大量Resize operation completed for file# 操作记录,给人感觉比较烦,根据多年使用oracle的经验,这种现象很可能有隐含参数或者event屏蔽,隐含参数可以猜测到,event需要查询官方资料.

查询汗resize的隐含参数

SQL> col name for a52
SQL> col value for a24
SQL> col description for a50
set linesize 150
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
SQL> SQL>   2    3    4    5    6     and upper(a.ksppinm) LIKE upper('%¶m%')
  7  order by name
/
  8  Enter value for param: resize
old   6:    and upper(a.ksppinm) LIKE upper('%¶m%')
new   6:    and upper(a.ksppinm) LIKE upper('%resize%')
 
NAME                                                 VALUE                    DESCRIPTION
---------------------------------------------------- ------------------------ --------------------------------------------------
_asm_skip_resize_check                               FALSE                    skip the checking of the clients for s/w compatibi
                                                                              lity 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

从这里可以发现_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.
