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
