Oracle database 12cRAC异地恢复至单机

环境

rac 环境 byoradbrac Oracle12.1.0.2

系统版本：Red Hat Enterprise Linux Server release 6.5
软件版本：Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit
byoradb1：172.17.38.44
byoradb2：172.17.38.45

单机环境 byoradb Oracle12.1.0.2

系统版本：CentOS Linux release 7.9.2009
软件版本：Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit
byoradb：172.17.38.55

rac环境挂载共享盘

可参考Linux 挂载 linux/Windows 共享目录

在服务器端（172.17.38.55）安装 NFS

sudo yum install nfs-utils

创建要共享的目录

创建一个名为 /shared 的目录：

sudo mkdir /shared

修改 NFS 配置文件

编辑 /etc/exports 文件，添加你想要共享的目录和允许访问的客户端 IP 地址。例如：

sudo vi /etc/exports

在文件中添加以下行（替换为你的客户端 IP 地址）：

/shared 172.17.38.44(rw,sync,anonuid=502,anongid=501)

anonuid 为 172.17.38.44 上oracle用户id
anongid 为 172.17.38.44 上 oinstall 组id

 exportfs -r

配置即时生效
启动 NFS 服务

sudo systemctl start nfs-server
sudo systemctl enable nfs-server

在客户端（172.17.38.44）挂载共享目录

创建一个挂载点/nob：

sudo mkdir /nob

可以使用以下命令将服务器的共享目录挂载到这个挂载点：

sudo mount -t nfs 172.17.38.55:/shared /nob

rac备份

备份脚本

rman target /
run {allocate channel ch1 device type disk format '/nob/backup/datafile_backup_%U';backup database include current controlfile spfile;release channel ch1;allocate channel ch2 device type disk format '/nob/backup/controlfile_backup_%U';backup current controlfile;release channel ch2;allocate channel ch3 device type disk format '/nob/backup/spfile_backup_%U';backup spfile;release channel ch3;
}

创建参数文件(基于单机或rac创建都可以)

SQL> create pfile='/shared/backup/initbyoradb.ora' from spfile;

修改参数文件

此处使用单机pfile修改需先在单机安装数据库
也可使用rac环境pfile修改需注意各个文件路径

vi /shared/backup/initbyoradb.orabyoradb.__data_transfer_cache_size=0
byoradb.__db_cache_size=1761607680
byoradb.__java_pool_size=16777216

*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=2310m
*.undo_tablespace='UNDOTBS1'

需注意是否使用pdb，如果使用pdb，此参数应为true

 enable_pluggable_database=true

单机恢复（172.17.38.55）

需预先安装好数据库软件
可参考
Oracle database 静默安装 oracle12c 一键安装 12.1.0.2

复制备份文件并修改权限

mkdir /backup
cd /shared/backup
cp * /backup
chown oracle:oinstall -R /backup

恢复控制文件

rman target /#开启数据库至nomount状态 注意参数文件位置与权限
startup nomount pfile 'backup/initbyoradb.ora';
#恢复控制文件
restore controlfile from '/backup/controlfile_backup_k12fejsm_1_1';
#开启数据库至mount
alter database mount;
#注册备份文件
catalog start with '/backup/'

修改redo路径

RMAN> select * from v$logfile;alter database rename file '+DATA/byoradb/redo01.log' to  '/oracledata/app/oracle/oradata/onlinelog/redo01.log';
alter database rename file '+DATA/byoradb/redo02.log' to  '/oracledata/app/oracle/oradata/onlinelog/redo02.log';
alter database rename file '+DATA/byoradb/redo03.log' to  '/oracledata/app/oracle/oradata/onlinelog/redo03.log';
alter database rename file '+DATA/byoradb/redo04.log' to  '/oracledata/app/oracle/oradata/onlinelog/redo04.log';

修改数据文件路径（rac上查询）

select  file# ,name  from v$datafile;

在这里插入图片描述

#根据实际情况修改sql
select 'SET NEWNAME FOR DATAFILE '|| file# ||' to ' ||'''/oracledata/app/oracle/oradata/DATAFILE'|| substr(name,INSTR(name, '/',-1))  ||''''|| ';' from v$datafile;

在这里插入图片描述
修改成单机数据文件期望存放位置
注意目录需提前创建好、

执行恢复脚本

打开数据库

>RMAN alter database open resetlogs；

顺利的话直接打开、不顺利的话根据报错排查trc

#xxxx 为报错的进程id
find / -name  *xxxx*.trc

如果极端情况问题无法解决
可参考此文章中的重建控制文件方式、
Oracle Database 11g RAC 迁移至单机

可能遇到的问题

如果 trc文件中提示asm background 之类的信息
是12.1的bug、需要打补丁解决
