查询含resize的隐含参数：

 select a.ksppinm name,b.ksppstvl value,a.ksppdesc description
   from x$ksppi a,x$ksppcv b
  where a.inst_id = USERENV ('Instance')
    and b.inst_id = USERENV ('Instance')
    and a.indx = b.indx
    and upper(a.ksppinm) LIKE upper('%&param%')
 order by NAME;

 NAME                           VALUE        DESCRIPTION
 -------------------------------------------------- -------------------- ----------------------------------------------------------------------------------------------------
 _asm_skip_resize_check                   FALSE        skip the checking of the clients for s/w compatibility for resize
 _bct_public_dba_buffer_dynresize           2            allow dynamic resizing of public dba buffers, zero to disable
 _disable_file_resize_logging               FALSE        disable file resize logging to alert log

可以发现_disable_file_resize_logging参数默认值为false,表示显示文件resize的提示,设置为true应该就可以解决该问题.

 SQL> alter system set "_disable_file_resize_logging"=TRUE scope=spfile sid='*';

 System altered.
