Rem NAME
Rem   XAVIEW.SQL
Rem FUNCTION
Rem   Create the view necessary to do XA recovery scan of prepared
Rem   and heuristically completed transactions.
Rem NOTES
Rem   The view 'XATRAN' basically combines information from two
Rem   different types of tables:
Rem      pending_trans$ & pending_sessions$
Rem      x$k2gte2
Rem   The view v$pending_xatrans$ combines and then filters information
Rem   from the table pending_trans$ and pending_sessions$ into format
Rem   that satisfy XA criteria.
Rem   Then the view v$xatrans$ combines information from x$k2gte2 and
Rem   v$pending_xatrans$.
