环境
备库standby_file_management参数为MANUAL
主库创建数据文件时备库应用失败
主库
SQL> create tablespace test datafile '+DATA/dgpri/datafile/test01.dbf' size 50m;
备库开启实时应用
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;
查看日志

此时备库执行
SQL> alter database create datafile '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/UNNAMED00006' as '+DATA/dgphy/datafile/test01.dbf'; Database altered.
再开启实时应用
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION; Database altered.
