Forms 11gr2 integrating with oam 11gr2 throgh webgate

I'm trying to configure oracle forms and reports 11.1.2.2 integrating with OAM 11.1.2.2. Linux 6.5 weblogic 10.3.6. The recommended way is through webgate.

I installed and configured OID 11.1.1.7, OIM/OAM 11.1.2.2, webgate 11.1.2.2, webtier 11.1.1.7. OID sync with OIM well. Then I installed and configured forms and reports with option of choosing to use the Application Identity Stores. I followed DOC ID 1441904.1

My questions are:

I have two ohs, one is created when forms configured, another is webtier. What do I need to do to be able to launch my forms through webtier?

Thanks
