Oracle系统中还有一类参数称之为隐含参数(Hidden Parameters),在系统中使用,但Oracle官方没有公布的参数,这些参数可能是那些还没有成熟或者是系统开发中使用的参数。这些参数在所有Oracle官方提供的文档中都没有介绍,它们的命名有一个共同特征就是都以“_”作为参数的首字符。下面的查询可以得到当前系统中的所有隐藏参数,需要以SYS用户登陆,查看两个视图:X$KSPPI和X$KSPPCV。下面作者给出具体的SQL语句。
SET PAGESIZE 9999
SET LINE 9999
COL NAME FORMAT A40
COL KSPPDESC FORMAT A50
COL KSPPSTVL FORMAT A20
SELECT A.INDX,
A.KSPPINM NAME,
A.KSPPDESC,
B.KSPPSTVL
FROM X$KSPPI A,
X$KSPPCV B
WHERE A.INDX = B.INDX
AND A.KSPPINM LIKE '/_%' ESCAPE '/'
AND LOWER(A.KSPPINM) LIKE LOWER('%&PARAMETER%');
举个例子,如果需要查询隐含参数“_LM_DD_INTERVAL”的值,那么执行上面的代码后输入“_LM_DD_INTERVAL”就可以看到该隐含参数的值了,如下所示:
SYS@lhrdb> SET PAGESIZE 9999
SYS@lhrdb> SET LINE 9999
SYS@lhrdb> COL NAME FORMAT A40
SYS@lhrdb> COL KSPPDESC FORMAT A50
SYS@lhrdb> COL KSPPSTVL FORMAT A20
SYS@lhrdb> SELECT A.INDX,
2 A.KSPPINM NAME,
3 A.KSPPDESC,
4 B.KSPPSTVL
5 FROM X$KSPPI A,
6 X$KSPPCV B
7 WHERE A.INDX = B.INDX
8 AND A.KSPPINM LIKE '/_%' ESCAPE '/'
9 AND LOWER(A.KSPPINM) LIKE LOWER('%&PARAMETER%');
Enter value for parameter: _lm_dd_interval
old 9: AND LOWER(A.KSPPINM) LIKE LOWER('%&PARAMETER%')
new 9: AND LOWER(A.KSPPINM) LIKE LOWER('%_lm_dd_interval%')
INDX NAME KSPPDESC KSPPSTVL
---------- ---------------------------------------- -------------------------------------------------- --------------------
578 _lm_dd_interval dd time interval in seconds 10
可以看到该隐含参数的值为10。
对于隐含参数而言,修改隐含参数的值的时候需要将隐含参数用双引号括起来。若要清除SPFILE中的隐含参数可以使用RESET命令。
SYS@lhrdb> alter system set _lm_dd_interval=20 scope=spfile;
alter system set _lm_dd_interval=20 scope=spfile
*
ERROR at line 1:
ORA-00911: invalid character
SYS@lhrdb> alter system set "_lm_dd_interval"=20 scope=spfile;
System altered.
SYS@lhrdb> alter system reset "_lm_dd_interval" scope=spfile sid='*';
System altered.
普通用户是不具备查询隐含参数的权限的,可以通过创建视图和同义词的方式来解决这个问题,如下所示:
