1、將數據關閉 svrmgrl >Shutdown abort 2、修改初始化參數文件 $ vi $Oracle_HOME/dbs/init< sid >.ora 添加以下參數 rollback_segments=(system) _corrupted_rollback_segments=(r01,r02,r03,r04) _allow_resetlogs_corruption=ture 3、重新裝載數據庫 svrmgrl >Startup mount 4、從數據庫的控制文件中將回滾段表空間rbs的數據文件離線并去掉。 svrmgrl >alter database datafile ‘##/##/rbs01.dbf’ offline drop; ---- 對數據庫進行恢復。 svrmgrl >recover database using backup controlfile; ---- 此時屏幕上可能會出現： ORA_00280 Change #### for thread# is in sequence# specify log:[< RET > for suggestedAUTOfrom logsourcecancel] 輸入 cancel(不要輸入其他命令) svrmgrl >alter database open resetlogs; 5、 重建新的回滾段 ---- 將舊回滾段及回滾表空間刪除。 svrmgrl >alter rollback_segment r01 offline drop; svrmgrl >alter rollback_segment r02 offline drop; svrmgrl >alter rollback_segment r03 offline drop; svrmgrl >alter rollback_segment r04 offline drop; svrmgrl >drop tablespace rbs including contents; ---- 重建新的回滾表空間及回滾段。 svrmgrl >connect internal svrmgrl >create rollback segment ro tablespace system; svrmgrl >alter rollback segment ro online; svrmgrl >create tablespace rbs datafile ##/##/rbs01.dbf’ size ##k; svrmgrl >create rollback segment r01 tablespace rbs; svrmgrl >create rollback segment r02 tablespace rbs; svrmgrl >create rollback segment r03 tablespace rbs; svrmgrl >create rollback segment r04 tablespace rbs; svrmgrl >alter rollback segment r01 online; svrmgrl >alter rollback segment r02 online; svrmgrl >alter rollback segment r03 online; svrmgrl >alter rollback segment r04 online; svrmgrl >Shutdown abort $ vi $ORACLE_HOME/dbs/init< sid >.ora rollback_segments=(r01,r02,r03,r04) 將參數_corrupted_rollback_segment _allow_resetlogs_corruption=true去掉 svrmgrl >Startup normal
