二、MOS记录
ERROR: ORA-600 [4194] [a] [b] VERSIONS: versions 6.0 to 10.1 DESCRIPTION: A mismatch has been detected between Redo records and rollback (Undo) records. We are validating the Undo record number relating to the change being applied against the maximum undo record number recorded in the undo block. This error is reported when the validation fails. ARGUMENTS: Arg [a] Maximum Undo record number in Undo block Arg [b] Undo record number from Redo block
三、解决办法
1、修改参数
undo_management= MANUAL
undo_tablespace= SYSTEM
2、打开数据库，删除当前undo空间，重建新undo空间
3、修改参数
undo_management= AUTO
undo_tablespace= UNDOTBSNEW
4、重新启动数据库
