REM   NAME
REM       wf260dat.sql - WorkFlow 2.6.0 Data Upgrade Script
REM
REM   DESCRIPTION
REM       Upgrade Workflow 2.5/2.6 -> Workflow 2.6.2 data.
REM
REM   USAGE
REM       sqlplus apps/apps @wf260dat APPS APPS APPLSYS APPS
REM       sqlplus wfinst/wfinst @wf260dat WFINST WFINST WFINST WFINST
REM
REM   NOTES
REM       Rebuild the Deferred Queue to be multi-consumer queue.
REM       Note that the enqueue order is not preserved.
REM       This script rebuilds the deferred queue tagging the schema 
REM       name to the correlation which is required in 2.6
REM
REM   MODIFICATION LOG:
REM       01/2002 JWSMITH BUG 2001012 - Increased l_wf_schema to varchar2(320)
