处理流程如下：
查看数据库日志报错：
ORA-00600: internal error code, arguments: [ktspfupdst-1], [], [], [], [], [], [], [], [], [], [], []
Incident details in: /home/oradba/oracle/diag/rdbms/yjfcdbp/yjfcdb/incident/incdir_192162/yjfcdb_smon_17351_i192162.trc
Use ADRCI or Support Workbench to package the incident.
See Note 411.1 at My Oracle Support for error and packaging details.
Non-fatal internal error happenned while SMON was doing logging scn->time mapping.
SMON encountered 2 out of maximum 100 non-fatal internal errors.
System state dump requested by (instance=1, osid=17307 (PMON)), summary=[abnormal instance termination].
System State dumped to trace file /home/oradba/oracle/diag/rdbms/yjfcdbp/yjfcdb/trace/yjfcdb_diag_17323.trc
Dumping diagnostic data in directory=[cdmp_20141030070534], requested by (instance=1, osid=17307 (PMON)), summary=[abnormal instance termination].
Instance terminated by PMON, pid = 17307
查看trace文件发现错误语句如下：
insert into smon_scn_time (thread, time_mp, time_dp, scn, scn_wrp, scn_bas, num_mappings, tim_scn_map) values (0, :1, :2, :3, :4, :5, :6, :7)
出现原因：
smon_scn_time表中的索引逻辑损坏
进行处理
首先对smon_scn_time进行结构验证，没有问题
SQL> conn / as sysdba
SQL> ANALYZE TABLE smon_scn_time VALIDATE STRUCTURE;
Table analyzed.
然后对涉及的索引进行验证报错：
SQL> ANALYZE TABLE smon_scn_time VALIDATE STRUCTURE CASCADE ONLINE;
ERROR at line 1:
ORA-01499: table/index cross reference failure - see trace file
然后对涉及的索引进行重建
SQL> ALTER INDEX SMON_SCN_TIME_TIM_IDX REBUILD ONLINE;
SQL> ALTER INDEX SMON_SCN_TIME_SCN_IDX REBUILD ONLINE;
重建后可以进行验证
SQL> ANALYZE TABLE smon_scn_time VALIDATE STRUCTURE CASCADE ONLINE;
Table analyzed.
但是查看日志报错任然有ORA600错误，但是语句报错已经消失
然后处理如下：
SQL> conn / as sysdba
停止SMON 写入 smon_scn_time表
SQL> alter system set events '12500 trace name context forever, level 10';
SQL> truncate cluster SMON_SCN_TO_TIME_AUX;
Cluster truncated
启动SMON 写入 smon_scn_time表
SQL> alter system set events '12500 trace name context off';
再次查看日志没有报错。
SCN=(SCN_WRP * 4294967296) + SCN_BAS
