ORA-00600: internal error code, arguments:[kcbgcur_9]

ORA-600 [kcbgcur_9]错误的触发原理是当 buffer被以某种类型顺序pin住以便防止内部死锁时，发现当前buffer被以错误的类型顺序pinned或者同一class中有重复的buffer；也可能在更新只读表空间时与ORA-372错误一起发生。
该ORA-600 [kcbgcur_9]错误隶属于内核 buffer cache模块

这个ORA-600 [kcbgcur_9]错误一般有4个argument:

Arg [a] The Database Block Address (DBA)
Arg [b] The buffer class
Arg [c] Block class order mask
Arg [d] Block class checking mask

ORA-600 [kcbgcur_9]错误可能的影响是造成进程失败，但一般不会造成数据块的损坏

ORACLE SUPPORT对遇到该问题的主要建议是检查所有的系统硬件磁盘和内存，以便保证不是底层系统造成了该问题。
