Hello and Welcome to LinuxQuestions,
You should first try searching Google. Next if you don't find what you're looking for you should provide as much detail as possible concerning your question/problem. And last but not least: Don't ask LQ users to provide howto guides, those can be found in high numbers using Google. That being said, since you provide very little information I can only assume you're referring to the Forms services in Oracle. Have a look at this site: Oracle Documentation
. If this is not what you're looking for, then please specify in more detail what it is you are searching for. Have fun with Linux.
