查看隐含参数脚本

可以使用如下脚本

SELECT x.ksppinm NAME, y.ksppstvl VALUE, x.ksppdesc describ

FROM SYS.x$ksppi x, SYS.x$ksppcv y

WHERE x.inst_id = USERENV ('Instance')

AND y.inst_id = USERENV ('Instance')

AND x.indx = y.indx

AND x.ksppinm LIKE '%&par%'

/

例如我要查看 _shared_pool_reserved_min_alloc隐含参数

Enter value for par: _shared_pool_reserved_min

old 6: AND x.ksppinm LIKE '%&par%'

new 6: AND x.ksppinm LIKE '%_shared_pool_reserved_min%'

NAME VALUE DESCRIB

----------------------------------- ---------- ------------------------------

_shared_pool_reserved_min_alloc 4100 minimum allocation size in bytes for reserved area of shared pool

修改隐含参数

SQL> alter system set "_shared_pool_reserved_min_alloc"=4400 scope=spfile;

System altered
