Create pfile from PFCL1(PFCL1  is db name,PFCL11 and PFCL12 are two nodes instance name)

Sqlplus:create pfile=’/u01/home/oracle/deff/pfile_1223.txt’ from spfile;

Then we can shutdown database:srvctl status database -d PFCL1

Srvctl stop database -d PFCL1

When PFCL1 db is shutdown,we can begin restore/recover :

cd /u01/home/oracle/deff

vi pfile_1223.txt

modify these parameter to:

*.cluster_database=false

*.db_name=‘PNCL‘

#*.db_recovery_file_dest=‘+LOGS‘ 注掉这两个参数

#*.db_recovery_file_dest_size=241591910400

Start only PFCL11 nomount: startup nomount pfile=’/u01/home/oracle/deff/pfile_1223.txt’

在开始下面做之前，可以在asm里面把PFCL1相关的数据文件，临时文件全清了

}

Note:

  1. there is no need to set newname for
    tempfile,because tempfile is no needed when doing backup/restore operation
  2. set newname for datafile command can be
    generated from following sql,(run it at PNCL side)

SELECT ‘SET NEWNAME FOR DATAFILE
‘||FILE#||‘ TO ‘‘‘||‘+DATA/PFCL1/DATAFILE‘||

SUBSTR(NAME,

INSTR(NAME, ‘/‘, -1, 1),

INSTR(NAME, ‘.‘,1,2) - INSTR(NAME,
‘/‘,-1,1)) ||‘.dbf‘‘;‘

FROM V$DATAFILE;

3. when use rman to do restore,if we also use set name to modify datafile path,then when restored,the datafile path info in controlfile are not modified,so we need sync control file info ,so we need use   switch datafile all

使用rman进行恢复时，如果使用了set name修改文件路径，那么恢复后，控制文件里面的信息是没有修改该的，如果要同步控制文件的信息那么就需要使用

switch datafile all

all这个可以写文件号的，all表示所有使用set name的都一起保存

4. db_file_name_convert这个参数适用在主备库上时候，在异机恢复时候不起作用（自己也还没试过起不起作用，具体的还是得去官方doc查看下）  参考：http://www.linuxidc.com/Linux/2013-08/88500.htm

control_file这个参数确保是restore之后的control file的位置

*.cluster_database=false

*.db_name=‘PNCL‘

*.db_recovery_file_dest=‘+LOGS‘ 不在注掉这两个参数

*.db_recovery_file_dest_size=241591910400

然后就可以startup pfile=’’

把数据库打开之后，之后就是得把PNCL改成PFCL1这个数据库名，用nid来改

nid要求数据库在mount状态

在做完nid之后，无非就是再修改下pfile，起两个节点，建spfile，中间遇到的小问题就暂时略过了，直接来说下遇到的一个spfile与srvctl的问题：

目标就是spfile放到ASM上+data里的一个目录下，然后能用srvctl顺利启起来，因为自己每次都是改init file指向新的ASM下的SPFILE，每次用srvctl重启就不行，后来看了文章搞清楚了srvctl下的config还没改！

参考这篇文章，写得很清楚~~

在RAC环境下修改spfile：

1. 需要修改$ORACLE_HOME/dbs下的相关文件init file，指向新文件spfile

2. 需要用srvctl修改config信息，指向新文件spfile

参考这篇文章看下自己现在的环境：

oracle异机恢复测试

(一)问题背景 最近在生产环境中,开发人员误操作,使用truncate将oracle数据库某个表的数据全部删除了,在删除之后,开发人员发现自己闯祸了,于是联系值班的DBA进行紧急数据恢复. 经过分析,表被truncate后,使用一般的闪回表.闪回查询.闪回事物等方法,是不可能将数据找回来的,可以使用闪回数据库.闪回数据归档的方法来进行恢复,但是通常在生产环境中,都不会开启这2个特性,所以剩下的只有使用RMAN进行数据恢复了. 对于使用RMAN进行数据恢复,可以在生产环境上直接进行,也可以恢复到其

RMAN异机恢复注意事项: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将信息更新的到控制文件.在做duplicate的时候,RMAN 会自动根据pfile中的log_file_name_convert
