register a oracle view to geodatabase

[SantoshV]

HI,
  I have created an oracle view which I will be using to create an layer using MakeRouteEventLayer (Linear Referencing)from ArcToolBox but I see that I am unable to do this as the view is not getting registered with Geodatabase
Is this because I don't have an column with objectid?

if yes then what is the solution, should I create an sde view coz the syntax looks difficult and my oracle query to create the view is a bit complex

please suggest/correct me on this
