access$表在數據庫丟失的恢復

下面是測試一把access$基表丟失的恢復方法

 

歡迎你們加入ORACLE超級羣：17115662 免費解決各類ORACLE問題,之後BLOG將遷移到http://www.htz.pw

 

1，數據庫版本

www.htz.pw > select * from v$version;   BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE    11.2.0.3.0      Production TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production

2，啓動報錯

3，重建access$基表

建議的辦法很簡單，重啓到數據庫到upgrade模式，重建基表就能夠了。
