As per the reading of the documentation PeopleSoft_Statement_Of_Direction_May_2011.pdf (MOS note #1320581.1), we can understand Oracle is providing termplates ready to go for production use :
"+...PeopleTools will continue to provide production-ready templates that allow IT staff to get a PeopleSoft system online quickly or to dynamically add or remove PeopleSoft components from a PeopleSoft application...+"
But from the readme documentation delivered in the templates, it sounds an other story (here's the output of the last OVM template) :
"+...This template was built for demo purposes. Out of the box it is not recommended for production use...+"
Not sure how to understand both sentences and if they match somehow.
