10g vs 11g differences?

Question

I'm planning an upgrade of Forms 10g to 11g. We have a customized basejpi.htm file and I was comparing it to the 11g basejpi.htm file for differences and noticed that besides a few additional parameters (%parameter%) in 11g there were some that were not in the 11g basejpi.htm file that were in the 10g file especially ones referring to the SSO. Are these parameters no longer needed? Is there any documentation on what variables are needed and what are optional?

Answer 1

Let me start by saying what I say often to our customers that are upgrading from old versions to new versions.... Every new version should be viewed as a new product with some backward compatibility support. For some reason customers seem to think each new release is the same as the old. It wouldn't be new if it was the old ;) So this leads to my point. Do not attempt to take configuration files from old versions and use them with new versions. Changes should be made directly to the new files in order to prevent the possibility of overlooking changes in the new one. For example new parameters or obsoleted parameters and or values. Other critical changes may include things like adherance to formating. By taking an old file an dropping it in a new version's environment may cause unpredictable behavior depending on exactly which config file is moved. More importantly, doing this is not at all supported.
Also important to note is that in version 11, administrators are discouraged from making changes to configuration files manually. All changes should be made from within EM unless a particular configuration file is not managed by EM. Manual changes to config files resulting in errors/failures will not be supported by Oracle. In other words, if a problem only occurs when you alter a config file manually, but does not occur if/when you attempt the same from within EM, the issue will not be deemed a defect.
As for your specific question related to SSO I can offer the following. As mentioned above, v11 is a very different animal compared to 10. Although the basic components like Forms have remained mostly the same (at least on the surface), changes/improvements have been made which resulted in some obvious and not so obvious differences such as the one you noted. In v11 for example, there is no included SSO solution as there was in v10 where we included all of the necessary OID/SSO components and configurations. In 11 you must now add SSO/OID as a separate installation. Therefore configuration of SSO in Forms occurs after you complete the setup for SSO integration. And yes, some internal changes have also been made, so the exact parameters used in v10 may not be the same in v11.
For details about using SSO in v11, refer to the product documentation:
