修改DG參數：

SQL> alter system set log_archive_config='';

關閉資料庫後，重新啟動：

SQL> startup pfile='$ORACLE_HOME/dbs/hua.ora';
ORACLE instance started.

同時，檢查alert.log裡有以下錯誤：

Errors in file /u01/app/oracle/admin/icssfcdb/bdump/icssfcdb_lgwr_7882.trc:
ORA-16072: a minimum of one standby database destination is required

mount狀態下，檢查相關參數狀態：

[oracle@icssfcdb bdump]$ sqlplus / as sysdba
