# 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.
# Determine the user which is executing this script.

# NOTE: This script assumes that the database is properly opened. If desired,
# this would be the place to verify that.
# 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 <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.
