Goal

Questions regarding 'thread safety' and 'cache sharing' as they are related to the use of Wrapper UBEs.

  1. Does a Child UBE share the same Thread as its Parent UBE?
    For Example: R55XXXA uses B55XXXA and calls R55XXXB.  R55XXXB also uses B55XXXA.  Is there any chance that R55XXXA and R55XXXB will share the same cache?

  2. Is a Child UBE Threadsafe from a Parent UBE?
    Oracle Documentation states that UBEs are Threadsafe. What isn't clear is whether they are threadsafe between Calling and Called? Are the children of a wrapper UBE considered Threadsafe from each other?
