前幾天RAC出現錯誤。引起Configuration 異常。

后調整RAC 的REDO文件大小。

今天看到STANDBY 端出錯，錯誤如下：

1、FRIMARY SERVER:

在RAC PRIMARY 端，先關閉日志同步。

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=defer;

System altered.

2.暫停STANDBY

SQL> alter database recover managed standby database cancel;

Database altered.

3.修改模式：

SQL> alter system set standby_file_management=manual;

System altered.

4.刪除并重新建立日志，

這里遇到一些問題，有些日志重啟STANDBY服務器及重啟/關閉日志同步2次后，再重新建立成功。

SQL> alter database drop logfile group 1;
alter database drop logfile group 1
