DG duplicate报错:RMAN-05001:auxiliary file name /u01/app/oracle/oradata/fratbs01.dbf conflicts with a file used by the target database

问题：rman duplicate时报错：

RMAN-05001:auxiliary file name /u01/app/oracle/oradata/fratbs01.dbf conflicts with a file used by the target database

分析：应该是主库的这个数据文件位置没有在参数里面做转换

解决：

1）更改参数DB_FILE_NAME_CONVERT

查看原来参数配置：(vi initSBDB1.dbf)

DB_FILE_NAME_CONVERT='SBDB1','PROD1'      （默认所有的主备库路径

把报错数据文件文件转换加入DB_FILE_NAME_CONVERT

更改为：DB_FILE_NAME_CONVERT='SBDB1','PROD1','/u01/app/oracle/oradata','/u01/app/oracle/oradata/SBDB1'

2）把备库关闭，创建spfile文件，重启到nomount状态

shu immediate;                      create spfile from pfile;          startup nomount;

3）主库重新执行duplicate命令，成功

rman target / auxiliary sys/oracle@sbdb1

duplicate target database for standby from active database;
