从上面的结果，也知道是什么原因了，从内存来创建PFILE,会把一些隐含参数也写进来。
我这里的默认值是：
_compression_compatibility='11.2.0.0.0'
而朋友这里的默认值是：
_compression_compatibility='11.2.0.1.0'
这个参数就是朋友数据库启动报：ORA-00600: internal errorcode, arguments: [kck_rls_check must use （11,0,0,0,0） or lower] 错误的原因。
将这个参数改成：_compression_compatibility="11.2.0",在启动数据库，即可正常。
实际上，这个问题是Oracle 11g 中遗留的一个小问题。 在11.2.0.1 和11.0.2.0.2 中都会有这种问题。
在Oracle 11.2.0.3的版本中，这个_compression_compatibility参数的默认值就是11.2.0.0.0了，那么在从内存创建pfile,就不会在报ORA-600的错误了。
这也是我创建启动没报错，朋友启动创建启动报错的原因，因为我的数据库版本是11.2.0.3的。
还有一点，就是我们使用内存创建数据库参数的时候，可以把前面的隐含参数全部删除掉，哪些参数太繁琐了，使用默认值就好。
