各位好:
我现在想在 RHEL5 OS环境下的 11.2.0.1.0 的双节点RAC环境到单实例(也是11.2.0.1.0,单实例备库也使用ASM磁盘组)的DataGuard,但在主库执行:
rman target / auxiliary sys@stdb
RMAN > duplicate target database for standby nofilenamecheck;
后,提示如下错误:

ORA-17502: ksfdcre:5 Failed to create file +DATA/stdb/controlfile/control01.ctl

并且在备库RMAN中执行 restore standby controlfile from '/backup/rman_bak/dg_bak/racdb_ctl_0apqgkc8_1_1_20141218';
也是提示和以上一样的错误。并且我预先在+DATA磁盘组中创建stdb/controlfile目录也不行。
