to memory partitioning which leads to unsufficiently large memory partitions to allocate the required heap memory by the JVM.
Any ideas?
Thank you very much.

It is already hard for you to diagnose such an occurrence, I wouldn't expect anything more by asking in a forum. At least you have SOME way of doing some more diagnosing.
I'm sorry, but you'll have to dive in deep. Figure out what update versions of Java the failing machines are running. Which OS. Which processor architecture. Etc. See if there is a common factor involved. If not, hunt through release notes of newer JDKs to see if any of them mention something related to the splash screen and if you find something, let the client attempt an update of the JDK on such a failing machine to see if the problem is remedied. If it is windows, try running with the server VM (java -server) in stead of the default client VM, if you are not already doing that.
And yeah if all that fails and nobody else has something to add, I'm sorry to say that Oracle support will be your next logical step.

Getting error while creating form and report on webservice: ORA-20001: Unable to create form on table. ORA-02263: need to specify the datatype for this column.

i am using the following description to create a web service reference:

Then i tried to create form and report on webservice:
Web Service Reference Type: Yahoo Map

All the fields i keep as default
I tick the checkbox (url)in report Parameter
After clicking next whereever required i click create button
I get the following error
ORA-20001: Unable to create form on table. ORA-02263: need to specify the datatype for this column.
Please someone help to solve this as i need to fix it urgently.

i exported the application from apex.oracle.com and imported it to our environment
import went fine, but when I ran the IR page I got
ORA-20001: get_dbms_sql_cursor error ORA-00904: : invalid identifier
evidently the problem is a lack of public execute on DBMS_LOB, which is used in the generated IR source.
while waiting for the DBA to grant privs on DBMS_LOB, changing the dbms_lob.getlength call to length() fixes the IR.
however, i am not getting the download link on the associated form page... changed templates, that's not the issue -- we'll see if that's a dbms_lob issue as well

Hi --
You can find the HTTP port allocated to the Oracle HTTP Server by using the opmnctl utility.
Try this:
$ORACLE_HOME/opmn/bin/opmnctl status -l
This should spit out a table showing all the managed processes and also the ports they are currently asssigned.
Look for the HTTP_Server entry and the corresponding HTTP port it is using, then use that as the server:port entry to access EM.
Typically on Windows we default to port 80 and on the *nixes we default to 7777. If those ports are not available at install time then the installer will increment the value sequentially until if finds a free port.
