    #  This script uses Recovery Manager to take a hot (inconsistent) database
    #  backup. A hot backup is inconsistent because portions of the database are
    #  being modified and written to the disk while the backup is progressing.
    #  You must run your database in ARCHIVELOG mode to make hot backups. It is
    #  assumed that this script will be executed by user root. In order for RMAN
    #  to work properly we switch user (su -) to the oracle dba account before
    #  execution. If this script runs under a user account that has Oracle dba
    #  privilege, it will be executed using this user's account.

    # level 0 (full).  To change the default for a user initiated
    # backup to incremental or incremental cumulative, uncomment
    # one of the following two lines.
    # BACKUP_TYPE="INCREMENTAL LEVEL=1"
    # BACKUP_TYPE="INCREMENTAL LEVEL=1 CUMULATIVE"
    #
    # Note that we use incremental level 0 to specify full backups.
    # That is because, although they are identical in content, only
    # the incremental level 0 backup can have incremental backups of
    # level > 0 applied to it.
    # ---------------------------------------------------------------------------

    # ---------------------------------------------------------------------------
    # Call Recovery Manager to initiate the backup. This example does not use a
    # Recovery Catalog. If you choose to use one, replace the option 'nocatalog'
    # from the rman command line below with the
    # 'rcvcat <userid>/<passwd>@<tns alias>' statement.
    #
    # Note: Any environment variables needed at run time by RMAN
    #       must be set and exported within the switch user (su) command.
    # ---------------------------------------------------------------------------
    #  Backs up the whole database.  This backup is part of the incremental
    #  strategy (this means it can have incremental backups of levels > 0
    #  applied to it).
    #
    #  We do not need to explicitly request the control file to be included
    #  in this backup, as it is automatically included each time file 1 of
    #  the system tablespace is backed up (the inference: as it is a whole
    #  database backup, file 1 of the system tablespace will be backed up,
    #  hence the controlfile will also be included automatically).
    #
    #  Typically, a level 0 backup would be done at least once a week.
    #
    #  The scenario assumes:
    #     o you are backing your database up to two tape drives
    #     o you want each backup set to include a maximum of 5 files
    #     o you wish to include offline datafiles, and read-only tablespaces,
    #       in the backup
    #     o you want the backup to continue if any files are inaccessible.
    #     o you are not using a Recovery Catalog
    #     o you are explicitly backing up the control file.  Since you are
    #       specifying nocatalog, the controlfile backup that occurs
    #       automatically as the result of backing up the system file is
    #       not sufficient; it will not contain records for the backup that
    #       is currently in progress.
    #     o you want to archive the current log, back up all the
    #       archive logs using two channels, putting a maximum of 20 logs
    #       in a backup set, and deleting them once the backup is complete.
    #
    #  Note that the format string is constructed to guarantee uniqueness and
    #  to enhance NetBackup for Oracle backup and restore performance.
    #
    #
    #  NOTE WHEN USING TNS ALIAS: When connecting to a database
    #  using a TNS alias, you must use a send command or a parms operand to
    #  specify environment variables.  In other words, when accessing a database
    #  through a listener, the environment variables set at the system level are not
    #  visible when RMAN is running.  For more information on the environment
    #  variables, please refer to the NetBackup for Oracle Admin. Guide.
