ORA-600(kposcws-2)错误

客户11.2.0.2 RAC环境出现ORA-600[kposcws-2]错误。
错误信息为:

Thu Sep 27 10:48:15 2012
Errors IN file /u01/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_ora_34145026.trc  (incident=682292):
ORA-00600: 内部错误代码, 参数: [kposcws-2], [], [], [], [], [], [], [], [], [], [], []
Incident details IN: /u01/app/oracle/diag/rdbms/orcl/orcl1/incident/incdir_682292/orcl1_ora_34145026_i682292.trc

根据MOS文档Bug 6615409 – ORA-600 [kposcws-2] on scrollable cursor [ID 6615409.8],导致问题是由于使用了scrollable游标。
不过这个BUG应该在10.2.0.5和11.2.0.1中已经被修正,虽然问题在11.2.0.2中重现的可能性不大,但是根据已知的BUG描述,似乎BUG重现是最合理的解释。
由于没有11.2.0.2上问题出现的描述,因此也不会存在单独的补丁,唯一可以尝试的版本就是将数据库版本升级到11.2.0.3以上。
