实用小技巧-通过duplicate恢复rman备份并实现自动重命名数据文件路径
1、实验的起因
昨天晚上，群里雨哥说，他有个异机备份恢复测试要做，但是备份的原库和目标端的数据文件目录都不一样，需要一个一个set name修改脚本，但是数据文件+日志文件有几百个，改起来很麻烦。
于是我想起来做dg的时候，在备库通过duplicate+conver参数，实现了文件自动重命名的操作，但是讨论并且测试了一下，在要恢复的库上创建参数文件时写了convert参数，用rman restore的时候，convert不会生效，还得手动改set name才行。
查阅了相关的官方文档、MOS里，也确实是说了，下convert只能用duplicate时候才生效。
经过王也大哥提点，发现共有以下两种方法可以实现：
方法1：
Perform Backup Based RMAN DUPLICATE Without Connecting To Target Database For Both Disk & Tape Backups (Doc ID 1375864.1)
方法2
RMAN: SET NEWNAME Command Using SQL (Doc ID 549972.1)
参照以上方法，进行了一下测试实验，并进行一下比对。
如果只是想要通过原库搭建1个测试库，也可以通过网络duplicate,之前也有小伙伴写过用duplicate来搭建测试库的过程。

2、测试准备环境
2.1、模拟环境说明
原库环境：
ORACLE 11.2.0.4 RAC
ORACLE LINUX 6.9操作系统
数据文件路径+DATA恢复机环境
ORACLE 11.2.0.4 单机
ORACLE LINUX 6.9操作系统
数据文件路径/u01/app/oracle/oradata/orcl2.2、原库相关文件查看
原库数据文件位置
原库TEMP文件位置
原库日志文件位置
2.3、进行备份
使用oracle创建下备份目录
mkdir -p /u01/rman在RAC1节点登录rman进行备份，脚本如下
RMAN> run
{
allocate channel c1 type disk format '/u01/rman/%I-%Y%M%D-%U';
backup as compressed backupset incremental level 0 tag 'duplicate' check logical database plus archivelog;
release channel c1 ;
}2> 3> 4> 5> 6>
using target database control file instead of recovery catalog
allocated channel: c1

2.5、拷贝备份文件到要恢复的主机
2.6、在恢复主机上进行恢复准备环境
创建备库监听文件，静态监听。

3、使用方法1测试
3.1、进行duplicate恢复
进行恢复操作，操作在是RAC1节点进行备份的，备份的最后归档日志SCN号如下
List of Archived Logs in backup set 15
Thrd Seq Low SCN Low Time Next SCN Next Time
---- ------- ---------- --------- ---------- ---------
1 139 2534599 07-DEC-23 2534722 07-DEC-23
2 105 2534605 07-DEC-23 2534719 07-DEC-23从结果上看duplicate 会恢复到最后2节点最后1个归档的next SCN也就是 set until scn 2534719(这里应该是一致性的SCN)
之后自动open resetlogs打开数据库完成恢复。
主要执行恢复的有效命令是：
rman auxiliary /

3.2、恢复后校验
检查文件是否自动转换
standby redolog 没有带过来
大功告成！
4、使用方法2测试
4.1、进行rman恢复
在备份节点RAC1上查看一下控制文件在哪个备份片里
去恢复节点，进行恢复控制文件，启动库到mount模式。
run{
restore controlfile from '/u01/rman/1613952925-20231207-172df6a5_1_1';
sql 'alter database mount';
}执行结果

5、两个方法总结，比对分析
1、两种方法都能完成自动重命名文件的功能；
2、方法1其实只要事先在参数文件里加上convert参数，恢复也只需要1条命令，就能自动修改文件名、恢复到最后的SCN；duplicate不会恢复standby redolog；
3、方法2需要先手动恢复控制文件、再注册备份片、再恢复到批定的SCN，然后再open resetlogs(当然这堆也可以考虑写到1个脚本里)；
4、相比来说方法1采用duplicate更省心，一步到位。
6、注意的一些事
需要注意的是使用方法1恢复时
如果指定SCN进行恢复，会提示报错，按SCN恢复需要连target库或是catalog库
RMAN> DUPLICATE DATABASE TO orcl BACKUP LOCATION '/u01/rman/' NOFILENAMECHECK until scn 2534722;

RMAN-05501: aborting duplication of target database
RMAN-05542: Only UNTIL TIME can be used with DUPLICATE without TARGET and CATALOG connections如果指定时间进行恢复，而备份里没这些归档，那么会失败。
DUPLICATE DATABASE TO orcl BACKUP LOCATION '/u01/rman/' NOFILENAMECHECK UNTIL TIME "TO_DATE('07-DEC-2023 20:27:42','DD-MON-YYYYHH24:MI:SS')"
尝试输出如下：
