Veritas NetBackup Oracle客户端配置步骤
Veritas NetBackup Oracle客户端配置步骤
至此NBU Oracle Agent安装完毕，执行下述步骤：

1、正常的关闭oracle数据库

# su - oracle

$ sqlplus ‘/as sysdba’

sqlplusshutdown immediately

sqlplusexit

2、以oracle用户的身份，执行oracle_link

$ /usr/openv/netbackup/bin/oracle_link

3、在数据库服务器的数据分区内创建数据库备份脚本目录

# mkdir /oracle/ora_bak_scripts

4、创建oracle备份的脚本

# cp –r /usr/openv/netbackup/ext/db_ext/oracle/samples/rman/* /data01/bak_scripts

5、根据实际情况编辑oracle备份脚本

在我们拷贝到数据库备份脚本目录中的范本文件中，我们比较多使用的是hot_database_backup.sh （联机数据库备份脚本）。以下说明如何编辑数据库备份脚本。

#!/bin/sh
# $Header: hot_database_backup.sh,v 1.2 2002/08/06 23:51:42 $

# 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.
# ---------------------------------------------------------------------------

CUSER=`id |cut -d;(; -f2 | cut -d ;); -f1`

# ---------------------------------------------------------------------------
# Put output in this file name.out. Change as desired.
# Note: output directory requires write permission.
# ---------------------------------------------------------------------------

RMAN_LOG_FILE=${0}.out

# ---------------------------------------------------------------------------
# You may want to delete the output file so that backup information does
# not accumulate. If not, delete the following lines.
# ---------------------------------------------------------------------------

# 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 isBACKUP_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.
