Your database is running in NOARCHIVELOG mode with two online redo log files. The SALES table contains sales information for the organization. The SALES table belongs to the SALESTB tablespace. On Monday， you insert 10 rows into the SALES table. The current log sequence number is 14. You change the tablespace status from READ WRITE to READ ONLY for the SALESTB tablespace. You shut down the database and take a backup of the SALESTB tablespace. On Tuesday， you start the database. You change the status for the SALESTB tablespace from READ ONLY to READ WRITE.
