查看/etc/inittab以及/etc/init.d下面，并没有OEM的启动脚本（用ls –lrt 看一下即可） 查看/etc/rc.d，可以看到最下面三个好像有那么个意思，查看脚本内容，还真是。
[root@oradb2 rc.d]# pwd /etc/rc.d [root@oradb2 rc.d]# ls -lrt init.d/* -rwxr-xr-x 1 root root 1778 2006-07-12 init.d/gpm -rwxr-xr-x 1 root root 1877 2006-07-13 init.d/portmap …………………………………………………….. -rwxr-xr-x 1 root root 15208 12-16 20:15 init.d/vmware-tools-thinprint -rwxr-xr-x 1 root root 38525 12-16 20:15 init.d/vmware-tools -rwxr-xr-x 1 root root 128 12-16 21:31 init.d/lockgcstartup -rwxr-xr-x 1 root root 83 12-16 21:31 init.d/unlockgcstartup -rwxr-xr-x 1 root root 1745 12-16 21:31 init.d/gcstartup
查看rc*.d文件

将上述文件删除或者重命名，如果你以后还想用的话，就MV好了。这样再次开机的时候也就分分钟的事了。开机后进入/oracle/oem12c/oms/bin 目录，执行一下命令即可启动OEM（启动时间还是挺长的，耐心点）
