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.
