# title:        gfix -online normal <db> (being issued in window #1) does not produce error when there is sysdba attachment in window #2
# decription:
#                   We create new DB and immediately change its state to single-user maintanance.
#                   Then we attach to this DB ans run (in separate process) 'gfix -online normal <localhost:this_db>'.
#                   This command must produce in its STDERR error: "database ... shutdown" - and we check that this actually occurs.
#                   Also, we check that after reconnect to this DB value of mon$database.mon$shutdown_mode remains the same: 2.
#
#                   Confirmed bug on: 4.0.0.1850 SS, 3.0.6.33276 SS - no error when doing 'gfix -online normal'.
#                   Checked on 4.0.0.1881 SS, 3.0.6.33283 SS -- all fine, DB state is not changed to normal.
