1.1 Oracle数据库备份

1.1.1 链接Oracle介质管理库

请在数据库节点上操作。

[oracle@db01/usr/openv/netbackup/bin]$ ./oracle_link

Thu Jul  9 14:35:44 CST 2015

All Oracle instances should be shutdown before running this script.

Please log into the Unix system as the Oracle owner for running this script

Do you want to continue? (y/n) [n] y

LIBOBK path: /usr/openv/netbackup/bin

ORACLE_HOME: /oracle/product/11.2.0/db11g

Oracle version: 11.2.0.4.0

Platform type: x86_64

Linking LIBOBK:

ln -s /usr/openv/netbackup/bin/libobk.so64 /oracle/product/11.2.0/db11g/lib/libobk.so

Done

Please check the trace file located in /tmp/make_trace.36923

1.1.2 数据库信息确认

节点1

SQL> archive log list

Database log mode              Archive Mode

Automatic archival             Enabled

Archive destination            +FLASH_DG

Oldest online log sequence     28963

Next log sequence to archive   28966

Current log sequence           28966

有以上信息可知，数据库归档文件放置在ASM共享存储上，故，后续归档文件备份策略仅需要在1个节点上配置。

1.1.3 确定备份策略名称

数据文件备份策略名称

oracle_db01_full

归档文件备份策略名称

oracle_db01_arch

控制文件备份策略名称

控制文件跟随数据文件和归档文件备份，不单独备份。

1.1.4 备份脚本配置

创建脚本目录，并拷贝模板脚本到目录下

[oracle@db01/usr/openv]$ mkdir scripts

[oracle@db01/usr/openv/netbackup/ext/db_ext/oracle/samples/rman]$ cp hot_database_backup.sh /usr/openv/scripts/

[oracle@db01/usr/openv/scripts]$  cp hot_database_backup.sh  arch.sh

数据文件备份脚本：hot_database_backup.sh

归档文件备份脚本：arch.sh

获取oracle环境变量

[oracle@db01/home/oracle]$ env |grep -i sid

ORACLE_SID= test1

[oracle@db01/home/oracle]$ env |grep -i oracle_home

ORACLE_HOME=/oracle/product/11.2.0/db11g

[oracle@db01/home/oracle]$

1.1.5 修改hot_database_backup.sh脚本

修改如下位置：

ORACLE_HOME=

ORACLE_SID=

ORACLE_USER=

SEND CHANNEL ch00 'NB_ORA_POLICY=

SEND CHANNEL ch01 'NB_ORA_POLICY=

# 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.

# 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

#  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.

1. 进入rman
2. connect target /
3. crosscheck archivelog all;
4. delete expired archivelog all;
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
这2条命令做什么事情，原理是什么。下面说明一下：
在controlfile中记录着每一个archivelog的相关信息，当我们在OS下把这些物理文件delete掉或异常变动后，在controlfile中仍然记录着这些archivelog的信息，当我们手工清除archive目录下的文件后，这些记录并没有被我们从controlfile中清除掉，也就是oracle并不知道这些文件已经不存在了!这时候我们要做手工的清除。

crosscheck archivelog all；的作用就是检查控制文件和实际物理文件的差别。

delete expired archivelog all;就是同步控制文件的信息和实际物理文件的信息。

如果单独执行crosscheck而没有执行delete那么备份还是失败的，原因是那些控制文件的信息和实际的信息还是不同。

crosscheck backupset
crosscheck backupset 是检查备份集和实际的文件

1 备份集有两种状态A(Available,RMAN认为该项存在于备份介质上)X(Expired，备份存在于控制文件或恢复目录中，但
是并没有物理存在于备份介质上）
2 crosscheck 的目的是检查RMAN 的目录以及物理文件，如果物理文件不存在于介质上，将标记为Expired。如果物理文件
存在，将维持Available。如果原先标记为Expired的备份集再次存在于备份介质上（如恢复了损坏的磁盘驱动器后），
crosscheck将把状态重新从Expired标记回Available。
3 crosscheck 输出分两部分。第一部分列出确定存在于备份介质上的所有备份集片，第二部分列出不存在于备份介质上的
备份集片，并将其标记为Expired。当设置备份保存策略后，一个备份过期，crosscheck之后标记为丢弃的备份状态依旧为
availabel,要删除丢弃备份delete obsolete

实例
Unix下 oracle数据库在迁移当中一个归档文件丢失了，rman备份归档日志时提示 某个归档日志找不到，
请问如何在不停止oracle数据库情况下 截断归档日志，重新开始新的归档!

crosscheck archivelog all
delete archivelog all;
