# Below are two sets of SQL statements, each of which creates a new
# control file and uses it to open the database. The first set opens
# the database with the NORESETLOGS option and should be used only if
# the current versions of all online logs are available. The second
# set opens the database with the RESETLOGS option and should be used
# if online logs are unavailable.
# The appropriate set of statements can be copied from the trace into
# a script file, edited as necessary, and executed when there is a
# need to re-create the control file.
#
#     Set #1. NORESETLOGS case
#
# The following commands will create a new control file and use it
# to open the database.
# Data used by the recovery manager will be lost. Additional logs may
# be required for media recovery of offline data files. Use this
# only if the current version of all online logs are available.
