Pre-requisites for running oracle forms 11G

Question

What are the pre-requisits for running Oracle forms 11G?

Answer 1

Ok - where to begin?
From the beginning....
<blockquote>1. There are prerequisites for nearly every Oracle product. If you have not read the Installation Guide and Systems Requirements Guide you likely are missing something. Docs are [URL http://docs.oracle.com/cd/E24269_01/index.htm]here
2. If you followed the installation guide and completed the installation without error, the basic product works out of the box without any configuration changes. Don't start tweaking unless you understand the change.
3. In order to use an application server of any kind, you need to ensure it is running.
4. If you have chosen the "Development" installation type (applies to 11.1.2 only) then you will not have an HTTP Server and it is not needed. Your listener will be the WLS managed server (usually port 9001).
5. If you have chosed the "Deployment" installation type then you will have HTTP Server. You can access your Forms application via the HTTP Server Listen port (usually 8888) or the WLS_FORMS port.</blockquote>
To the issue that started this post... "+*Page cannot be displayed*+"
This error is either caused as a result of there being no listener running, specifically the HTTP Server or the wrong URL was entered in the browser, or the hostname used in the URL does not map to the correct machine where the listener is running. If you have installed and are testing on your local machine and that machine does not have a static IP address and/or a DNS registered name then fixing these issues would be a few of those "prerequisite" steps I mentioned. This is documented here:
http://docs.oracle.com/html/E18558_01/fusion_requirements.htm#BABFHBID
The above configuration needs to be completed before the installation is started.
To the next issue or change in error message: "+*Failure of server APACHE bridge: No backend server available for connection...*+"
This means that HTTP Server (specifically mod_wls) is unable to contact WLS_FORMS. This could be because WLS_FORMS is not running or because of those prereq steps noted above or a variety of other things related to not following the instructions. Refer to MyOracleSupport Note 1304095.1 for more details about this error.
Finally, as for the need for a JRE, you can do this either before you attempt to run a form or allow the autoinstall feature of the browser perform the installation. However, as Craig mentioned, you would be better off installing the latest version which is 1.6.0_33. You can change your configuration to automatically do this, but if you are new to FusionMiddleware and/or Forms doing the JRE installation manually at this point is probably a good idea. I also recommend starting with Internet Explorer because likely some config changes will be necessary to get it working.
As I mentioned, for the most part, the installation should work out of the box without changes. I would recommend getting the default form (test.fmx) running before attempting to make too many changes.
