清除dg配置重啓主庫出現ORA-03113和ORA-16072錯誤

用戶準備清除dg,單機運行,但我清除主庫的dg相關參數後,啓動數據庫報:

ORA-03113

SQL> startup;

ORACLE instance started.

Total System Global Area 2147483648 bytes

Fixed Size 1220460 bytes

Variable Size 452984980 bytes

Database Buffers 1677721600 bytes

Redo Buffers 15556608 bytes

Database mounted.

ORA-03113: end-of-file on communication channel

檢查alert.log日誌錯誤信息:

LGWR: Primary database is in MAXIMUM AVAILABILITY mode

LGWR: Destination LOG_ARCHIVE_DEST_1 is not serviced by LGWR

LGWR: Minimum of 1 synchronous standby database required

緣由是最大性能模式(最大保護模式也同樣)要求備庫是可通訊的, 而原先只是把備庫幹掉了, 但沒有把保護模式

作更改, 因此主庫重啓會有錯誤. 如今只要在打開數據庫前把改成最大性能模式便可.
