Oracle 11g RMAN 备份异机恢复并创建新DBID
实验环境：
Oracle Version：11gR2 System：IBM AIX 5L
Target Database:orcl Auxiliary Database:orcl
NOTE：
（1）RMAN 异机恢复的时候，db_name必须相同。如果说要想改成其他的实例名，可以在恢复成功后，用nid 命令修改。实例名的信息会记录到控制文件里，所以如果在恢复的时候，如果实例名不一致，恢复的时候会报错。
（2）如果恢复的路径和源库不一致，就需要在restore时用set 命令指定新位置。并且使用switch datafile all将信息更新到控制文件中。
在做duplicate的时候，RMAN 会自动根据pfile中的log_file_name_convert和db_file_name_convert来进行set 的转换。手工restore时，只能使用set 命令转换。
（3）异机恢复对相同目录和不同目录都做了说明。
（4）最后测试了NID 修改DBID 和DBNAME.
实验步骤：
一. Target库准备工作：
1. 查询DBID

2. 备份Target Database

传递备份集完成
二.Auxiliary库准备工作：
1. 创建口令文件
$ cd $ORACLE_HOME/bin
$ orapwd file=$ORACLE_HOME/dbs/orapworcl password=oracle entries=8
$ cd $ORACLE_HOME/dbs
$ ls
init.ora initorcl.ora orapworcl
2. 构建辅助数据库目录结构
2.1 Oracle data 目录
$ mkdir -p /u01/oradata/orcl
2.2 其他目录
$ mkdir -p /u01/app/oracle/admin/orcl/adump
$ mkdir -p /u01/app/oracle/admin/orcl/dpdump
$ mkdir -p /u01/app/oracle/admin/orcl/pfile
$ mkdir -p /u01/app/oracle/admin/orcl/scripts
$ mkdir -p /u01/app/oracle/diag
$ mkdir -p /u01/app/oracle/flash_recovery_area/orcl
3. 创建初始化参数
将Target库的pfile文件copy过来。
也可以使用RMAN从我们Target库的备份集中恢复，因为我们之前备份过spfile。不过使用RMAN，DB要先启动到nomout状态。这个可以用默认的init.ora来启动。
SQL> startup nomount pfile=?/dbs/initorcl.ora

如果修改数据文件保存的位置，那么要修改控制文件的相关的参数：
*.control_files='/u01/oradata/control01.ctl','/u01/oradata/control02.ctl','/u01/oradata/control03.ctl'
*.db_name='mahee'
4. 将用pfile将Auxiliary库启动到nomout状态

restore的时候需要控制文件，控制文件恢复的位置，是我们在pfile中的control_files参数控制的。
6. 将Auxiliary DB启动到mout状态
RMAN> sql 'alter database mount';
sql statement: alter database mount
released channel: ORA_DISK_1
7. restore数据库
7.1 恢复目录不同的情况：
因为我们的路径不同，所以我们需要使用set命令转换一下路径。
到Target库查询一下：
SQL> select file_id,file_name from dba_data_files order by 1;
FILE_ID FILE_NAME
---------- --------------------------------------------------
1 /u01/app/oracle/oradata/orcl/system01.dbf
2 /u01/app/oracle/oradata/orcl/sysaux01.dbf
3 /u01/app/oracle/oradata/orcl/undotbs01.dbf
4 /u01/app/oracle/oradata/orcl/users01.dbf
5 /u01/app/oracle/oradata/orcl/example01.dbf
NOTE: restore的时候不会对temp表空间进行restore。所以restore之后，我们需要手工创建temp表空间。
RMAN> RUN {
2> set newname for datafile 1 to '/u01/oradata/orcl/system01.dbf';
3> set newname for datafile 2 to '/u01/oradata/orcl/sysaux01.dbf';
4> set newname for datafile 3 to '/u01/oradata/orcl/undotbs01.dbf';
5> set newname for datafile 4 to '/u01/oradata/orcl/users01.dbf';
6> set newname for datafile 5 to '/u01/oradata/orcl/example01.dbf';
7> restore database;
8> switch datafile all;
9> }
对switch datafile all的说明：
--对于nocatalog模式下，rman备份的信息是保存在控制文件里的，包括文件的路径信息。 这里的switch datafile all的作用，就是更新控制文件里的信息。

