I am working on Oracle Financials 11.0.3 on Oracle server 8.0.5 on OWS 3.0.1.

In general it takes 3 days or more to install and configuer the whole software , it is very exhausting operation , you need to install every every thing manually starting from creating software directories.

You must have got a CD containing documentation , this CD conatins a whole manual for installing and onfiguering all the parts of the sotware.

You must be very aware when dealing with this environment , you must start the application every time by a certain steps like : start DB , listeners , Concurrent managers ....
and when closing it reverse the issue .

Be sure to stick with it or you will get many problems.

You can not just copy objects , you need to install a new one to have a separated environment.

It is totally recommended no to start the request brokers manually , let them get up with the NT when starting up and never shutdown them manual or start them manual.

There are two type of Installation for Oracle Applications , the Auto Install ( the manual way ) or the One hour Install ( the automatic way ) ,, I am suggesting to Install using the one hour install untill reading the Installation maunal of The Auto install version ( more than 400 pages ).

I am recommending also to get an experienced persion in installing Oracle applications at least at the first time , the issue is complicated an not easy to hadle so call Oracle Support whenever needed.

Hope I was Useful.
