RMAN_NETBACKUP_ISSUE

[haridba]

HI All,

  Iam using RMAN NET BACKUP , from sample script taken from /usr/openv/netbackup/ext/db_ext/oracle/samples/rman

this location , while runnning the script out put contains only few lines no information about backup . please tell me what is the mistake i did in that script.

Thankfull if you help me solve this. thanks,

#  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.

# Automatic Full                     INCREMENTAL LEVEL=0
# Automatic Differential Incremental INCREMENTAL LEVEL=1

# 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

#
# 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 NET SERVICE NAME: When connecting to a database
#  using a net service name, 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.

It looks like RMAN drops output but only shows prompt. For workaround, remove strings "msglog $RMAN_LOG_FILE append" from this script.

if no luck, check if RMAN or Oracle of your version have any defect with which RMAN drops output. Also try to run thus RMAN command and check if you can get any output in RMAN.

RUN {ALLOCATE CHANNEL t1 TYPE sbt; RELEASE CHANNEL t1;}

  TARGET_CONNECT_STR=/

should be in this format

  TARGET_CONNECT_STR=username/password

using correct username and password for your dvhst11i instance
