前几日一数据库实例alert日志中出现了ORA-600 [kpncxcc-1], kpn开头的函数通常用于服务器之间通信, 从trace中也可以发现是一条调用了dblink的select, 在MOS未发现已知BUG.
ERROR:
ORA-00600: internal error code, arguments: [kpncxcc-1], [12], [5], [7], [], [], [], [], [], [], [], []

My db env Oracle 9.2.0.6 on SunOS 5.10, during the problem occurs Database hang, and many sessions wait ‘libaray cache lock’ and after awhile sqlplus connect failed, Before the problem occurs ,We to a statspack, and explain plan for sql, but the sql did not use parallel and db_link, and select on v$sql_plan

Errors in file /oracle/app/oracle/diag/rdbms/anbob/anbob1/trace/anbob1_pmon_15074000.trc:
ORA-00600: internal error code, arguments: [kcbo_switch_cq_1], [], [], [], [], [], [], [], [], [], [], []
PMON (ospid: 15074000): terminating the instance due to error 472

因为某些原因数据字典表不一致，导到该表在查询或导出时都会提示ora-600 [kkpo_rcinfo_defstg:delseg] 错误，因为数据库使用延迟段创建，手动分配segment时提示ORA-600 [25027],对分区做MOVE时会提示ORA-600 [ktadrprc-1]， 使用hcheck脚本检查会提示Orphaned TABPART$

前两天一同事的数据库alert log不停的在刷出ora-600 [ktbdchk1: bad dscn]错误，影响的是一张table上的insert语句， 前不久该数据库存储出现过故障，从已知BUG中没有找到相似案例，这里只是简单的记录一下问题的处理过程。

ORA-00600: internal error code, arguments: [kghstack_alloc], [define handles], [], [], [], [], [], [], [], [], [], []
***** Current SQL Statement for this session (sql_id=5udxh0ykgshkb) *****
select location_name, max(r.reg_id) from reg$ r left outer join gv$subscr_registration_stats

前段时间数据库出现了几次ORA 600 [ktspfmdb:objdchk_kcbnew_3]错误，引起该错误的是一条insert sql.

Problem Key: ORA 600 [k2srec: should be another instance]
Error: ORA-600 [k2srec: should be another instance] [2] [] [] [] [] [] [] [] [] [] [][00]
with the following stack :k2srec <- k2serv <- opiodr <- ttcpip

二个月前一套CRM 的10.2.0.5 rac on hpux 的alert 中发现了ora-600 17114 , 从trace file 中发现是查询v$session, 随后在MOS中找到了bug 导致， call stack 一致，简单记录一下。

今天同事的一套数据库遇到了alert 日志 一堆的ora-600，这是一套10.2.0.5 db 2nodes RAC on AIX , 找我帮着看看， 最终确认为一个索引出现了block corrupted 勘误块导致， 重新创建的了索引后解决…
