一朋友在QQ上问我,说他数据库的pfile 和spfile 都不见了。我问他数据库是10g还是11g的,他说11g,所以我就让他用这个语法来创建spfile了:
SQL> create spfile from memory;
这个是Oracle 11g的新特性,在我之前的Oracle 11g新特性里有介绍:
Oracle 11g 新特性 -- 管理 SPFILE 说明
http://blog.csdn.net/tianlesoftware/article/details/8225247
朋友用这种方法操作以后,启动数据库报错:
ORA-00600: internal errorcode, arguments: [kck_rls_check must use (11,0,0,0,0) or lower], [kdt.c], [9419], [11.2.0.1.0], [], [], [], [], [], [], [], []
创建一个pfile,还搞出一个ORA-600,有点邪门。 不过之前也没有好好研究这个从内存里创建PFILE的功能。
在自己的虚拟机上测试了一下:
SQL> create pfile='/u01/dave.ora' frommemory;
File created.
SQL> startuppfile='/u01/dave.ora';
ORA-32006: BACKGROUND_DUMP_DESTinitialization parameter has been deprecated

我这里用pfile 来启动,是没有报错的。 但是朋友那缺报了ORA-600的错误。

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。
