ora-00600[25027]错误的触发原因是oracle检测到一个无效的表空间号tsn tablespace number或者相对文件号relative file number。 该ORA-00600[25027]的2个变量各代表： arg[a] Tablespace Number表空间号 arg[b] 十进制的相对数据块号Relative Data Block Add
ora-00600[25027]错误的触发原因是oracle检测到一个无效的表空间号tsn tablespace number或者相对文件号relative file number。
该ORA-00600[25027]的2个变量各代表：
arg[a] Tablespace Number表空间号
arg[b] 十进制的相对数据块号Relative Data Block Address (RDBA)
该ORA-00600[25027]错误相关的模块为Kernel File management Tablespace component，其影响为可能的物理块损坏。
当该错误触发后 如果 arg[b] 即RDBA为0，则该错误可能由于索引问题引起。
可以使用如下查询来获得有问题的索引：
select do.owner,do.object_name, do.object_type,sysind.flags
from dba_objects do, sys.ind$ sysind
where do.object_id = sysind.obj#
and bitand(sysind.flags,4096)=4096;如果上面的查询返回了数据行，则建议用户进一步检查查询所获得的对象，并考虑drop这些对象来绕过错误。
进一步可以对trace文件中指向的表做一个analyze table validate structure cascade，来进一步确认该问题。
