ora-00600[kcbzwfcro_2]

调整表空间，再增加dbf过程中报了ora-00600[kcbzwfcro_2]的报错，执行到报错的dbf自动扩展关闭了，手动调整还是报ora-00600，请问怎么解决

AWR中存在force-cr-override flush等待事件：

这是Oracle的一个BUG，Bug 16863642    SPACE: ORA-600[kcbzwfcro_2] seen for force-cr-override buffer.

解决方案如下：

1、Flush buffer cache OR to restart the instance

2、Set "_gc_override_force_cr=false" to avoid this particular issue:
SQL> alter system set "_gc_override_force_cr"=false scope=both sid='*';
