# title:        Creator user name is empty in user trace sessions
# decription:
#                   We create trivial config for trace, start session and stop it.
#                   Trace list must contain string: '  user: SYSDBA ' (without apostrophes).
#                   We search this by string using pattern matching: such line MUST contain at least two words
#                   (it was just 'user:' before this bug was fixed).
#                   Confirmed bug on: 3.0.2.32658, 3.0.4.33054, 3.0.5.33097
#                   Checked on:
#                        4.0.0.1421: OK, 5.186s.
