dragon1 ps -efgrep oracle9grep _rac1grep -v grepawk '{print "kill -9 "$2}' mykill
dragon1. ./mykill
dragon1 ipcs -m
Shared Memory:
T ID KEY MODE OWNER GROUP
m 128 0 --rw-r----- oracle8 dba
m 129 0 --rw-r----- oracle8 dba
m 130 0xe9d0aaa8 --rw-r----- oracle8 dba
m 1027 0 --rw-r----- oracle9 dba
m 1028 0xe0bb589c --rw-r----- oracle9 dba
dragon1 ipcrm -m 1027
dragon1 ipcrm -m 1028
然后就可以起来了。
