1.在目标端建立参数文件，并启动到nomount，如果测试库的文件存放路径和生产不一致，配置db_file_name_convert和log_file_name_convert

2.拷贝生产的密码文件到目标端，配置生产到目标端的tnsnames

3.配置目标端的监听为静态监听，参考如下：

SID_LIST_LISTENER=  

(SID_LIST =  

    (SID_DESC =  

      (global_dbname=orcl)     ##这个是 服务名

      (ORACLE_HOME =/u01/app/oracle/product/11.2.0/db_1)

      (SID_NAME =orcl)         ##这个是实例名

    )  

  )

4.在源端执行duplicate，可以从from active database或者使用 backup：

DUPLICATE TARGET DATABASE TO bre1 FROM ACTIVE DATABASE nofilenamecheck;

其中：bre1是db_name

[oracle@bre1 bre1]$ rman target sys/manager

Recovery Manager: Release 11.2.0.4.0 - Production on Mon Jan 29 10:42:10 2024

connected to target database: BRE1 (DBID=2718330383)

RMAN>  connect auxiliary sys/manager@bre2_test         ###这里bre2_test是生产到测试的tnsnames

connected to auxiliary database: BRE1 (not mounted)

RMAN> DUPLICATE TARGET DATABASE TO bre1 FROM ACTIVE DATABASE nofilenamecheck;

或者使用backup，需要先将backup的备份集拷贝到测试环境或者nfs共享挂载到测试环境：

DUPLICATE TARGET DATABASE TO bre1 backup location '/home/oracle/backup/file/20240129' nofilenamecheck;

5.dupllicate完成之后，默认duplicate数据库会后自动被open resetlogs，还可以指定时间点进行duplicate，例如

run{

set until time ='xxxxx';

duplicate target to xxxx;

}
