#                       hot_database_backup.sh
# ---------------------------------------------------------------------------
#  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.

# If this script is executed from a NetBackup schedule, NetBackup
# sets an NB_ORA environment variable based on the schedule type.
# The NB_ORA variable is then used to dynamically set BACKUP_TYPE
# For example, when:
#     schedule type is                BACKUP_TYPE is
#     ----------------                --------------
# Automatic Full                     INCREMENTAL LEVEL=0
# Automatic Differential Incremental INCREMENTAL LEVEL=1
# Automatic Cumulative Incremental   INCREMENTAL LEVEL=1 CUMULATIVE
#
# For user initiated backups, BACKUP_TYPE defaults to incremental
# 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 /@' 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.
