11g生产数据库crsctlstarthas无法启动故障处理
以下内容为模拟操作，因为客户核心数据库是不允许把日志拿出来的哈。
不过处理过程和思路几乎是一样的。

一、故障描述
11G RAC -单机ADG,备端HAS服务无法启动。
二、现象
查看了集群的各种日志，均无任何日志输出。
[root@roidb2 bin]# pwd
/u01/app/11.2.0/grid/bin
[root@roidb2 bin]# ./crsctl start has
[root@roidb2 bin]# --无输出，不提示报错，也不提示成功启动
[root@roidb2 bin]# 怎么办，怎么办？第一次遇到这样的问题。问了客户，说了周五做了搬迁工作，难道是磁盘出了问题，还是权限出了问题。按照这个思路查了一遍，也没有什么发现。回过头来，整理了一下思路，使用strace来看一下，也许会有意想不到的收获。
[root@roidb2 bin]# strace ./crsctl start has
execve("./crsctl", ["./crsctl", "start", "has"], [/* 28 vars */]) = -1 ENOEXEC (Exec format error) --格式错误
dup(2) = 3
fcntl(3, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7ff367e29000
lseek(3, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "strace: exec: Exec format error\n", 32strace: exec: Exec format error
) = 32
close(3) = 0
munmap(0x7ff367e29000, 4096) = 0
exit_group(1) = ?
[root@roidb2 bin]# 为什么会是这样的报错，难道是文件又问题？继续往下查..........
[root@roidb2 bin]# ls -l crsctl
-rwxr-xr-x 1 root root 0 Dec 11 20:54 crsctl
[root@roidb2 bin]# file crsctl
crsctl: empty --竟然是空文件！！！！！！！
[root@roidb2 bin]# 怎么办，怎么办？我们知道这是一个脚本文件，那么，我们从其他节点copy一个文件怎么样呢？
三、处理过程
--远程传输一个文件过来呗
$scp /u01/app/11.2.0/grid/bin/crsctl root@192.168.1.212:/u01/app/11.2.0/grid/bin/
root@192.168.1.212's password:
crsctl 100% 8574 8.4KB/s 00:00
$ [root@roidb2 bin]# file crsctl
crsctl: POSIX shell script text executable
[root@roidb2 bin]# ./crsctl start has
CRS-4123: Oracle High Availability Services has been started.
[root@roidb2 bin]#
--搞定--学习官方都怎么写脚本
[root@roidb2 bin]# cat crsctl
#!/bin/sh

# - This script should only use clsecho.bin directly and not clsecho(which is
# this same script).
# - FIXME: crswrap should process hostname locally as well just like init.ohasd.

[root@roidb2 bin]# 小结：
1.数据库、主机的启停一定要正常步骤进行，切记直接断电。
2.搬迁之前，做好备份工作，移动安装设备要注意轻拿轻放。
