在linux下查看有哪些操作系统进程正在使用某一个共享内存段
[root@abc log]# ipcs -m
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x0052e2c1 0 highgo432 600 56 5
0x00000000 65537 oracle 640 12582912 26
0x00000000 98306 oracle 640 511705088 26
0x0447bbc8 131075 oracle 640 2097152 26 那怎么找到是哪26个进程呢？使用如下命令即可：
[root@abc log]# lsof | egrep "65537"
