-- 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 Recovery Manager will be lost.

-- Additional logs may be required for media recovery of offline

-- Use this only if the current versions of all online logs are

-- After mounting the created controlfile, the following SQL

-- statement will place the database in the appropriate

-- protection mode:

--  ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE PERFORMANCE
