Suspending MMON slave action kewfmadsa_ for 82800 seconds
这个信息表示MMON slave进程异常了,82800是受下面隐含参数控制的:
SYS@bb>select ksppinm, ksppstvl, KSPPDESC
2 from x$ksppi pi, x$ksppcv cv
3 where cv.indx=pi.indx and pi.ksppinm like '\_%' escape '\'
4 and pi.ksppinm like '%kebm_suspension%';
KSPPINM KSPPSTVL KSPPDESC
------------------------------ --------------- -------------------------------------------------------
_kebm_suspension_time 82800 kebm auto suspension time in seconds
SYS@bb>
1,你可以kill掉mmon和mxxx进程(mmon slave进程)
2,你可以trave mmon和snapshot flush的相关活动,从而具体定位哪一类问题或者bug导致的方法如下:
开启:
alter session set "_swrf_test_action" = 28;
alter session set "_swrf_test_action" = 10;
关闭:
alter session set "_swrf_test_action" = 29;
alter session set "_swrf_test_action" = 11;
