前段时间对数据库进行了调整，把REDOLOG FILE的位置从RAID5的磁盘移到了RAID0下，从A 分区移到了B分区，并改变了其大小。根据以下的一篇文档，在STANDBY上进行相关操作：
Another example of a change on the primary that requires user intervention on the standby is any command that adds or alters online redo logs. While is it technically not necessary to keep the online redo logs the same between the primary and standby site, it is a good practice. Once you have added or dropped the online redo log on the primary, perform the following on the standby to bring it back into sync with the primary:

Step 1.  Stop managed recovery.

alter database recover managed standby database cancel;
Step 2.  Set the STANDBY_FILE_MANAGEMENT parameter to MANUAL.

alter system set standby_file_management=manual;
Step 3.  Issue the SQL to drop or add the online redo log on the standby database.

Step 4.  Set standby_file_management to AUTO.

alter system set standby_file_management=auto;
Step 5.  Restart managed recovery with the original options.

Be aware that if you add an online redo log on the primary, you should also add a standby redo log on the standby and primary to maintain the correct number to ensure their use.


在进行第三步的时候，报如下错误：

难道还有一些参数要进行修改吗？？
