*********************************************************************
WARNING: The following temporary tablespaces contain no files.
This condition can occur when a backup controlfile has
been restored. It may be necessary to add files to these
tablespaces. That can be done using the SQL statement:
ALTER TABLESPACE <tablespace_name> ADD TEMPFILE
Alternatively, if these temporary tablespaces are no longer
needed, then they can be dropped.
Empty temporary tablespace: TEMP
**********************************************************
WARNING: Files may exists in db_recovery_file_dest
that are not known to the database. Use the RMAN command
CATALOG RECOVERY AREA to re-catalog any such files.
If files cannot be cataloged, then manually delete them
using OS command.
One of the following events caused this:
1. A backup controlfile was restored.
2. A standby controlfile was restored.
3. The controlfile was re-created.
4. db_recovery_file_dest had previously been enabled and
then disabled.
