    FRM-92102 - A network error has occured

    451826
      Hi,
      I'm deploying a forms 9i application on the intranet. I'm using Oracle Application Server Forms and Reports Services 9.0.4 under Red Hat Linux AS 4.0, along with an Oracle 9i Database on another server (actually multiple databases, used for benchmarking). Every time I connect from a remote PC on the network under Windows XP Pro or Windows 2003 Server, after a few seconds or minutes, I get the error message: FRM-92102 - A network error has occured after ...
      I did a lot of research on the internet. I'm using Internet Explorer 6.0, so I tried from Netscape 8.0 and Netscape 7.0, but I got the same problem. I changed the networkRetries in the formsweb.cfg to 5, but it didn't change anything.
      On the other hand, I installed the Oracle Application Server Forms and Reports 9.0.4 on a Windows platform and it works perfectly, with no network error problems.
      Also note that the Forms 9i application uses Webutil.
      So, right now, I'm a bit lost. Can anyone please tell me if there is some parameter I have to set, or something I should do to make it work?
      Thanks a lot

          And one more thing.
          I'm not using neither a firewall, nor a proxy on the Linux Server or on the client side.

            Did you make sure you followed every item on the long list of pre-requisites?

              Hi orafad,
              if you mean the list of prerequisites for the installation of the Oracle Application Server 10g under Linux, yes I did. I was having some troubles in the beginning, but then it worked fine. I installed all the necessary packages, changed all the kernel parameters, the environment variables, ... The installation was totally successful. I then configured the application server (made changes in default.env, formsweb.cfg, forms90.conf, registry.dat, webutil.cfg, ...), compiled the forms I will need for my application, along with the libraries.
              And now, I'm stuck with this network error.

              Thanks

                What is the full FRM-92102 message?

                Do you get any related errors in the server side logs?

                You may want to try the Forms forum, which may be more suitable when it comes to Forms applications.

                  Hi,
                  this is the full FRM-92103 message:

                  FRM-92102: A network error has occurred.
                  The Forms Client has attempted to reestablish its connection to the Server 5
                  time(s) without success.
                  Please check the network connection and try again later.
                  Details...
                  Java Exception:

                  On the server, no error is recorded
                  It is more an application server error, because it is not related to a particular form, but to any form that is loaded.
                  Thanks

                    how does your .env file looks like or are you using the default.env.

                    In the env file you need to use the absolute path's .

                    Regards,

                      Hi Lia,
                      I'm using the default.env file. All the path I set there are absolute paths.
                      I set the FORMS90_PATH to the libs and the fmx of my application (along with the forms90 path), I set the WEBUTIL_CONFIG variable to the path of th webutil.cfg file and I added to the beginning of the CLASSPATH the path to the files webutil.jar and rt.jar

                      Thanks
                      jy

                        Have you tried Note:330165.1 from metalink.

                        It looks like your problem.

                          Lia,
                          I already checked the note 330165.1
                          Its almost like my case, because in their case, they wait for about 15 to 20 minutes before they get the error. In my case, almost a soon as I login, I get the error (when I can login of course). Anyway, I tried to set the parameter session-timeout to 60 and restarted the application server but it didn't change anything.

                          Thanks

                            Hmm, error code 500 should leave something in the oc4j and/or ohs logs. Also check opmn logs.

                            If no log info, you might want to enable session tracing (se Forms docu).

                            When you get the error, what does url to forms listener (/forms90/l90servlet?) produce?

                            Have you tried increasing retries even more? (for debugging)

                              It's weird
                              I tried to set the network retries to 25, restarted the application server listener, but when the error occurred, it only retried 5 times.

                              I tried to look into the logs but couldn't really see what might be interesting. i checked the opmn logs. As for the oc4j and the ohs logs, where do i look for them?

                              I didnt understand what you meant about the url that should be produced.

                              Thanks

                                  On linux you can use
                                  $ find /u00 -cmin -1
                                  to see what under /u00 has changed within the minute.

                                  When "network error" occurs, try http://srvname:7778/forms90/l90servlet or the corresponding on your site/installation.

                                    First, when the network error occurred, I ran the url on the site server. It gave me the following page:
                                    Oracle Application Server 10g Forms Services

                                    The Forms Listener servlet is up and running

                                    as for the modified files during the last minute, here is what I got:
