更改服务器名后crs无法启动解决

DB:oracle 11.2.0.2

OS:OEL Linux (OEL)5.6

现象：

更改hostnamenjdyw -> hotel07

重启服务器后发现crs服务无法启动

[oracle@hotel07 diag]$ crs_stat -t
CRS-0184: 无法与 CRS 守护程序通信。

[oracle@hotel07diag]$ crsctl start has
CLSU-00105: 操作系统接口报告了内部故障
CLSU-00103: 错误位置: scrcreate5
CLSU-00104: 其他错误信息: need ha priv
CRS-4000: 命令 Start 失败, 或已完成但出现错误。

解决办法：

重新配置crs安装，具体如下

--查看下面的目录，发现有之前服务器名的配置文件目录
[oracle@hotel07~]$ cd /etc/oracle/scls_scr
[oracle@hotel07 scls_scr]$ ls
njdyw

--在root用户下
--进到$GRID_HOME/crs/install目录，执行下面的脚本
[root@hotel07install]# pwd
/u01/app/ora11g/product/11.2.0/grid/crs/install
[root@hotel07install]# ./rootcrs.pl -deconfig -force
Usingconfiguration parameter file: ./crsconfig_params
用法: srvctl <command> <object> [<options>]
    命令:enable|disable|start|stop|status|add|remove|modify|getenv|setenv|unsetenv|config
    对象: database|service|asm|diskgroup|listener|home|ons

有关各个命令和对象的详细帮助, 请使用:

srvctl <command> -h 或
  srvctl <command> <object> -h

--然后再看crs配置目录
[oracle@hotel07~]$ cd /etc/oracle/scls_scr
[oracle@hotel07scls_scr]$ ls
hotel07

--查看crs状态
[oracle@hotel07 scls_scr]$ crs_stat -t

--如果缺少其它服务用srvctl命令进行添加

原文内容：

With 11.2 database, if thehostname is changed we’ll see following error while starting the HASservices

dev-srv-20:+ASM:/home/ora11gr2>crsctl start has

Failure at scls_scr_create with code 1

Internal Error Information:

Category: -1

Operation: has_ha_privs

Location: scrcreate5

Other: need ha priv

System Dependent Information: 0

CRS-4000: Command Start failed, or completed with errors.

To make sure, it is due to changein hostname check the directory in the following path. As we can see thehostname with which HAS was originally configured is different fromcurrent hostname.

dev-srv-20:+ASM:/etc/oracle/scls_scr>ls -al

total 0

drwxr-xr-x 3 root epsdba 80 2009-05-12 08:36 .

drwxr-xr-x 5 root epsdba 200 2010-03-08 14:27 ..

drwxr-xr-x 4 root epsdba 96 2009-05-12 08:36 dev-srv-25

So to fix the problem

1. De-configure the CRS
$GRID_HOME/crs/install/rootcrs.pl -deconfig -force
2. Reconfigure CRS
$GRID_HOME/crs/install/roothas.pl
