Netbackup恢复步骤-01

前段时间，做了一次nbu的同机恢复测试。
环境是这样的：
备份和还原都是在一个机器上，hostname是sg2as059。即备份的client是这个机器。数据库的实例名是test.
无catalog数据库，备份信息保留在控制文件中。
备份的master server和media server是同一台机器，hostname是sg2ts001。

前一天晚上设置nbu的policy进行备份，备份脚本在client上：

oracle@sg2as059:/usr/openv/netbackup/ext/db_ext/oracle/test> pwd
/usr/openv/netbackup/ext/db_ext/oracle/test
oracle@sg2as059:/usr/openv/netbackup/ext/db_ext/oracle/test> cat hot_database_backup.sh
#!/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 [ -f "$RMAN_LOG_FILE" ]
then
        rm -f "$RMAN_LOG_FILE"
fi
 
# -----------------------------------------------------------------
# Initialize the log file.

echo >> $RMAN_LOG_FILE
chmod 666 $RMAN_LOG_FILE

# Log the start of this script.
