— 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.
