大家好!
由于磁盘阵列损坏,用户无法使用数据库,在alertlog中报:
Sat Apr5 16:41:24 2008
Errors in file /dba/oracle/admin/ENTDB/bdump/entdb_pmon_19472.trc:
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2: '/db5/rollback.dbf'
我通过svrmgrl接入后,无法 shutdownimmediate;最后shutdown abort。启动时报 ORA-01545: rollback segment 'RB6' specified not available
注释掉init文件中的rollback_segment后,系统可以正常启动,没有报错。
然后我对数据库做exp,4个表报错类似错:
. . exporting tableFND_CONCURRENT_REQUESTS
EXP-00014: error on row 11134 of table FND_CONCURRENT_REQUESTS
EXP-00008: ORACLE error 376 encountered
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2: '/db5/rollback.dbf'
