直播通过rman将oracle 12c整库全备后进行异机同目录恢复遇到的小坑
来源：互联网 发布：js放大镜效果代码 编辑：程序博客网 时间：2024/05/30 02:24
参考自：http://blog.itpub.net/26506993/viewspace-1873417/
挖坑流程：
1、源库rman全备（备份的过程请自行查阅我另一篇blog）
2、在目标库（要在哪台服务器恢复？）安装好同版本的oracle数据库软件，我这里是12.2.0.1.0，不用建库！不用建库！不同建库！真的不用。。。
3、在目标库创建好与源库一样的目录结构，如果不清楚，可以在源库创建pfile查看。（否则，嘿嘿，有你烦的~）
4、将备份好的备份集（就是备份得到的一坨~~~）传送到目标端（不要告诉我你没用过scp哈！）
5、在目标库export ORACLE_SID=SID（如果你的oracle用户环境变量中设置了，请飘过~）
6、在目标库执行rman target /
7、这时，你可以先大肆地进行参数，例如，执行list backup of database;，然后看看结果是否和你臆想的一样？思考下why？
8、在目标库执行startup nomount;
9、咦？居然Oracle instance started？？？纳尼？为什么没参数文件都可以启动？什么鬼？db_name=DUMMY是什么情况？
10、下面开始进坑：
首先是恢复参数文件：
（下边这个run代码块我也是拿来主义的，里边有坑，先不说，君请继续往下看）

what？还报错？
RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece
什么情况？
这时，怎么办？你说怎么办？当然百度、谷歌什么的啦？没错，我也是这么搞的。
我还找到我可以理解的blog：https://www.cnblogs.com/pengineer/p/4558395.html
关键信息：
1、CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; 后面的default没有的，但是值还是不变
2、nomount状态下只能看到RMAN最原始的配置信息
再看看当前目标库的rman配置：
RMAN> show all;

一直说RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece
我又百度了一轮。。。。。
网上说的基本都差不多，类似这篇http://blog.51cto.com/407882/282259
所以，与我遇到的并不一样。
此时，我的内心是崩溃的。。。
于是，想直接restore spfile from '';
把所有备份集都试：

可以看到，一直是无法找到备份或指定的是无效的备份集，明明是有的。
乱试了一番后，突然想到会不会是权限问题？？？
检查发现，从源库传过来用的是root用户，所有文件的所属者都是root，晕。。。
所以，执行：chown oracle:oinstall /u01/backup/
RMAN> restore spfile to '/u01/app/oracle/product/12.2.0/db_1/dbs/initorcl.ora' from '/u01/backup/o1_mf_s_963437820_f3t2mwz5_.bkp';

这里居然报错，一开始我也不清楚原因，后来发现，是前边restore spfile to时少加了pfile，导致创建出来的pfile实际是spfile，spfile不是普通文本，当oracle找到pfile后发现有无效字符串（乱码），所以报错。。。
