问题分析：
ORA-00600: internal error code, arguments: [4136]这类问题基本都是由于undo段的问题，由于存储或断电当机故障操事务，如需要recover。
处理思路：
备份参数文件：
SQL>create pfile =’/home/oracle/xt2.ora’ from spfile;
修改pfile文件
*.undo_management='MANUAL'
#*.undo_tablespace='UNDOTBS1'
*.undo_tablespace='SYSTEM'
rollback_segments='SYSTEM'
启动数据库
Startup pfile=’/home/oracle/xt2.ora’
查看rollback segment状态
Select tablespace_name,status,segment_id,segment_name from dba_rollback_segs;
可以看到15,14回退段需要recover，再次关闭数据库，在参数文件里添加：
_CORRUPTED_ROLLBACK_SEGMENTS =( SYSSMU15_2717915580$,_SYSSMU14_431226599$)
_offline_rollback_segments=(_SYSSMU15_2717915580$,_SYSSMU14_431226599$)
SQL>startup pfile=’/home/oracle/xt2.ora’
方法一：
如果只是某个undo段有问题，而不想删除原来的undo表空间，可以采用下面的方法
SQL> drop rollback segment "_SYSSMU14_431226599$";
SQL> drop rollback segment "_SYSSMU15_2717915580$";
SQL>Create spfile from pfile=’/home/oracle/xt2.ora’
SQL>Shutdown immediate;
SQL>Startup;
方法二：
删除原来的undo表空间，并在参数文件里指定新的表空间
SQL> drop tablespace undotbs1 including contents and datafiles;
SQL>create undotbs02 tablespace datafile size 10g;
修改参数文件：
*.undo_tablespace='UNDOTBS02'
*.undo_management='AUTO'
重启数据库
SQL>Startup pfile=’/home/oracle/xt2.ora’
SQL>Create spfile from pfile=’/home/oracle/xt2.ora’
SQL>Shutdown immediate;
SQL>Startup;