之后会报一个错误：
RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 16 and starting SCN of 1109237
这里是提醒恢复到一个未知的scn号。在alter database mount之后，通过set until scn或者set until time命令设置恢复到的scn号或时间，就可以避免这个错误。
9. 用open resetlogs打开数据库
SQL> alter database open resetlogs;
Database altered.
我测试的平台是11gR2的版本，在open resetlogs之后，自动在原来默认的路径创建了temp表空间和3组redo文件。
如果恢复目录和原来相同，就不用修改。
如果目录不同，我们就需要把这些文件移到我们现在的data目录。
源目录：
$ cd /u01/app/oracle/oradata/orcl
$ ls
redo01.log redo02.log redo03.log temp01.dbf
现在的目录：
$ cd /u01/oradata/orcl
$ ls
control01.ctl example01.dbf sysaux01.dbf system01.dbf undotbs01.dbf users01.dbf
（1）处理online redo log
SQL> select group#,bytes/1024/1024||'M',status from v$log;
GROUP# BYTES/1024/1024||'M' STATUS
---------- ----------------------------------------- ----------------
1 50M CURRENT
2 50M UNUSED
3 50M UNUSED
SQL> select group#,member from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------
3 /u01/app/oracle/oradata/orcl/redo03.log
2 /u01/app/oracle/oradata/orcl/redo02.log
1 /u01/app/oracle/oradata/orcl/redo01.log
oracle至少有2组redo log。所以我们可以将已经完成归档的redo drop掉，重新创建。
SQL> alter database drop logfile group 3;
SQL> alter database add logfile group 3 ('/u01/oradata/orcl/redo03.log') size 50m;
Database altered.
SQL> alter database drop logfile group 2;
Database altered.
SQL> alter database add logfile group 2 ('/u01/oradata/orcl/redo02.log') size 50m;

3 /u01/oradata/orcl/redo03.log
2 /u01/oradata/orcl/redo02.log
1 /u01/oradata/orcl/redo01.log
（2）处理temp临时表空间
SQL> select name from v$tempfile;
NAME
--------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf
--表空间offline
SQL> alter database tempfile '/u01/app/oracle/oradata/orcl/temp01.dbf' offline;
Database altered.
--在OS级别移动temp的数据文件
SQL> !mv /u01/app/oracle/oradata/orcl/temp01.dbf /u01/oradata/orcl/temp01.dbf;
--修改控制文件中temp文件的信息
SQL> alter database rename file '/u01/app/oracle/oradata/orcl/temp01.dbf' to '/u01/oradata/orcl/temp01.dbf';
Database altered.
--temp表空间online
SQL> alter database tempfile '/u01/oradata/orcl/temp01.dbf' online;
Database altered.
--验证
SQL> select name from v$tempfile;
NAME
--------------------------------------------------
/u01/oradata/orcl/temp01.dbf
10. NID修改DBID和DBNAME
先查看，这个和我们之前的一样
SQL> select name,dbid from v$database;
NAME DBID
-------------------------------------------------- ----------
ORCL 1275959622
NOTE：
（1）在修改DBID期间仍然可能会遇到不可恢复的错误，所以修改之前备份数据库，特别是控制文件，因为nid会修改控制文件中的信息。
（2）需要将DB启动到mount状态才能修改。
SQL> shutdown immediate
SQL> startup mount;
在执行NID命令之前：一定要关闭所有的session连接。
nid命令到执行的最后会关闭数据库，如果有session连接，就会阻止这个操作，修改dbid就会被挂死。如果中断这个操作，修改就会失败，数据库就不能mount，需要恢复。
（1）只改DBID，不改db_name
$ nid target=sys/oracle

（2）修改DBID和DB_NAME
注意一点，修改DB_NAME之前，要将spfile创建成pfile，因为修改dbname之后，原来的参数文件就没用了。所以要保证最新的参数。 还需要修改DB_NAME的值为最新值。修改完之后，然后用这个新参数启动DB.
SQL> create spfile from pfile='?/dbs/initorcl.ora';
File created.
SQL> create pfile='/u01/inittmp.ora' from spfile;
File created.
