Oraclestandby库的ORA-01274问题

在standby数据库中，初始化参数STANDBY_FILE_MANAGEMENT设置为MANUAL环境中，当主库新建一个数据文件时，它MRP进程中止，后台介质

在standby数据库中，初始化参数STANDBY_FILE_MANAGEMENT设置为MANUAL环境中，当主库新建一个数据文件时，它MRP进程中止，，后台介质恢复工作失败。这是因为standby数据库不能自动创建新文件，参数配置决定了。

在alert.log中，日志信息如下：

解决方法很简单，很简单。

SQL> alter database create datafile '/u01/app/oracle/product/10.2.0/db/dbs/UNNAMED00012' as '+VG1/lbesup/lb_7881_data01.dbf';

Database altered.

然后启用恢复进程，问题解决。
