RMAN duplicate from active 时遭遇 RMAN-04017和ORA-00439:ORA-00439: feature not enabled: Real Application Clusters

 报错信息：

RMAN-03002: failure of Duplicate Db command at 10/08/2018 11:13:26

RMAN-05501: aborting duplication of target database

解决：duplicate命令加上：set cluster_database='false'，如下：

duplicate target database 

for standby nofilenamecheck

from active database 

DORECOVER 

spfile 

set db_unique_name='htzxdbphy'

set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST valid_for=(ALL_LOGFILES,ALL_ROLES) db_unique_name=htzxdbphy'

set log_archive_dest_2='service=tns_htzxdbpri async lgwr register valid_for=(online_logfile,primary_role) db_unique_name=htzxdbpri'

set standby_file_management='AUTO'

set fal_server='tns_htzxdbpri'

set fal_client='tns_htzxdbphy'

set control_files='+DATA','+DATA'

set db_file_name_convert='+DATA','+DATA'

set log_file_name_convert='+DATA','+DATA'

set memory_target='2048M'

set audit_file_dest='/u01/app/oracle/admin/htzxdb/adump'

set db_create_file_dest = '+DATA'

set db_recovery_file_dest = '+FRA'

set cluster_database='false'

;

由于主库是  rac  ，备库是单实例，所以，一定需要设置    cluster_database   ='false'。
