取得ipc信息：
ipcs [-m|-q|-s]
-m     输出有关共享内存(shared memory)的信息
-q      输出有关信息队列(message queue)的信息
-s      输出有关“遮断器”(semaphore)的信息
# ipcs -m
IPC status from <running system> as of 2007年04月10日 星期二 18时32分18秒 CST
T         ID      KEY        MODE        OWNER    GROUP
Shared Memory:
m          0   0x50000d43 --rw-r--r--     root     root
m        501   0x1e90c97c --rw-r-----   oracle      dba
#ipcs |grep oracle|awk   '{print $2}
   501

删除ipc(清除共享内存信息)
ipcrm -m|-q|-s shm_id
%ipcrm -m 501
for i in `ipcs |grep oracle|awk   '{print $2}'`
do
ipcrm -m $i
ipcrm -s $i
done

ps -ef|egrep "ora_|asm_"|grep -v grep |grep -v crs|awk '{print $2}' |xargs kill -9
